The Boss SX700 Studio Effects Processor stands as one of the most significant achievements in 1990s audio technology – a revolutionary 1U rack unit that fundamentally changed the landscape of affordable professional effects processing. Released in 1996 during the height of the digital audio revolution, this unassuming black box delivered groundbreaking spatial audio capabilities and professional-grade sound quality at a price point that democratized advanced studio effects for an entire generation of producers, engineers, and musicians.
More than just another multi-effects processor, the SX700 represented a paradigm shift in what could be achieved with budget-conscious professional equipment. By incorporating Roland’s revolutionary RSS (Roland Sound Space) technology – previously exclusive to units costing over $13,000 – Boss created a processor that didn’t just compete with established budget units, but challenged the sound quality and capabilities of processors costing several times more.
The Dawn of Accessible 3D Audio: RSS Technology Revolution
The SX700’s most revolutionary feature was its complete implementation of Roland’s RSS (Roland Sound Space) technology, a sophisticated 3D audio processing system that had previously been the exclusive domain of Roland’s highest-end professional units. This wasn’t a simplified version or subset of RSS – it was the full system, capable of positioning sounds in a complete 360-degree sphere around the listener with unprecedented precision and realism.
RSS operated on four distinct modes, each offering unique spatial processing capabilities:
3D Panner Mode provided real-time control over sound placement in three-dimensional space, allowing engineers to position individual sounds with precision control over azimuth (left-right positioning), elevation (up-down movement), and distance (near-far placement). This mode essentially turned the SX700 into a sophisticated surround sound processor, years before surround became mainstream in project studios.
Single 3D Mode focused RSS processing on creating a single, precisely positioned sound source within the 3D field. This proved invaluable for lead vocals, solo instruments, or any element requiring specific spatial placement within a mix. The mode allowed for smooth automated movement of sounds through 3D space, creating effects impossible with traditional panning.
Dual 3D Mode simultaneously processed two independent sound sources, each with complete 3D positioning control. This capability proved particularly valuable in electronic music production, where complex rhythmic elements could be positioned and moved independently through space, creating intricate spatial patterns that enhanced the rhythmic structure of compositions.
Quad 3D Mode extended the processing to four independent sources, effectively turning the SX700 into a sophisticated quadraphonic processor. This mode found favor among ambient and experimental musicians who used it to create immersive soundscapes that enveloped listeners in precisely controlled spatial environments.
The RSS technology incorporated sophisticated head-related transfer function (HRTF) processing, which accounted for the way human ears and brain perceive spatial audio cues. This wasn’t simple delay-and-filter processing – it was psychoacoustically informed spatial processing that created convincing 3D placement even when monitoring on standard stereo speakers.
Sound on Sound’s reviewer noted that “RSS alone is worth £419” – nearly the unit’s entire retail price of £450. This observation highlighted the extraordinary value proposition the SX700 represented, essentially giving users a professional 3D audio processor as a free bonus alongside a comprehensive multi-effects unit.
Professional-Grade Audio Quality That Defied Price Expectations
The SX700’s technical specifications read like those of processors costing thousands more. The unit featured 18-bit analog-to-digital and digital-to-analog conversion with 44.1kHz sampling frequency, delivering a remarkable 95dB signal-to-noise ratio (105dB in bypass mode). These specifications were genuinely professional-grade, matching or exceeding many established studio processors of the era.
The audio path was designed with uncompromising quality in mind:
The input stage operated at true +4dBm professional levels, unusual for budget processors which typically operated at -10dBV consumer levels. This professional signal handling meant the SX700 could integrate seamlessly into professional studio environments without level matching issues or signal degradation. A rear-panel switch also provided -20dBv operation for integration with consumer equipment, demonstrating Boss’s attention to practical studio needs.
The frequency response of 12Hz-20kHz with minimal phase shift earned widespread praise from professional reviewers and users. Unlike many budget processors that exhibited obvious coloration or frequency response irregularities, the SX700 maintained transparent, uncolored audio quality that preserved the integrity of source material while adding desired effects.
Sound on Sound’s comprehensive review declared it “one of the sweetest-sounding performers at any price,” noting that in blind listening tests, the SX700’s audio quality matched Pro Tools TDM plug-ins while significantly outperforming processors costing two to three times more. This wasn’t hyperbole – the SX700 genuinely delivered professional-grade audio quality that challenged assumptions about what budget processors could achieve.
