ACM120XL 120 Watt Mixer Amplifier Operating Manual
ACM120XL, 120 Watt Mixer Amplifier Product Description The ACM120XL is a 120 watt mixer amplifier designed for commercial installations. It features 8 microphone/line input channels and can be used for either low impedance (4 or 8 ohm) or 70v/100v line speaker systems. A host of unique features including multiple levels of muting, a VOX relay output and VCA master level control make the ACM120XL a very flexible amplifier.
Signal LED The green “Signal” LED located next to the On LED indicates that the ACM120XL is passing audio. The signal LED is a simple method to trouble-shoot installations especially in multi-amplifier projects. Rack Mounting The ACM120XL is supplied with rack ears attached to allow mounting within a standard 19” equipment rack. As is the case with almost all audio products, adequate ventilation and air flow is required.
VCA Control An external pot (500 ohm to 1K) can be connected to the ACM120XL for remote control of the master level. While a 1K pot can used, better results (smoother volume adjustment) can be obtained by using a 500 ohm pot. The external pot is governed by the master level of the amplifier allowing the installer to set the volume, then lock the amplifier in a rack leaving the user with just a master volume control that cannot go beyond the level set on the master (front panel) control.
Dual RCA Line/Auxiliary Inputs The ACM120XL includes 8 microphone and line (auxiliary) inputs. The line inputs are via dual RCA connectors per channel. Although the ACM120XL is a mono amplifier, dual RCA’s are provided to allow for easy connection to domestic or professional line sources. The line inputs are suitable for a wide range of products including tuners, cassette decks and CD players. As the output signal from line sources can vary immensely, four sensitivity settings are available per line input.
