FPM-D accepts 2-channel PCM and converts it to stereo analog audio for the SonaFlex system via Cat5 and analog outputs for local systems. Ideal for sources such as AppleTV. FlexPort audio input transmitters serve as remote input modules for SonaFlex SF-16M matrix amplifiers. FlexPort transmitters are available in several different styles, including balanced line/mic, XLR, digital SPDIF and analog RCA audio signals. Audio signals are transmitted to an SF-16M via Cat 5e/6/7 cable up to 500 feet and made available to specified amplified outputs, and can be shared with up to three additional SF-16M amplifiers. Each transmitter has a convenient override button.
