Introduction
Kaleido-X, Kaleido-X16, Kaleido-Modular-X, and Kaleido-MX multiviewers support
embedded audio in SDI signals, but there are cases when embedded audio is not available
(e.g. analog inputs, or not embedded) or extra audio inputs are required. The ABT provides
connector space for the audio signal inputs, and multiplexes all the audio signals into
combined serial feeds on coaxial cables that connect to the multiviewer.
Features include:
• Up to 128 channels of audio processing (depending on model)
• Analog or digital audio inputs
• Dual redundant SDTI outputs on standard video coaxial cable
• Internal tone generator
• 0 dBFS adjustments on analog inputs
• Locks to video, AES or Word clock reference (48 kHz only)
• Compatible with non-PCM signals
• Complies with IEEE 802.3af standard for Powered Over Ethernet devices
• Occupies 3 rack units, 4 cm (1.57 in) width (plus connectors)
• Can fit in the back of racks
• Can be located up to 250 m (800 ft) away from the multiviewer
Description
The ABT is designed to mount in a standard 19 in rack, and is 3 RU high. All connections are
from the rear.