The unit’s total harmonic distortion specifications of less than 0.01% ensured that even heavily processed signals maintained clarity and definition. This low distortion, combined with the high signal-to-noise ratio, meant that the SX700 could handle complex effect chains without introducing audible artifacts or noise buildup – a common problem with budget processors of the era.
Comprehensive Effects Architecture: Five-Engine Processing Power
The SX700 employed a sophisticated five-effector architecture that set it apart from simpler budget processors. This design allowed up to five simultaneous effects from different categories: EQ, Modulation, Delay, Reverb, and RSS. While the routing was fixed (users couldn’t rearrange the order), the combination provided exceptional processing power and flexibility within its structured approach.
Equalization Section: Surgical Precision
The always-available 3-band parametric EQ provided ±12dB of cut and boost across three fully parametric bands. Each band offered complete control over frequency, bandwidth (Q), and gain, allowing for precise tonal shaping that could correct problematic frequencies or enhance desired characteristics. The EQ maintained musical quality even with extreme settings, avoiding the harsh digital artifacts common in budget processors.
The EQ section’s transparency earned particular praise from users who found it suitable for both corrective and creative applications. Unlike fixed-frequency graphic EQs common in budget processors, the parametric design allowed for surgical precision when addressing specific frequency issues or creating dramatic tonal effects.
Modulation Effects: Ten Sophisticated Algorithms
The modulation section offered ten distinct effect types, each with multiple parameters for deep customization:
Chorus algorithms included standard, multi-voice, and ensemble modes, each providing lush, dimensional effects without the metallic artifacts common in budget chorus processors. The algorithms maintained stereo imaging integrity while adding richness and movement to sources.
Phaser processing delivered classic sweeping effects with selectable stage counts and feedback amounts. The phaser algorithms were noted for their smooth, musical character and absence of digital artifacts, making them suitable for both subtle movement and dramatic special effects.
Flanger effects provided everything from subtle doubling to extreme jet-plane sweeps, with comprehensive control over delay time, feedback, and modulation depth. The flanger maintained coherent stereo imaging while creating dramatic spatial effects.
Pitch-shifting capabilities included both chromatic and smooth pitch-bend modes, with tracking quality that remained stable across a wide range of source material. The pitch-shifting proved particularly valuable for creative effects and corrective applications.
Rotary speaker simulation captured the complex modulation characteristics of Leslie speakers, providing convincing Hammond organ effects and creative rotary processing for other sources. The algorithm included separate rotor and horn simulation with independent speed controls.
Delay Section: The Crown Jewel
The delay section represented perhaps the SX700’s greatest strength, offering seven distinct delay types with maximum delay times of 1400ms and comprehensive MIDI synchronization capabilities. Professional users consistently cited the delay section as exceptional, matching the quality of dedicated delay units costing significantly more.
Single delays provided pristine repeat quality with minimal coloration, making them suitable for both subtle doubling and obvious echo effects. The high-quality interpolation algorithms ensured smooth parameter changes without zipper noise or artifacts.
Multi-tap delays offered up to four independent delay taps, each with separate level, pan, and feedback controls. This capability allowed for complex rhythmic patterns and spatial effects that could transform simple source material into intricate sonic textures.
Quad delays provided four independent stereo delay lines, effectively creating a sophisticated delay matrix that could generate everything from simple stereo delays to complex spatial patterns that moved sounds through the stereo field in intricate patterns.
Reverse delays created ethereal, backwards effects that could be used for dramatic builds, special effects, or creative sound design applications. The reverse algorithms maintained high audio quality while creating convincing backwards effects.
The MIDI tempo synchronization proved revolutionary for electronic music producers, allowing delays to lock precisely to sequencer tempos with mathematical accuracy. This capability transformed the SX700 into an essential tool for dance music production, where rhythmic precision was paramount.
Reverb Algorithms: Nine Spatial Environments
The reverb section offered nine distinct algorithms designed to simulate various acoustic spaces and create artificial reverberant environments:
Room simulations included small, medium, and large room models, each capturing the intimate character of different sized spaces. The algorithms maintained clarity while adding appropriate spatial character, making them suitable for both natural and creative applications.
