Modes |
(1) Slide switch;
Selects stereo, summed, bridged, 70V, or 100V operation
- STEREO (LoZ): The input signal received on each channel is sent to its respective output for use in applications where left and right channel separation is required. The two GAIN controls are independently adjustable.
- SUM (LoZ): The input signals sent to a channel pair (1 + 2) are summed and sent to their respective individual outputs. The two GAIN controls are independently adjustable.
- BRIDGE (LoZ): The input signals sent to a channel pair (1 + 2) are summed and sent to a bridged output (1 + 2) for use in high-power applications. The GAIN 1 control adjusts the bridged 1 + 2 output.
- 70V (Hi-Z): The input signals sent to a channel pair (1 + 2) are summed and sent to a bridged output (1 + 2) for use in Hi-Z 70V applications. The GAIN 1 control adjusts the bridged1 + 2 output.
- 100V (Hi-Z): The input signals sent to a channel pair (1 + 2) are summed and sent to a bridged output (1 + 2) for use in Hi-Z 100V applications. The GAIN 1 control adjusts the bridged 1 + 2 output.
