The ES-2940 is a single rack mounted unit which contains two Audio Distribution Amplifiers, two Video Distribution Amplifiers and a five output RS-170A Black Burst Sync Generator (BBSG). The unit is designed to meet the requirements of systems which must interface with, distribute and synchronize video and audio signals.
Each of the two 1 x 4 Video DA's provide a loop-thru input and four isolated outputs. Screwdriver adjustable Gain and EQ controls are accessible on the front panel, all inputs and outputs are provided on rear mounted BNC connectors. Both 1 x 4 Audio DA's accept one balanced (or unbalanced) audio signal and produce four identical copies. Each of the totally isolated outputs has its own front panel-mounted Gain control (an adjustable, internally mounted input attenuator is also provided). The audio inputs and outputs are accessible on rear mounted terminal blocks. If unbalanced outputs are desired, then each of the 1 x 4 Audio Distribution Amplifiers can provide up to eight separate and isolated feeds. The BBSG provides a convenient source of composite black burst for pre-blacking video tape or for general synchronization purposes. The output signal consists of sync, blanking, reference black setup level and colorburst which is SCH phased. The five RS-170A outputs are provided on rear mounted BNC connectors.
