APPENDIX D: MPS-488 SPECIFICATIONS
NOTE:
The MPS-488 was originally 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 HMS-10s (because of the HMS-10’s
additional current draw).
MPS-488 Specifications
FRONT PANEL
LEDs
Eight LEDs to indicate output voltage
Eight LEDs to indicate load current
Eight LEDs to indicate load current
REAR PANEL
Audio Inputs
Eight channels of XLR female connectors with Link switches to route to outputs
Outputs
MPS-488
P
model includes eight channels of Phoenix 5-pin male connectors (three pins for bal-
anced audio, two pins for DC power); MPS-488
E
model available with EN3 5-pin female connectors
Note: Because the MPS-488 can power a maximum of four HMS-10 loudspeakers, the HMS-10s
should only be connected to channel outputs 1, 3, 5, and 7. Do not use the even-numbered chan-
nel outputs.

Operating Voltage
100–240 V AC; 50/60 Hz
Turn On/Turn Off Points
90–264 V AC; 50/60 Hz
Note: No automatic turn-off voltages. Voltages above 265 V AC are fuse protected but may cause
permanent damage to the power supply. Voltages below 90 V AC may result in intermittent opera-
tion.
