The Cinema Reference has two proprietary ADA modes, Stereo
Enhance and Mono Enhance. These modes are applied to two-
channel or one channel mixes respectively. These modes, when
selected have two variables, one of which is the Effect Delay. The
Effect Delay works in different ways depending on which of the two
modes are selected. 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. In the
Mono Enhance mode, used typically, for mono-only software, where
the right and left channel information are identical. In this mode, the
two channels are first mixed mono together, then the stereo enhance-
ment feature is applied, with the delay set to the left channel (after
mixing down to mono) and prior to the Pro Logic decoding. This
permits the Mono Enhance mode to deliver surround sound with
depth and feel, even though the input signal is mono and during
standard Dolby Pro Logic playback, would only provide audio out of
the center channel.
To set the desired Effect Delay setting:
1
While in the Pro Setup mode, turn the MODE knob until the
display reads EFFECT DELAY and then press the MODE
knob. The display will read EFFECT DELAY on the top
row and a delay setting on the bottom row (i.e. 0 ms).
2
Turn the MODE knob to change the delay setting in the range
from 0 to 20 ms (milliseconds). Please note, this control
option provides real-time feedback but the turning of the
Mode knob to increment through the steps is a slow pro-
cess.
3
To exit the EFFECT DELAY Setup Mode without leaving the
Pro Setup Mode, press the MODE knob. If you wish to
exit the Setup Mode completely, turn any of the knobs
other than MODE or INPUT.
Pro Setup - Effect Delay
The Cinema Reference has
two modes that are developed
exclusively by ADA. The
Stereo Enhance mode permits
quality surround sound
playback of two-channel
mixes, even if the separation
between the two channels is
minimal. The Mono Enhance
mode applies some of the
same theories of Stereo
Enhancement to mono-only
signals, again providing a full
surround sound array to a
mono only signal.
The Effect Delay sets up the
delay level between right and
left channels that makes the
surround effect of these two
modes more pronounced.
Please note, even slight
adjustment of the Effect Delay
will have an effect on how
these modes sound.
