Features
M@ Powerful A/V Receiver with Discrete Outputs
Plenty of pristine power drives your home theater system to
perfection. In surround mode you get 60 watts per channel (8
ohms) to your front L/R and center speakers, plus 20 watts per
channel to your L/R surround speakers.
Stereo mode: 80 watts per channel (8 ohms). Discrete output
stage circuitry for all channels contributes and heavy-duty
power supplies help the TX-SV525/R excel at driving accu-
rately the most demanding low-impedance speakers.
@ Dolby Pro Logic & 4 Digital Soundfields
In addition to fully digital Dolby Pro Logic (for the most accu-
rate surround sound), your TX-SV525/R gives you a choice of
four ambience-producing DSP surround modes (Theater, Hall,
Live and Arena) so you can select the listening environment
that best suits your source and your mood.
@ IPM System
Onkvo’s Intelligent Power Management (IPM) system switches
on the TX-SV525/R and automatically selects Video-1 when
you turn on your TV. giving you instant surround sound.

Explanation
Surround system
Many motion pictures produced in the last decade have been released in “Dolby Stereo” sound, with music, dialogue, and panned effects com-
ing from the 3-channel front soundstage, and surround effects and ambience emanating from the sides and rear of the theater. These four chan-
nels are encoded, or matrixed, into a two-channel DOLBY STEREO release, and decoded in the theater by a professional DOLBY STEREO
MP (Motion Picture) decoder. These surround sound effects are “hidden” in the two-channel stereo movie release, and decoded in the theater by
special Dolby equipment.
These same two-channel motion picture masters are used for production of stereo VHS, VHS-Hi-Fi, Beta Hi-Fi, and stereo Laser Vision discs
that you can buy or rent at your video store. This unit incorporates the Digital Dolby Pro Logic Surround Circuit, which is designed to emulate
the audience experience found in DOLBY STEREO theaters. Like Dolby Surround, Dolby Pro Logic Surround is capable of creating a multi-
dimensional soundstage, but with the increased channel separation it gives a far greater sense of “movement” and sound localization. Just like in
the theater, the addition of the active Center channel ensures that all audience members hear dialogue coming from its on-screen sources regard-
less of seating position.
Since this unit is equipped with Front amplifiers, Center amplifier and Rear (Surround) amplifiers, Dolby Pro Logic Surround, Theater, Hail,
Live and Arena effects can all be produced. You can enjoy the feeling of a movie theater or concert hall in your own room. To reproduce these
effects, Rear (Surround) speakers and Center speaker are necessary. The placement of these speakers is important. You can experiment with
various positions and locations to find the best placement for optimum sound quality in your room.
DSP (Digital Signal Processor)
The DSP converts the musical signal into digital form and produces reflected sound from the digital signal. This 1s apphed to the musical signal
to yield an effect approaching that of a live performance.

Multiple Room Remote System (mR)
This remote system greatly increases system flexibility when it is used with Onkyo’s or Xantech Corporation's Multi Room system.
1. U.S.A., Canadian and Mexican models
The following concerns Xantech Corporation’s Mult: Room system.
The gray terminal on the TX-SV525 is the (TREX terminal.
Used with your TX-SV525 the XANTECH 480B-00 (DINKY LINK) or 780-10 (J-BOX RECEIVER) and 789-40 (CONNECTING
BLOCK), and 781C-00 (ACI20V POWER SUPPLY) or 782-00 (HI CURRENT POWER SUPPLY) allows you to control speakers even
when you are not in the same room as the TX-SV525. In addition to basic functions like speaker on-off and volume and so on, you can also
control most ONKYO CD players and cassette decks that use the yy system. Adding an 282-00 (MINI EMITTER) allows you to control
even the non-ONK YO components in your home entertainment system from a separate room.
When the 282-00 is being used to control more than one device from a distance but the infrared beams from the 282-00 remote control alone
will not reach these devices, connect an another 282-00 to the 789-40.
Consult your nearest Onkyo Service Center with any questions concerning Xantech Corporation’s Multi Room system.
2. Models other than U.S.A., Canadian and Mexican models
The following concerns Onkyo’s Multi Room system.
The green terminal on the TX-SV525/R is the MIRX terminal.
The ONKYO HR-10 Remote sensor greatly increases system flexibility. Used with your TX-SV525/R the HR-10 allows you to control
speakers even when you are not in the same room as the TX-SV525/R. In addition to basic functions like speaker on-off and volume and so
on, you can also control most ONKYO CD players, cassette decks and digital audio tape decks that use the gQy system. Adding an HE-50
(AC) Remote Emitter allows you to control even the non-ONK YO components in your home entertainment system from a separate room.
When the HE-50 (AC) is being used to control more than one device from a distance but the infrared beams from the HE-50 (AC) remote
control alone will not reach these devices, connect an HE-10 (Remote Emitter head) to the HE-50 (AC), and set it up to be aimed at the
devices to be controlled.
It would be necessary to change the construction of the TX-SV525/R in order to switch it from an ONKYO Multi Room system to a XAN-
TECH Multi Room system. Consult your nearest Onkyo Service Center with any questions.

