Rear Panel Features
Tape (Line) In
The Left and Right Tape inputs are available as both 1/4” TRS and RCA jacks. Both sets of inputs can be
used simultaneously, (the signals will add together). The TRS jacks are balanced, +4 dBu inputs and the
RCA jacks are unbalanced -10 dBV inputs.
Alt Out
The Left and Right ALT (Alternate) outputs are available as both 1/4” TRS and RCA jacks. Both sets of
outputs can be used simultaneously. The TRS jacks are ground-compensated, impedance balanced, +4 dB
outputs, while the RCA jacks are unbalanced -10 dBV outputs.
Monitor Out
The Left and Right Monitor outputs are available as both 1/4” TRS and RCA jacks. Both sets of outputs
can be used simultaneously. The TRS jacks are ground-compensated, impedance balanced, +4 dB outputs,
while the RCA jacks are unbalanced -10 dBV outputs.
Solo Link
When using multiple X-Series mixers together, the solo systems can be linked. This Solo Link is also com-
patible with the X 18RM / X 20RM monitor 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 soloed 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 soloed signals, or triggering the Master
solo if nothing else was present. The Master and Slave consoles are designated by the IN-to-OUT relation-
ship between the Solo Link connectors. 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 global Master control 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.
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 X-Series mixers are 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 X 18R/20R, X 18RM / X 20RM monitor mixers or combina-
tions of all types. Similar to the Solo-Link description, “Slave” mixers can be fed to “Master” mixers by using stan-
dard, shielded audio cables to tie the Slave balanced outputs to the Master mixer’s bus inputs. The Slave outputs (still
controlled by their our master faders) are fed to the Master mixer as a sub-mix. No additional inputs are taken up,
the bus inputs allow for easy expansion.
AC Input
The X-Series mixers use an internal switching power supply which is capable of accepting a wide range of line volt-
ages. This industry-standard IEC connector will mate up with any of the common IEC line cords. The incoming volt-
age can be anywhere between 100 and 240 volts, +/- 10%. The AC mains frequency can be 50 Hz or 60 Hz.
