• Equalizes up to 300m of PSF1/2 cable or equivalent.
• Balanced/unbalanced input and outputs.
• Clamped or auto dc (set by link).
• Pulse capability up to 4V.

BROADCAST VIDEO EQUALIZING DISTRIBUTION AMPLIFIER

The TTR400 Equalising Distribution Amplifier is a very versatile, compact and competitively priced unit, incorporating all the features necessary for today's system requirements.

It is designed to broadcast specification, providing six outputs as standard, with an option for twelve outputs. The unit also has a pulse capability up to 4V. The impressive specification includes the ability to equalise up to 300m of PSF1/2 cable or equivalent.

The unit can be supplied for various modes which include balanced (common mode rejection) or unbalanced inputs and outputs, and normal or inverted inputs and outputs. An internal link is used to select the clamp or auto dc facilities.

The TTR400 is supplied in Eurocard format. It is housed in a 3U rack unit which can accommodate up to fifteen six output amplifiers. If more than six outputs are required per amplifier, the number that can be accommodated in the rack unit is reduced, due to space limitations for connectors on the rear panel. If twelve outputs are required per amplifier, the number of amplifiers that can be accommodated is reduced to seven. The on-board power supply includes rectifiers and regulators allowing the power input to be either ac or dc.

The TTR400 can be mixed in the same 3U rack unit with the TTR440 Audio Distribution Amplifier.

TTR 440 - Stereo Audio Distribution Amplifier

Features

• Full Broadcast Specification.

• Ten stereo balanced outputs available.

• Ten mono balanced outputs available.

• On-board PSU.

BROADCAST STEREO AUDIO DISTRIBUTION AMPLIFIER

The TTR440 is a compact and competitively priced Eurocard based broadcast quality stereo audio distribution amplifier. It accepts one set of balanced stereo inputs and provides ten stereo outputs and ten mono outputs. It is usable as a stereo ADA or a dual mono ADA.

The inputs are electronically balanced with balanced transformer inputs available as an option. All outputs, stereo and mono, are also balanced electronically and, again, can be provided as transformer outputs as an option. The unit has independent adjustments of left, right and mono output gains on the front panel.

The TTR440 is supplied in Eurocard format fitted with a DIN41612 edge connector. In a 3U rack system, this connector mates with the ADA B.P card which brings out the input and output connections to a two part multi-pin connector system, and is therefore ideal for the pre-wiring of installations. A 3U frame can accommodate up to fifteen cards, but although ten stereo and ten mono balanced outputs are available from each card, there is insufficient space at the rear of the unit for them all to be made available. A typical arrangement is to bring out seven stereo and three mono outputs. The on-board power supply includes rectifiers and regulators allowing the power input to be either ac or dc. Normally unregulated DC is bussed across the rack connecting to each ADA B.P card.

The TTR440 can be fitted in the same 3U rack unit with TTR400 EDAs enabling video and audio systems to be mixed.

VIP 750 - Broadcast Sync and Video processor unit

Broadcast Synchroniser Video Processor,    Broadcast Sync Video Processor,    Broadcast Video,    Broadcast Processor

Features

• Three separate channels

• Control of sync amplitude, video amplitude and HF response

• Each channel locks to its video input

• Relay by-pass

BROADCAST VIDEO PROCESSOR

The VIP750 Sync and Video Processor was originally designed for use with Cable TV Head Ends, but it has a wide range of other applications.

In the case of Cable TV Head Ends, the signals from satellite channels arriving at the Head End can vary in amplitude, and in quality generally, for a number of reasons. In particular the sync pulses can be distorted and low amplitude, which could adversely affect the performance of "downstream" equipment.

To prevent this type of problem the satellite signal is fed via the VIP750, which locks on to the signal, "blanks" the original sync pulses and replaces them with regenerated and correctly shaped pulses. The VIP750 also provides separate control of video amplitude, sync amplitude and HF response.

A relay by-pass circuit is incorporated, which is activated in the event of power failure.

There are three separate Sync and Video Processors per VIP750 card. The card can be housed in a 1 U 19" rack unit, accommodating up to three cards, or in a 3U rack unit accommodating up to 14 cards and providing a possible total of 42 channels.
