System Receiving 6200's Output Will Not Lock

Be sure that the 6200's output sample rate is set to match the sample rate that the driven
system expects. Be sure that the 6200's output (Status Bits) control is set to
Stat Bit
match the standard expected by the driven system (either or ).

System Will Not Pass Line-Up Tones at 100% Modulation

This is normal in mode. Sine waves have a very low peak-to-average ratio by
operate
comparison to program material. The processing thus automatically reduces their peak
level to bring their average level close to that of program material, promoting a more
consistent and well-balanced sound quality.
To pass line-up tones transparently, initiate 6200's built-in bypass from the front panel:
Open the Setup Test screen and change the Mode setting to bypass . The 6200 can also
generate its own test tones: Change the setting to .
Mode tone
Both bypass and tone modes can also be initiated using the 6200's optically-isolated re-
mote interface (model 6200 OPTIMOD-DAB only), or via PC Control. Refer to Section
2, Installation for details.
System Will Not Pass Emergency Alert System ("EAS" USA
Standard) Tones at the Legally-Required Modulation Level
See "System Will Not Pass Line-Up Tones at 100% Modulation" (directly above) for an
explanation. These tones should be injected into the transmitter after the 6200, or the
6200 should be temporarily switched to bypass to pass the tones.

General Dissatisfaction with Subjective Sound Quality

The 6200 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 con-
LESS-MORE
trol for each preset, are sufficient to find a satisfactory "sound." However, 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 satisfaction. Such users must fully
understand the material in Section 3 of this manual to achieve the best results from this
exercise.

Excessively Loud Commercials (DTV Applications)

The Two-Band factory presets that use the Loudness Controller set their threshold at an
"average" level. If, in any preset, you feel that commercials are too loud by comparison
to surrounding program material, set the Loudness Controller to a lower threshold by
editing your on-air preset's control and saving it as a user preset. (Also,
LC THRESH
make sure that the preset you are using has the Loudness Controller activated!)
