Notes on Audio Output
The receiver has an “Audio Amplifier” switch with “Normal” and “Boost” settings.
For a smaller rooms use the “Normal” setting; for larger rooms use the “Boost”
setting.
This is used to normalize the loudness LED bar display, so in a small room where
you never would set the sound volume too loud, with the “Normal” setting the LED
bar display would not be all the way to the bottom all of the time! Also note that if
you use 4 Ohm speakers, the power output from the system is maximized, so if
you are using 8 Ohm speakers, and in “Boost” you still don’t have sufficient
loudness, then you can switch to a lower impedance speaker such as 6 or 4 Ohm
to increase the loudness.
You can add more than one speaker to each of the Left or Right output of the unit.
If you are using 8 or 16 Ohm speakers, you can parallel 2 of them on each channel
(for a total of 4 speakers). If you are using 4 Ohm speakers, then you need to put 2
of them in series for each channel (for a total of 4 speakers).
The VSA-31-R receiver has a Line-level audio output. This connector is used in
cases where the built-in power amp may not be sufficient. Upon connecting a plug
to this jack, the power amp outputs are disabled and you can route a stereo cable
to any external Audio Amp of your choosing. Contact Hall Research if
simultaneous audio from the 3.5mm and the External amplifier are needed at the
same time. The volume knob on the sender still acts on the level of the line output
signal.
Notes on Video Compensation Adjustment
The A/V signal from the remote Cat5 UVA sender has a video compensation pot
accessible at the front of the VSA-32-CP control panel. Turning the pot
CLOCKWISE (CW) increases the compensation; turning the pot
COUNTERCLOCKWISE (CCW) decreases the compensation. Start with the pot
turned fully CCW and adjust the compensation until the picture has reached
optimal quality for the length of cable being used.
