Overview

The 1300B-M series links incorporate two preamplifier channels for
microphone level audio providing up to +70 dB front end gain. The
units can supply microphone phantom power at +48 VDC or a
single-ended supply of +12 VDC on an individual channel basis. This
makes the 1300B-M unit capable of interfacing directly to virtually any
microphone.

Superior Performance

Superior noise performance and wide dynamic range makes the
1300B-M an effective solution for the transmission of microphone
audio via fiber when used in conjunction with the B722A 2-channel
audio transmission system.

Built-In Diagnostics

The 1300B-M incorporates built-in diagnostic capabilities that include
LEDs that monitor preamplifier operation.
