MPS-488HP INTELLIGENTDC HIGH-POWER
EIGHT-CHANNEL POWER SUPPLY
Ultra XP loudspeakers require an external MPS-488HP
IntelligentDC power supply. The single-space 19-inch rack
unit distributes DC power and balanced audio to up to eight
Ultra XP loudspeakers, or other Meyer Sound IntelligentDC
loudspeakers. Composite multiconductor cables, such as
Belden 1502 or equivalent, can deliver both DC power and
balanced audio to loudspeakers at cable lengths up to
150 feet with just 1 dB of loss in peak SPL using 18 AWG
wire. Longer cable runs are possible with heavier gauges.
Meyer Sound’s RMS remote monitoring system is optionally
available for the MPS-488HP.
CAUTION: Disconnect the mains plug before
disconnecting the power cord from the
MPS-488HP.
TIP: For complete information on using the
MPS-488HP IntelligentDC power supply, refer
to the MPS-488HP Operating Instructions
(PN 05.205.005.01).
LATENCY OF ULTRA XP LOUDSPEAKERS
There is a very small latency of 1.58 ms for Ultra XP loud-
speakers when compared to their equivalent AC-based
models. This does not represent a problem when using
Ultra XP loudspeakers with other Ultra XP loudspeakers.
When mixing Ultra XP and AC loudspeakers in close prox-
imity, the small latency can be easily addressed with a delay
setting in a loudspeaker processor such as Meyer Sound’s
Galileo 408 or Galileo 616.
