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 microphones
- 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 corre-
sponding mono input channel.
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 Impact mixers include
XLR Mic inputs and 1/4” TS phone jacks. They can be
used in conjunction with various stereo devices, such as
synthesizers and keyboards. Also, by connecting a mono
signal to the left phone jack, the Impact automatically
doubles the signal over to the right channel. This is known
as jack normalizing.
5. Stereo Returns
The 1/4” TS Stereo Return inputs are for the return of
audio to the Impact mixer, processed by an external sig-
nal processor. 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.
