Output Connections Speaker Outputs The amplifierʼs speaker output terminal strip provides connections for 70V and 25V speaker systems, as well as low-impedance speakers loads of 4- or 8-ohm impedance. Connect one end of the speaker load to the COM terminal and the other side of the load to the terminal corresponding to the type of system being driven (transformer-coupled 70/25V speaker or low-impedance speakers without transformers).
Input Connections Balanced - TEL Input The TEL input is a transformer-balanced input. The telephone signal should be Dry Audio with no DC voltage between the signal lines. If the telephone has a DC voltage across it, a telephone interface adapter should be used to provide a compatible signal for this input.
Operation Level Controls The amplifier provides separate input level controls on the unit front panel for rear inputs 1 through 4. Turn knobs clockwise to increase, or counterclockwise to decrease levels. Bass & Treble Controls Bass and treble controls are located on the front of the unit to provide tailoring of the unitʼs frequency response.
Operation Media Player The Media Player can play MP3 or WMA files from either an SD card or a USB memory stick inserted into the player on the front panel of the amplifier. Pushbuttons on the front of the media player control operation functions and an LCD screen displays status information (see below).
Cooling Ventilation The amplifier is passively cooled so care must be taken to make cool air available to the amplifier. Do not operate this amplifier in environments that get hotter than 100 deg. F. If the amplifier is to be free standing, do not remove the feet on the amp since they provide a space on the bottom of the amp for cooling air intake.
