Distribution Amplifiers
ADA-970 Audio Distribution Amplifier
This two rack unit amplifier distributes up to 12 balanced audio signals. Features include:

Balanced AC coupled high impedance inputs
Up to 12 separate channels
Five balanced outputs per channel
Adjustable output levels
Internal plug-in power supply
Inputs are selectably terminated to 600 ohms with diode input over-voltage protection.

ADA-2001 Stereo/Mono/Summing Audio Distribution Amplifier

Occupying two rack units, this amplifier distributes up to ten balanced stereo audio signals. Each DA module distributes one stereo audio pair to three outputs, one mono audio signal to six outputs, or one stereo audio pair to six summed outputs (stereo to mono conversion). Other features include:

Balanced AC coupled high impedance inputs
Internal plug-in power supply
Inputs are selectably terminated to 600 ohms with diode input over-voltage protection. Maximum output levels up to +24 dBm can be specified for each channel at time of order. A redundant plug-in power supply is optionally available.

VDA-3000 Series Video Distribution Amplifiers

This series of products uses a common two rack unit frame loaded with up to ten specific function modules. The unit can be customized to suit various applications by installing any combination of the following modules:

VDA-3001 sync tip DC restoration for component video and graphics (50 MHz bandwidth)
VDA-3001-2 back porch clamping for composite video signals (50 MHz bandwidth)
VDA-3001-3 AC coupling for RF signals (50 MHz bandwidth)
VDA-3001-4 DC coupling for DC signals (50 MHz bandwidth)
VDA-3002 composite video DA for NTSC and PAL composite video signals
PDA-3003 pulse DA for video synchronizing pulses
VDD-3004 delay DA for NTSC and PAL composite video signals
All inputs are 75 ohm looped through. Each input channel has eight outputs. One plug-in power supply is standard. A redundant plug-in power supply is optionally available.

VEA-973 Video Equalization Amplifier

This unit occupies one third of a rack unit for a variety of mounting possibilities. Features:

Three input channels, two outputs per channel (ideal for RGB applications)
Optional sync tip DC restoration and differential input for common mode hum rejection
Adjustable equalization for 0 to 500 feet of 9231 type coaxial cable (bandwidth to 90 MHz)
Selectable DC coupling (without DC restoration) for non-composite signals

VEA-978 Video Equalization Amplifier
Up to eight input channels can be distibuted by this single rack unit amplifier. Other features:

Looped through inputs
Two outputs per channel
Optional sync tip DC restoration and differential input for common mode hum rejection
Adjustable equalization for 0 to 500 feet of 9231 type coaxial cable (bandwidth to 90 MHz)
Selectable DC coupling (without DC restoration) for non-composite signals
A unique power supply configuration allows two VEA-978's to be operated in tandem, doubling capacity while providing power supply redundancy.
