Audio Interface with Fiber Optics

Audio Interface with Fiber Optics, RF Transmitters, Video Modulators

Line drivers, line driver/receivers and matching transformers are available for transmitting audio (one-way or bi-directional) over fiber optics, telephone wire or microwave links. These units provide required impedance matches plus provide power and drive the microphone and speaker.

AMT-600 Line Driver

AMT-600 Line Driver

AMT-600 Line Driver

Line Driver takes audio signals from Louroe Microphone (Models A, B, C, D, E, L-DT, or K) and amplifies it to 0 dB @ 600 Ohms balanced, for input over desired transmission (fiber optics, etc.). Provides one-way listen-only at the Louroe Base Station. 12 Vdc plug-in power supply included.




AMT/R-600 Line Driver/Receiver

AMT/R-600 Line Driver/Receiver

AMT/R-600 Line Driver/Receiver

A Line Driver and Receiver in one housing that provides two-way talk/listen between the Louroe Speaker/Microphone and Base Station. It contains two circuits. One is a Microphone Line Driver, the other a Line Receiver and Power Amplifier. Line Driver portion takes audio signals from the microphone and amplifies it to 0 dB @ 600 Ohms balanced, for input over fiber optics, or telephone line. Line Receiver portion receives audio at 0 dB @ 600 Ohms and amplifies it at a maximum of 4W output into an 8 Ohm speaker. A built-in 70V transformer provides constant voltage the Louroe Speaker/Microphone. 24 Vdc plug-in power supply included. NOTE: If one-way listen is required rather than two-way talk.




TR-2 Matching Transformer, 600 Ohm / 10K Ohm

TR-2 Matching Transformer, 600 Ohm / 10K Ohm

TR-2 Matching Transformer, 600 Ohm / 10K Ohm

A matching transformer, 600 Ohm to 10K Ohm. Used with AMT-600 Line Driver or AMT/R-600 Line Driver/Receiver in conjunction with transmitting audio over fiber optics or telephone wire. The TR-2 matches the 600 Ohm output of the transmission (fiber optics, etc.) and produces an output of 10K Ohms for input to the Louroe Base Station.
