Redback A 4116 Operating Instructions

REDBACK A 4116 15W Stereo Amplifier
Overview
The Redback A 4116 stereo amplifier is super compact
and ideally suited to smaller PA system installations.
Designed around the ST TDA7492 IC it offers virtual
"destruction proof" operation even under sever misuse
such as over voltage, over temperature, over load and
short circuit speaker line conditions. The unit will
automatically shut down when overloaded and will restore
to normal operation when the fault condition is removed.
The A 4116 can be used as a stand alone/ bench mount
amplifier or can be rack mounted when used in
conjunction with optional hardware (H 4990).
Features
• 15W RMS Output into an 8Ω load
• 1 Stereo RCA input
• 1 Music input (3.5mm)
• 1 Line/Sub output
• 4-16Ω output
• 240VAC operation

Trouble Shooting

DISTORTED OUTPUT
Check that the speaker type is correct for the output that
you are using. Check for any short circuits on the speaker
line.
VERY LOW OUTPUT
Make sure that the input is the correct level (check for
shorted connectors). Check for any short circuits on the
speaker line.
AMPLIFIER KEEPS ON CUTTING IN & OUT
Check speaker types, ratings and for any short circuits on
the speaker line.
