Solo Link
When using multiple X-Rack mixers together, the solo systems can be linked.This Solo Link is
compatible with the XR-20 and XR-24 Rack mixers. A 5-pin, shielded DIN cable, wired pin-to-
pin, can be used to link the Solo Audio and control signals between mixers.The “Slave” mixer
has its own solo’d signals appear in its own solo system, but these signals are also passed to
the “Master” mixer where they also show up in the Master mixer solo system, added to any
existing solo’d signals, or triggering the Master solo if nothing else was present.The Master and
Slave consoles are designated by the IN-to-OUT relationship between the Solo Link connec-
tors.The Master mixer should have the DIN cable plugged into the IN jack, the other end of
the cable should plug into the Slave’s OUT jack.
This linking can extend to additional mixers (no practical limit). Just keep plugging additional
DIN cables between the added mixers.The daisy-chain continues, the ultimate Master will be
the mixer with only one DIN cable plugged into the Link-IN jack.
NOTE 1:You should not plug the ends of the link-cable into both Link-IN jacks or both Link-
OUT jacks across two mixers. No permanent damage will result, but there may be erratic solo
behavior (besides, it’s not a nice thing to do to the XRM).
NOTE 2: Even though the DIN connector is the same type as used in MIDI systems, the Link
connection is not MIDI and should not be connected to a MIDI device.
Audio Linking
The XRM is equipped with bus-in jacks on all the main mix buses (see earlier Rear-Panel detail) allow-
ing the user to create a larger console out of multiple XRM, XR-20/24 or combinations of all types.
Similar to the Solo-Link description,“Slave” mixers can be fed to “Master” mixers by using standard,
shielded XLR cables to tie the Slave balanced outputs to the Master mixer’s bus inputs.The Slave out-
puts (still controlled by their our master faders) are fed to the Master mixer as a sub-mix. No addi-
tional inputs are taken up, the bus inputs allow for easy expansion.
AC Input
The XRM uses an internal switching power supply which is capable of accepting a wide range of line
voltages.This industry-standard IEC connector will mate up with any of the common IEC line cords.
The incoming voltage can be anywhere between 100 and 240 volts, +/- 10%.The AC mains frequency
can be 50 Hz or 60 Hz.
Connector Pinout detail
The rear panel of the XRM is screened with the pinout and electrical details of the I/O connectors. It
is reprinted here for your reference.
XRM Internal Options
The Input Channels have various options that can be selected. If specified at time of order, the factory
will set-up the XRM with the user’s desired settings. If configured from the factory, the appropriate
check-box will be marked, showing which option was changed, and what it was changed to.
Mix 1-4 PRE: This PRE source is normally Pre-fader. It can be changed to Pre-Insert or Pre-EQ
PRE-Follow Mute: Normally, the PRE signal (no matter what the source) will be muted when the
main channel is muted (MUTE sw depressed).An option allows the PRE source to ignore the channel
mute and be active (ON) at all times.
