Gain Control Range
The Gain Control Range is set by jumpers JP3 (A Channel) and JP4 (B Channel) as follows:
•
Normal — provides ± 20dB gain range (default setting)
•
Wide — pr30/-65dB gain range
Remote or Local Control
Set Jumpers JP1 (A Control) and JP6 (B Control) to select Local Control (card edge) or Remote Gain
Control for the card as follows:
•
Local — the gain is set via card edge controls RV1 and RV4 (default setting)
•
Remote — the gain is set via remote potentiometer (RV1 and RV4 will have no
effect)
Board Installation
Use the following steps to install the RSA-7806 cards in a RossGear audio distribution frame:
1. Refer to the User Manual of the RossGear frame, to ensure that the frame is properly
installed according to instructions. If this module is to be installed in any compatible
frame other than a Ross Video product, refer to the frame manufacturer’s manual for
specific instructions.
2. Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convectional cooling.
3. After selecting the desired frame installation slot, hold the RSA-7806 card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.
