1. Read Instructions – All the safety and operating instructions
should be read before the appliance is operated.
2. Retain Instructions – The safety and operating instructions
should be retained for future reference.
3. Heed Warnings – All warnings on the appliance and in the
operating instructions should be adhered to.
4. Follow Instructions – All operating and use instructions
should be followed.
5. Cleaning – Unplug the appliance from the wall outlet before
cleaning. The appliance should be cleaned only as recommended by the manufacturer.
6. Attachments– Do not use attachments not recommended by
the appliance manufacturer as they may cause hazards.
7. Water and Moisture –Do not use the appliance near water –for
example, near a bath tub, wash bowl, kitchen sink, or laundry
tub; in a wet basement; or near a swimming pool; and the like.
8. Accessories – Do not place the appliance on an unstable cart,
stand, tripod, bracket, or table. The appliance may fall, causing
serious injury to a child or adult, and serious damage to the
appliance. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the appliance.
Any mounting of the appliance
should follow the manufacturer’s
instructions, and should use a
mounting accessory recommended
by the manufacturer.
9. An appliance and cart combination
should be moved with care. Quick
stops, excessive force, and uneven
surfaces may cause the appliance
and cart combination to overturn.
10. Ventilation – Slots and openings in the cabinet are provided
for ventilation and to ensure reliable operation of the appliance
and to protect it from overheating, and these openings must not
be blocked or covered. The openings should never be blocked
by placing the appliance on a bed, sofa, rug, or other similar
surface. The appliance should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is
provided. There should be free space of at least 20 cm (8 in.)
and an opening behind the appliance.
11. Power Sources – The appliance should be operated only from
the type of power source indicated on the marking label. If you
are not sure of the type of power supply to your home, consult
your appliance dealer or local power company.
12. Grounding or Polarization – The appliance may be equipped
with a polarized alternating current line plug (a plug having
one blade wider than the other). This plug will fit into the
power outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician
to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.

13. Power-Cord Protection – Power-supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles, and the point where
they exit from the appliance.
14. Lightning – For added protection for the appliance during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to
the appliance due to lightning and power-line surges.
15. Overloading – Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk
of fire or electric shock.
16. Object and Liquid Entry – Never push objects of any kind
into the appliance through openings as they may touch dangerous voltage points or short-out parts that could result in a fire
or electric shock. Never spill liquid of any kind on the appliance.
17. Servicing – Do not attempt to service the appliance yourself as
opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.
18. Damage Requiring Service – Unplug the appliance from the
wall outlet and refer servicing to qualified service personnel
under the following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen into the
appliance,
C. If the appliance has been exposed to rain or water,
D. If the appliance does not operate normally by following
the operating instructions. Adjust only those controls that
are covered by the operating instructions as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the appliance to its normal operation,
E. If the appliance has been dropped or damaged in any way,
and
F. When the appliance exhibits a distinct change in perfor-
mance – this indicates a need for service.
19. Replacement Parts–When replacement parts are required, be
sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as
the original part. Unauthorized substitutions may result in fire,
electric shock, or other hazards.
20. Safety Check – Upon completion of any service or repairs to the
appliance, ask the service technician to perform safety checks to
determine that the appliance is in proper operation condition.
21. Wall or Ceiling Mounting – The appliance should be mounted

Features
Precautions
WIDE RANGE AMPLIFIER TECHNOLOGY (WRAT)
WRAT virtually eliminates the adverse effects of counterelectromotive force by:
1) applying an uncommonly low amount of NFB (negative feedback),
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 ADM-2.1 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 ADM-2.1s 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 chassis and is not user-serviceable. If
the power does not come on, contact your Integra/Onkyo authorized service station.
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 chemical solvents or cloths since these could damage the finish or remove the panel lettering.
5. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME,
