CHAPTER 3: MDM-832 FRONT AND REAR PANELS
MDM-832 FRONT PANEL
The MDM-832 front panel includes audio outputs, RMS
FT-10 network connectors, powerCON 20 AC outputs, 15 A
breaker switches, and LEDs for monitoring AC voltage pres-
ence at each circuit breaker.
MDM-832 Front Panel
Audio Outputs
The MDM-832's eight front-panel audio outputs provide bal-
anced audio to connected loudspeakers, routed from the
audio inputs on the rear panel of the MDM-832. Audio out-
puts are available as either XLR 5-pin male connectors or
XLR 3-pin male connectors.
MDM-832 Audio Outputs (5-pin)
XLR 5-pin male connectors (pin 1, ground; pin 2, signal pos-
itive; pin 3, signal negative; pins 4–5, RMS) deliver both bal-
anced audio and RMS signals to connected loudspeakers
with a single, composite cable.
MDM-832 Audio Outputs (3-pin)
XLR 3-pin male connectors (pin 1, ground; pin 2, signal pos-
itive; pin 3, signal negative) deliver balanced audio to con-
nected loudspeakers.
NOTE:
For information on cable requirements
for any loudspeaker, refer to its operating
instructions. For information on composite cables
available from Meyer Sound, see Appendix A, "Com-
posite Cable."
Breaker Switches
(Channel 1–4, Channel 5–8)
MDM-832 Breaker Switches
Two front-panel 15 A breaker switches toggle AC power to
the AC Outputs. One breaker switch corresponds to AC
Outputs 1–4; the other breaker switch corresponds to AC
Outputs 5–8.
Each set of four MDM-832 outputs is capable of powering
groups of loudspeakers that have a sum total maximum
long-term continuous current draw equal to or below the rat-
ing of the MDM-832 breakers. Load ratings are indicated
adjacent to the breaker switches on the front panel. For
more information on load ratings, see Appendix C,
"MDM-832 Specifications."
Voltage LEDs (1–2)
Each Voltage LED indicates AC voltage presence for the
corresponding breakers and connected loudspeakers.
Voltage Presence LEDs
State
Cause
Unlit
The MDM-832 is not con-
nected to mains power, or
breakers are not switched
on.
Lit
The MDM-832 is con-
nected to mains power
and breakers are switched
on.
Recommended Action
Verify the MDM-832 AC
Input is connected to
mains power; inspect the
power cabling; switch the
breakers to the ON posi-
tion.
None.
