How to use

Place the amplifier in a well-ventilated rack or on a stable surface, ensuring adequate airflow around the unit. Connect the AC mains supply rated for 230 V, 50 Hz, and verify that the venue mains can support the amplifier’s typical power consumption. Use the clamp terminals to attach speaker cables with secure bare-wire terminations or suitable ferrules; ensure correct polarity for each channel. Adjust input levels from the connected mixer or source to match the amplifier’s input sensitivity and avoid input clipping. Monitor the amplifier during initial use to confirm stable operation and acceptable temperature.

Recommendations

For reliable long-term operation, allow at least one rack unit of free space above and below the amplifier for ventilation, avoid enclosing the unit in unventilated cabinets, and use appropriately rated speaker cables to minimize voltage drop and maintain sound quality.
