CHAPTER 3: POWERING MM-10XP SUBWOOFERS WITH THE MPS-488HP
20
a larger gauge for the DC cable so you can achieve
longer cable runs (see “Cable Lengths and Cable
Gauges for MM-10XPs” on page 13).
■ When connecting MM-10XP subwoofers equipped with
EN3 connectors to the MPS-488HPe power supply, use
EN3 5-pin male to EN3 5-pin female cables.
■ To join two EN3 cables, one with an EN3 5-pin male
cable mount connector to one with an EN3 5-pin female
cable mount connector, use an EN3 5-pin female-to-
male cable coupler (PN 28.163.033.01).
CAUTION: Make sure MM-10XP loudspeaker
cables are wired correctly. For details on
assembling loudspeaker cables, see Appendix C,
“Phoenix and EN3 Cable Assembly.”
5. Power on the MPS-488HP and monitor the LEDs on its
front panel to verify the connections (see “Voltage and
Load Current LEDs (1–8)” on page 15).
6. Check the LEDs on the MM-10XP rear panels and verify
they are green (ready to reproduce audio).
7. Enable output from the audio sources (from the mixer or
processor) connected to the MPS-488HP.
POWERING MM-10XP SUBWOOFERS WITH
THE ORIGINAL MPS-488
The original MPS-488 was designed for use with the
MM-4XP miniature loudspeaker. While the MPS-488 can
power up to eight MM-4XPs, it can only power up to four
MM-10XPs (due to the MM-10XP’s higher power require-
ments and current draw).
Because the MPS-488 can power a maximum of four
MM-10XPs, the MM-10XPs should only be connected to
channel outputs 1, 3, 5, and 7. Do not use the even-num-
bered channel outputs.
