Adastra A4 Dual Stereo Amplifier 4 x 200w

The Adastra A4 4 Channel Stereo Amplifier is a great choice for small Cafes, Offices, Restaurants & shops looking to install a background music sound system or foreground system. The amplifier offers 2 zones across 4 channels each with independent volume adjustment, allowing for complete control across the whole system.

4x channels at a minimum of 4 ohms allow for a large variety of speakers to be connected. Each channel has individual volume control and an LED signal indicator.

Where the Adastra A4 shines is its zonal capabilities. Channel 1/2 & 3/4 are split into groups with further control. Each pair of channels has EQ control, and source selection meaning different audio sources can be played on each pair of channels.

There are 3x stereo inputs, 2x RCA and an L & R 1/4" (6.35mm) Jack, and 2x Mono 1/4" (6.35mm) Jack inputs, indicated as Mic 1 and Mic 2.

There is also a stereo RCA line out, which can be used to expand the system as this will allow you to send the input source to another amplifier, or compatible active sub.

An inbuilt media player section offers playback of mp3 audio tracks from USB drive or SD card and also has a Bluetooth receiver and FM radio tuner.
