Congratulations!!!
You have purchased one ofthe best, integrated Radio/TV
amplification systems available for in-vehicle use today.
* Integrates TVand Radio soundinto a singlesystem for simplicity,
enhanced performance andease of use.
* On-board EQand SRS functionsgreatly enhance soundquality from TV
system.
* System canbe added toan existing Radiosystem, or installedas a new
system with optional cube speakers (model SP250) and subwoofers
(model SP690).
* Sound qualityparameters can beadjusted for optimummatching to
vehicle interior.
Features:
* 4 x15W main speakeroutputs; 2 x25W subwoofer outputs.
* SRS processorby SRS Labs,Inc. Unlike simplestereo systems, which
produce a flat, 2 dimensional sound field, the SRS processor recovers lost
spatial (directional) cuesto reproduce a3 dimensional soundfield. This 3
dimensional sound fieldis more trueto listening toa live performance
than a traditional playback of a stereo recording. This feature is active for
TV mode only.
* TV/Radio modeis activated viaa simple 12VDCtrigger line, whichcan
be controlled by your own switch (integrated into your dash design, for
example).
* 3 bandEQ (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 fieldadjustment, to matchsize of soundfield to vehicle.
* Low leveland high levelinputs for radioand TV for convenience.
* Mode indicatorLED's on frontpanel.
* Sleep mode(ultra-low current drawmode) after 2minutes with no signal
detected.
* All controlsfactory preset withrecessed knobs. Thisallows for easy
adjustment, yet controls cannot be accidentally adjusted while being
handled during installation.
* Extruded Aluminum heat sink housing.
* All connectionsmade on rearpanel, all adjustmentsmade on frontpanel.

Benefits:
Natural 3D soundimage from anytwo speaker stereosystem
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 thepsychoacoustic of soundand the dynamicsof 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 movearound the roomand continue tobe immersed infull
three-dimensional sound.
How the TechnologyWorks:
A microphone does not possess the ability to inter pret the direction a
sound is comingfrom in thesame way thatthe human eardoes. However,
when the audio source is recorded, directional audio cues are still present
in the recording. Withoutthe proper processing of the ambient
information, traditional stereo reproduces a flat, two-dimensional sound
field.
By breaking downthe stereo signalinto its varioussignal components,
it is possible to isolate and restore these spatial cues and place them in the
proper space relativeto the directsounds, such asa soloist ordialogue.
These spatial cuesare restored bythe use ofHead Related Transfer
Functions (HRTFs) , whichprocess ambient soundsvia patented
frequency response correctioncurves.

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.

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) Turnon 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, andverify TV mode is
active by checking indicator on the Front panel.
5) Turnon 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 the vehicle, the more 3D effect is needed to simulate the
full "theater experience". For the most part, however, this
adjustment is mostly according to personal taste.
