MAKING CONNECTIONS
CONNECTING PANEL
1. XLR Jacks
These jacks accept XLR inputs for balanced signals.
They can be used in conjunction with microphones such
as professional condenser, dynamic or ribbon micro
-
phones - with standard XLR male connectors. With low
noise preamplifiers, these inputs serve for crystal clear
sound replication.
NB.
When using an unbalanced microphone, please ensure
phantom power is switched off. However, when using condenser
microphones the phantom power should be activated.
2. Line In Jacks
These balanced inputs accept 1/4” TRS and 1/4” TS line
inputs for the addition of various music instruments –
such as keyboards, drum machines, electric guitars, as
well as a variety of other electric instruments.
3. Insert Jacks
The primary use for these TRS
phone jacks is for the addition of
external devices, such as dynamic
processors or equalizers, to the
corresponding mono input chan-
nel. This will require a Y cord that
can send and receive signals of the
mixer to and from an external processor. The tip of the
TRS jack will send the signal from the input channel, and
the ring will return the signal back to the mixer (the sleeve
is the grounding).
4. Stereo Channels
The two stereo channels on the mixers include XLR Mic
inputs and 1/4” TS phone jacks. They can be used in con
-
junction with various stereo devices, such as synthesizers
and keyboards. Also, by connecting a mono signal to the
left phone jack, the mixer automatically doubles the signal
over to the right channel. This is known as jack normal
-
izing.
5. Stereo Returns
The 1/4” TS Stereo Return inputs are for the return of au
-
dio to the mixer, processed by an external signal proces
-
sor. If really needed, they can also be used as additional
stereo inputs. The feed from these inputs can be adjusted
using the Stereo Return controls on the face of the mixer.
When connecting a monaural device to the AUX Return
inputs, simply plug a 1/4” phone jack into the left (mono)
input, and the signal will appear in the right as well.
6. Auxiliary (AUX) 1 and 2 Outputs
These balanced XLR jacks and unbalanced 1/4” TS
phone jacks are the final output of line-level signal fed
from the corresponding auxiliary send mixing buses, and
are best suited for use with external effect processors or
stage monitors. Feeding the output from the Auxiliary
outs to an amplifier - and possibly an equalizer - and then
to a floor monitor speaker allows artists to monitor their
own instruments or vocals whilst performing.
7. EFX (Effect) Sends
These 1/4” TS outputs are the final output from the EFX
send mixing bus. This feed may be used to connect to an
external digital effect processor or even to an amplifier
and speakers, depending on your desired settings.
