THE MM-4XP MINIATURE LOUDSPEAKER
The MM-4XP miniature loudspeaker is a self-powered loudspeaker designed for high-quality distributed systems.
Housed in a compact aluminum enclosure, the MM-4XP is
especially suitable for installations involving space limitations and visibility concerns. The loudspeaker’s proprietary
4-inch cone transducer, manufactured at Meyer Sound's
Berkeley factory, delivers an impressive maximum peak SPL
of 113 dB (measured with music referred to 1 meter), and
has a wide operating frequency range of 120 Hz to 18 kHz
with very low distortion. The MM-4XP exhibits the same high
intelligibility and flat frequency and phase responses for
which Meyer Sound loudspeakers are known. Peak and rms
limiters regulate loudspeaker temperatures and excursion,
ensuring that the MM-4XP performs exceedingly well even
when driven into overload.

MM-4XP Loudspeaker
The MM-4XP's amplifier and signal-processing circuits are
designed to store DC power and tolerate voltage drops,
thereby accommodating light-gauge cables and long cable
runs. The MM-4XP receives balanced audio and DC power
from a SwitchCraft
®
EN3™ 5-pin male connector on its rear
panel. The sealed EN3 connector provides protection
against harsh environmental conditions when the MM-4XP
is installed outdoors.

CHAPTER 1: INTRODUCTION
MM-4XP loudspeaker systems require an MPS-488 external
power supply. The single-space 19-inch rack unit receives
eight channels of balanced audio from its XLR female inputs
and routes the audio, along with 48 V of DC power, to its
eight Channel Outputs. The outputs — equipped with either
Phoenix 5-pin male connectors on the MPS-488
EN3 5-pin female connectors on the MPS-488
P model, or
E model —
can deliver DC power to the MM-4XP loudspeakers at cable
lengths of up to 300 feet with just 1 dB of loss in peak SPL
using 18 AWG wire. The use of composite multiconductor
cables (such as Belden
®
1502) allows a single cable to carry
both audio and DC power to the MM-4XP. Longer cable
lengths are possible for moderate applications that don't
drive the loudspeakers to maximum output, or for installations with heavier wire gauges.
MPS-488P Power Supply
The MPS-488 front panel has two LEDs per output channel
that provide useful feedback on the status of the system.
The Voltage LEDs indicate when voltage is present for each
output channel. The Load Current LEDs indicate when a
loudspeaker is connected to an output and glow brighter as
the signal level increases.
The MM-4XP’s extruded aluminum enclosure acts as a heat
sink to dissipate heat from the driver's voice coil. The enclosure is available in standard white or black anodized finishes
with a perforated steel grille. It can also be custom painted
to match specific color schemes. The MUB-MM4XP Ubracket mounts the loudspeaker on walls and ceilings at
adjustable angles. The U-bracket is also available in standard white or black anodized finishes and custom colors.

