Making Connections

Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical 3-pin XLR
inputs for balanced and unbalanced
signals. They can be used in conjunction
with microphones – such as professional
condenser, dynamic or ribbon microphones
- with standard XLR male connectors, and
feature low noise preamplifiers, serving
for crystal clear sound replication. The
MU1722X mixer features five standard XLR
microphone inputs, whereas the MU1822X
features a total of eight.
NB. When these inputs are used with condenser microphones, the Phantom
Power should be activated. However, when Phantom Power is engaged,
single ended (unbalanced) microphones and instruments should not be
used on the Mic inputs.
2. Line Inputs
This input accepts typical 1/4" TRS balanced or TS unbalanced
inputs, for balanced or unbalanced signals. There are various
numbers of these inputs depending which mixer you are using.
They can be used in conjunction with a wide range of line level
devices, such as keyboards, drum machines, electric guitars, and
a variety of other electric instruments.
3. Stereo Channels
The MU1722X and MU1822X also feature a few stereo channels,
thrown in for maximum flexibility. Each of these stereo channels
features two 1/4" phone jacks, for the addition of various line level
input devices, such as electronic keyboards, guitars and external
signal processors or mixers. The two of the four stereo channels
on the MU1822X also feature XLR microphone inputs, increasing
the number of possible uses for these inputs! If you wish to use a
monaural device on a stereo input, simply plug the device's 1/4"
phone jack into the left (mono) input and leave the right input
bare. The signal will be duplicated to the right due to the miracle
of jack normalizing.

4. AUX Sends
These 1/4" TS outputs may be used to connect to an external
signal processor, or even to an amplifier and speakers (depending
on your desired settings) from the mixer. The signal from the AUX
Sends is controlled by the main AUX and EFX controls (on the
face of the mixer), which obtain their signal from the AUX and EFX
controls located on each channel strip. The MU1722X features 2
AUX sends, whereas the MU1822X features a total of 3.

5. AUX Returns
These 1/4" TS inputs are for the return of audio to the MU1722X
and MU1822X mixers, processed by an external signal processor.
If really needed, they can also be used as additional inputs. The
feed from these inputs can be adjusted using the AUX Return
controls on the face of the mixer, whereas the AUX Return 2
feed is controlled by the EFX Return control. When connecting a
monaural device to the AUX Return 1 and 2 inputs, simply plug
a 1/4" phone jack into the left (mono) input, and the signal will
appear in the right as well.
NB. When any device is plugged into the mixer's corresponding AUX 2
Return inputs, the mixer's internal digital effect engine is then disabled.
6. Foot Switch Jack
This port is for the inclusion of a foot switch, used to remotely
activate and deactive the built-in Digital Effect processor.
7. Phones
This stereo output port is suited for use with headphones, allowing
monitoring of the mix. The audio level of this output is controlled
using the Control Room / Phones control.
8. 2T Record / Record Out
These outputs will accommodate RCA cables, able to be fed to
a variety of recording devices. Also included is a mini stereo jack
for the addition of recording devices such as MD players, and
even laptop computers. The Trim Control ensures you can adjust
the output level of these controls to your desired setting, allowing
greater quality recording.
9. 2T Return
These RCA inputs are used to connect the mixer with parallel
external devices, such as sub mixers or external effect processors,
receiving the processed signal from another source and feeding it
to either the Main L and R or the Phones mixing bus. Also included
are mini stereo jacks, for increased convenience and flexibility.
10. Main Out
These two 1/4" phone jacks will output the final stereo line level
signal sent from the main mixing bus. The primary purpose of these
jacks is to send the main output to external devices, which may
include power amplifiers (and in-turn, a pair of speakers), other
mixers, as well as a wide range of other possible signal processors
(Equalizers, Crossovers, etcetera).
