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.
