Quest QTA ACC1 Mini 2 Channel Power Amplifier

The QTA ACC-1 is a high quality compact class D 2×20 watt highly efficient digital amplifier powered by a 24 volt power supply. It can be powered by its own 24V supply or alternatively, by a 24V DC "party line".

The QTA ACC-1 is perfect for the education, A/V installation and high end commercial market where compact high intelligibility speakers in small spaces or distributed environments are required. It is an ideal partner for the Quest M series wall and in wall speakers and because of the  low radiated heat of the amplifier, this unit may be installed within the ceiling or wall cavity or attached to the rear of a flat screen TV monitor.  Volume may be set at a fixed level or changed via a Projector remote control. When more power is required, bridge mode can be selected to deliver 40W RMS.
