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 Level. The
Effect Level is best described as throttle for the decoding circuit.
When the Effect Level is set to OFF, the decoding circuit is least
active, providing the flattest surround sound field. When the level is
set to -0 dB, the surround sound decoding circuit is processing the
audio signal at its maximum decoding level. You can decrease this
decoding level in 1 dB steps to -20 dB or also OFF. Please note, this
feature applies to both Stereo Enhance and Mono Enhance modes,
and like the Effect Level, only needs to be set once. Like all major
Cinema Reference features, you may sample the results of this set-
ting as you adjust it. Furthermore, a slight adjustment may make a
big difference in the sound you hear.. As such, this control moves
slowly. Please note, that ADA suggests a setting somewhere be-
tween -4 dB and -8 dB.
To set the desired Effect Level setting:
1
While in the Pro Setup mode, turn the MODE knob until the
display reads EFFECT LEVEL and then press the MODE
knob. The display will read EFFECT LEVEL on the top
row and a level setting on the bottom row (i.e. - 0 DB).
2
Turn the MODE knob to change the delay setting in the range
from -0 to -20 dB (decibels), or OFF. Please note, this
control option provides real-time feedback but the turning
of the Mode knob to increment through the steps is a slow
process.
3
To exit the EFFECT LEVEL 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 Level
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 Level is a unique
feature whereby you can
actually adjust the power of
the decoding circuit. Much
like a gas pedal, at -0 dB the
decoding circuit is operating
at its fullest. At -20 dB, the
decoding circuit is operating a
significantly lower rate. At
OFF, it’s features are not
noticeable at all.
