Coolaudio V3207D 1024 Stage Analog Delay Line (DIL-8)

 Loading product data...
The Coolaudio V3207 (a replacement for the MN3207) is a low-noise analog delay line capable of delaying an analog signal up to 51.2msec. This delay line is commonly used to generate audio effects such as reverb, echo, phaser, etc. This BBD (Bucket-Brigade Device) has 1024 stages and requires a two-phase clock (see the Coolaudio V3102).

Selection Notes
The 300X series has the best S/N ratio for a given clock frequency and delay period because it's higher supply voltage gives it more headroom (dynamic range). If the system is running at 9V then the 300X series may not provide much advantage as the dynamic range is reduced. The 300X series is more expensive, but can provide significantly better S/N and is the only series that includes a 256 stage device (3009) for very short delay times. Note that the V3207 can achieve a shorter delay than the corresponding MN3007 because it supports a clock of 200kHz. So in general, if the system power supply is less than 10V or is price sensitive, the 320X series may be the best solution. If a high S/N ratio is desired or very short delay times then the 300X series may be preferred. Note the S/N ratio of any BBD may be improved by support circuitry such as a compander (V571 or similar).

This device is functionally compatible to the Panasonic MN3207.
