Precautions
WIDE KANGE AMPLIFIER TECHNOLOGY (VVRAT)
WRAT virtually eliminates the adverse effects of cotinterelectromoiive force by:
1) applying an uncommonly low amount of NEB (negative feed
back),
2) using carefully selected, high-tolerance, wide range parts in all
critical sections, and
3) incorporating innovative circuit topology based upon decades
of high-end amplifier design experience — the final result is flat
response beyond 100 kHz.
AUTO POWER ON/OFF FUNCTION
You can turn on and off the M-282 via a signal input to the AUDIO
IN jacks or 12V TRIGGER IN jack.
AUDIO IN/OUT LINK FUNCTION
The signal inputs from the AUDIO IN jacks are output from the
AUDIO OUT jacks. When used as a 2 channel amplifier in a multi
room configuration, you can connect several M-282s to enjoy the
same source in several rooms.
1. Warranty Claim
You can find the serial number on the rear panel of this unit. In
case of warranty claim, please report this number.
2. Recording Copyright
Recording of copyrighted material for other than personal use is
illegal without permission of the copyright holder.
3. AC Fuse
The fuse is located inside the chassi.s and is not user-serviceable. If the
power does not come on, conttict your Onkyo authorized service sta
tion.
4. Care
From time to time you should wipe the front and rear panels and
the cabinet with a soft cloth. For heavier dirt, dampen a soft cloth
in a weak solution of mild detergent and water, wring it out dry,
and wipe off the dirt. Following this, dry immediately with a clean
cloth. Do not use rough material, thinner, alcohol or other chemi
cal solvents or cloths since these could damage the finish or re
move the panel lettering.
5. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME,
READ THE FOLLOWING,SECTION CAREFULLY.
The voltage of the available power supply differs according to
country or region. Be sure that the power supply voltage of the
tirea where this unit will be used meets the required voltage (e.g.,
AC 120 V, 60 Hz) written on the rear panel.
Supplied accessory
Check that the following accessory is supplied with the M-282.

Rear panel facilities and connections
Caution:
• Be sure to always refer to the instructions that came with the
component that you are connecting.
• Do not plug in the power cord until all connections have been
made.
• Do not make connections to input or output jacks while the
M-282 is turned on.
• Always turn the volume of the control amplifier or
preamplifier down before turning on the M-282.
• For input and output jacks, red connectors (marked R) are used
for the right channel and white connectors (marked L) are used
for the left channel.

Use this GND terminal for connecting the ground (or earth) wire
of other component if humming noise is heard.
GND
AUDIO IN/OUT
These are the analog audio inputs and outputs. Use an RCA-type
audio connection cable to connect the output jacks of the device to
the AUDIO IN jacks on the M-282. When connecting a control
amplifier or preamplifier, connect the PRE OUT jacks to the
AUDIO IN jacks.
If you connect the AUDIO OUT jacks of the M-282 to the AUDIO
IN jacks of another M-282, the signal input at the AUDIO IN jacks
of the M-282 is also output from the AUDIO OUT jacks (Audio
In/Out Link Function).
If you set the TRIGGER switch to AUDIO, the power of the
connected M-282 turns on automatically when an audio signal is
supplied to the AUDIO IN jacks (Auto Power On/Off Function).
TRIGGER
Set this TRIGGER switch before turning on the M-282.
To turn on the M-282 with the isignal input from the 12V
TRIGGER IN jack, set the TRIGGER switch to 12V TRIGGER.
To turn on the M-282 with the signal input from the AUDIQ IN
jack, set the TRIGGER switch to AUDIO (Auto Power On/Off
Function). If you do not use Aulp Power Function, set the
TRIGGER switch to OFF.
12V TRIGGER IN
If the connected control amplifiers or preamplifiers have a 12V
TRIGGER output jack, use 1/8-inch 2P mini-jack cable to connect
the 12V TRIGGER IN jack on the M-282. This jack works on
between 5 to 12 volts DC. When the M-282 is in the standby state
and the TRIGGER switch is set to 12V TRIGGER, you can switch
the M-282 between the on and standby states with operations at the
control amplifier or preamplifier.
INPUT LEVEL
Turn this INPUT LEVEL control to adjust the input level of the
signal from the AUDIO IN jacks. Normally, set to MAX.
Note:
When a plug is connected to the 12V TRIGGER jack, be sure to
connect the analog output jacks (or PRE OUT jacks) of the device
to the AUDIO IN jacks of the M-282. Otherwise, no sound will be
produced.
