Turntable Connections (PHONO)
Connect the output feads of the turntable to the PHONO jacks.
Be sure to connect the ground (earth) lead wire from the turntable
to the ground terminal (GND). Lack of proper ground connection
will cause hum. Turntables not provided with GND wires do not
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.
Compact Dise Player or Other Component Connections
(CD)
Connect the output leads of the CD player or an additional audio
component to the CD jacks. An Onkyo CD player with remote control
that has the AI mark can be operated by the TX-860/840. (Please
refer to “Connections for Remote Control” on page 4.) For more
details, refer to your CD player instruction manual.
Tape Deck and Graphic Equalizer Connections (TAPE-1,
TAPE-2)
1. This unit has facilities for two tape decks. If you are using only
one tape deck, connect it to the TAPE-1 jacks. If you have two
tape decks, connect one to the TAPE-1 jacks and the other to
the TAPE-2 jacks.
2. Connect the output leads of the tape decks to the TAPE-1 and
TAPE-2 “PLAY” jacks. Connect the input leads of the tape decks
to the TAPE-1 and TAPE-2 “REC” jacks of the unit. For more
details, refer to your tape deck instruction manual.
3. To connect a graphic equalizer, too, use the TAPE-2 jacks and

nection of the remote control cable.
Video Disc Player (or Video Cassette Player) Connections
(VCR-1/VDP)
Connect the VIDEO output of the video disc player to the
TX-860/840 (VIDEO) VCR-1/VDP “PLAY” jack and the AUDIO
output to the (AUDIO) VCR-1/VDP “PLAY” jack. The VCR-1/VDP
jack is only for playback, there is no REC jack. If the audio output
from the video unit is monaural, connect to VCR-2. For more details,
refer to the video disc player instruction manual.
Video Cassette Recorder Connections (VCR-2)
1. Connect the VIDEO output of the VCR to the rear panel (VIDEO)
VCR-2 “PLAY” jack and the VIDEO input of the VCR to the rear
panel (VIDEO) VCR-2 “REC” jack. Then connect the AUDIO
output of the VCR to the (AUDIO) VCR-2 L and R “PLAY” jacks.
Finally, connect the AUDIO input of the VCR to the (AUDIO)
VCR-2 L and R “REC” jacks.
2. When using a monaural VCR (having a single audio input and
output), set the VCR-2 “MODE” switch on the rear pane! to
“MONO” and use either the R or L audio jacks. If the switch is
in the “STEREO” position, sound will be heard from only the
right or left speaker system.

4. For more details, refer to the VCR instruction manual.
TV Connections (MONITOR)
1. Connect the TV VIDEO input to the TX-860/840 MONITOR
“OUT” jack. There is no need to perform an audio conn ection
since sound will be sent directly from the TX-860/840 to the
speaker systems.
2. The TX-860/840 does not have an RF converter. Therefore, it
can be used with only a monitor TV equipped with a video input
jack.
3. Since the television set, tuner (FM/AM) section of thisu nit can
cause interference that may disrupt sound and/or picture quality,
the TV and TX-860/840 and their respective connection cabies
should be placed as far apart as possible. The use of acommon
TV/FM antenna is not recommended (see antenna section).

APR Indicators
Automatic Precision Reception System (FM Mode)
APR system is Onkyo’s unique computer-controlled system.
APR system automatically sets the RF stage gain (Distance/
Local), the NR function (OFF/ON) (TX-860 only) for reducing
noise in weak signals, the HI-BLEND function (OFF/ON) for
reducing noise in weak stereo signals, and the auto
stereo/mono reception modes to the proper settings for the
qualily of the broadcast currently being received. This indicator
changes each time the APR circuit switches between the
LOCAL/DX, NR OFF/ON, HI-BLEND OFF/ON or
AUTO/MONO to show the current APR setting. (APR system
is effective for only FM reception.)
NOTE:
@ When FM Muting/Mode button [9] is OFF (MONO), the
APR Mode selection function does not operate, and the
Stereo/Mode indicator is forced to “MONO”.
The “MONO” display lights up for FM monaural reception.
The NR indicator is only on the TX-860.
The RF MODE will indicate LOCAL when sufficient signal
is received.
FM/AM Preset Buttons (PRESET STATION) and Display
Use these buttons to recall an FM or AM station or to store a
station in the memory. When a button is pressed, the corre-
sponding preset number is displayed in digital form. Refer to
the Memory section for details.
Turning Selector Buttons ( < DOWN, UP PR)
DOWN: Press to tune in a lower frequency.
UP: Press to tune in a higher frequency.
When listening to a broadcast, pressing the UP button will
increase the FM or AM reception frequency. Pressing the
DOWN button decreases the frequencies (Manual Tuning).
If the button is pressed for longer than 0.5 seconds in AM or
FM, and then released, broadcast frequencies will change
automatically until a station is tuned in (Auto Tuning).
When either the upper or the lower end of the frequency range
is reached, the displayed frequency will automatically switch
back to the other end of the range and continue to either in-
crease or decrease as before. For example, when the DOWN
tuning selector is pressed, the frequency will decrease until
the lowest frequency is reached. The displayed frequency will
then switch back to the highest frequency and continue de-
creasing as before.
Scanning will not stop for broadcasts weak enough to be
suppressed by the muting circuit. To receive a weak FM
broadcast, set the FM Muting/Mode button [9] to the OFF
(MONO) and tune in the FM broadcast. In this case, even
stereo broadcasts will be heard in mono.

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 in 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.
