The LR-100 has an AUXILIARY input that allows for greater functionality of the unit for a variety of applications. The AUXILIARY input consists of a balanced input, combination connector (female XLR and 1/4 in) and two unbalanced phono connectors. All of these inputs are actively mixed together. Thus, any combination of input sources can be used. Input level is adjusted via the front panel trim pot labeled AUX LEVEL ADJUST. Adjust this level to fit the needs of your installation ensuring the last red LED on the VU meter is not illuminated (indicating peak audio).

Speaker Connection

The LR-100 contains a 44-watt (31 watt RMS), 4-Ohm power amplifier.

i.The Speaker Selection switch determines what audio is directed to the power ampli- fier. With the switch in the OUTPUT position, the OUTPUT audio (same audio that is on the OUTPUT audio connectors) is directed to the power amplifier. With the switch in the AUX position, AUXILIARY input audio only is directed to the power amp. This allows you to use the power amplifier separate of the RECEIVER audio if desired.

Note: When the speaker switch is in the OUTPUT position and the MUTE control is enabled (indicated by the illumination of MUTE LED), the speaker output is also muted.

ii.Connection to the speaker is achieved through pins 1 and 2 on the detachable termi- nal block. Strip the speaker wires, rotate the screws on the terminal block counter- clockwise, insert the wires and then tighten the screw clockwise until the wire is secure in the connector block. You may connect any parallel, series combination of speakers that produces an impedance of 4-ohms or greater.
