Features
M@ Your Power Needs Are Covered
A solid 60 watts per channel into 8 ohms gives you plenty of
power to drive your stereo-channel music sources to perfection
(CD, tape, phono, etc). In surround mode you get 50 watts to
each of the front three speakers — for distinctly clear center-
channel dialogue — plus 15 watts per channel to your surround
speakers — for spine-tingling, realistic wrap-around movie
excitement that’s as good as it gets.
@ Dolby® Pro Logic and Hall Surround
No doubt you want the most accurate decoding for the most
satisfying viewing and listening experience. Dolby Pro Logic
and Hall Surround fill the bill. Dolby Pro Logic Surround locks
the dialogue to the screen for heightened realism and natural,
easy-to-understand dialogue — even during raucous action
scenes. Onkyo’s Hall Surround, with adjustable digital delay,
enables you to recreate the acoustics of some of the best music
halls in the world.
@ Discrete Output Stage Circuitry
Go ahead and hook up those big, imposing, low-impedance
speakers. Then turn your system up. Loud. And enjoy the ease,
grace and effortless dynamics that Onkyo’s discrete output
stage circuitry provides. Coupled with heavy-duty power sup-
plies and properly designed heat sinks, the TX-SV424’s dis-
crete output circuitry helps it excel at accurately driving even
the most demanding low-impedance loads.
M@ Dedicated Line-Level Subwoofer Output
Big-bass impact is what separates a good home theater system
from a killer home theater system. That’s why there’s a sub-
woofer output. It gives you quick, easy subwoofer connection.
So you can have deep wall-shaking, bone-rattling bass that will
rivet you and your audience to your seats.
BM Ri Compatible Remote Control
As you might expect, the full-function § (Remote Interac-
tive) remote control gives you command of the major functions
of virtually any Onkyo component that bears the RE symbol.
@ Useful Extras You’ll Enjoy
e 2 Video and 6 audio inputs: For all your present and future
AV needs.
e 30 FM/AM random presets: Especially convenient if there
are a lot of radio stations in your area. You can assign a num-
ber, in any order, to each of your favorite FM and AM sta-
tions then access them simply at the touch of a button.
e Auto tuning: Scans your preset stations at the touch of a
button.
e 3 Station-group presets: Lets you put your favorite stations

@ IMPORTANT: The wires in the mains lead are coloured in
accordance with the following code:
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 termi-
nals in your plug, proceed as follows:
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 termi-
nal which is marked with the letter L or coloured red.
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 order to charge the
back-up system.
The memory preservation period after the unit has been
unplugged 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 the unit has been
unplugged. This period is shorter when the unit is exposed to a
highly humid climate.

Connect the output leads of the turntable to
the PHONO input jacks.
Be sure to connect the ground (earth) lead
wire from the turntable to the ground ter-
minal (GND). Turntables not provided
with ground wires do not need to be con-
nected in this way.
Place the turntable on a firm shelf or deck
free from vibrations (especially those gen-
erated by the speaker system). If the turnta-
ble can pick up such unwanted vibrations,
not only will the performance of the unit
drop, but distortion in the bass frequencies
and howling in the speakers may also
occur.

Connecting Onkyo components for RI operation
When Onkyo products with the RI (Remote Interactive) mark are connected to the TX-SV424, you are able to operate each component
with the remote control of the TX-SV424. This means you can control your whole system with just one remote control.
(The RE mark is an Onkyo mark.)
When connecting Onkyo products, it is
necessary to attach the (RE cable to be able
to use the remote control of the TX-SV424
{0 contro] the entire system.
|. To use the TX-SV424 with an Onkyo
compact disc player and cassette tape
deck bearing the (RI mark, connect the
components together using FRI remote
control cable, plugged into the REMOTE
CONTROL jacks.
2. As the exact connection sequence of the
FRI cable is unimportant. you can con-
nect from this unit to either the compact
disc player or the cassette tape deck.
3. To operate correctly, the remote control
must face towards the remote control
sensor of this unit.

Dolby Pro Logic Surround
Surround system
Since the TX-SV424 is equipped with a front amplifier, center amplifier and a rear (surround) amplifier, Dolby Pro Logic Surround effects
can all be produced. When you using video cassette tapes or video discs that have the DOLBY STEREO or DOLBY SURROUND trade
mark, you can enjoy the feeling of a movie theater in your own room. When reproducing these effects, placement of the rear (surround)
speakers is important for optimum sound quality in your room.

Speaker placement plays an important role
in the reproduction of sound using Sur-
round. The manner in which the speakers
are placed varies depending on the size of
the room and the wall coverings used in the
room. The following shows an example of
a layout for standard speaker placement.
Refer to the example for placing the speak-
ers appropriately in order to experience the
best Surround sound.
In principle, for Surround sound reproduc-
tion, two Front speakers and two Surround
(Rear) speakers are required. Refer to the
illustration on the left.
If the Front left and mght speakers are
placed too far away from each other, sound
spreads out too much and is dispersed
resulting in diminished sound quality.
To enjoy Surround sound, a Center speaker
is required in addition to the four basic
speakers.
If a screen with a projector is used, place
the Center speaker under the screen. If a
Monitor TV 1s used, it is recommended that
the Center speaker be placed on top of or
under the Monitor.
To bring out the feeling of shifting sound,
the rear speakers should not be placed on
the floor, but would be most effective
placed above ear position. They can also be
placed facing the ceiling or walls to reflect
the sound.
To enjoy powerful bass sounds, install a
subwoofer with a built-in power amplifier.
The placement of the Subwoofer does not
affect the final quality of the sound image
too much, therefore as its exact placement
is not critical, you can install it more with
the room layout in mind. To especially
enjoy A/V Surround, a Subwoofer can
bring out the best features of Dolby Pro
Logic Surround.
