MAKING CONNECTIONS
Inputs and Outputs
1. Inputs and Outputs
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 AM1204, AM1204FX and AM1204FX USB
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,
1
single ended (unbalanced)
microphones
and
instruments should not be
used on the Mic inputs.
2. Line Inputs
This input accepts typical
2
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
AM1204, AM1204FX and AM1204FX USB 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 AM1204,
AM1204FX and AM1204FX USB 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 when the tap delay effect is chosen to adjust the
tap delay parameter. By tapping the footswitch twice, the DFX
processor will calculate the time between the two taps and use
this as the tap delay time. When tapped multiple times, only the
last two taps will be considered.
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.
