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.
