Modcan Dual Delay 73B

"The Dual Delay represents the next step in delay based effects from Modcan. This is not just a dual version of the 59B. We completely reworked both the hardware and firmware model to add significant features and enhancements to improve upon the popular 59B design.

The most obviously apparent change was to make it a Dual with independent controls for each channel. We also added selectable modes for delay type. Choices are Re-sampling (pitch shifting effect when altering delay time) and a "Clean" mode for standard Digital Delay effects without pitch shifting.

Low noise design using 48kHz sample rate, 32bit DSP processing and 16bit I/O.

Other features include 0Hz-21K continuously variable 4 Pole Lowpass filter in the delay feedback path for "Analog BBD/Tape Delay" emulation. The filter has full range self oscillating resonance with voltage control of resonance amount and filter cutoff.

Input signals can be routed as two mono delays or stereo or as a dual Tap delay with delays in series internally.

Each channel can be either in clean or resample modes and can also be patched in series and parallel for external feedback path.

Delay time can be set by panel control knob, CV, external sync pulse and tap tempo buttons. Also sync division is available to divide the pulse clock. Each delay has 3 ranges

Resample Delay Ranges:
Lo: 0.01s - 0.06s
Mid: 0.06s - 0.5s
Hi: 0.5s - 4s

Clean Delay Ranges:
Lo: 0.0006 - 0.02s
Mid: 0.02s - 0.91s
Hi: 0.91s - 5.46s

All the functions (except input level) that are controlled by panel knobs have matching CV inputs allowing for a wide range of flexible control modulation.

The module uses very low current requiring only 40mA for operation and will work with any power supply between 8 and 15V. Less current than many simple analogue modules.
