Audio Gain Adjustment – Simply use these controls to
adjust the audio volume of the remote video source. We find
that it is usually beneficial to apply some gain (about 6-
10dB) at the BVD-10 driver end and then use the Output
Level control on the BVR-10 to bring the volume back
down to your desired level. This helps improve the overall
signal-to-noise level of the audio system. The only time this
additional gain may be a problem is using professional
equipment with high (+4dBu) audio signal outputs.
Video Gain (Brightness) Adjustment – The video gain
adjustment on the BLD-10 allows matching the picture
brightness between the remote video signal and the local
sources. As you increase the video gain, the picture be-
comes brighter. Toggle between a local video source and
the remote source running through the BVD-10/BVR-10.
Turn up the Video Gain control until there is no apparent
change in picture brightness between the two sources.
Cable Compensation Adjustment – As the run length of
a Cat-5 cable is increased, the additional cable capacitance
causes a loss of picture quality. The Active-Balanced cir-
cuitry in the BVD-10 provides the means for correcting this
with the Cable Compensation control. Note that this control
is labeled in distance. Estimate approximately how long the
cable run is from the BVD-10 to the BVR-10 (no need to
be precise here) and adjust the Cable Compensation
control for that distance. It is useful to have a video test
signal or a television picture with strong vertical lines to
make the final adjustments. Set the Cable Compensation
control for minimum smearing along the vertical lines.
