AUDIOPHONICS PRE-01 PGA2310 Preamplifier Volume Control Input Selector Bluetooth 5.0

An excellent volume controller

As its name suggests, the device incorporates a volume control based on a PGA2310 TI chip offering very good audio performance. This allows a very precise volume adjustment from -90 to 0dB. This chip allows to obtain a very low distortion of 0.004%, a dynamic range of 120B, a THD+N of 0.0004% at 1kHz and a crosstalk of -126dBFS.

Connectic

The Audiophonics PGA2310 offers both classic connectivity with 4x stereo RCA inputs but adds Bluetooth in version 5.0, thanks to its JL AC1820AP chip. It is thus possible to stream your music remotely from a device with this connectivity such as a smartphone or tablet for example. Bluetooth version 5.0 ensures excellent stability and transmission speed for quality listening. A Bluetooth antenna is included to improve transmission.

The output side is simply one stereo RCA to connect the PGA2310 to an amplifier. Finally, power is supplied directly via the IEC cable (not provided) from a mains socket. The unit's power supply circuit incorporates efficient multi-channel regulation to significantly reduce noise.

Power circuit

The quality of the power supply being decisive in the quality of the sound reproduction of an audio system, the Audiophonics PGA2310 benefits from a neat circuit. Thus, it integrates an efficient multi-cana regulation allowing to limit considerably the noise as well as an EMI / RFI filter allowing to filter the interferences which could generate noise.

Simple but effective design

In terms of design and ergonomics, the Audiophonics PGA2310 is simple and efficient. The components are integrated in a robust brushed aluminium housing with the most beautiful effect. A 51 x 20mm front panel screen displays both the active source from the 4 available and the sound volume, the latter up to an absolute value of 100. The white LED display provides excellent readability for easy adjustments. The unit also comes with an infrared remote control, allowing access to all settings, including volume adjustment, mute mode and source selection.

Meilleur
Rachat du même modèle, sauf que le nouveau est bien plus performant, il y une nette préamplification que ce modèle n'avait pas vraiment avant, et la qualité du son est bien meilleure.
Je m'en sers pour contrôler le volume sur un signal ligne venant de mon PC avant l'entrée dans la console de mixage (pour avoir accès au volume à distance via la télécommande depuis la mezzanine).
Très satisfait.
