Redback® A 4395A 500W Mixer Amplier
www.redbackaudio.com.au Redback® Proudly Made In Australia 7
POWER SUPPLY
The amplier 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 conrm the capacity of the DC power supply used.
24V DC OUTPUT
A constant 24V output terminal has been provided to power ancilliary 24V devices. The output has a maximum current
draw of 1 amp. If more than 1 amp is drawn from the output, internal polyswitches will disconnect the output. These will
reset once the current draw is reduced.
24V BACKUP BATTERY CHARGING
The A 4395A amplier includes a charging circuit so that a backup battery connected to the ampliers 24V DC Input can
be trickle charged. The battery charger is connected to the battery internally when the link is tted to the charging link
connector (see Fig 5 for more details). The battery will be charged at approximately 300mA.

DIP Switch settings
The A 4395A amplier has a set of options which are enabled via the DIP switches 1-4. See Fig 6.
DIP 1 sets the input level sensitivity for input 1 (either the balanced 3 pin XLR or Dual RCA’s).
DIP 2 enables the VOX muting. When the VOX is active input 1 will mute input 2.
DIP 3 enables the phantom power to the XLR connector on input 1.
DIP 4 sets the input level sensitivity for input 2.
