This buffer has been designed to support Hypex 4 channel DSA254 NCOREX amplifier.

This buffer has fixed high gain which can be changed for each of the channels by removing resistors R132/CH1, R133/CH2, R134/CH3, R135/CH4:

High gain – 26.5dB
Low gain – 19.5dB.

If more gain is needed, two channels (CH1/CH2 or CH3/CH4) coulf be used in BTL mode producing 32.5dB.

The module uses gold plated DIP-8 IC Socket ROHS which allow multiple choices of dual channel opamps. Discrete opamp are not supported.

This model has three year warranty and free shipment.
