External DC Supply Input OFF 10. Input 2 - Unbalanced AUX Connections for an external 24V DC supply to power the amplifier. Provides a high-impedance input through a set of stereo combining RCA jacks. This input is muted by Input 1 when muting is enabled. 7. Speaker Outputs 11.
Output Connections Speaker Outputs The amplifier’s 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).
Operation Level Controls The amplifier provides separate input level controls on the unit front panel for rear inputs 1 and 2. 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 unit’s frequency response. LINE/MIC Selector Switch Input 1 provides an electronically-balanced input with selectable gain suitable for microphone and LINE/TEL level signals.
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. Likewise do not slide books or papers under the amp which will reduce the intake area for the cooling air.
