How to use

Install the amplifier into a standard 19-inch rack or place it on a stable surface ensuring adequate ventilation around the unit. Connect input signals from a mixer or preamplifier using the appropriate balanced or unbalanced inputs supported by your system. Match speaker impedance and connect loudspeakers using properly rated speaker cables and secure connectors. Power the unit from a 230 V AC, 50 Hz outlet and switch the amplifier on following the recommended power-up sequence for your audio system to avoid speaker thumps.

Recommendations

Ensure adequate ventilation and avoid stacking other heat-generating equipment directly on top of the amplifier. Verify speaker impedance and use appropriate speaker protection or limiters if operating near maximum power to protect loudspeakers. For reliable long-term operation, perform regular visual inspections of connectors, cabling, and mounting hardware.
