Telecast Fiber Systems – Adder II

The Adder II features a rack-in-a-rack scaleable design, the answer to all of your audio transport needs.

With up to 64 channels of bi-directional audio, four intercom module slots (providing up to eight intercom circuits), expanded data and GPI capabilities, outstanding signal-to-noise, mic gain and phantom power control, and industry leading latency specs, today's Adder II is an audio workhorse.

Analog to Digital Conversion
Analog modules come in rows of 16 while AES modules are in rows of 8 or 16. In this way, an AES TX can interface to an analog RX, or vice versa, thus bypassing the need for expensive D-A and A-D converters. And with ultra-low latency specs, delay is never an issue.

Customized to Fit your Needs
The Adder II is built from the ground up with 1RU frames that interface to a common backplane. You buy only the parts that you need. Analog and AES TX and RX frames can be combined with Intercom and Data frames to create an audio system that is perfectly suited to your particular application. Whether you need 64 x 64 analog audio or 32 analog to 16 AES signals in just one direction, with or without intercoms and data, the Adder II gives you maximum flexibility.

Convenience and Control
Analog TX modules feature mic preamps that allow 40dB of gain adjustments plus 12/48V phantom power via a convenient switch and LED display. The BoothPak can be optionally equipped for remote control of these functions. And with better than 25dB of optical dynamic range, this Adder can operate across the theater or across town.

The Adder II can operate on one or two fibers or two coaxial cables. Its dual redundant TX and RX are at different wavelengths to facilitate easy WDM single-fiber operation. GPI's are via convenient binder-posts, and data offerings include RS-485 for use with matrix intercom keypanels. The signal analyzer features an LED bar graph, and the generator has three tone frequencies and three levels.
