MULTIMEDIA DIGITAL RECEIVER
The GMR-LED is a Multimedia Digital Entertainment Controller with a 160 watt internal amplifier. The unit features AM/FM//Weather band, Bluetooth® and USB input options. The Digital Receiver was unveiled to anxious boat builders at the IBEX show in 2018. Now the RV industry, off road builders and marine enthusiasts are joining the installers choosing the GMR-LED for their installations.

RADIAL SHIFT UX
The GMR-LED features a RADIAL SHIFT UX control system. This is an intuitive control navigation with master control and radial menu selections. Simply scroll the control to the desired feature, hit select, adjust and you are done.

RADIAL SHIFT UX - ICONS
There are 8 choices in the UX menu, each is assigned a specific icon: AM, FM and Weather band each have an icon, plus the inputs of Bluetooth, Auxiliary, USB and Camera each have a selectable icon. Lastly, is the "settings" option which is detailed clearly in the manual.

USB CONTROL & INPUTS
Easily connect smartphones, portable media devices and streaming services. iPod control allows full Apple® connectivity.

The multimedia controller supports MP3, WMA, and WAV audio with a USB thumb drive connected. Additionally, M4A or Apple Lossless file types are supported.

DUAL AUDIO ZONE CAPABILITIES & EQUALIZATION
The GMR-LED includes an innovation equalization system. first, in the classic definition of an EQ, the engineers have included an 8 bands of EQ that you can customize with different settings. Beyond that, you have DUAL AUDIO ZONE operation. Think of the different areas of your vehicle. In an RV, it could be the Pilot seat vs the "way back" or the galley. In a boat, you can control the volume in two different areas independently, such as the captain/passenger area and tower speakers facing the skiers or wake surfers.

BASS FREQUENCIES
To fine tune the subwoofer frequencies you have two controls. One to adjust the crossover frequency, with an internal adjustment that you access with the RADIAL SHIFT UX. The frequencies are at 80Hz, 100Hz and 120Hz. Next you can adjust the SUB level within the RADIAL SHIFT UX.

DUAL AUDIO ZONE
Adjust the relative volume level for the front/rear preamp outputs which will be connected to component amplifiers, from 0 to 40 on the RADIAL SHIFT UX. Here are a couple designs from the owners manual so you can see how to be optimize the DUAL AUDIO ZONE feature.

INTEGRATED AMPLIFIER
The built-in amplifier will deliver 40 watts x 4 channels of power into your vehicle. That is 160 of total power. With quick heat dissipation the system can play loud and long for years of service.

MAXXIMUM CONNECTIVITY
With 4 volts output from the line outputs (RCA connectors) you can connect external amplifiers for speakers and subwoofers with six channels of connectivity.

Choose from several types of amplifiers in the MB Quart line of marine, off road and mobile amplifiers. From the compact NA2 line-up to the full marine options and of course, several choices of car audio amplifiers.

For speakers and subwoofers, you will decide if you need speakers hidden away into stock locations or more outdoor and off road options. Check out the full line of Nautic Speakers and Tower Speakers or more traditional car audio speakers. Of course the heart of music is hidden in the bass frequencies, that means subwoofers. MB Quart has that covered with waterproof Nautic and car audio subwoofers.

MEDIA SCREEN
On board 3.5 inch high-contrast LED screen to view media artwork and external camera input allows you to focus on controlling your vehicle and not straining to see what track you're on. When the Camera icon is selected in the RADIAL SHIFT UX, the screen becomes a color display for the camera input. Cameras are not included with this unit. See the manual for details.

• Designed for the Elements
  Their one-piece polymer basket is designed to stand the test of time, even after long exposure to the sun and salt. Rubber surrounds offer superior edge protection and are much more reliable than foam. And a grille-mounted tweeter allows the front of the woofer cone to be sealed, protecting the motor structure from sea spray
• Harman Standard Reliability Testing
  JBL speakers have to undergo a testing process that would destroy lesser speakers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time. In the case of our marine speakers, we add salt spray and UV to ensure that they provide years of enjoyment without missing a beat
• Individually Voiced
  For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That's not the case with JBL. We don't only listen to our speakers against the competition - we voice them against each other to ensure each line has the consistent JBL sound signature that's known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point

Specifications:

• Power Handling: 75W RMS, 225W peak
• Sensitivity (@ 2.83V): 92dB
• Frequency Response: 50Hz - 20kHz
