AC Fuse and Speaker Protection Fuse
The fuses are located inside the chassis and are not user
serviceable. |f power does not come on, contact your
Onkyo dealer.
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 operable.
The period of time during which memory contents are preserved
after power has last been turned off varies depending on climate
and the location and placement of the unit. On the average,
memory contents are protected over a period of 3 to 4 weeks {a
minimum of 2 weeks) after the last time power has been turned
off. This period is shorter when the unit is exposed to very high
humidity or used in an area with an extremely humid climate.

AC Outlet (SWITCHED) (USA & Canadian models only)
This outlet is switched on and off by the power switch on the
front panel. Capacity is 100 watts. Only the TX-36 is equipped
with a SWITCHED outlet. There are no AC outlets at all on
models (1TX-36 and TX-26) made for some areas.
FM Antennas
Depending on the strength and quality of FM signals in your
area, the accessory T-shaped antenna may give satisfactory
reception or you may need an external FM antenna. Connect the
lead wire from the accessory T-shaped antenna firmly to the
terminals marked ANTENNA FM 300 Ohms. Spread the antenna
ona wall, preferably outside or on the ceiling and try several
positions to determine which gives the best reception. If
reception with the T-shaped antenna is unsatisfactory, install a
multi-element external FM antenna. Consult your Onkyo dealer
about the right type for your area. Connection is made to the
FM 300 Ohms terminals by means of antenna feeder wire.
Note: 75 ohm coaxial cables are more resistant to external
interference than 300 ohm feeder cables.
AM Antenna
An AM loop antenna is attached to the rear panel of this unit.
Swing one end of the antenna away from the rear panel to the
position that gives the best reception. If reception is stil!
unsatisfactory, completely remove the loop antenna from the
rear panel and hang it on a wall or other surface in the position
that gives the best reception. Be sure the antenna is not near
speaker or power cords, televison sets, and motorized appliances.
When using an outdoor AM antenna, do not remove the joop
antenna. Connect both antennas to the AM antenna terminals.
best reception.
Speaker Connections
When connecting speakers, proper polarity is important. Always
connect the (+} terminal (red) on the amplifier to the (+)
termina! on the speaker and the (—) terminal (black) on the
amplifier to the (—) terminal on the speaker. Note that when
both the A and B speaker selectors are depressed, the A and B
speaker systems operate in a series connection. If only one pair
of speakers is connected, no sound at all will be heard.
Speaker Precautions
e Suitable speaker load impedance is important. Never use
speakers with ajoad impedance of less than 4 ohms with
the TX-36/26.
@ When using only one speaker or when you wish to listen to
monaural, the single speaker should never be connected in
parallel to both the right and left channel terminals at once.
e Do not use unnecessarily ong or extremely thin speaker
leads. If the DC resistance of the speaker leads is too high,
the damping factor will decrease.
Connecting Speaker Leads to the Speaker Terminals
1. Peel off the insulation about 15mm back from the end
of the wire.
2. When using stranded wire, twist it so that the separate wires
will not come unraveled.
3. Press the speaker termina: lever, insert the wire in the hole
and release the lever to attach each speaker lead.
4. Be sure to avoid short circuits in the speaker connections.
Tape Deck, CD Player and Other Components
Connect the output leads of the tape deck and an additional
audio component (Compact Disc player, VTR, TV, etc.) to
the TAPE PLAY and TAPE PLAY/CD jacks. Connect the input
leads of the tape deck to the TAPE REC jacks of the T X-36/26.

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.
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 will the performance of the TX-36/26
drop, but distortion in the bass frequencies and howling in
the speakers may also occur,
Check the turntable instruction manual for any other
precautions.
The loud noises that occur when connecting and
disconnecting the turntable leads could damage the speakers.

one of the preset keys, simply press the memory key
again to give yourself another 5 seconds.
6. Placing another broadcast in the same memory channel
automatically cancels the station previously stored in that
channel. For example, if a 100.1 MHz station is stored using
the first FM/AM preset key and then a 105.1 MHz station is
stored using the first FM/AM preset key again, the
100.1 MHz station will be repiaced by the 105.1 MHz
station,
Notes Concerning Memory Operation
1. Preset frequencies can be transferred to other channels. For
example, the FM station stored by preset key number 6 can
be transferred to preset key number 1 in the following
manner.

2. When the power is turned off or when the power cord is
unplugged from the wall socket, the frequencies stored in
the memory will be preserved and the last tuned station will
be returned immediately when the power is turned on again.
For example, if 90.1 MHz was tuned in when the power was
turned off, the frequency displayed when the power is turned
on again will still be 90.1 MHz.

4. Adjust the volume, tone and other controls as desired.
Tape Playback
1. Connect the output leads from the tape deck to the TAPE-1
or 2 PLAY inputs.
2. Press the TAPE-1 or TAPE-2 tape monitor switch
depending on which pair of TAPE PLAY inputs the deck is
connected to.
3. Follow tape deck operating instructions for playback.
4. Adjust the volume, tone and other controls as desired.
Tape Recording of Radio Programs or Phonograph Records
1. Make all connections between the tape deck and the unit
as shown in the System Connections Diagram.
2. Radio: Press the TUNER input selector switch [9] and
set the FM/AM selector to FM or AM.
Records: Press the PHONO input selector switch [9].
3. Put the tape deck in the recording mode. The recording can
be monitored through the speakers or headphones as desired.
Turn on the corresponding tape monitor switch to hear the
signal that, having been recorded, is returnec from the deck
to the TX-36/26 (if the deck has three heads).
Tape-to-Tape Duplicating
1. Connect two tape decks to the unit as shown in the System
Connections Diagram.
2. Load the original tape in tape deck 1 and the blank tape in
tape deck 2.
3. Press tape monitor switches 1 and 2 [8] (both indicators
light).
4, Put tape deck 1 in the playback mode and tape deck 2 in
the recording mode. Follow tape deck operating
instructions,
5. The recording can be monitored through the speakers or
headphones. If tape deck 2 has three heads, the just-recorded
signal can be monitored.
Set the proper recording level using the controls on the tape
deck used for recording. Also, during recording and dubbing
operations, never change the positions of any switches on the
TX-26/36.
e APR (Automatic Precision Reception) System
This unit is equipped with Onkyo’s unique APR system that
automatically controls the stereo/mono reception modes,
antenna input DX/local setting (TX-36 only) and FM auto
hi-blend function according to the quality (signai strength,
distortion, etc.) of the signal currently being received.
Consequently, optimum reception (the lowest distortion and
highest S/N ratio) is assured at all times.
The FM mute/mode switch {!4 should normally be left in the
ON(STEREO) (MB) position. Set to the OFF(MONO) (a:
position only to receive weak FM stations that are suppressed
by the muting circuitry. In this setting, even stereo broadcasts
will be received in the monaural made (the stereo indicator [21]
will remain off) and the APR stereo/mono selection function
will not operate. The FM tuning level switch 15] is also linked
to the APR system. Therefore, the position of this switch
determines the signal strength jevel at which APR will switch the
reception mode between stereo and mono {when the FM mute/
mode switch is in the ON(STEREO) position).
re
® Key Touch Tone (TX-36 only)
A gentie beep is emitted to confirm when a Tuning control is
used. A rear panel switch is provided to let you turn this
tone on and off as required.
