The AESIMP-12 series impedance converters allow transmission of AES/EBU digital

audio signals, with sampling rates ranging from 22kHz to 96kHz, over 75Ω coaxial

cables. The conversion transformer changes a balanced 110Ω transmission line to an

unbalanced 75Ω transmission line.

The AESIMP-12 series provides twelve XLR-3 type connectors (male or female) on

the balanced side and BNC type connector on the unbalanced side. Two versions of

the AESIMP-12 are available. The AESIMP-6F6M gives 6 converters in each direction.

The AESIMP-1M is a single channel converter.

The rack mounting ears may be reversed to orient the panel for the greatest ease of

installation. An identification strip holder is provided over the BNC connectors to assist

in labeling sources and/or destinations.
