UP-4XP OPERATING INSTRUCTIONS

CONNECTING UP-4XP LOUDSPEAKERS TO
THE MPS-488 EXTERNAL POWER SUPPLY
The original MPS-488 was designed for use with the
MM-4XP miniature loudspeaker. While the MPS-488 can
power up to eight MM-4XP loudspeakers, it can only power
up to four UP-4XP loudspeakers (due to the UP-4XP’s
higher power requirements and current draw).
Because the MPS-488 can power a maximum of four
UP-4XP loudspeakers, the loudspeakers should only be
connected to Channel Outputs 1, 3, 5, and 7. Do not use the
even-numbered channel outputs.
NOTE: These guidelines do not apply to the
MPS-488HP external power supply, which can
drive up to eight UP-4XP loudspeakers.
NOTE: The MPS-488HP external power supply
replaces the MPS-488 model, which was origi-
nally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with UP-4XP loud-
speakers and can drive up to four units (using every
other Channel Output).