Speaker placement plays an important role tn the reproduction of
sound using Surround. The manner in which the speakers are
placed varies depending on the size of the room and the wall cov-
erings used in the room. The following shows an example of a lay-
out for standard speaker placement. Refer to the example for
placing the speakers appropriately in order to experience the best
Surround sound.
In principle, for Surround sound reproduction, two Front speakers
and two Surround (Rear) speakers are required. Refer to the illus-
tration on the left.
If the Front L and R 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 is 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 amphfier. 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 Sub-
woofer can bring out the best features of Dolby Pro Logic Sur-
round.

The T-shaped FM antenna is for indoor use only. Extend the
antenna and move it in various directions until the clearest signal is
received. Fix it with push pins or similar in the position giving the
least amount of distortion.
If the reception is not very clear with the attached T-shaped FM
antenna, the use of an external antenna is recommended.
Please make sure that you comply with the following consider-
ations regarding the location.
Keep the antenna away from noise sources (neon signs, busy roads
etc.)
It is dangerous to put it close to power lines, so keep it well away
from power lines, etc.
The AM loop antenna ts for indoor use only. Set it in the direction
and position where you receive the clearest sound. Put it as far as
possible away from the main unit, TV set, speaker cables and
power cord.
When reception is not satisfactory using the attached AM loop
antenna alone, connection of an external antenna is recommended.
(Do not remove the AM loop antenna)
The external antenna will be more effective if you stretch it hori-
zontally in a high place above a window or outside.

1. XANTECH CORPORATION MULTI ROOM system (For U.S.A and Canadian models)
Consult the store where this unit was purchased or an Onkyo Service Center for information concerning the connections.
In order to use the TX-SV525 to control a CD player and cas-
sette deck, both displaying ONKYO’s fRE mark, from
another room, make the connections as shown in the illustra-
tion below.
To enable remote control operation when the TX-SV525 is
mounted in a rack which will not permit infrared beams to
pass, mount the 480B-00, 789-40 and 781C-00 outside the
rack so that the signals can be picked up.

2. ONKYO ff R system (Models other than U.S.A and Canadian models)
To enable remote control operation when this unit is mounted
in a rack which will not permit infrared beams to pass, mount
the HR-10 outside the rack so that the signals can be picked
up. If all components bear the fRI mark, connect a_ cable
from the HR-10 to the MFRXX input on this unit, and from there
connect |RRI cables to the other components (see page 9). If
the other components can receive infrared remote control sig-
nals, but do not have the (QI mark, mount an HE-S50(AC)
inside the cabinet so that signals from it will reach the sensors
in all components, and connect it to the HR-10 with an cable.
When using
the main room from another room, connect them as shown
below.
In this case, both the ONKYO CD player and the cassette tape
deck bearing the QI mark and connected to this unit can be
controlled.

A connection example using the HR-10 (optional) and HE-50 (AC) (optional) to control components in the main room from another room
is Shown below.
If all the components can not be controlled by the HE-50 (AC) alone because they are installed at various places in the main room, use a
Remote Emitter head HE-10 (optional). This also allows you to control components that are not ONK YO, or do not have an QE mark, as
long as they can be controltied by infrared remote control. When using an HE-SO(AC), the HE-S0{AC) or HE-10 shouid aiso face this unit.
Note on multiple room cables
Any remote sensors and emitters (HR-10, HE-50(AC), HE-10) should be connected with low capacitance shielded 2-wire coaxial cables
with 1/8” (3.5 mm diameter) mini-plug connectors. Maximum cable length is determined by the characteristics of the particular cables used
but up to approximately 164’ (50 m) lengths are generally practical.
Refer to the instruction manual which comes with the HR-10 when making these connections.
Sets of loudspeakers in another room should be connected to this unit in the main room with low impedance cables.

@ Master volume control knob (MASTER VOLUME)
Use this knob to adjust the volume of the Front, Main, Center, Rear (Surround) speakers.
@ Tone and balance controls
Treble, bass and selective tone are effectively only for the Front L and R speakers.
The best results are obtained from DOLBY PRO LOGIC Surround when the center and front L and R speakers contain the same amounts of
mid and high frequencies. As the treble and bass control do not affect the Center speaker, adjust the tone controls for the Front L and R
speakers to match the sound given by the Center speaker. Because of this, we recommend the use of a good quality center speaker.