Hall reverbs provided the grandeur of large concert halls with impressive decay times up to 32 seconds. The hall algorithms captured the complexity of large spaces while maintaining definition and preventing muddiness common in budget reverb processors.
Plate reverb simulation captured the smooth, dense character of classic EMT plate reverbs, providing the familiar sound that had defined professional recording for decades. The plate algorithm proved particularly effective on vocals and percussion.
Special reverbs included gated, reverse, and modulated versions that could create dramatic special effects while maintaining the underlying quality of the core reverb algorithms.

The 1U rackmount chassis featured robust steel construction with proper electromagnetic shielding, ensuring reliable operation in demanding studio environments. The unit’s weight and build quality suggested professional-grade components throughout the signal path.
The front panel interface balanced functionality with clarity:
The 2×16 character LCD display provided clear, detailed information about current settings, effect parameters, and MIDI status. The display remained readable under various lighting conditions and provided sufficient information for effective programming without requiring constant manual reference.
Navigation employed a logical hierarchy with dedicated buttons for major functions and a velocity-sensitive data entry wheel that provided precise parameter control. The wheel’s velocity sensitivity allowed for both fine adjustments and rapid parameter sweeps, adapting to user needs in real-time.
Illuminated buttons provided clear status indication for all major functions, with appropriate brightness levels that remained visible without being distracting in darkened control rooms. The button layout followed logical groupings that minimized learning curve and supported efficient operation.
The rear panel provided comprehensive connectivity with stereo unbalanced 1/4″ inputs and outputs supporting both +4dBm professional and -20dBv consumer operation via rear-panel switching. MIDI In, Out, and Thru connections ensured complete integration with MIDI-based studios, while comprehensive MIDI implementation supported System Exclusive bulk dumps, real-time parameter control, and tempo synchronization.
Design Limitations and Professional Concerns
Despite its many strengths, the SX700 included several design decisions that drew criticism from professional users:
The external power supply (“wall wart”) was widely considered inappropriate for professional studio use. External supplies were associated with consumer equipment and presented practical problems in rack installations where AC outlets might be located far from equipment racks. Professional users expected internal power supplies with IEC connectors for reliable, professional installation.
The absence of digital I/O connections limited integration with emerging digital audio workstations and digital mixing consoles. By 1996, S/PDIF and AES/EBU digital connections were becoming standard on professional equipment, and their absence made the SX700 feel somewhat dated in advanced digital studios.
The fixed effect routing prevented users from reordering the processing chain, limiting creative flexibility compared to more expensive processors that offered configurable routing matrices. While the chosen order (EQ → Modulation → Delay → Reverb → RSS) worked well for most applications, some creative uses would have benefited from alternative routing options.
The lack of dynamics processing meant the SX700 couldn’t function as a complete channel strip, requiring separate compressors, limiters, or gates for applications requiring dynamics control. This limitation was notable given the unit’s otherwise comprehensive feature set.
Market Context and Competitive Landscape
The SX700 launched into a highly competitive effects processor market dominated by established players with well-defined market positions. Yamaha’s SPX90 series had defined the budget professional category with reliable operation and distinctive algorithms, while Alesis MidiVerb and QuadraVerb series offered comprehensive processing at aggressive price points. Lexicon’s budget processors provided the company’s renowned reverb quality in affordable packages, and Roland’s own SE-50 and SE-70 had established strong followings for their musical, colorful character.
The SX700’s $645 USD pricing positioned it strategically above basic budget processors while remaining accessible to project studios and serious home recordists. This pricing reflected genuine professional capabilities while maintaining affordability – a positioning that proved crucial to its market success.
The unit represented Boss’s strategic shift from character-driven to transparent processing. The SE-50 and SE-70 had been praised for their “fat, colorful character” but criticized for obvious sonic fingerprints that made them unsuitable for transparent, professional applications. The SX700 marked Boss’s entry into the transparent, professional processor market while maintaining the musical quality that had defined earlier Boss processors.

Technical Deep Dive: The RSS Implementation
The SX700’s RSS implementation represented a sophisticated approach to 3D audio processing that went far beyond simple delay-and-filter techniques. Understanding its technical approach reveals why it remained unique even decades later.
Head-Related Transfer Function (HRTF) Processing formed the core of RSS technology. Roland had researched human spatial hearing perception extensively, creating mathematical models that described how the human ear and brain interpret spatial audio cues. These models were implemented as complex filter networks that could convincingly simulate the acoustic characteristics of sound arriving from specific 3D locations.
