or has been dropped.
• Make sure to connect the protective grounding to
prevent any electric shock before turning ON the
apparatus.
• The external wiring connected to the output hazardous
live terminals requires installation by an instructed
person, or the use of ready-made leads or cords.

authorities.
• By disposing of electrical and electronic equipment
correctly you help to save valuable resources and
prevent any potential negative effects on human health
and the environment.
• Improper disposal of waste electrical and electronic
equipment can have serious effect on the environment
and human health because of the presence of hazardous
substances in this type of equipment.
• The waste electrical and
electronic equipment (WEEE)
symbol, which show a bin that has

ABOUT THIS MANUAL
This manual is composed of five main sections:
“SAFET PRECAUTION” in which there are safety
information and instructions; “CONTENTS” with the
table of contents; “INTRODUCTION” a brief
description to introduce you in the use of apparatus;
“INSTRUCTION” with technical information
concerning installation and usage; “TECHINICAL
DATA” with technical specifics.
Each section name is printed on the top side of the
manual.
LEGAL DISCLAIMER
AUDEIA, RSS, AASER and the other names of
apparatus or components are trademarks or
registered trademarks of respective owner.
No part of this manual may be reproduced or copied
without write permission of AUDEIA.
AASER technology is world patented solution.
Technical specification and appearance are subject to
change without notice.
PRECAUTION FOR INSTALLATION AND USE
• The operating temperature should be between
4°C and 36°C
• To prevent degrade of sound quality and
malfunction do not install in places with
significant vibration, exposed to direct sunlight,
in extremely hot places, in places with high
humidity or bad ventilation, places exposed to
rain or other water.
• Do not place anything on the unit
• Do not expose to fast reduction of temperature

INSTRUCTION
AUDEIA - AM004 /x – USER MANUAL – EN 5
OVERVIEW
The AM004 /X is a 2/4 power amplifier, it has
separated connection to use it as 2 channels or 4
channels amplifier. It could be used also as 2 ohm 2
channels amplifier, paring the channels (PTL - Parallel
Tied Load). The system has balanced inputs with XLR
connectors and speakon connector for power outputs.
Also the power supply cord is with speakon type
connector to ensure a stable connection.
FRONT PANEL
In the front panel is located:
(1) Power switch.
(2) Protection LED for channels pair, indicate that the
amplifier is in a protection state as protection for
some electrical trip. Ensure that there are not
wiring problem and restart the device.
(3) Main volume regulation, this KNOB regulates
the output level of the amplifier channels
(4) VU METER, this METER indicates the output
sound level.
(5) Normal to bridge selector, set on bridge to use
the amplifier as 2 channels and high current 2
channels mode, more info for last solution in
the PTL (Parallel Tied Load) chapter.
REAR PANEL
In the rear panel there are all the connection
interface. Following the details:
(1) The power supply inlet (speakon)
(2) 2 channel mode (bridge) output connectors,
speakon 2 pin type. To use this set the switch in the
front panel in bridge mode (see bridge mode
capter).
(3) 4 channels mode output connectors, speakon 4
pin connectors, pin 3 and 4 are required only in PTL
(Parallel Tied Load) mode.
(4) Line inputs, XLR balanced type
The power supply inlet and the power supply specifics change according to countries standards; until
to connect the AC cord to the power source please verify that the supply voltage and frequencies
printed on the rear panel are coincident with the local electrical system specifics.

INSTRUCTION
AUDEIA - AM004 /x – USER MANUAL – EN 6
CONNECTIONS
Inputs line are XLR balanced type.
The connections are according the standards,
following the details:
1 - GND
2 – Positive
3 – Negative
The powered outputs are speakon type.
In the output lines the pole 1 is the positive, the pole 2
is the negative. In the speakon of the first two
channels, channel 1 and channel 2, there are two
more pin that you have to connect together for the
PTL usage.
PTL (Parallel Tied Load)
The PTL mode let you to have 2 channels that are able
to support 2 Ohm load. For this type of configuration,
you have to make a specific wiring.
Firs of all, in the speakons of the channels 1 and 2 a
connection is required in the pin 3 and 4 to short
them together.
After that you have to connect outputs 1 and 3, and
outputs 2 and 4 in parallel as shown in the following
picture. The inputs must also be connected in parallel
in the same way.
Bridge mode
For bridged operation of one or two pairs of channels,
connect the speakers to the dedicated speakons.
On the front panel set to brd (bridge) the selector
switch for the channels involved.
