These compact 1RU rack mount amplifiers are suitable for both stand alone PA system use, or as zone amplifiers in larger systems requiring local inputs. All models operate on 240V ac or 24V dc for battery backup operation.
All models include a choice of six source options on 2 inputs. Input one consists of a 3-pin XLR which can be set for either balanced mic level (3mV) or balanced line level (2V), adjusted via a rear mounted trimpot. A dual RCA is also provided on input one with adjustable sensitivity of either 100mV or 1V. Input two consists of three sets of dual RCA sockets on the rear panel and a 3.5mm jack on the front panel. Auxiliary source inputs are selected via the front panel switch. Input one can be DIP switch selectable to VOX mute input two. Phantom power is also provided on input one XLR. Volume level controls are provided on the front panel for inputs one and two.
The circuit includes protection features in case of output over voltage, over current and over temperature. All are self resetting once the fault condition is removed. Visual indication via front panel LEDs display amplifier status at all times.
