Module control volume and source selector


This module combines a volume control & source selection function. It is divided into two cards: a board dedicated to connectors and power supply & board dedicated to screen and controls. It has a OLED display which indicated volume and source status.

Each PCB is connected via a XH cable (provided) thus allowing easy integration even hard-to-access environments. Same thing is true for the rotary encoder (also supplied), which can be set anywhere thanks to a long wire cable.

The module is equipped with its own linear regulated power supply. Simply connect it to a toroidal transformer ranging from 2x12VAC to 2x16VAC and the module is already operational.

The source selector has three input stereo RCA. The transition from one source to another works with relay to prevent thumps and protect sensitive devices.

PCB dedicated to the display is also equipped with an infrared receiver. It is therefore possible to remotely control all functions of the module using a remote control (also provided).

Volume Control

Volume control PGA2310

The module embeds a volume control function based on a PGA2310 chip. This component provides an analog control on each channel individually, ensuring extremely low crosstalk level of -126dBFs.

The volume range can range from -95.5dB to 31.5dB with 0.5dB increments. This level of accuracy is well beyond a traditional potentiometer.

The volume control is intelligent, that is to say the PGA2310 chip will automatically detect whether it should simply increase  the resistance opposing the signal or whether it should instead go on pre-amplify mode to obtain the best restitution in terms of distortion. It is therefore possible to use this module both upstream of an external preamplifier or directly to a power amplifier.

Using the remote control, it is even possible to adjust the stereo balance (individually controlling the right / left volume on entry into use).


OLED display with I/R receiver

The module comes with an OLED 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.

linear regulated power supply


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 PGA2310 chip to operate in the best conditions.

The power range extends from 2x12VAC to 2x16VAC.
