1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in
accordance with the manufacturer's instructions.
8. Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug
has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety.
If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete
outlet.
10. Protect the power cord from being walked on or
pinched particularly at plugs, convenience
receptacles, and the point where they exit from the
apparatus.
11. Only use attachments/accessories specified by the
manufacturer.
12. Use only with the cart, stand,
tripod, bracket, or table
specified
by
the
manufacturer, or sold with
the apparatus. When a cart is
used, use caution when
moving the cart/apparatus
combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate
normally, or has been dropped.
15. Damage Requiring Service
Unplug the apparatus 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 apparatus,
C. If the apparatus has been exposed to rain or water,
D. If the apparatus 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 apparatus to its normal operation,
E. If the apparatus has been dropped or damaged in
any way, and
F. When the apparatus exhibits a distinct change in
performance this indicates a need for service.
16. Object and Liquid Entry
Never push objects of any kind into the apparatus
through openings as they may touch dangerous
voltage points or short-out parts that could result in a
fire or electric shock.
The apparatus shall not be exposed to dripping or
splashing and no objects filled with liquids, such as
vases shall be placed on the apparatus.
Don't put candles or other burning objects on top of
this unit.
17. Batteries
Always consider the environmental issues and follow
local regulations when disposing of batteries.
18. If you install the apparatus in a built-in installation,
such as a bookcase or rack, ensure that there is
adequate ventilation.
Leave 20 cm (8") of free space at the top and sides and
10 cm (4") at the rear. The rear edge of the shelf or
board above the apparatus shall be set 10 cm (4")
away from the rear panel or wall, creating a flue-like
gap for warm air to escape.

THX Ultra2
Before any home theatre component can be THX
Ultra2 certified, it must pass a rigorous series of
quality and performance tests. Only then can a
product feature the THX Ultra2 logo, which is your
guarantee that the Home Theatre products you
purchase will give you superb performance for many
years to come. THX Ultra2 requirements define
hundreds of parameters, including power amplifier
performance, and pre amplifier performance and
operation for both digital and analog domains. THX
Ultra2 receivers also features proprietary THX
technologies which accurately translate film
soundtracks for home theater playback.

The wires in the mains lead are coloured in accordance
with the following code:
Green-and-Yellow : earth
Blue
: neutral
Brown : live
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
The wire which is coloured green and yellow must be
connected to the terminal in the plug which is marked
with the letter E or by the earth symbol
, or coloured
green or green and yellow.
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured
black.
The wire which is coloured brown must be connected to
the terminal which is marked with the letter L or coloured
red.
IMPORTANT
A 13 ampere fuse is fitted in this plug. Should the fuse
need to be replaced, please ensure that the replacement
fuse has a rating of 13 amperes and that it is approved by
ASTA or BSI to BS1362. Check for the ASTA mark or
the BSI mark on the body of the fuse.
IF THE FITTED MOULDED PLUG IS UNSUITABLE
FOR THE SOCKET OUTLET IN YOUR HOME THEN
THE FUSE SHOULD BE REMOVED AND THE PLUG
CUT OFF AND DISPOSED OF SAFELY. THERE IS A
DANGER OF SEVERE ELECTRICAL SHOCK IF THE
CUT OFF PLUG IS INSERTED INTO ANY 13
AMPERE SOCKET.
If in any doubt, please consult a qualified electrician.
CAUTION:

The fuse symbol, within an equilateral triangle on the rear
panel, is intended to alert the user to always replace the
fuse with a fuse of the same type. The "T" in T10A refers
to "time lag", the "10A" refers to a current rating of 10
amperes and "L" refers to "low breaking". The fuse type
depends on the power supply used for your model. For
details on the fuse rating, refer to "
Fuse" on page 11.
For replacing the fuse, make sure to contact your Integra/
Onkyo authorized service center or your Integra Research
dealer.

Precautions
Before using the RDA-7.1 power amplifier, be sure to
read the page above entitled Important Safety
Instructions and this page of precautions.
Power cord
The RDA-7.1 comes with a three-pronged power cord
that contains a grounding wire. To help prevent electrical
shocks, always insert all three prongs when plugging in
the power cord. If the plug of the power cord is not
properly plugged in all the way, it may lead to an
electrical shock.
Be sure to only use wall sockets that properly fit the plug
of the power cord. If the socket does not match the plug of
the power cord, you will need to prepare an adapter.
Always use an adapter that is properly certified for this
application.
WARNING:
THIS APPARATUS MUST BE EARTHED.
AC fuse
Never plug the power-supply cord while the fuses
installed on the RDA-7.1 are removed.
For replacing the fuse, make sure to contact your Integra/
Onkyo authorized service center or your Integra Research
dealer.
Speakers
Connected speakers should have an impedance of 4 ohms
or greater. If speakers with an impedance of less than 4
ohms are connected, it may damage the RDA-7.1.
Ventilation
The RDA-7.1 is a high-power amplifier, so the internal
temperature of the device rises to a high temperature.
Therefore, place the RDA-7.1 in a location where the
flow of air around the device is good. Also, do not place
objects or other system components on top of the RDA-
7.1 or block the ventilation holes in any way. This may
cause the internal temperature to rise and lead to a
malfunction or damage the internal components.
Care
From time to time you should wipe the front and rear
panels and the cabinet with a soft sloth. 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, thinners, alcohol or other
Chemical solvents or cloths since these could damage the
finish or remove the panel lettering.
Whenever performing maintenance on the RDA-7.1, any
of its supplied accessories, or any device connected to it,
do not use solvents or cleaners of any kind that are
inflammable or combustible.
Other
Below is a list of actions that you should never perform.
· Never perform a "thumb test" (checking whether
current is reaching the lead wire on the hot end of the
input by touching it with your fingers) on the ends of
the input jacks or input cables. Doing so may damage
the speakers.
· Never short-circuit an output terminal.
· Never remove the cover of the RDA-7.1.
Furthermore, never operate the RDA-7.1 when the
cover is removed for any reason.
· Never operate the RDA-7.1 in environments with
explosive gases or materials.
· Do not install the RDA-7.1 in a location within the
reach of small children.
Lightning storms
Never touch the power cord or plug of the RDA-7.1
during a lightning storm.
