APart has introduced the Concept 1, a competitively priced integrated amplifier for professional use. It can operate with one stereo zone, two volume-linked zones, or two individual-volume zones. The unit also offers versatile user and installer settings, RS-232 control, gain-adjustable line-inputs, and a MIC-input for paging.
Apart from standard user controls, there
are expert settings that can only be
adjusted by the installer. These include maximum
volume per zone, the microphone levels and
pre-set gain per source.
The units can
operate in a stand-alone mode, or be
remotely controlled via IR or RS-232 and
feature four stereo, gain-adjustable line-inputs as well
as an integrated switchable highpass filter for subwoofer use.
