Setting the Output Audio Levels
Now it’s time to make the audio output connections as appropriate for your
installation and adjust audio output levels. We’ll use the
VP‑8
iP
’s FM Mode for this
example, although the procedure is similar for all six of the
VP‑8
iP
’s processing modes.
If using the Analog outputs pre‑emphasized, navigate to the
Calibrate Input/Output
screen and select the check box for Analog Out Mode:
L/R
. Then adjust the Analog
Output
Gain control to set the correct output level.
If using the Analog outputs de‑emphasized navigate to the
Calibrate Input/Output
screen and select the check box for Analog Out Mode:
L/R de-emph
(de‑emphasized).
Then adjust the Analog Output Gain control to set the correct output level.
If using the AES Digital Outputs, connect it to the equipment being fed by the
VP‑8
iP
, navigate to the
Calibrate Input/Output
screen and adjust the Digital Output
level as appropriate. The Digital Output may be operated either pre‑emphasized or
de‑emphasized.
If using the Composite outputs associated with the rear panel BNC connectors,
connect the
VP‑8
iP
to the exciter’s MPX or baseband input connector (it’s usually a
BNC connector like on the back of
VP‑8
iP
). Then navigate to the
Calibrate Input/
Output
screen, select the check box for Analog MPX, and adjust the TX 1 and TX 2
controls to set the desired modulation levels.
A note for the techies:
When the Analog MPX output mode is selected the balanced
Analog Left/Right outputs are also transmitting composite stereo, not balanced Left/
Right audio as you might expect. If you have an exciter that provides a balanced
composite input (most do, even though the composite input is a BNC connector) the
best signal to noise performance will be obtained by using the
VP‑8
iP
’s balanced
outputs. Give us a call if you’d like to interface to your exciter using this method and
we’ll walk you through what’s involved.
Note that the control for setting the Diversity Delay (normally encountered in
HD installations) is not present in Guru.
Taking Presets
The
VP‑8
iP
arrives from the factory set to operate in its FM Mode and with that
mode’s “A Quick Start” preset selected. This preset provides a well balanced sound
and is usually a good starting point for a variety of program formats.
To select another preset (when the front panel is unlocked) simply turn the rotary
encoder until the desired preset name is displayed (the display will flash, as well as
scrolling the preset name). Then press and release the encoder wheel. The display
will briefly show TAKEN and then begin showing the new preset name. If the name
is longer than eight characters the display will scroll the name.
It’s good to remember that our preset names don’t necessarily mean that the preset
can ONLY be utilized for a format with a similar name. Please feel free to experiment
and try each preset we provide to see how it sounds on your station and in your market!
We frequently add new presets to our Wheatstone Processing website for customers
to download and play with. Presets can easily be installed into our
VP‑8
iP
using the
Preset management features of either Guru or Pro GUI (more about Pro GUI later on…).
