Ensure that the heatsink is not obstructed and that adequate airflow can circulate around it to ensure safe and reliable operation. The amplifier accepts either balanced or unbalanced signals, through a detachable Phoenix-style connector or a single RCA connector. Nominal sensitivity of the Balanced input is +4dBu and -10dBu for the unbalanced input. A rotary Gain Control is provided to attenuate the volume. Both models are fitted with 4 threaded inserts on the rear for attaching the supplied mounting bracket. Access to the mounting points is gained by removing the four screws and the blank cover plate.
