Balanced jack/XLR inputs with balanced direct XLR outputs.
Complete protection against shorted outputs, mismatched loads, overheating and DC input/output.
Efficient heat sinks and self-contained forced air cooling system.
Three year warranty and guarantee.
Precautions
Although your amplifier is protected from external faults, the following safety precautions are recommended:
1. There are important differences between the CH 1&2 Hi outputs and the Sub&Hi outputs. Do not connect
B12 cabinets directly to the Sub&Hi outputs. Connect B12 cabinets to the CH 1&2 Hi outputs using the
B12's top input speakon, or the link out Speakon on B15 Sub cabinets to the B12's lower input speakon.
B15 Subs must be connected to the Sub&Hi outputs with 4 core cable for the B12's to operate.
2. Switch off the amplifier or turn down the inputs before connecting to the in/out XLR's.
3. Do not short the ground lead of an output cable to the input signal ground. This will form a ground loop
and may cause oscillations.
4. Do not operate the amplifier from AC mains in excess of 10% variation above or below the selected line
voltage, and only at the specified line frequency.
