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 {ront soundstage, and surround effects and ambience emmanating from the sides and rear of the theater. These four
channels are encoded, or matrixed, into a two-channel DOLBY STEREO release, and decoded in the theater by a professional DOLBY STE-
REO MP (Motion Picture) decoder. These surround sound effects are 'hidden' in the two-channel stereo movie release, and decoded in the the-
ater by special Dolby equipment.
These same two-channel motion picture masters are used tor production of steréo VHS, VHS Hi-Fi, Bela Hi-Fi, and stereo Laser Vision discs
that you can buy or rent at your video store, The TX-SV515PRO incorporates the Dolby Pro Logic Surround Circuit, which is designed to emu-
late the audience experience found in DOLBY STEREO theaters. Like DOLBY SURROUND, DOLBY PRO LOGIC SURROUND is capable of
creating a mult-dimensional soundstage, but with the increased channel separation it gives a far greater sense of 'movement" and sound focal-
ization. Just like in the theater, the addition of the active center channel ensures that ail audience members hear dialogue coming from its on-
screen sources regardless of seating position.
Since tha TX-SV515PRO is equipped with front amplifiers, center amplifier and rear (surround) amplifiers, Dolby Pro Logic Surround and Hall
effects can all be produced, You can enjoy the feeling of a movie theater of concert hall in your own room. To reproduce thase effects, rear (sur-
round) 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 placemert for optimum sound quality in your room,

When using a video cassette tape or a video disc that have the DOLBY STEREO or DOLBY SURROUND trade mark, you can achieve the
same kind of sound in your room that you experience ina movie theater.
In the Dolby Pro Logic Surround mode, three modes are available according to the type of center speaker used.
1, Normal' When a small speaker is used on the center channel, signals of 100 Hz or more are oulput from the center speaker, and signals
of 100 Hz or less are split between the front Land R channels.
2. Wide band: When the center speaker is approximately the same size as the left and right front speakers, it operates throughout the full
frequency range.
3. Phantom; When no center speaker is used, the center channel signal is split between the front L and R speakers, producing the same
results as found with a center speaker.

Multiple Room Remote System (mR)
The ONKYO HR-10(W) Remote Sensor (sold separately) greatly increases system flexibility. Used with your TX-SV515PRO, the HR-10(W)
allows you to control speakers even when you are not in the same roorn as the TX-SV515PRO. In addition to basic functions like spaaker on-off
and volume and so on, you can aiso control most ONKYO CD Players, Cassette Decks and Digital Audio Tape Decks that use the (Remote
Interactive) system; Adding an HE-50(AC) Remote Emitter (also available as an option) allows you to control even the non-ONKYO components
in your home entertainment system from a separate room
When the HE-50(AC) is being used 'o control more than one device trom a distance but the infrared beams from the HE-50(AC) remote control
transmitter alone will not reach these devices. connect an HE-10 (remote miter head) to the HE-50(AC), and set it up to be aimed at the
devices lo be controlled The HW-2 cable 6-1/2" (2m) is attached with the HE- 10. Up to three HE-10 units car be used with this equipment.
