3-20 Operation
This step sets the center of the 5950’s gain reduction range to the level to which your studio operators peak
their program material on the studio meters. This assures that the 5950’s processing presets will operate in
their preferred range. You may adjust this level with a standard reference/line-up level tone from your studio
or with program material.
Note that in this step, you are calibrating to the normal indication of the studio meters; this is quite different
from the actual peak level.
SETTING ANALOG OUTPUT LEVELS
The next tab down displays the analog output levels. If you are using the ANALOG OUTPUT to feed your
transmitter, you can use the slider to get the peak level to within range of your modulation.
Also on the analog output is the option to use FLAT or PRE- EMPHASIZED audio.
If you are feeding a transmitter with a stereo encoder, it is best practice to defeat any pre-emphasis in the
transmitter or stereo encoder and perform pre-emphasis in the 5950 IF the audio path is linear (non
compressed). In some situations where audio needs to pass thru a codec, it is then necessary to send a FLAT
audio signal across.
Please note that there may be a loudness penalty in this situation as the peak control of pre-emphasized
audio in the transmitter or stereo encoder will not be as accurate as it would be in the 5950’s processing.
If you are using a non linear audio path, consider moving the 5950 to the transmitter site if possible. This will
restore the 5950’s peak control at the transmitter point for best peak management of your audio.
You may also switch the analog output for the following options:
x FM (no HD delay can be applied)
x FM+HD (FM audio after any delay is applied)
x Monitor (A low latency signal to feed talent headphones for an “off air” experience)
x HD (The output of the 5950’s HD audio path)
HEADPHONE
The drop down menu on the headphone control lets you choose what part of the 5950 audio path you want
to listen to.
x FM (no HD delay can be applied)
x FM+HD (FM audio after any delay is applied)
