Fiber Optic Microphone Preamplifier
Overview
Standard Features
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.
• Two-channel microphone input • 48 VDC phantom microphone power • 20 Hz to 20 kHz audio bandwidth per channel • -70 dBu to 0 dBu audio input range • Up to +12 dBu audio output • 100 dB audio SNR • 0.005% THD • Interfaces to standard fiber equipment
Superior Performance u
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.
