The DAM-2000/2200 series is ideal for applications where up to 40 high quality audio channels need to be sent over fiber
such as concerts, live productions, recording studios, church production, staging, theatrical productions, studio to
transmitter (STL), studio to studio, common carrier, RBOC Telco circuits, distance learning and back-haul feeds from
special events.
Featuring full 20Hz to 20KHz audio bandwidth, S/N of 90dB and a THD of 0.05% the DAM series meets the rigorous
broadcast industry standards.
The XLR interface panel permits quick and easy connections and serves as a patch panel. Monitor and control functions
include audio and optical front panel status indicators with dry alarm relay contacts.
The DAM-4000 is a compact unit designed for stand alone, wall mount or rack-mount applications. Advanced CWDM
technology is available which enables up to 16 units to be put on one strand of fiber.
