Preamplifier & Volume/Tone Control

7x AOP NE5532 - 5.1 / 2.0

Préamplificateur et contrôle de volume 5.1 / 2.0

A complete preamplifier module

This really complete preamplifier module has the particularity of offering a choice of connecting a 2.0 system or a 5.1 system, via a remote module (supplied, with its connection cable). So whether you have a classic system or a home theater system, this preamplifier will blend perfectly with your hardware.

7x AOP NE5532 and quality components

This tone controlled preamplifier is based on a series of 7 operational amplifier TI NE5532, one per channel plus another for the filter, combining excellent DC and AC characteristics. They offer very low noise and distortion ensuring a clean signal.

Also on the board are 2x1000µF Ercon Japanese capacitors for the main filter or 1A rectifier bridges to obtain a stable continuous signal. On the resistors side, these offer an accuracy of +-1% allowing to obtain a very good Signal/Noise Ratio. There are also Siemens 1µF capacitors from Germany, ensuring soft highs and deep bass.

Accurate volume/tone control

This module integrates no less than 6 potentiometers allowing you to precisely adjust each element of your system. So you can change the sound of your surround speakers, headphones, center speaker and subwoofer separately. It is also possible to adjust the low frequencies in order to obtain a more homogeneous, more coherent reproduction. Finally, once these adjustments have been made, a potentiometer is used to adjust the overall volume for greater simplicity.

There is also a small switch on the module to invert the subwoofer phase to match the phase rotation of your speakers. So your speakers and subwoofer will work in perfect harmony.
