Overview
The 1300B-M series links incorporate two preamplifier
channels for microphone level audio, providing +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.
