Powering the Transmitter Use the included micro-USB cable (RFA1-PC) to power to the transmitter. Audio is not input on this port. In some cases, the USB port on the back of your TV or audio device can provide power. If you have "buzzing or hissing" on an audio channel, use the included wall adapter (RFA1-PS). Connecting Signal Choosing the input signal is critical to getting the most enjoyable experience. First, identify what outputs are available on your TV.
❷ Optical Input Digital optical input is the most common and most straightforward method for setting up your system. Plug your device into this port using the provided optical cable (61036). Remove plastic covers from the end of the optical cable before inserting them into the TV and transmitter. This type of connection snaps in place when securely inserted. ❸ Coaxial Input Use cable (RFA-COAX) sold separately. This single RCA coaxial cable is often colorcoded orange or black.
a 2nd optical cable (610-36) into the optical output. Remove plastic covers from the end of the optical cable before inserting them into the soundbar or transmitter. This type of connection snaps in place when securely inserted. The Optical Output port is only an optical passthrough. This output does not have sound processing or decoding on this audio stream. DSP (Digital Signal Processing) The digital signal processing in SonicCast RFA1 is designed to improve your audio experience and simplify setup.

Narrow Voiceify AI also enables Voice Priority Surround Sound and Calm Commercial Technology. Wide Voiceify AI Wide Voiceify AI applies AI algorithms to voices in the 0.5kHz to 8kHz range. Wide Voiceify AI also enables Voice Priority SS and Calm Commercial Technology. Full Voiceify AI Full Voiceify AI applies AI algorithms to voices in the entire audio range.
Selecting DSP Modes The mode button ❼ allows you to set DSP and adjust the delay. The Mode LED indicates these settings on the top of the transmitter ❽. A short press of the mode button cycles through the DSP modes.
Network & Audio Status The Status LED ❾ indicates the status of both the audio input and if a receiver is connected. Audio Input Status Not Connected Connected Connected Device Connected No status until Audio Connected No Receiver Connected Receiver Paired Status LED Fade Red Fade Yellow Solid Green Pairing RFA1 broadcasts a pairing beacon when you can add additional receivers. To pair another receiver, please see the specific receiver guide.
Placement and Mounting Careful consideration should be used when choosing placement for the RFA1. While the RFA1 should work behind the TV, some TVs contain large metal plates that interfere with radio waves. Locate the transmitter away from WIFI base stations. Plasma TVs generate large amounts of RF that may interfere with RF signals. The transmitter can be wall-mounted with screw holes on the transmitter's bottom or with the hook and loop. Another option for mounting is a transmitter shelf.
