CHAPTER 3: POWERING ULTRA XP LOUDSPEAKERS
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.
TIP:
For complete information on using the
MPS-488HP IntelligentDC power supply, refer
to the MPS-488HP Operating Instructions
(PN 05.205.005.01).
To power Ultra XP loudspeakers with the MPS-488HP:
1. Power off the MPS-488HP.
2. Connect audio sources (from a mixer or processor) to the
MPS-488HP channel inputs. Use balanced XLR cables.
3. Use the MPS-488HP Link switches to route channel
inputs to channel outputs. For information on the
MPS-488HP Link switches, refer to the MPS-488HP
Operating Instructions (PN 05.205.005.01).
4. Connect loudspeakers to the MPS-488HP channel out-
puts. Use composite cables (such as Belden 1502 or
equivalent) wired for both DC power and balanced audio
and outfitted with the appropriate connectors.
When connecting loudspeakers equipped with Phoenix

connectors to the MPS-488HPp power supply, use
Phoenix 5-pin male to Phoenix 5-pin female cables.

TIP:
You can use two separate cables for loud-
speaker connections: a 2-conductor cable for
DC power and a 3-conductor cable for balanced
audio, both attached to a single Phoenix connector
on each cable end. This allows you to use a larger
