Audio Streaming

Audio streaming [A2DP] is an audio protocol of Bluetooth technology. This profile allows for audio to be streamed wirelessly from your compatible device, such as a Smartphone, to the source unit so you can enjoy your favorite music or streaming music service such as Pandora or Spotify, wirelessly.

Aux Input

The Aux Input allows you to connect to the audio output of an external device such as an MP3 Player or Smartphone so you can enjoy your music through your system.


Allows our Bluetooth equipped source units to make wireless hands-free calls when paired with a Bluetooth equipped Smartphone. Communicate via the built in microphone on most of our units [or external microphone if provided] and listen thru your car’s speakers.

Built-in Preset EQ

The built-in, Preset EQ allows you to chose from preset EQ curves for a variety of music styles such as Rock or POP.


ESP [Electronic skip protection] is a feature that buffers the CD while playing, storing 5 seconds of music. If disc reading is interrupted, the player momentarily uses the stored data, while the tracking circuitry finds the passage prior to the interruption on the CD for continuous performance.

Fully Marinized

Fully Marinized is the term we use for our Marine and Outdoor products that are Weather Proof. We integrate high-tech, state-of-the-art waterproofing materials plus special UV coatings for plastic surfaces, coated circuit boards and connections to protect the product against the harsh outdoor elements and resist corrosion.


ID3 Tag allows the audio file to store and display additional data such as title, artist, album, track number and more.

Pre-Amp Output

This units Pre-Amp outputs let you expand your system by adding up to 2 amps and/or signal processors.

SD Memory Card Port
