Allegro MX-1 / MX-1v
The Allegro MX-1 contains two DA415 amps: one is assigned to one zone and drives the internal subwoofer
and satellite speakers and is referred to as 3-Channel, and one is assigned to drive the remaining two zones,
as two full-range stereo pairs and is referred to as 4-channel. We will cover both amps separately, while
highlighting the fact that the DA950-U can replace either the 3-Channel DA415 or the 4-Channel DA415 (i.e.,
two identical DA950-U will be able to replace both amps in the MX-1.)
Replacing the 3-Channel DA415
1. Turn off MX-1 jukebox.
2. Disconnect all cables connected to the DA415 amplifier:
a) Euroblock
b) Subwoofer wire
c) Power cable
d) CAT-5/RJ-45 cable/connector coming from JCB computer
3. Remove the four screws that hold the amplifier in place.
4. Pull the DA415 out of the jukebox.
5. Set the switches on the DA950-U to 3-channel and Bass Boost OFF.
6. Place the DA950-U into the position previously occupied by the DA415.
7. Fasten the DA950-U using the screws you just removed from the DA415.
8. Reconnect all the cables.
a) Euroblock
b) Subwoofer wire
c) Power cable
d) CAT-5/RJ-45 cable/connector coming from JCB computer to zone 1 on DA950-U
Note: Some wires may have to be moved on their euroblock connectors due to differences between
the two amplifiers. See the wiring schematic below.
9. Check that the switches on the amplifier are set to 3-channel and Bass Boost OFF.
10.
Turn the MX-1 jukebox on, wait for it to boot, then play a song to verify that the internal subwoofer and
satellites inside the MX-1 are playing the music normally.
