boost the bass according to the Input signal level.DynamIc Transient Expander (DTE), to enhance the gain for more dramatic sound

(TX<108)
.x Multiple Inputs:

Seven input terminals for full source versatility, including direct connection for CD player, two Video cassette recorders or Video disk

player to VCR (direct A/V dubbing capability), two tape recorders, tuner and turntable.

equipment, Including all inputs, all prerset stations, CD player controls, tape controls, and muting and power swnches. The ultimate
in user-convenience

High Power Output with Real Phase

The TX»108 and TX788 deliver plenty of clean power even into low impedance loads. and have lots to spare for effortless handling of
instantaneous signal peaks, making the amplifier section: truly the equal of even much more expensive integrated amps Bnih also Feature
Onkyo's excluswe Real Phase lor clear, accurate stereo Imaging and extra definition. A special "Ianhase" transformer (In addition to
the power transformer) flattens out" the charging currents in the power supply Since the currents are no longer modulated by very low
frequency input outdofrphase Signals that could muddy the sound. As an added convenience. the back panel is equipped With heavy-duty
speaker terminals, specially designed to accomodate both single and parallel banana plugs (TXJOS).

FM Antennas

The Tishaped antenna is included in the installation in
structions bag. Use the Tishaped antenna if you live in
an area where Signal strength of FM broadcasts is high.
Connect the antenna to the FM 300 ohm terminals and
place the antenna on a wall or other surface in the position
in which reception is best. If Signal strength is low in your
area, use a multi-element FM outdoor antenna and connect
to this unit using 75 ohm coaxral cable because this type
of cable is more resistant to interference than 300 ohm
cable. If the coaXial cable has an F type plug, insert it in
the 75 ohm coaxial Jack. Consult your Onkyo dealer about
the right type of antenna for your area.

NOTE;
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. lf you must use a common
FM/TV (or VCR) antenna, use a directional linkage type
splitter.

AM Antenna

An AM loop antenna is included in the installation in-
structions bag. Insert it into the holder on the rear panel.
Swing one end of the antenna away from the rear panel
to the position that gives the best reception. lf reception
is still 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 speakers, power cords, television sets,
VCR's, and motorized appliances. When using an outdoor
AM antenna, do not remove the loop antenna. Connect
both antennas to the AM antenna terminals.

ri

NOTE:
AM reception lS easily affected by television sets and
VCRs Therefore, AM reception may be poor if this unit
is placed too closed to a TV or VCR.

Speaker Connections

When connecting speakers, proper polarity is important.
Always connect the (+) terminal (red) on the amplifier to
the (+) terminal on the speaker and the (7) terminal (black)
on the amplifier to the (4) terminal on the speaker.

0 Speaker load impedance is very important. Only speaker
systems rated at 8 ohms or more should be used With
this unit, If only one pair of speakers is used, the load
impedance must be at least 4 ohms.

The frequency display will immediately stop increasing
or decreasing.

I Key Touch Tone

again to give yourself another 5 seconds.

. Placing another broadcast in the same memory channel

automatically cancels the station previously stored in

that channel.

Memory Preservation

This unit does not require memory preservation batteries A
builtrin 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 backup system.
Note that sincethis is not a permanent memory. the Power switch
must be turned on and oil a few times each month to keep the
backup system operative

The memory preservation period after power has last been turned
off varies depending on climate and placement of the unit. On
the average. memory contents are protected over a period of 3
to 4 weeks after the last time power has been turned oft This
period is shorter when the unit Is exposed to high humidity
climate.
