Applications

Stereo Operation

The LION 2-1000 Amplifier can be used in the stereo mode as two separate 1000 watt units, each capable of driving loads down to 4 ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator LEDs, automatic limiter, fault protection circuitry, power amp, and speaker outputs. In the stereo mode, the signal smart switch must be set to the stereo position. One application of the stereo mode uses one channel of the amplifier for the left house speakers and the other channel for the right. The mixing board channels can be panned left or right according to the position of the instruments on the stage. This approach provides a more accurate reproduction of the live performance.

Mono Bridge Operation
The two internal power amplifiers (CHA and CHB) can be bridged together to form a single, higher powered amp. This is especially useful when using the amplifier to power a subwoofer. In the mono mode, the amplifier uses the Channel A input jacks and sensitivity control (Channel B’s are disabled).
When operation in this mode, each channel is independently protected. The signal smart switch must be set to the bridge position and the minimum speaker load impedance must be 4 ohms.

Patching two bridge mono mode system
Two bridge mono amplifiers can be patched together (operated in mono mode) with connecting signal cable between their input jacks. The signal smart switch must be set to the bridge position.
