QUAD BYPASS - Quad Bypass is a proprietary ADA Mode that will permit you to engage your entire
speaker array (7.1) when playing a two channel source. Quad Bypass is ideal for music
playback and utilizes the entire sound field. Here, the L, C, R, SUB, LS, RS, SBL, and SBR
Output channel lamps are on and all speakers are active.
STEREO ENH - Stereo Enhance is a proprietary ADA Mode that is applied to two channel signal and
is useful for playback of source material with relatively weak stereo separation. There are two
adjustments that can be made to the Stereo Enhance mode, Effect Delay and Effect Level.
When Stereo Enhance is engaged, the Effect Delay setting (0-20 ms range) is applied to the
left channel, leaving the right channel untouched, all prior to Pro Logic decoding. The Effect
Level can best be described as the throttle for the decoding circuit. The Effect Level has a
range from -20dB to +20dB. At +20dB, the Stereo Enhance mode has its effect set to maxi-
mum where at -20dB, the effect is least present. You can sample changes to the Effect Delay
and the Effect level as they are being made. Here, the L, C, R, SUB, LS, and RS Output
channel lamps are on.
To alter the Effect Delay and Level for Stereo Enhance:
1 Select an Input label that is playing a two channel signal and press the Input knob. (You will
want to be listening to a source component as you make the following changes).
2 Turn the Mode knob until the display’s second line reads STEREO ENH and press the Mode
knob.
3 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and press
the Mode knob.
4 Turn the Mode knob so that the display’s second line reads STEREO ENHNC and press the
Mode knob.
5 The second line of the display will now read LEVEL. To alter the Effect Level settings, press
the Mode knob. To alter the Effect Delay setting skip to Step 7. To completely exit the setup
menu, turn the Volume knob.
6 Turn the Mode knob to set the Effect Level between -20dB to +20dB. Then press the Mode
knob.
7 Turn the Mode knob one click so that the display’s second line now reads DELAY and press
the Mode knob.
8 Turn the Mode knob to set the Effect Delay between 0ms and 20ms. Then press the Mode
knob.
9 To continue with other setup menu options, turn the Mode knob clockwise until the display’s
second line reads BACK TO MAIN and press the Mode knob. To completely exit the setup
menu, turn any knob other than the Mode knob.
