AM440/440D
MAKING CONNECTIONS
Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical 3-pin XLR inputs for bal-
anced and unbalanced signals. They can be used
in conjunction with microphones – such as profes-
sional condenser, dynamic or ribbon microphones -
with standard XLR male connectors, and feature low
noise preampliers, serving for crystal clear sound
replication. The AM440 and AM440D mixers feature
four standard XLR microphone inputs for your con-
venience.
NB. When these inputs are used with condenser micro-
phones, the Phantom Power should be activated. Howev-
er, 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 vari-
ous line level devices, such as keyboards, drum ma-
chines, electric guitars, and a variety of other electric
instruments.
3. Stereo Channels
The AM440 and AM440D mixer feature a few stereo
channels, thrown in for maximum exibility. Each of
these stereo channels features two 1/4” TRS phone
jacks, for the addition of various line level input de-
vices, such as electronic keyboards, guitars and
external signal processors or mixers. These Ste-
reo 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 / Effects Send
These 1/4” TS outputs may be used to connect to an
external digital effect processor, or even to an ampli-
er and speakers (depending on your desired set-
tings), to the mixer. The signal sent from these out-
puts is fed from the AUX send control on the AM440
and the Digital Effect Processor on the AM440D.
