to check with your tech guy or the board manufacturer for advice. If you use

multiple audio codecs, you should investigate the Comrex Mix-Minus Bridge.

This will allow you to expand one Program/Audition setup to handle five

codecs or other remote audio devices. It also provides IFB (talkback) to

remote sites.

If you are using a Portable Vector or Comrex HotLine at the studio, check the

OCAL audio knob. If it is turned up, audio from the studio board will be sent

back to the board, and funny effects will result.

If you are doing a call-in talk show on the road, the remote people may

complain of hearing an echo when a caller is put on the air. With the

telephone pot down, everything is OK. The culprit is the telephone hybrid

being used to put callers on the air. Some of the remote audio is leaking

through the hybrid and mixing with the caller audio. Modern digital hybrids

do a much better job of preventing this than the older units that had to be

manually tweaked for each call. If you are using a digital hybrid and having

this problem, dig out the manual and re-do the hybrids initial setup.

Some stations do not feed regular audio back to the remote, particularly for

sports broadcasts. Instead, they send a continuous feed of the board

operators microphone out to the game. In this case, the board op must

remember to wear headphones and keep the studio speakers off. His

microphone would pick up the remote audio from the speakers, and the crew

at the game would hear themselves in delayed form.