The processing algorithms accounted for multiple spatial cues:
Interaural Time Differences (ITD) – the slight timing differences between sounds arriving at left and right ears – were accurately modeled to provide left-right positioning cues. The RSS system could simulate these timing differences with microsecond precision, creating convincing left-right placement.
Interaural Level Differences (ILD) – the amplitude differences caused by head shadowing effects – were modeled to enhance left-right positioning and provide distance cues. The system could simulate how high frequencies are absorbed differently by the head depending on source position.
Pinnae filtering effects – the complex filtering caused by the outer ear’s shape – were modeled to provide front-back and elevation cues. This was perhaps the most sophisticated aspect of RSS processing, as it addressed the most difficult aspect of spatial audio: distinguishing between sounds in front versus behind the listener.
Distance simulation employed multiple techniques including early reflection patterns, frequency response changes, and dynamic range modifications to create convincing depth perception. Distant sounds were processed to include appropriate frequency rolloff and reduced dynamic range that matched human perception of distant sources.
The real-time processing requirements were substantial for 1996 technology. The RSS algorithms required significant computational power to maintain audio quality while providing real-time parameter control. Boss’s implementation achieved this through custom DSP architecture that balanced processing power with cost considerations.
The Delay Section: Engineering Excellence
The SX700’s delay section represented state-of-the-art delay processing that competed with dedicated delay units costing significantly more. Understanding its technical implementation reveals why it earned such consistent praise.
High-Quality Interpolation Algorithms ensured smooth parameter changes without zipper noise or artifacts. When delay times were modified in real-time, the system employed sophisticated interpolation that maintained audio quality while providing smooth transitions between settings.
The 1400ms maximum delay time was substantial for 1996, when memory was expensive and most budget processors offered significantly shorter delay times. This generous delay allocation allowed for musical delays across a wide range of tempos and musical styles.
MIDI Tempo Synchronization employed mathematical precision that locked delays to MIDI clock with sample-accurate timing. This capability proved revolutionary for electronic music producers who required precise rhythmic alignment between delays and sequenced material.
Multiple Delay Algorithms each addressed different musical requirements:
Single delays provided pristine repeat quality with comprehensive control over feedback, tone, and level. The algorithms maintained stereo imaging while providing clear, musical repeats.
Multi-tap delays offered complex rhythmic patterns with independent control over each tap’s timing, level, and pan position. This capability allowed for intricate polyrhythmic effects that could transform simple source material.
Quad delays created sophisticated stereo delay matrices where sounds could bounce between left and right channels in complex patterns while maintaining clarity and definition.
The delay memory management employed efficient algorithms that maximized available delay time while maintaining audio quality. The system could dynamically allocate memory based on selected algorithms, ensuring optimal performance for each delay type.
MIDI Implementation: Professional Integration
The SX700’s MIDI implementation reflected professional requirements for studio integration and automation. The comprehensive MIDI specification supported real-time control, program changes, and system exclusive bulk dumps that enabled complete automation and integration with MIDI-based studios.
Real-Time Parameter Control via MIDI continuous controllers allowed external sequencers, MIDI controllers, or automation systems to control virtually every effect parameter in real-time. This capability proved essential for electronic music production where effects automation was integral to compositions.
Program Change Support provided instant access to all 256 presets via MIDI, enabling automated preset changes synchronized with musical arrangements. The rapid preset changes allowed for dynamic effect switching that enhanced live performances and complex studio productions.
System Exclusive (SysEx) Implementation supported complete parameter dumps, enabling users to backup and restore all settings via MIDI. This capability proved valuable for archiving sessions and sharing settings between multiple SX700 units.
MIDI Clock Synchronization for delay effects provided sample-accurate timing that locked delay repeats to MIDI tempo. This synchronization worked across tempo changes and song position pointer jumps, maintaining musical alignment under all conditions.
Multi-Channel MIDI Support allowed the SX700 to respond to different MIDI channels for various parameters, enabling complex automation scenarios where different controllers could simultaneously control different effect parameters.
Sound Design Applications and Creative Techniques
The SX700’s unique capabilities enabled creative techniques that were impossible with conventional processors, leading to its adoption for sound design and experimental music applications.
