    The wireless speaker transmitter is designed to work with a wide variety of devices. Our tests have shown the default volume levels of iPods, iPhones, MP3 players and other devices connected to the transmitter through the headphone jack do not have the signal strength required by the transmitter. Raising the volume of your device will increase the signal strength to the transmitter. The signal LED will show a steady light when the required signal strength from your device is reached. We recommend that you keep the volume set on your iPod, iPhone, or other audio source at a minimum of 3/4 of full volume.

    Many modern TVs, home theater, and stereo receivers do not have a simple output jack for headphones. Instead they have a limited volume audio output set of RCA style jacks. The sound coming out of them is set to a low volume that cannot be increased using your remote's volume controls. If the audio source device (TV, receiver, computer, etc.) is connected to the wireless speaker transmitter through the audio out port and there is no audio signal from the transmitter to the speaker(s), an inline headphone amplifier will increase the signal strength from the source to the transmitter. Cables Unlimited recommends the Boostaroo amplifier at Please click here to review.

    Please note:
    Low or distorted sound on speakers or with a transmitter powered by batteries can be caused by batteries that are discharged or have low capacity. Test by removing batteries and connecting the AC power adapter, or using a fresh set of batteries.
