Simplified controls and larger screen (1.47 x 1.34 x 1.10? ? 81% larger) make it easier to use and easier to read. The blue back-lit screen makes the selected FM frequency more visible in low-light conditions. The mute button once housed on the volume control and is now on the face of the 3.0.

Mechanical Power On/Off Switch

Mechanical power switch stays on even when you suffer a power outage. The transmitter will turn on and return to the set frequency when power comes back on. Plus, it won?t drain the batteries like an electrical switch when powered off.

Stereo/Mono Selection

Choose between which mode you want to broadcast your audio. Listen to your music and other audio in true stereo format with the right and left channels. While mono broadcasts the audio signal further when needed.

Separate Line In and Microphone Volume Control

The line in volume and the microphone have separate volume controls. Turn up the volume on the mic while reducing the volume of the audio with a press of a button. Great for fitness instructors and karaoke.

3 Pre-set Frequency Buttons

Just tune the FM Transmitter to a frequency, hold the button in for three seconds and the WHT 3.0 instantly stores your favorite frequencies. Perfect for in-car use!

Redesigned Mute Button

We placed the mute button on the face of the 3.0 for easier use. The previous versions caused some confusion and this innovation was a direct result of valued customer feedback.

Full FM Frequency Range

The WHT 3.0 utilizes the entire FM frequency. It doesn?t matter if you are in a Brooklyn apartment or tucked behind a mountain in Washington. You are sure to find a frequency to broadcast your favorite audio source. 

Transmits Using PLL Technology

To give you the best transmission signal possible we insisted that our FM Transmitter use PLL (or Phase Lock Loop) technology so you won?t have to worry about the transmission drifting like on AM transmitters? or for that matter some other FM Transmitters out there on the market. 

US/EU Pre-emphasis

FM radio is a noisy medium. The noise has triangular distribution, meaning the noise is louder at higher frequencies. Without pre-emphasis, the high frequencies get buried in noise.

Pre-emphasis lifts high frequencies above the noise floor levels, enabling you to hear a clearer transmission signal.

That?s why we now offer you the ability to match the pre-emphasis with your region?s FM Radios.

Engineered to work any audio source, the NEW Whole House FM Transmitter 3.0 has limitless uses and broadcasts a clean and clear FM signal 150 feet in any direction.

Use it hundreds of ways and enjoy hours of your favorite audio sources.
