Features
® Plenty of Clean Power
TX-866: 80 watts of continuous power per channel into 8 ohms with no more than 0.04% total harmonic distortion. (2 x 185 watts dynamic
power at 2 ohms)
TX-844: 60 watts of continuous power per channe!} into 8 ohms with no more than 0.08% total harmonic distortion. (2 x 155 watts dynamic
power at 2 ohms)
@ Direct Access Tuning
Instead of using the UP or DOWN tuning keys to scan through the available frequencies untill you find your station, Direct Access Tuning
lets you punch in the broadcast frequency directly using the 10 numeric keys.
For example, to select 103.5 MHz you simply press the 1, 0, 3 and 5 keys.
® Classified Memory Preset
The memory presets are divided into six classes, A through F, which you can use for different types of programs (rock, news, classical,
etc.). Or you each member of the family can have a separate class (class A for Dad, class B for Mom, class D for Junior). You can assign
each preset station to one of the classes. The tuner will give you a sample of each station, in turn, in a particular class.
@ Multiple Room Remote System
You may wish to install an optional remote sensor in another room in which you have installed an additional set of speakers. Then you
will be able to operate the TX-866 or TX-844 by remote control while listening in that room, without having to go back to the room in
which the tuner amplifier is located.
You can also install yet another sensor and purchase an optional universal remote control to operate a VCR, videodisc player, TV monitor,
and/or other AV components from other manufacturers; this too is possible from another room.

to provide some protection against voltage surges and built up static
charges. Section 810 of the National Electrical Code, ANSI/NFPA
No. 70-1984, provides information with respect to proper grounding
of the mast and supporting structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding conductors, location
of antenna-discharge unit, connectian to grounding electrodes,
and requirements for the grounding electrode. See Figure 73.1.

1. Warranty Card
The serial number is written on the rear panel of this unit. Copy
the sertal number and model number onto your warranty card
and keep it in a safe place.
2. Recording Copyright
Recording of copyrighted material for other than personai use
is illegal without permission of the copyright holder.
3. AC Fuse
The fuse is located inside the chassis and is not user serviceable.
lf power does not come on, contact your Onkyo service center.
4. Care
From time to time you should wipe off 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 or a mild
ammonia cleaner, wring it out dry, and wipe off the dirt. Fol-
lowing this, dry immediately with a clean cloth. Do not use rough

2. Transmitter Battery Insertion
Precautions when using batteries
@ The remote control transmitter is powered by two batteries.
Before using this unit for the first time, insert the two batteries
(included) as shown in the diagram.
@® Average battery life is about one year. This period may be shorter
depending on the frequency of use and environment (temper-
ature and humidity) in which the remote contro! transmitter is
used.
Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit
is unplugged. The unit must be plugged in and the power switch
turned on and off once tn order to charge the back-up system.
Note that since this is not a permanent memory, the power switch
must be turned on and off a few times each month to keep the
back-up system operative.
The memory preservation period after power has been turned
off varies depending on climate and placement of the unit. On
the average, memory contents are protected over a period of a
few weeks after the last time power has been turned off. This
period is shorter when the unit is exposed to a highly humid
climate.

FM Antenna Connections
Use the T-shaped antenna if you live in an area where signal strength
of FM broadcasts is high. Connect the antenna to the FM 300 ohms
terminals and place the antenna on a wall or other surface in the
position in which reception is best. If signal strength ts low in your
area, use a multi-element FM outdoor antenna and connect to this
unit using a 75 ohm coaxial cable because this type of cable is
more resistant to interference than 300 ohm cable. Consult your
Onkyo authorized service center about the right type of antenna
for your area.
Directional linkage
type splitter
NOTE:
To receiver
To TV (or VCR)
Do not use the same antenna for both FM and TV (or VCR)
reception since the FM and TV (or VCR) signals can interfere
with each other. If you must use a common FM/TV (or VCR)
antenna, use a directional linkage type splitter.

