With 16 built-in reverb and multi-effects, the Coolaudio V1000 Digital Multi-Effects DSP delivers outstanding audio performance in a rapid time-to-market solution at a very affordable price. Since the V1000 incorporates its own RAM and on-board effects, a complete reverb system can be designed with only the V1000, a low-cost ADC and DAC, and a simple 4-bit controller such as a rotary encoder etc. Package: SOIC-16/300.

The Coolaudio V3102 is a universal CMOS LSI to generate a two-phase clock signal of low output impedance, perfectly suitable to drive BBDs up to 4096 stages, such as V3207, V3208, V3205, etc. Package: DIL-8.

Drop-in replacement for the obsolete MN3205 delay chip and a functional replacement for the MN3005. The Coolaudio V3205SD is a 4096-stage low-noise, low-voltage BBD analog delay line that provides analog signal delays of up to 204.8 ms and is particularly suitable for the generation of sound effects (reverb, echo, phaser, flanger, etc.) in audio equipment such as guitar effects pedals, sound amplifiers, karaoke machines, etc. Package: Special DIL-8.

The Coolaudio V4220M is a high-performance 24-bit audio codec providing stereo AD and DA converters using the latest conversion technology. It operates from a single +5 V power supply and features very low power consumption and selectable de-emphasis filter for 32, 44.1 and 48 kHz sample rates. Applications include digital effect processors, stomp boxes, etc. It perfectly complements the Coolaudio V1000 DSP and provides an ultra-low cost FX solution. Package: SSOP-28.

The Coolaudio V571D is a cost-effective dual-gain circuit which either channel may be used as a dynamic range compressor or expander. Each channel has a full-wave rectifier to detect the average value of the signal, temperature-compensated variable gain cell and an operational amplifier. The V571 is well suited for any compander systems in communications and noise reduction systems. Package: DIL-16.
