This section presents each of the configurations where a DA950-U amplifier can be used, and
specifies the correct wiring and settings configuration in each case.

General Considerations
• When the DA950-U amplifier is used to power a subwoofer and satellites, 3-channel mode should be used.
• When using 3-channel mode, Zone 2 input is disabled. Use Zone 1 input. The DA950-U will output the bass
signal to the dedicated subwoofer connector, and the mid/high signal to the “Zone 2 / 3-CH SAT” outputs.
• Some rewiring on the euroblock connectors will be necessary when replacing a 3-channel DA-415. This
rewiring is indicated on each diagram, where applicable.
• When the DA950-U is used to power full-range speakers (no subwoofer) 4-channel mode should be used.
• Bass Boost mode should only be used with the Virtuo Floor Stand acoustics, or with the PowerPack 725 (or
other speaker systems as specified by TouchTunes.) Activating this mode for non-indicated speakers could
lead to degraded sound quality, and even damage to the connected speakers.
• For configurations that predate Virtuo, the schematics in the following pages show a JCB computer’s
connections panel, but it’s also possible to connect to an MJS computer, as the only difference is in the
position of the audio zone connectors.
• Always turn off the DSP EQ / Bass Boost software option in the operator interface of the jukebox before
proceeding with the installation or replacement of a DA950-U. Only turn it back on after testing the sound and
determining that it is necessary.
• Except for the PowerPack 725 section, the following pages cover the replacement of a DA415 with a DA950-
U. If you are replacing a DA950-U with another DA950-U, simply set and wire the replacement exactly like the
original.
