Broadcast Devices ATB-300-1 Audio Toolbox w/ AES I/O

Product Description

The ATB-300 Audio Toolbox from BDI is a rack mounted solution to switching and routing in the digital or analog domain. All ATB-300’s feature remote control/status/alarm capability and programmable silence sensor with auto revert feature which allows the unit to revert back to the failed channel if audio is restored. AES I/O versions feature synchronous AES switching and frame rate conversion on every input. This DSP based product feature 24 bit technology throughout and can accept sample rates from 8-96 KHz. Output sample rates: 32, 44.1, & 48KHz user configured.

This basic configuration (ATB-300-1) accepts four AES3 inputs that can be switched and routed to four AES3 outputs.

Features

• Simple front panel menu programming of silence sense delay, priority channel, revert timeout - program up to 8 channels for secondary, tertiary, etc. sources , input mode selection, input/output gain and input phase inversion.
• Revert feature returns to primary channel when signal integrity is restored automatically
• Programmable silence threshold
• Proprietary "Silent Switch" feature for seamless switching between sources and synchronous AES switching creating no switching artifacts
• Frame Rate Conversion on all digital inputs
• Programmable Alarm Contacts - Momentary for remote start of alternate source, maintained for remote control status
• Fully Remote Control Ready - Parallel standard, serial interface optional
• Power Fail Memory - Returns to last channel selected upon power up
