The AESIMP-16 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-16 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-16 are available. The AESIMP-8F8M gives eight 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.
