Praga

Praga is a voltage controlled four channer stereo mixer. Each channel features:

. manual and voltage control over volume and panning,
. indivual VCA outs,
. 2 auxilliary sends,
. mode switch for envelope or LFO operation (attenuators change function, being and offset, or CV amount controls, respectively),
. channel muting,
. 5-bar signal level indicator

The module is build around high quality VCA chips from THAT Corp, as well as low noise opamps. It offers clickless muting and equal loudness panning. The distinct feature is that voltage control is dynamically compressed should it yield clipping when pushed too hard. Also, in both modes the attenuators offer full closing of the corresponding channel, regardless of being controlled by the CV, or not. The VCAs fully open (0dB gain) at CV=8V in Env mode and CV=5V in LFO mode. All the input and output signal levels are Eurorack levels.

Multiple Praga units can be chained thanks to dedicated headers on the back. The mixed stereo sum of each unit in the chain is added to the mixing bus of all units downstream.

A dedicated Hrad expander will offer master volume control, gate inputs for channels muting/unmuting, headphone amplifier, and voltage control over aux sends.
