MM-10 OPERATING INSTRUCTIONS

MM-10ACX SATELLITE OUT CONNECTORS
The Satellite Out connectors deliver DC power (48 V DC)
and balanced audio to satellite loudspeakers: up to two
MM-4XPs, or a single UP-4XP (due to its higher power
requirements and current draw). The source audio for the
satellite loudspeakers is received from the MM-10ACX’s
Audio 1 In and Audio 2 In connectors. The DC power for the
satellite loudspeakers is generated by the MM-10ACX’s
onboard DC power capabilities.
The Satellite Outs can be equipped with either Phoenix 5-
pin male connectors or EN3 5-pin female connectors.
CAUTION: When wiring cable connections for
the Satellite Outs, it is extremely important that
each pin in the connector is wired correctly. Make
sure the 48 V DC from the MM-10ACX is wired
directly (and only) to the 48 V DC pins on the connec-
tor for the satellite loudspeaker, and that the polarity
is observed (negative to negative, positive to positive)
to avoid damage to the loudspeaker. In addition,
make sure the audio pins are wired correctly; polarity
reversals for audio signals can affect system perfor-
mance.
Phoenix Outputs
The MM-10ACX Satellite Outs are available as Phoenix 5-
pin male connectors with three pins for balanced audio
(positive, negative, and shield) and two pins for DC Power
(positive and negative). These pins are clearly labeled on the
MM-10ACX rear panel. A single composite cable (such as
Belden 1502) wired for both DC power and balanced audio
can be used to connect to each satellite loudspeaker.
When equipped with Phoenix Satellite Outs, the MM-10ACX
comes with Phoenix 5-pin female cable connectors for
assembling loudspeaker cables. For information on cable
requirements for the satellite loudspeaker, refer to its operat-
ing instructions. For information on cables and cable acces-
sories available from Meyer Sound, see Appendix A,
“MM-10 Accessories.” For information on cable assembly,
see Appendix C, “Phoenix and EN3 Cable Assembly.”
EN3 Outputs
The MM-10ACX Satellite Outs are available as EN3 5-pin
female connectors with three pins for balanced audio (posi-
tive, negative, and shield) and two pins for DC Power (posi-
tive and negative). These pins are clearly labeled on the
MM-10ACX rear panel. A single composite cable (such as
Belden 1502) wired for both DC power and balanced audio
can be used to connect to each satellite loudspeaker.
When equipped with EN3 Satellite Outs, the MM-10ACX
comes with EN3 5-pin male cable connectors for assem-
bling loudspeaker cables. For information on cable require-
ments for the satellite loudspeaker, refer to its operating
instructions. For information on cables and cable accesso-
ries available from Meyer Sound, see Appendix A, “MM-10
Accessories.” For information on cable assembly, see
Appendix C, “Phoenix and EN3 Cable Assembly.”
MM-10ACX INPUT SELECT SWITCH
The Input Select switch determines the audio source signal
for the subwoofer. When the switch is in the down position
(SUB CH), the source signal is received from the Subwoofer
Audio In connector. When the switch is in the up position
(SUM CH 1 + 2), the source signal is received from the
Satellite 1 and Satellite 2 Audio In connectors and is
summed.
