MAKING CONNECTIONS
Inputs and Outputs
1.
XLR Microphone Jacks
These jacks accept typical 3-pin XLR
inputs for balanced and unbalanced
signals.
They
can
be
used
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. AM440D USB-K mixer
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.
Bluetooth Connector
T h i s U S B p o r t i s f o r t h e
connection of the included
Bluetooth dongle. This will
allow for either 1 or 2 Bluetooth
microphones to be used with
the AM440D USB-K mixer. The
first microphone will be routed
to channel 3, while the second
is routed to channel 4. LED
indicators above the USB port
will light up when a Bluetooth
microphone is connected.
4.
Stereo Channels
The AM440D USB-K mixer features a few 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 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. There
are two stereo channels on the AM440D USB-K.
5.
EFX Send
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 these outputs is fed from the Digital Effect Processor.
6.
Phones Output
This stereo output jack is suited for use with headphones,
allowing monitoring of the mix. The audio level of this output
is controlled using the Phones control located just below this
connector.

7.
Main L and R Outputs
These two ports will output the final stereo balanced line level
signal sent from the main mixing bus. The primary purpose of
these jacks is to send the main output to external devices, which
may include power amplifiers (and in-turn, a pair of speakers),
other mixers, as well as a wide range of other possible signal
processors (equalizers, crossovers, etcetera).
8.
Control Room Outputs
These two 1/4" phone jack outputs feed the signal altered by the
Control Room / Phones level control on the face of the mixer. This
output has extensive use, as it can be used to feed the signal from
the mixer to an active monitor, for the monitoring of the audio signal
from within a booth, or, alternatively, for the addition of external
signal processing devices or mixers, as well as acting as a "side
fill" output, supplying audio to indoor areas that the main speakers
do not reach.
9.
Rec Output
These outputs will accommodate RCA cables, able to be fed to
a variety of recording devices. such as MD players, and even
laptop computers, ensuring total control over recording quality.
10. 2T Return
These RCA inputs are used to connect the mixer with external
devices, such as CD, Tape and Cassette Players.

11. Power Connector
This port is for the addition of a power cable and supply, allowing
power to be supplied to the mixer. Please use the power adaptor
that is included with this mixer only.
12. USB Connector
This USB connector can be used to connect
the AM440D USB-K to any modern Windows
or Mac-based computer. Doing so will allow
users to get a stereo signal both to and from
the computer.
