Marine stereos are rated as spray resistant or waterproof. Why? Because unlike automotive stereo receivers, boat stereo receivers have features like coated circuit boards which enables them to resist corrosion in the wet marine environment.
Dual receiver radio Bluetooth#
Pairing a Bluetooth phone to the XDMA6700 involves a straightforward process: using either the stereo or a button on the Bluetooth module, users set the system to discovery mode and then complete the process by searching for devices with their cell phone.If you are looking for a new marine stereo receiver head unit, we have some suggestions to make.įirst be sure to select a true marine stereo receiver. When connected to the Alpine's plug-and-play BTM60 wireless Bluetooth module (also sold separately), the XDMA6700 can be turned into a very useful hands-free calling interface. We found in our test of the acoustic output that the XDMA6700 delivered a weak, tinny bass note and there was little demonstrable difference between the preset EQ settings in terms of audio output. For audio tweaking, users can choose between five preconfigured EQ settings (pop, jazz, classic, beat, rock), and EQ levels can also be customized manually using the main control dial. All audio sources play out through the XDMA6700's simple 1-bit digital-to-analog converter with a power output of 17 x 4 channels. However, the system cannot be used as either a satellite- or HD-radio receiver. In addition to its AM/FM receiver and its disc playback, the XDMA6700 can be used to play iPod tracks using Dual's add-on iPlug cable, which is sold separately. The system's search function works with the right number of letters entered but is labor-intensive to program.
In general, we like the option of being able to search for tracks on vast digital audio libraries, but the process of entering the required information is too labor-intensive to make the XDMA6700's search function a really useful tool. The alphanumeric search function works adequately well but requires entry of at least three digits to return decent results-two-letter searches result in every listing with those two letters in some part of either the song title or artist name being returned: for example a search for "to" brought up "A Message to You" (a track name), and Face to Face, Fear Factory, and Pato Banton (all artists). The search function can be used to find specific tracks, although the system does not differentiate between artists or track titles when performing its search. Tracks can be searched either numerically or alphabetically after the rather arcane search initiation procedure (hold down the mode search button> press the same button again> turn the rotary dial to the required letter number> press the enter button to preview the results> press the same button to make a selection). The XDMA6700 has a unique search function that enables users to fast-forward through the tracks on a disc to find what they are looking for without having to repeatedly press the forward skip button. For navigating digital audio libraries, the XDMA6700 makes use of two search buttons as well as its 12 keypad buttons, which each have a phone and audio function. The XDMA6700's monochrome LCD display can show only eight characters at a time, but the brisk automatic-scrolling feature ensures that information can be viewed more quickly than on similar units, such as the JVC HD KDR1. Using the Disp button (the number 0 on the keypad), users can toggle between each of the categories, with a corresponding logo appearing on the top of the display. With compressed digital audio files (such as MP3) playing, the display can be set to show one of a selection of ID3 information tags, including info on track name, directory name, artist, album, and song title. The first impressions one gets when attempting to play these discs, however, are not very positive, as the system takes around 10 seconds from the time a disc is inserted to start producing any music.
The XDMA6700 can be used to play regular CDs as well as MP3- and WMA-encoded discs via its single disc slot. The XDMA6700's small phone keypad buttons double as a bank of audio controls, making it tough to control music on the fly.
