Redback® A 4395A 500W Mixer Amplifier SPEAKER CONNECTIONS Speakers with a total impedance or 4-16Ω may be connected to the terminals marked 4-16Ω on the rear of the amplifier. Speakers fitted with line transformers (either 70V or 100V) may be connected to the corresponding terminals on the rear of the amplifer. Always ensure the total load of the fitted speakers does not exceed the rated output of the amplifier (ie 500 watts) otherwise damage may result.

Redback® A 4395A 500W Mixer Amplifier POWER SUPPLY The amplifier operates on 230V AC or 24V DC primarily for battery backup operation. Ensure power is switched OFF at the front panel before connecting either mains power to the IEC socket or 24V DC to the screw terminal input. As high currents may be drawn when operating from a 24V DC supply confirm the capacity of the DC power supply used. 24V DC OUTPUT A constant 24V output terminal has been provided to power ancilliary 24V devices.

Redback® A 4395A 500W Mixer Amplifier TROUBLE SHOOTING If the REDBACK Phase 4 amplifier fails to deliver the rated performance, check the following: No Power, No Lights Make sure amplifier power switch is on. Make sure mains power switch is on at the wall. Check the mains and DC fuse. Replace with only the correct type and rating. Over rated fuses will invalidate warranty. Distorted Output Check that the speaker type is correct for the output that you are using (ie. 4-16Ω, 70V or 100V line).
