Product description

Concept1 is an integrated stereo amplifier supplied by Apart Audio (Biamp). Two-zone Concept1 can work both in one zone as a stereo system and in two zones with individual or joint volume control as a mono system. The RMS power of the device is equal to 60 watts at 8 ohms and 80 watts at 4 ohms per one channel.

The rear panel of the Concept1 amplifier is equipped with four unbalanced line inputs (8 x RCA), a balanced microphone input in the form of a Euroblock terminal, one pre-amp output (2 x RCA) and one line (2 x RCA) with a constant signal level. The user also has access to two outputs for the connection of right/left channel (Euroblock), the RS232 connector (which offers control options) and the IR port.

The front panel is equipped with an additional D line input, thanks to which it is possible to connect e.g. external audio device. The panel also contains four buttons for selecting the appropriate source (A-D), a selection button and a knob for adjusting the volume, treble, and bass.

The dimensions of the Apart Audio Concept1 amplifier (especially the height of 2U) allow the equipment to be installed in a 19-inch rack. SQM Multimedia Support recommends this amplifier.
