Introduction
The AM-100 is a compact 4 channel, 1U high, 19” rackmountable analogue audio mixer. This analogue mixer
is perfect for integration with studio or location equipment and with its audio-follows-video feature (A+V) the
AM-100 is ideal for talk shows, 12V OB van set ups and SE-900 mixer productions.
The AM-100 has 4 x XLR Balanced audio inputs, 2 x AUX XLR Balanced inputs and 2 x XLR mixed outputs.
Input channels 1~4 can be manually switched between line or Mic level. If setting up microphones the
AM100 unit can also be set to supply 48V Phantom power too. The unit also allows for your chosen
background music to be input via the 2 AUX XLR inputs. The mixed output can then be taken directly to a
recording device or an SDI audio embedding device such as the SE-900 mixer or the DAC-7L converter.
It is possible to cascade or daisy chain several AM-100 units together. This allows more audio sources to be
added to the set up and provided at the final mixed output.
Features
•4 XLR Balanced Audio Input Channels (4 Microphones or 2 Stereo pairs)
•2 XLR Balanced AUX Audio input Channels (1 Stereo pair for background music)
•2 XLR Balanced Audio Output Channels (1 mixed Stereo pair)
•¼” TRS Stereo Jack Socket for headphone Audio Monitoring
•Audio Monitor Button for selection of source/output to be monitored by headphones
•Calibrated LED dBu Audio Level meter
•Volume control for Headphone Monitoring
•A+V Button for synchronising audio switch with a video mixers tally output
•12V OB van compatible via 4pin XLR connector

Connections & Controls
Front Panel
Power Switch
Switches the power On / Off.
Headphone
Accepts a stereo ¼” jack plug for stereo headphones. The headphone
volume is adjusted by the rotating Head phone volume control.
Headphone Volume Control
Controls Headphone volume level.
Use the Headphone section to accurately monitor any of the sources
output.
Audio LED Meters
These meters play a vital part in correctly setting the audio levels to
avoid clipping or other distortion.
The LED style Audio meters, show the signal strength at the Audio
Output. The signal they measure is determined b
y the sources
selected by the Audio Bus selectors and the levels set by the rotary
pots and faders.
Audio Monitor Button
Use the Headphone section to monitor any of the sources (CH1, CH 2,
CH3, CH4) or “Master” output. Repeated presses of the Headphone
Audio Monitor button will cycle through the monitoring choices. In
many cases, headphones may be a more useful and accurate choice
than speakers for audio monitoring.
Audio Input Source Level Controls
This section of the AM-100 controls which audio
input channel
(CH1~CH4) will be sent to the Audio Bus and its associated Fader.
This row of audio channel selection buttons has LEDs built in to show
which input channel is active. Level control for each audio input source
is via the rotary pots above each of the audio channel selection
buttons.

7
A+V
When this button is engaged or lit, the audio associated with a
selected video input source automatically follows the video through
any transition between the Main and Sub Sources. When the A+V
button is inactive, the audio sources must be switched manually. For
more information, see A+V on page 9.
AUX Audio Input
Mix input for background music
Audio mixer
These CH1~CH4 Audio Level Faders are for controlling the CH1~CH4
audio mix.
These faders correspond to the Audio Source selector buttons and
control the relative volume of each input in the master output as well
as the master output level.
MASTER
This Slider is for controlling the audio level for the Mixed audio output.

8
Rear Panel
AUX Audio Output
2 channels XLR Balanced Audio output.
AUX Audio Input
Mix input for background music or daisy chaining AM-100 units together.
To daisy chain units together take the AUDIO OUT pair from the first unit
and connect these to the AUX IN on the second unit.
AUDIO IN
The AM-100 supports four XLR Balanced Audio Input channels.
There are two kinds of switches under AUDIO IN:
LINE/MIC switch is used to set the audio as LINE in or MIC in. When
LINE in is selected please also set the 48V ON/OFF switch to OFF in
order to prevent burn-out damage to the circuit.
The 48V ON/OFF switch is for phantom power. If you want to use MIC
in, please set the LINE/MIC switch first, and then if using a Condenser
microphone turn ON the 48V ON/OFF switch. If you wish to use a
Dynamic microphone please turn OFF the 48V ON/OFF switch.
TALLY
TALLY IN socket. This supplies tally source, control output by A+V.
For more information please see the A+V (Page 9).
DC IN – 4pin XLR
DC in socket connect the supplied 12V 2.5A PSU to this socket.
Grounding Terminal
When connecting this unit to any other component, make sure that it is
properly grounded by connecting this terminal to an appropriate point.
When connecting, use the socket and be sure to use wire with a cross-
sectional area of at least 1.0 mm2.

9
A+V (Audio Follows Video)
The Audio Input Channel Level pots are the first stage in the audio signal path.
Each channel carries the audio associated with a mixers video input channel.
When the A+V button is active, the audio follows the video through a
transition. This means that when this LED is lit, only one channel of the Audio
input section (CH1, CH2, CH3, CH4) will be active at a time. When the transition is a CUT, the audio will
switch abruptly at the same time.
The A+V button should be inactive while checking level settings at the beginning of a session so that you can
select the input and adjust the initial level correctly.
Tally Input Connector (A+V feature)
Pin Assignment
The Tally output from a video mixer allows the AM-100 to automatically switch between audio sources in step
with the video mix.
D-Sub 15pin Female
The pin assignment of the Tally Connector is shown in the following table:
Audio Channel CH 1 CH 2 CH 3 CH 4
Pin 1 Pin 6 Pin 11 Pin 5
GND Pins 4, 9, 14
Audio Inputs and Levels Analogue audio comes into the AM-100 through the XLR
connectors on the rear panel (see diagram). The AM-100
supports four XLR Balanced Audio Input channels.
There are two kinds of switches next to each XLR input under AUDIO IN:
The LINE/MIC switch is used to set the audio as LINE in or MIC in. When LINE in is selected please also set
the 48V ON/OFF switch to OFF in order to prevent burn-out damage to the audio circuit/Mic*.
The 48V ON/OFF switch is for Phantom power. If you want to use MIC in, please set the LINE/MIC switch
first, and then if using a Condenser microphone* turn ON the 48V ON/OFF switch. If you wish to use a
Dynamic microphone please turn OFF the 48V ON/OFF switch.
*NOTE: Always double check the manual for the microphone being used to see what advice it gives
regarding power as some Mics have internal batteries too.

Example Cascade Set Up
It is possible to cascade or daisy chain several AM-100 units together. This allows more audio sources to be
added to the set up and provided at the final mixed output. To daisy chain units together take the AUDIO
OUT pair from the first unit and connect these to the AUX IN on the second unit. Below diagram shows 3
units connected in this way.
