CHAPTER 3: POWERING UP-4XP LOUDSPEAKERS

CONNECTING UP-4XP LOUDSPEAKERS TO

THE MPS-488HP

EXTERNAL POWER SUPPLY

UP-4XP loudspeakers require a Meyer Sound 48 V DC

external power supply, such the MPS-488HP. The single-

space 19-inch rack unit receives eight channels of balanced

audio from its XLR female Channel Inputs and routes the

audio, along with 48 V of DC power, to its eight Channel

Outputs. The Channel Outputs, which are available as either

Phoenix 5-pin male connectors or SwitchCraft EN3 5-pin

female connectors, can deliver DC power to up to eight

UP-4XP loudspeakers. Cable lengths up to 150 feet for DC

power are possible when using 18-AWG wire, with just 1 dB

of loss in peak SPL. Longer cable runs are possible for mod-

erate applications that don't drive the loudspeakers to maxi-

mum output, or for installations with heavier wire gauges.

The use of composite multiconductor cables (such as

Belden 1502 or equivalent) allows a single cable to carry

both DC power and balanced audio to the UP-4XPs.

TIP: For complete information on using the

MPS-488HP external power supply, refer to the

MPS-488HP Operating Instructions.

To connect UP-4XP loudspeakers to 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 the desired Channel Outputs. For information

on the MPS-488HP Link switches, refer to the

MPS-488HP Operating Instructions.

4. Connect the UP-4XP loudspeakers to the MPS-488HP

Channel Outputs. Use composite cables (such as

Belden 1502 or equivalent) wired for both DC power and

balanced audio and outfitted with the appropriate con-

nectors.

■ When connecting UP-4XP 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

UP-4XP loudspeaker connections: a 2-conduc-

tor 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 gauge for the DC cable so you can achieve

longer cable runs (see “Cable Lengths and Cable

Gauges for UP-4XP Loudspeakers” on page 13).
