Instructions for Use：
1. The LSYSAQA7 output can only be connected to passive speakers; it cannot be connected to active speakers or constant-voltage speakers.
2. To turn on the unit, set the front switch to the “ON” position. If you need to use trigger activation, set the switch to the “AUTO” position.
3. The LSYSAQA7 operates on 24V–48V DC. Higher voltage provides greater power, but the voltage must not exceed 48V; otherwise, the amplifier will be damaged. The power connector is 5.5 × 2.5, with the inner pin positive and the outer pin negative.
4. The negative terminals of the amplifier’s left and right channels must not be connected together; doing so will burn out the amplifier.
5. Gently press the volume knob on the front panel to select different input modes; the corresponding indicator light will illuminate.
6. The gain switch applies to all inputs.
7. The AUX output volume is fixed and matches the input volume, making it convenient for connecting to an active subwoofer or another amplifier.
