Source & Volume module PGA2311

This extremely complete module combines a volume control & source selection function. It is divided into two cards: power board & connectors / screen board & controls.

Each PCB is connected by a ribbon cable (supplied) thus allowing easy integration even in short spaces and small housings.The same goes for the remote rotary encoder (also supplied), which can be installed in the location of your choice without causing any particular integration constraint.

The module is equipped with its own regulated linear power supply. Just connect it to a dual 9V or dual 12V toroidal transformer and the module is already operational.

The source selector has five stereo RCA inputs. The passage from one source to another works with relays to avoid bumps and protect sensitive devices.

The PCB dedicated to the display is also equipped with an infrared receiver. it is therefore possible to control all the module functions remotely using a remote control.

Volume control

The module has a volume control function based on a PGA2311 chip. This component provides analog control on each channel individually, ensuring an extremely low crosstalk level of -126dBFs.

The volume range allows adjustment from -95.5dB up to 31.5dB in increments of 0.5dB, a level of precision far beyond a traditional potentiometer.

The volume control is intelligent, that is to say that the PGA2311 chip will automatically detect if it is best to simply increase the resistance opposing the signal or on the contrary if it is best to preamplify the signal in order to obtain a very clean signal in terms of distortion. It is then possible to use this module both upstream of an external preamplifier or directly connected to a power amplifier.

Each channel has its own gain parameter which can be adjusted independently. Moreover the module keep our settings in memory even when powered down.


LCD display with I/R receiver

The module comes with an LCD screen 2x16 already configured with pre-soldered connectors and ready logic circuit. No programming knowledge is required to make the display work.

The display shows in real-time the volume level and the current source.

All the connections necessary for powering & interfacing ithe display are provided.

The PCB of the display also loads the infrared receiver for intuitive use of the remote control.


In addition to all these features, the card is equipped with its own bridge rectifier, filter capacitor and voltage regulator. It's only missing a toroidal transformer to enjoy a clean power that will allow the PGA2311 chip to operate in the best conditions.

Power supply range is from 2x9V to 2x12V.
