Pro Setup - Bass Limiter - Ada PTM-6150 Operation & Installation Manual

Pro Setup - Bass Limiter

The Cinema Reference provides you with the ability to engage a
bass limiter that operates in a range from 0 dB (decibels) to -24 dB.
The function of the bass limiter is to reduce the possibility of over-
loading the subwoofer in cases of extreme volume and/or software
that provides extremely dynamic bass information. If your subwoofer
is capable of providing a large level of bass without bottoming out,
you may not need to engage the bass limiter at all. If however, you
play your system a volume levels that on occasion will cause your
subwoofer to play distorted audio segments, you will wish to engage
the bass limiter.
The Cinema Reference's "Out Of The Box" setup has the Bass Lim-
iter set to 0 dB. To adjust the Bass Limiter setting:
1 While in the Pro Setup Mode, turn the MODE knob clock-
wise until the display reads BASS LIMITER and then press
the MODE knob. The Cinema Reference's display will
read BASS LIMITER on the top line and the second line
will read a level (i.e. 0 DB LIMIT).
2 Turn the MODE knob until the display reads the desired set-
ting for the Bass Limiter (0 to -24 dB).
3 To exit the BASS LIMITER 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.

The Cinema Reference
permits you to engage a Bass
Limiter which will prevent the
subwoofer from distorting
when playing the system at
high volume levels that the
subwoofer cannot properly
process.
To best apply this feature,
operate your home theater
system at a level slightly
louder than you would
normally play it at. Try using
software that is dynamic,
something that includes
scenes with explosions might
be appropriate. Determine if
your subwoofer is beginning
to "bottom out" or distort. If
this is the case, slowly
increase the value of the bass
limiter from 0 dB to -24 dB.
As the Cinema Reference
permits you to sample the
changes live, you can
determine the limiter setting
where the bass no longer
distorts.
