1. POWER CONNECTOR AND AC FUSE Power connector is designed for main powers connecting to amplifier. This connector is combined with fuse holder and 2.5A 250V fuse for MA 120 and 1.6A 250V fuse for MA 60 amplifiers. 2. OUTPUT AND +24V DC TERMINAL 24V DC terminal is designed to power up the amplifier when the main power is unavailable.
5. AUX INPUT GAIN SELECTOR This selector is designed to adjust the gain for the AUX input. There are available three gain settings: -8 dBu, -12dBu and -18dBu. 6. BALANCED XLR INPUTS These balanced XLR inputs are universal, the gain (MIC or LINE) of these inputs are selectable by switch located near the input in the rear panel.

Each of the amplifier channels can run only one output configuration at the same time. Operating amplifiers using 4 ohm and 70 or 100 volt concurrently may cause damage to the amplifier or connected speakers. There is possibility to connect external power supply, external battery etc. Please find the connection example.
