L–R (Stereo Difference Channel) Will Not Null With Monophonic Input

General Dissatisfaction with Subjective Sound Quality

Security Passcode Lost (When Unit is Locked Out)

Connection Issues between the 8300 and a PC, Modem, or Net-
work
This problem is often caused by relative phase shifts between the left and right
channels prior to the 8300's input. This will cause innocuous linear crosstalk between
the stereo main and subchannels. Such crosstalk does not cause subjective quality
problems unless it is very severe.
The 8300 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
control 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 satisfac-
tion. Such users must fully understand the material in Section 3 of this manual to
achieve the best results from this exercise.
By comparison to competitive processors, the 8300 offers a uniquely favorable set of
trade-offs between loudness, brightness, distortion, and build-up of program den-
sity. If your radio station does not seem to be competitive with others in your mar-
ket, the cause is usually source material (including excess use of lossy digital com-
pression), overshoot in the transmission link (including the FM exciter) following the
8300, or an inaccurate modulation monitor that is causing you to under-modulate
the carrier. A station may suffer from any combination of these problems, and they
can have a remarkable effect on the overall competitiveness of a station's sound.
Section 1 of this manual provides a thorough discussion of system engineering con-
siderations, particularly with regard to minimizing overshoot and noise.


User Interface Slowdown: The more user presets you make, the more slowly
the 8300 will respond to front-panel commands. Delete any user presets you do
not need.

Quick Setup: On the Station ID screen (Quick Setup 9): Use Escape in place of
Cancel. The Cancel button will not work.

Software Updates: Close any running Windows programs before attempting
to update.

Interrupted Software Updates: If you canceled an update before it com-
pleted, wait at least one minute before attempting your next update.
