The DeltaLab DL-2 ACOUSTICOMPUTER was introduced as a compact, all-electronic digital delay and effects processor built to meet the increasing demands of modern recording and live performance. Designed and manufactured by DeltaLab, the DL-2 builds on the company’s established reputation from its earlier delay systems, offering a combination of delay processing, modulation, and reverberation within a single rackmount unit. It was positioned as a complete solution for musicians and engineers requiring clean signal paths, wide bandwidth, and a high degree of control over time-based effects.
At its core, the DeltaLab DL-2 ACOUSTICOMPUTER is a true stereo, dual-channel processor, providing two independent delay channels that can operate across a wide range of delay times. Short delays extend down to 0.25 ms, allowing for flanging and comb filtering effects, while longer delays reach up to 252 ms in serial mode, enabling more complex echo and spatial treatments. This range allows the DeltaLab DL-2 ACOUSTICOMPUTER to cover everything from subtle doubling and chorus effects through to pronounced slapback and multi-tap echo applications.
The DeltaLab DL-2 ACOUSTICOMPUTER incorporates 16 reverberation programmes, designed to provide dense echo structures and extended spatial textures. These programmes are displayed using binary weighted LED indicators, offering clear visual feedback for selection and operation. In addition to standard delay and reverb functions, the unit includes both positive and negative feedback paths, allowing for more advanced manipulation of reverb and flanging characteristics.
A key feature of the DeltaLab DL-2 ACOUSTICOMPUTER is its voltage controlled oscillator system, which provides sinusoidal modulation across a 4:1 frequency range. This enables a wide variety of modulation-based effects including vibrato, tremolo, and pitch shifting. The variable time base and VCO depth controls allow precise adjustment of modulation intensity and speed, giving users the ability to create both subtle movement and more pronounced modulation effects.
The sustain function within the DeltaLab DL-2 ACOUSTICOMPUTER allows signals to be repeated indefinitely without degradation, with a sample mode that updates the stored signal at a rate determined by the VCO. This provides additional creative control for looping-style effects and evolving textures, particularly useful in both experimental studio work and live performance contexts.
Stereo imaging controls are available on both input and output stages, enabling users to extract ambient information or shift signals across the stereo field. This functionality allows for enhanced spatial manipulation, supporting applications such as widening, positioning, and depth enhancement within a mix. The inclusion of feedback and equalisation circuitry further expands the tonal shaping capabilities of the unit.
For live applications, the DeltaLab DL-2 ACOUSTICOMPUTER includes a footswitch bypass control, allowing performers to engage or disengage effects in real time. External VCO inputs provide additional modulation control, enabling integration with other equipment for more complex signal processing setups.
The unit also supports external memory expansion, significantly extending available delay times without compromising signal quality. Each additional module provides up to two seconds of delay, with total delay length limited only by the number of modules installed. This capability addressed one of the primary limitations of early digital delay systems by maintaining bandwidth and dynamic range even at extended delay lengths.
Designed for both studio engineers and performing musicians, the DeltaLab DL-2 ACOUSTICOMPUTER combines high bandwidth performance, with a frequency response extending to 15 kHz, and a dynamic range exceeding 90 dB. The unit maintains low distortion characteristics and delivers consistent signal integrity across all delay lengths, ensuring reliable operation in demanding audio environments.
The DeltaLab DL-2 ACOUSTICOMPUTER represents a versatile and integrated approach to digital delay and effects processing, consolidating multiple time-based and modulation effects into a single, roadworthy unit suitable for professional use.
