MAD PROFESSOR DEEP BLUE DELAY

Description

The Deep Blue Delay is a natural-sounding digital/analog delay, with an analog direct signal path. The Deep Blue Delay has approximately the same bandwidth as classic tape echo units and can be used before an amplifier or in effect loops.There are no noise reduction circuits, which keeps the echo decay as natural as possible.The direct signal path is short and made with analog amplifiers without filtering.There is no distortion or tonal coloration as long as the input level is within the range below the maximum allowed.The echo signal has tuned filtering to allow extreme settings without interference.The delay is specially designed to work well even with distorted tones, as this is the most critical application, where delays often fail.The Deep Blue Delay contains the basic functions, Delay Time, Delay Level and Repeat, and is designed to work as an ambient delay; Like a vintage tape echo and repeat, it is specially designed to allow easy adjustment and a less critical setting of the delay time. Why digital? Isn't analog better for a solid-state solution?We chose digital construction to make it compact, stable, with reasonable delay times and virtually maintenance-free.A similar circuit in analog form would have been excessively more expensive to build. For the same performance, three to four of the best BBD chips, now only available as vintage parts, would have been needed and the pedal size would be about three times the current size.Controls:LEVEL: Sets the level of the delayed signal mixed with the direct guitar sound.DELAY: Controls the delay time from 25 ms to 450 ms.REPEAT: Controls the repetitions of the delay signal, rotated fully counter-clockwise gives one repetition and fully clockwise you get infinite feedback.Technical Specifications:Power supply: 9V 6F22 battery or power supply Current consumption at 9V: 32mAVoltage range: 8V-15VInput impedance: 180 kOhmOutput impedance: 10 kOhm Signal-to-noise ratio: 80 dBFully buffered bypass and circuit input to ground when in bypass
