OPTIMOD 6300 DIGITAL

Sound is Unexpectedly Quiet

The CBS Loudness Controller and/or BS.1770 Safety Limiter may be turned on acci-
dentally. Their threshold controls are located in the M
processing preset. To defeat them, set their threshold controls to OFF.
In the factory presets, the loudness controllers are turned on in the "TV"
and "TVA" presets and are turned off in the remaining presets.

General Dissatisfaction with Subjective Sound Quality

The 6300 is a complex processor that can be adjusted for many different tastes. For
most users, the factory presets, as augmented by the gamut offered by the L
M
control for each preset, are sufficient to find a satisfactory "sound." However,
ORE
some users will not be satisfied until they have accessed other Modify Processing
controls and have adjusted the subjective setup controls in detail to their satisfac-
tion. Such users must fully understand the material in Section 3 of this manual to
achieve the best results from this exercise.
Section 1 of this manual provides a thorough discussion of system engineering con-
siderations, particularly with regard to minimizing overshoot and noise.

Problems Specific to Sound for Picture Applications

Dialog is muffled


Use the five-band structure and set the B3>B4 C
controls to a higher value. This will allow the processing to apply more dynamic
high frequency boost.

Set the B4 C
OMPRESSOR
This will produce less gain reduction in the presence region.

Try using the 6300's HF Enhancer. To do so, Locate to the E
set the HF E
NHANCE
(like 0.25) are appropriate because they minimize the possibility of increasing
noise.

Transient loudness events (like esses in speech) sound obtrusively loud


Set the L
OUDNESS
controller to do more de-essing but may decrease transient impact as a side ef-
fect.

Set the T
RANSIENT

If "ess" sounds in speech (particularly with women's voices) seem too pro-
nounced, one solution is to use the five-band structure and tune it for de-essing
(which we have done already in the TVxxx preets). Set the S
control more negative.
T
control to a higher value (i.e., closer to 0 dB).
HRESHOLD
control to taste. For most TV programming, very low settings
A
TTACK control closer to 100%. This will allow the loudness
E
NHANCE control to 0 ms.
