Outputs
Main/Zone/Booth
All analog outputs come from the same “Main Mix” signal.
Main, Booth and Zone Outputs each have their own Level con-
trol.
e Main output is from unbalanced RCA and balanced
XLRjackswithpin2“hot”perAESstandards(XLRpreferred*).
If the Main output feeds a mono PA system, engage the Mono
switch on the rear of the MP25. If the Main output is able to
clip the input to the PA system when the front panel Main Level
control is at maximum, reduce the maximum output level using
the rear panel Max Out control.
e Booth and Zoneoutputsarefrombalanced¼˝TRS(tip-
ring-sleeve)jacks.BoothandZoneoutputsincludeauto-mono on
both left and right connections. Plug in only one side to receive a
mono signal. Plug into both jacks to receive a stereo signal.
*Ranerecommendsbalancedwiringforthestrongestsignal
and rejection of hum and noise. If your cable to the amp rack
islessthan10feet(3meters),youcanusuallygetawaywithan

RaneNote “Sound System Interconnection” included with this
manual or at www.rane.com for details on cable wiring.
Record Outputs
Record outputs are a direct feed from the main mix. ere are
no level controls between the mix and these outputs. e main
mix is available in three dierent formats for recording: unbal-
ancedanalogRCA,24-bit48kHzS/PDIF,andUSB(onrecord
channelsix).
FlexFX Send/Return

with outboard eects processors. e Send and Return signals
areonstereounbalanced¼˝TSjacks.eLeftandRightSend
jacks provide auto-mono operation. Simply plug in one side for
mono, or both sides for stereo. e Return jack provides similar
operation. Plugging into either the left or right return jack sends
thesignaltoboththeleftandrightFlexFXLoopreturnchan-
nels. Plugging into both jacks separates the left and right return
channels.
USB
Connect your computer to the USB port on the MP25 to send
uptotwenty-twochannelsofaudioto/fromyourfavoritemulti-
track mixing, beat-making, looping, sampling, and record-

Crossfader Questions and Answers
Q: Can I install magnetic crossfaders in any other mixer?
A: e connectors may be similar, but the circuits are very dier-
ent. Connecting the fader to anything other than the intend-
ed cable in the MP25 could permanently damage it.
Q: Can I install another crossfader in my MP25?
A: No. e cable connections are specially designed for Rane
magnetic faders.

USB Drivers
e MP25 includes high-performance, high-stability ASIO and
Core Audio device drivers. e driver allows audio applications
to play and record audio via the MP25’s ve stereo playback
and six stereo record USB channels. e drivers are designed
for incredibly low audio latency, eliminating perceptible delay
between control input to audio applications and the resulting
audible eect.

befoundatwww.rane.com/mp25.html.
ASIO (Windows)
e MP25 uses a low-latency, multi-client, ASIO device driver to
interface with applications on Windows operating systems.
Multi-client ASIO allows dierent audio software applica-
tions to simultaneously stream audio to and from the MP25. If
the same playback channel is selected in more than one applica-
tion, the driver mixes the audio from the dierent applications
before streaming it to the mixer.

Maintaining the Magnetic Crossfader
ere are no electrical contacts to clean!
e crossfader in the MP25 is designed with materials highly
resistant to corrosion and most chemicals. While the crossfader
will handle millions of operations, it may become dirty over
time. Bad things may be spilled or sprayed into the crossfader. In
eithercase,thecrossfaderisnotdamagedandthesoundquality
is unaected. Cleaning is only required to maintain the feel of the
crossfader.
e crossfader is self-lubricating and with normal use, should
notrequireadditionallubrication.Ifyouwish,youcanusea
light silicone lubricant rated for use with electrical parts. is
willhelpmaintainthefeel.WerecommendCaigDeoxITFader-
Lube F100spraylubricant.

Never use a heavy lubricant or grease.Doingsowillnotdam-
age the faders, but can undo the feel. If grease was used, it may
be removed by following the cleaning instructions.