AM Antenna Connections
An AM loop antenna is included in the installation instructions bag.
Take out the connection jine and connect it to the AM antenna
terminals. This loop antenna can be placed on top of any stable
surface or attached to a wall. Try several positions to determine
which gives the best reception. Be sure the antenna is not near a
speaker, power cord, television set, VCR, or motorized appliances.
When using an external AM antenna, do not remove the loop an-
tenna: connect both antennas to the AM antenna terminals.

need to be connected.
1. Place the turntable on a firm shelf or deck free from vibrations
(especially those generated by the speaker system). If the
turntable is permitted to pick up such unwanted vibrations, not
only with the performance of the unit drop, but distortion in the
bass frequencies and howling In the speakers may also occur.
2. Check the turntable instruction manual for any other precautions.
3. The loud noises that occur when connecting and disconnecting
the turntable leads, replacing the cartridge or lowering the
tonearm could damage the speakers. Always turn the power
switch off before making connections.
4. If an Onkyo turntable with remote control jack is used with this
unit, the remote control transmitter can also be used to start and
stop turntable operation. In this case, the turntable and
TX-866/844 must be connected with a remote control cable.
Insert the plug into the PHONO jack of the REMOTE CONTROL
on the rear panel of the TX-866/844. (Please refer to “Con-
nections for Remote Control on page 6.)

Connections for Multiple Room Remote Control
Multiple Room Remote System ({MTFR)
The Onkyo HR-10 Remote Sensor (sold separately) greatly
increases system flexibility. Used with your TX-844 or TX-866,
the HR-10 allows you to control speakers even when you are
not in the same room as the TX-844 or TX-866. In addition to
basic functions like speaker on-off and volume, you can also
control most Onkyo CD Players and Cassette Decks that use the
fRl (Remote Interactive) system. Adding an HE-50AC Remote
Emitter (also available as an option) allows you to control even
the non-Onkyo components in your home entertainment system
from a separate room. The HR-10/HE-50AC combination also
works when the components are behind the closed doors of an
equipment rack or wall unit.

Remote sensor and emitter (like the HR-10 and HE-50AC) should
be connected with low capacitance shielded two coaxial cable
with mini-plug .136" (%"} (3.5mm) diameter connectors.
Maximum cable length is determined by the characteristics of
the particular cable used but approximately 164’ (50m) lengths
are generally practical. Ready made cable complete with
mini-plug connectors are available in the following lengths: 61%’
(2m) (HW-2), 9876’ (30m) (HW-30), and 164’ (50m) {HW-50). We
also offer HR-10W. (HR-10W is a single-packed system attached
the HW-30 with the HR-10.) Contact your Onkyo dealer or service
center for details. .
(Speaker connections, especially for those in another rooms,
should be made with heavy duty speaker cable. Conventional
18 gauge “zip cord,’ while generally suitable for
speaker/amplifier connections within the main room, may not
be sufficient for tong inter-room runs. Onkyo recommends 16
or 14 gauge stranded wire for these installations.)
(When speakers are connected to B)
When the HE-50AC its being used to control more than one
device from a distance but the infrared beams from the HE-50AC
remote control transmitter alone will not reach these devices
connect an HE-10 (remote emitter head) to the HE-50AC, and
set it up to be aimed at the devices to be controlled. The HW-2
cable 6%' (2m) is attached with the HE-10. Up to three HE-10
units can be used with this equipment.

Using the remote control transmitter
1. Remove the batteries if the remote control transmitter isnot going
to be used for a long time.
2. The batteries of the remote control transmitter must be replaced
periodically.
3. This unit uses infrared rays. Therefore, commands may not be
received properly if the front panel of this unit ts exposed to
bright light. To prevent this from occurring, place this unit so
that it is not dtrectly exposed to bright light.
4. lf this unit is placed inside an audio rack behind a glass door,
the door should not have colored giass or have any decorations
on it, since this could shorten the range or prevent commands
from being received.
5. Use of other infrared remote contro! devices in the same room
may cause interference.
6. The transmitter operates up to a distance of about five meters
(16 feet). The transmitting window must always be pointed at
the reception window when a command is sent to the
TX-866/844.
7. If this remote control transmitter does not operate properly,
confirm that the batteries are not dead. If the problem persists,
contact your Onkyo Service Center.
