Congratulations!!!
You have purchased one of the best, integrated Radio/TV
amplification systems available for in-vehicle use today.
* Integrates TV and Radio sound into a single system for simplicity,
enhanced performance and ease of use.
* On-board EQ and SRS functions greatly enhance sound quality from TV
system.
* System can be added to an existing Radio system, or installed as a new
system with optional cube speakers (model SP250) and subwoofers
(model SP690).
* Sound quality parameters can be adjusted for optimum matching to
vehicle interior.
Features:
* 4 x 15W main speaker outputs; 2 x 25W subwoofer outputs.
* SRS processor by SRS Labs, Inc. Unlike simple stereo systems, which
produce a flat, 2 dimensional sound field, the SRS processor recovers lost
spatial (directional) cues to reproduce a 3 dimensional sound field. This 3
dimensional sound field is more true to listening to a live performance
than a traditional playback of a stereo recording. This feature is active for
TV mode only.
* TV/Radio mode is activated via a simple 12VDC trigger line, which can
be controlled by your own switch (integrated into your dash design, for
example).
* 3 band EQ (100Hz, 1KHz, 10KHz centers), +/_ 10dB boost/cut for each
band.
* TV and Radio gain controls to match the system to your devices for
optimum performance.
* 3D field adjustment, to match size of sound field to vehicle.
* Low level and high level inputs for radio and TV for convenience.
* Mode indicator LED's on front panel.
* Sleep mode (ultra-low current draw mode) after 2 minutes with no signal
detected.
* All controls factory preset with recessed knobs. This allows for easy
adjustment, yet controls cannot be accidentally adjusted while being
handled during installation.
* Extruded Aluminum heat sink housing.
* All connections made on rear panel, all adjustments made on front panel.

SRS1000 Theater Sound Owner's Manual
Provides a Three-Dimensional Image from a
Standard Stereo Source!
Benefits:
Natural 3D sound image from any two speaker stereo system
Based on characteristics of the human hearing system for natural, non
fatiguing sound
Supports mono, stereo, and surround sound for enjoyment with any
input material.
Fully immersive sound without a discernible sweet spot, allowing
superb sound from any listening position.
60 U. S. And foreign patents issued.
About the Technology:
SRS , the Sound Retrieval System , came about after many years of
research on the psychoacoustic of sound and the dynamics of the human
hearing system. SRS retrieves the spatial information from recordings
and restores the original three-dimensional sound field. As a result, the
reproduced sound is much closer to a live performance. Like live
performances, SRS has no critical listening position (sweet spot).
Listeners can move around the room and continue to be immersed in full
three-dimensional sound.
How the Technology Works:
A microphone does not possess the ability to inter pret the direction a
sound is coming from in the same way that the human ear does. However,
when the audio source is recorded, directional audio cues are still present
in the recording. Without the proper processing of the ambient
information, traditional stereo reproduces a flat, two-dimensional sound
field.
By breaking down the stereo signal into its various signal components,
it is possible to isolate and restore these spatial cues and place them in the
proper space relative to the direct sounds, such as a soloist or dialogue.
These spatial cues are restored by the use of Head Related Transfer
Functions (HRTFs) , which process ambient sounds via patented
frequency response correction curves.
Stereo has a narrow sweet spot
SRS 3D Sound expand the stereo sweet spot

Rear panel description:
1. Radio, high level speaker input. Using the included 8 pin wire
harness, connect the speaker output of the radio to SRS1000.
Follow connection diagram on page 4. Do not use this input
simultaneously with Radio Line In.
2. TV In, High Level -- This input is to be used only with monaural
TV's (non-stereo) that do not have variable, stereo, line level out
put. If this input is used, no connection should be made to Line In,
TV. Doing so would cancel the SRS 3D effect.
3.Line in, TV--Connect to Stereo TV variable line level out put .
Do not connect any cable to the TV In ,Hi Level Jack if this input is
used .
4.Line in ,Radio--Connect to variable line output from radio (if
available). Do not connect the 8 pin harness to the SRS1000 if this
input is used.
5.Main Connection Input. Use included 16 pin wire harness to
apply power, TV mode trigger, and all speaker outputs though this
connection. Refer to page 4 for details.

Operation
Connecting the speakers
1. Speaker impedance
a) Front & rear speakers : 4 minimum
b) Subwoofer1 & Subwoofer 2 speaker: 4 minimum
2. Be sure to connect the cords between the speaker terminal and
speaker systems with the same polarities(''+'' to ''+'' ,''-'' to ''-'' ), if not,
the central sound will be weak and the effect of the different
instruments will not be clear. It will diminish the stereo effect.
3. When connecting the speakers, be sure that the wires do not stick
out from the terminals and touch other terminal or the rear panel!
4. Checking connections.
a) Be sure all connections are made correctly before applying
power to the main unit. Damage to the unit may result if not connected
properly. Refer to page 4 for connection details.
b) Check the polarity (positive and negative ) of connections and
the directivity of stereo separation (right cord to right channel
terminal)
First Time Operation
Important: Before Applying Power:
a) Set all controls on SRS1000 to mid position (slot in knob will be
vertical).
b) Be sure TV mode trigger is not active (ie: 0 VDC)
c) Be sure that TV and Radio are off
System Set-Up (Gain Matching, EQ setting, 3D Effect setting)
1) Apply power to SRS1000. Verify Radio mode by checking
Radio/TV indicators on Front Panel.
2) Turn on Radio and select a program source (a strong radio station,
CD-play, etc). Adjust radio volume to approximately 1/4 volume.
3) Adjust Radio gain control up and down until suitable level is
reached. Check level setting by exercising radio volume control from
min to max and verifying overall volume levels at the speakers.
Note: EQ and 3D effect controls are only for TV mode operation.
When in Radio mode, these controls are bypassed.
4) Now apply power to the TV mode trigger, and verify TV mode is
active by checking indicator on the Front panel.
5) Turn on the TV , and select a program source (Strong station,
VCP/DVD playing , etc).
6) Adjust TV volume to approximately 1/4 volume , and adjust TV
gain control on SRS1000 until suitable level is obtained.

7) Adjust EQ until desired sound quality is reached. This is done
by turning each of the 3 knobs under "3 Band Equalizer" on the
front panel. 100Hz is for Bass, 1 Khz is for midrange, and 10 Khz is
for Treble.
8) Adjust 3D Effect knob to match size of vehicle. This control is
to compensate for the acoustic properties of small and large
vehicles, which are very different. As a gengeral rule of thumb, the
smaller
