Rear Panel Description
1
Universal Voltage Input:
via a miniature IEC 60320 C6 appliance inlet. This mates with an IEC 60320 C5 line cord (USA
domestic). Do
not
lift the ground connection!
2
USB
connection:
Attach the included USB cable from here to the computer. The blue LED illuminates when the cable is con-
nected and receiving power. USB delivers two stereo inputs from the computer to the mixer (
USB 1
and
USB 2
), and one stereo
record signal from the mixer to the computer.
3
HOUSE
Output:
The front panel
HOUSE LEVEL
control affects the volume at this Output. Connect either the XLR or ¼" TRS
(tip-ring-sleeve) jacks to a balanced equalizer or amplifier. Both Output types may be used simultaneously if needed. Though not
recommended, unbalanced ¼" TS (tip-sleeve) cables may be used for short runs (under 3 meters [10 feet]) to an amplifier with
unbalanced inputs. See the RaneNote
“Sound System Interconnection”
for wiring recommendations.
4
AUX
Output:
This delivers the same signal as the
HOUSE
Output, but has its own rear panel
LEVEL
control.
This Output is
not
af-
fected by the front panel
HOUSE LEVEL
control.
These balanced ¼" TRS (tip-ring-sleeve) Outputs connect to a balanced equalizer
or amplifier (for a possible second listening zone) and follow the same interconnection rules as above.
5
MIC TO USB RECORD
switch:
In the
YES
position the Mic signal along with the Program mix is routed to the USB record output.
In the
NO
position only the Program mix is sent to the USB record output.
6
INPUTS 1 & 2
:
These stereo Inputs are each switchable from a
PHONO
(RIAA) stage for magnetic cartridges (switch
in
) to a
LINE
level Input suitable for any line level device such as a CD player (switch
out
). Each of these may be assigned to
PROGRAM A
or
B
using the front panel
INPUT
selectors. The
PHONO GROUND
screw connects those extra wires coming out of the turntables.
7
MIC
Input jack:
Accepts either a ¼" balanced (TRS) or unbalanced (TS) microphone plug, controlled by the front panel
MIC
LEVEL
control.

brication. This treatment extends longevity and can make a used
fader as good as new. The fader assembly must be removed from
the MP 4 for proper cleaning. We recommend any of the follow-
ing cleaning solutions:
