Audio Interface Kit #34109453
The AMI Audio Interface is used to convert unbalanced audio
signals from an AMI preamplifier to balanced audio signals
which are compatible with TouchTunes amplifiers.
The AMI Audio Interface is used in the Ovation/Ovation 2
and Allegro MX1 conversion kits. However, each kit requires
a different configuration of the AMI Audio Interface. The
configuration is changed by moving (4) jumpers on the circuit
board inside the Interface.
1.
To open the Audio Interfaced, remove (1) screw between
the RCA Jacks on the side and remove (4) screws on the
bottom. Remove the top cover to access the circuit
board.
2.
Locate the (4) jumpers on the board. Move all four
jumpers to either the 1-2 position (for Allegro MX1) or
the 2-3 position (for Ovation/Ovation 2). Note: All four
jumpers must to be set in the same position.
3.
Replace the cover and the screws.
The jumpers are used to change the routing of
audio signals from CH3 and CH4 to OUT A and
OUT B as shown below.
