MAKING CONNECTIONS
Inputs and Outputs
1. Mic Inputs
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 AM1204FX and AM1204FX USBR mixers feature
four standard XLR microphone inputs for your convenience.
NB.
When these inputs are used
with condenser microphones,
the Phantom Power should be
activated. However, when Phantom
Power button 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 or TS 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
various line level devices, such as keyboards, drum machines,
electric guitars, and a variety of other electric instruments.
3. Stereo Channels
AM1204FX and AM1204FX USBR mixers feature two stereo
channels thrown in for maximum flexibility. Each of these stereo
channels features two 1/4” TRS phone jacks, for the addition of
various line level input devices, such as electronic keyboards,
guitars and external signal processors or mixers. These stereo
channels can also be used as mono channels, where the signal
from any 1/4” phone jack plugged into the Left stereo input
will cause the signal to be duplicated to the Right input due to
the miracle of jack normalizing. This does not work in reverse,
however.
4. AUX Returns
These 1/4” TS inputs are for the return of audio to the AM1204FX
and AM1204FX USBR mixers, processed by an external signal
processor. If really needed, they can also be used as additional
stereo input channels. The feed from these inputs can be
adjusted using the AUX Return controls on the face of the mixer.
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 AUX Return 2, the mixer’s internal
digital effect engine is then disabled.
5. AUX Sends
These 1/4” TS outputs may be used to connect to an external
digital effect processor, or even to an amplifier and speakers
(depending on your desired settings), to the mixer. The signal
sent from the AUX outputs are fed from the master AUX send
controls which themselves get their signals from the individual
AUX controls on input channels.
6. Footswitch Jack
This port is for the addition of a non-latching type footswitch. This
can be used to activate the digital effect processor. Tap the foot
switch once to activate effects; tap a second time to turn them off
once again.
7. Phones Connector
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 Phones / Submix control.
8. Record Out
These outputs will accommodate RCA cables, able to be fed
to a variety of recording devices such as digital recorders, tape
recorders, and even laptop computers.
9. 2T Return
These RCA stereo inputs are used to connect the mixer with
external devices, such as tape and CD players, or even Laptop
computers, receiving a signal from another source and feeding it
to the Main L-R mixing bus.
