larly on music-oriented formats. Although not the loudest 9200 preset, it has a smooth,
well-balanced quality that keeps audiences listening. We tuned it to sound very similar to
the legendary Gregg Laboratories 2540 AM processor (designed by Orban's Vice Presi-
dent of New Product Development, Greg Ogonowski, in the 1980s), using a direct A/B
comparison with the Gregg processor to ensure accuracy. This required setting the

The
PRESENCE
is a very loud preset, particularly useful for talk formats. Unlike the "HF" presets, it is set
for full NRSC bandwidth and tuned for a moderate amount of bass (although the actual
audio cutoff frequency will depend, as always, on the setting of the bandwidth control in
System Setup). MW stations seeking to increase their coverage and to cut through co-
channel interference are appropriate candidates for this preset, which renders speech
crisp, loud, and highly intelligible.
This preset is targeted for the typical narrowband radio and will sound shrill and unpleas-
ant on wideband radios (of which there are very few in the market). If you feel that the
preset has too much distortion, feel free to turn it down it with

without seriously compromising loudness and coverage.
You can also reduce the midrange boost if you feel this is excessive. Part of the boost is
implemented in the Equalization section and part is implemented by the B4 and B5 out-
put band mix controls, which are found in the Expert controls.

New User Control

B1/B2 XO sets the Band 1 / Band 2 crossover (in the multiband compressor) to 150 Hz
(as in earlier software versions) or 200 Hz. This control affects the dynamic mid-bass bal-
ance. When set to 200 Hz, it emphasizes low bass and slightly reduces mid-bass by com-
parison to the 150 Hz setting. We added the control to allow us to emulate the sound of
the analog Gregg Laboratories processor as closely as possible. This control is found in
Full Control and Expert Control.

Ethernet Support

Version 3.0 of 9200 PC Remote software has been completely rewritten to improve its
connection reliability. We have also added support for the Lantronix® UDS-10 and
UDS100 Device Servers, which are small, inexpensive Ethernet-to-serial interfaces.
These allow you to remote control your 9200 from your LAN, WAN, or over the Internet
via TCP/IP.
Please see the 9200 PC Remote V3.0 Operating Manual for full instructions on how to
implement Ethernet support.
