DESCRIPTION

ADDAC712 is a dual channel discrete gain staging ampli-

fier, based on a famous discrete preamp board from the

70’s used in some legendary equipment.

What caught our attention was the character of it’s

clipping and resulting saturation/distortion.

The module can be used with modular signals to add a

distortion/fuzz character or as a preamp for an external

source such as a line source, keyboard, guitar...

It’s also a great side companion for our ADDAC711

Balanced Inputs.

At the top an On/Off [BYPASS] switch routes the signal

into the Effect (Up: Active) or to the bottom output gain

stage (Down: Bypassed).

The ammount of amplification is set by the [GAIN]

control, the maximum ammount of amplification can be

set by the user using the [MAX GAIN] trimmer.

Up to ±5.5v the incoming signal will keep it’s integrity,

beyond this point saturation will start to increase.

At aprox. ±6v a hard clipping will start to occur, this

clipping also has a particular quality that at extreme

levels it drifts the audio 0v bias reference, moving it

upwards which results are similar to a Gate effect.

In the middle, an p2-x2 opamp based output gain stage

with a clipping led, which monitors the clipping at the

output, and an [OUTPUT] control to set the output

volume.

Having the top and middle gain stages provides flexibili-

ty allowing the user to completelly distort the signal on

the top stage and tame it’s output level with the second

stage.

At the bottom, Input and Output for both channels (Left

input is normalled into Right input).

This module will also be available as a full DIY kit..