CHAPTER 2: THE MPS-488 POWER SUPPLY
The MPS-488 power supply was designed to deliver DC
power and balanced audio to up to eight MM-4XP loudspeakers. The MPS-488 is a switched-mode regulated
power supply that occupies one space in a standard 19-inch
rack. There are two MPS-488 models available: the
MPS-488
tors, and the MPS-488
P, which has Phoenix 5-pin male output connec-
E, which has EN3 5-pin female output
connectors.
THE MPS-488 FRONT PANEL
The MPS-488 front panel includes a power switch, LEDs for
monitoring each of the eight loudspeaker channels, and
fuses for each channel.
MPS-488P Power Supply Front Panel
AC Power
The MPS-488 is powered on and off with the AC Power
switch.
Voltage and Load Current LEDs (1–8)
The Voltage and Load Current LEDs are useful for verifying
whether each of the eight Channel Outputs have voltage
and whether the connected MM-4XP loudspeakers are
receiving DC power and audio.
Load Current LEDs (1–8)
The green Load Current LEDs indicate whether a loudspeaker is connected to the channel and receiving power.
As a channel’s audio signal increases, its LED glows
brighter. If an LED is not lit, check that the channel’s Voltage
LED is lit (the fuse is working) and verify the cable connection to the loudspeaker.
Fuse Slow Blow (1–8)
Each loudspeaker channel is protected with its own fuse. A
maximum of one loudspeaker can be connected per channel; connecting more than that could cause the fuse to be
tripped.
NOTE: When replacing fuses, make sure to
use a 2-amp, 250-volt slow-blow fuse (T2A250V). These fuses are available from Meyer Sound
(PN 420.027).
THE MPS-488 REAR PANEL
The MPS-488 rear panel includes an AC connector, eight
Channel Inputs for receiving source audio, and eight Channel Outputs for delivering DC power and balanced audio to
the MM-4XP loudspeakers. The rear panel is different for the
two MPS-488 models: the MPS-488
male output connectors, and the MPS-488
female output connectors.
P has Phoenix 5-pin
E has EN3 5-pin
MPS-488 Channel LEDs and Fuses
Voltage LEDs (1–8)
The blue Voltage LEDs indicate whether voltage is present
for each of the eight Channel Outputs. These LEDs should
be lit when the MPS-488 is powered on. If a channel is not
lit, its fuse may need to be replaced. If a group of two Voltage LEDs is not lit (1–2, 3–4, 5–6 or 7–8), one of the four
MPS-488 internal power supplies may have failed.

AC Input
The MPS-488 has a PowerCon twist-lock AC connector
(line, neutral/line, earth). The connector can accept different
power cord types for outlets used throughout the world.
Make sure to use the correct power cord for the AC power in
your area. The MPS-488 operates at an AC voltage range of
100–240 V at 50–60 Hz.

Channel Inputs
Up to eight channels of balanced audio are received via the
MPS-488’s eight Channel Inputs. The inputs are equipped
with XLR female connectors (pin 1, ground; pin 2, signal
positive; pin 3, signal negative) and have an input impedance of 10 kOhms. Make sure to use standard balanced
XLR cables with all three pins connected on both ends.
MPS-488 Channel Inputs
Channel Inputs default to being routed to their corresponding Channel Outputs but can also be routed to adjacent outputs with the Link switches, though this affects their input
impedance (see “Input Impedance for Linked Channel
Inputs” on page 11).
Link Switches
Link switches determine how Channel Inputs are routed to
Channel Outputs. When a Channel Input’s Link switch is disabled (set to the down position), the input is only routed to
its corresponding Channel Output (for example, Channel
Input 1 routed to Channel Output 1). When a Link switch is
enabled (set to the up position), the input is routed to its corresponding Channel Output and the next adjacent Channel
Output. If multiple, adjacent Link switches are enabled, the
input is routed to each adjacent Channel Output.
How Linked Input Channels Are Routed
The following examples illustrate how the Link switches for
Input Channels 1–4 can be used to affect their routing to
Channel Outputs.
■ When Link switches 1–3 are off, Channel Inputs 1–4 are
routed to their corresponding Channel Outputs.
■ When Link switch 1 is on and Link switches 2–3 are off,
Channel Input 1 is routed to Channel Outputs 1–2, and
Channel Inputs 3–4 are routed to their corresponding
Channel Outputs. Channel Input 2 is inactive.
■ When Link switches 1–2 are on and Link switch 3 is off,
Channel Input 1 is routed to Channel Outputs 1–3, and
Channel Input 4 is routed to Channel Output 4. Channel
Inputs 2 and 3 are inactive.
MPS-488 Audio Input
NOTE: Channel Inputs are inactive when the
Link switch for their preceding Channel Input is
enabled. Connections should not be made to inactive
Channel Inputs.

■ When Link switches 1–3 are on, Channel Input 1 is
routed to Channel Outputs 1–4. Channel Inputs 2–4 are
inactive.
