FRONT PANEL - CONTROLS AND FUNCTIONS CONT.
of the signal is sent to the left and right output level. For true stereo imaging, maintain the knob in the
12 o’ clock position.
11. BNC JACK -
This jack is used to supply a 12V DC signal to a gooseneck light, such as the
American Audio
®
GNL-14.
12. POWER SWITCH -
This is the main power ON/OFF button. A blue LED next to the power switch
will glow when power is ON. Before you turn the power on be sure you have made all connections to the
mixer. Also be sure you amplifiers are turned off. Remember mixer on first and turned off last.
13. WIDTH CONTROL -
This knob is used to control the amount of SRS 3D process is applied to the
output source signal.
14. 3D ST CONTROL -
This button is used to activate the SRS
®
(Sound Retrieval System
®
) 3D Stereo
Process. SRS retrieves the spatial information from recordings and restores the original three-dimen-
sional 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. A microphone does not possess the
ability to interpret the direction a sound is coming from in the same way that the human ear does. How-
ever, when the audio source is recorded, directional audio cues are still present in the recording. 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.
15. TRU BASS CONTROL -
This button is used to activate the SRS
®
(Sound Retrieval System
®
) TRU
BASS™ Process. TruBass circuity actively monitors the low-frequency content of an audio signal and
optimizes the frequency and amplitude spectrum of the output signal to enhance bass perception.
Whether you are limited by space, cost or implementation, for bass previously believed impossible.
This process creates deep, rich bass in headphones and speaker systems that have poor or little bass
response. Sub-woofer performance will be enhanced substantially. Unprecedented bass response will
virtually eliminates the need for large speakers to create low frequency fundamental tones and will in
several case eliminate the need for a sub-woofer all together. Be sure that the TRU BASS™ process
will not color the midrange or create bass not present on recordings. This process will only define any
bass present on a recording.
16. TRUE BASS LEVEL -
This knob is used to control the amount of "TRU BASS" process is applied
to the output source signal.
17. WOW CONTROL -
This button is used to activate the SRS
®
WOW Process created by SRS Labs.
The WOW™ process is a combination of 3D Stereo Process and the TRU BASS™ Process. WOW cre-
ates extraordinary enhancement to the listening experience. Ordinary stereo presents a limited spatial
presentation, and often lack-luster bass (low frequency) performance. Any sound system can deliver
an audio performance with drastically improved image size, dynamics and immersion when playing a
signal processed with WOW. Because the WOW™ effect combines the 3D Stereo™ Process and the
TRU BASS™ Process, the processing of the spatial cues surrounds the listener with a holographic
representation of the performance. In addition bass becomes deep, rich and controlled through means
that don’t require a speaker with a large woofer or cabinet size. In essence you may eliminate the need
of a separate sub-woofer.
18. AUX 4 INPUT JACK -
This Aux input is for the use of a Mp3 player, or XM or Sirius satellite radio.
Input volume will be controlled by the channel four
fader.
