Features

Marine Ready: The Sony CDX-M50IP Marine AM/FM CD receiver features a conformal coated circuit board and a plastic cover over the top of the chassis to protect against humidity. The front panel and trim ring also contain a UV-resistant paint (tested under ASTM G154).

Drive S: The CDX-M50IP features the Drive S chassis platform. Drive S includes the CD mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism includes a suspension to resist shocks, a motor that draws less power, and a fast low-current pickup that improves durability and CD playback accuracy. The 52W Peak x 4-channel S-MOSFET Power IC produces clearer, more accurate sound, less distortion, and a higher signal-to-noise ratio than previous designs.

Amplifier Section: The head unit's amplifier is CEA-2006 compliant and rated at 17 watts RMS x 4 channels at 4 Ohms and 1% THD. The unit is also rated at 23.2 watts per channel minimum continuous average power into 4 ohms, 4 channels driven from 20 Hz to 20 kHz with no more than 5% THD. Peak power is rated at 52 watts per channel.

Disc Compatibility: The CD receiver will play CDs, CD-Rs, and CD-RW discs. The head unit also supports CD Text.

Compressed Audio File Capability: In addition to audio CDs, CD-Rs and CD-RWs, the receiver will play MP3, WMA, and AAC compressed audio files stored on a CD-R or CD-RW. Below are the following requirements and features for compressed audio file playback:

Note: The Album/Group number is displayed only when the album/group is changed.

Radio Tuning: The CDX-M50IP allows you to manual tune or seek tune AM/FM stations. In the Local Seek Mode, the unit will only tune in stations with very strong signals during Seek tuning. The Mono Mode allows you improve poor FM reception by selecting a monaural signal instead of a stereo signal. The radio features 5 memory bands to store and receive AM/FM stations. You can store up to 6 presets in each of the following bands - FM1, FM2, FM3, AM1 and AM2. Other tuner features include:

• Best Tuning Memory (BTM): This feature selects stations with the best signals within the selected band and stores them in order of their frequency. You can select from FM1, FM2, FM3, AM1, and AM2.
• Manual Tuning: You can manually tune and find your favorite radio stations one by one for FM1, FM2, FM3, AM1, and AM2.
• Auto Tuning: You can use the seek button to help you search quickly through the available stations and then choose your own presets from these available stations.
• Switchable Frequency Spacing: You can change the AM frequency interval from 10k to 9k, and the FM frequency interval from 200k to 50k by moving the switch on the bottom of the chassis.

Dynamic Soundstage Organizer2 (DSO2): Sony's Dynamic Soundstage Organizer2 uses proprietary circuitry to induce subtle phase shifts, simulating a sound source that is placed higher than the actual speakers in the vehicle. For example, when the DSO function is used in a vehicle equipped with speakers mounted low in the front doors, it creates virtual speakers in the dash to raise the soundstage. This unit offers three levels of DSO, each with a larger and higher soundstage. You can store the DSO setting for each source.

EQ3 Stage 2: You may select one of the following EQ presets: Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom or Off (flat). For the Custom mode, you can adjust the following bands:

• Low: +10 dB to -10 dB at 60 Hz
• Middle: +10 dB to -10 dB at 1 kHz
• High: +10 dB to -10 dB at 10 kHz

Loudness: This feature allows you to listen to your music clearly at low volume levels by reinforcing the bass and treble. The bass level is increased to +4 dB at 100 Hz while the treble level is increased to +2 dB a 10 kHz.

Preamp Outputs: The CDX-M50IP contains two pair of RCA preamp outputs - a front pair and another pair that can be set for the rear channels or for subwoofer operation. When set to subwoofer, the output becomes non-fading and a low pass filter is activated with a selectable cut-off frequency of 125Hz, 78Hz, or Off. You can adjust the subwoofer preamp output's volume level independently from the head unit's volume control from -10 to +10 in 1dB increments.

Front Panel Auxiliary Input: A front panel stereo 3.5mm minijack is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your marine audio system. The volume level of the auxiliary input is adjustable from -8 to +18 dB to compensate for any difference between the unit and your portable device. The aux input can be deactivated in the menu so it doesn't appear as an available source. The head unit comes supplied with a rubber cap that can be placed inside the minijack when it is not in use to keep it dry.

Optional Auxiliary Input: You can connect an additional auxiliary audio device (such as a portable digital memory player, cassette, MiniDisc, or VCR) when used with the optional XA-300 UniLink Auxiliary Input Adapter. The XA-300 uses the UniLink and Bus Audio inputs on the back of the receiver, and allows you to connect an optional CD/MD changer in addition to the auxiliary audio source.

Mounting Angle: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 45 degrees.

Auto Off: When installing in a vehicle without an accessory power wire at the radio location, you can set the unit to turn off automatically after a set amount of time. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

Dimmer: The CDX-M50IP feature a dimmer mode to dim the brightness of the display. You can choose from either "Dim On", Dim Off" or "Dim Auto". The Automatic Dimmer feature automatically dims the display when you turn your lights on. Note: The Orange/White illumination wire needs to be connected to the vehicle's headlight circuit in order for the automatic dimmer feature to operate properly.

Contrast: This feature adjusts the contrast level of the head unit's display in 7 steps.

Dual Illumination: You can switch the CD receiver's button illumination to Red or Blue. The player's display illumination remains white (background) and black (characters).

Auto Scroll: This feature allows long displayed items to scroll automatically across the display when the track is changed on a disc.

Eject: The CD disc can be ejected with the unit powered off. The CD player will automatically reinsert the disc if the disc is ejected and left on the lip opening of the player for 15 seconds or more.

Wireless Remote Control: The head unit comes supplied with an IR wireless remote control (RM-X151) for easy operation.

Wired Remote Compatibility: In addition to the supplied wireless remote, the receiver can be controlled by an optional wired marine rotary commander (item 158RMX55M or 158RMX11M). Both remotes are water resistant, so they are ideal for use on boats, where a head unit needs to be kept dry, but you need to control it from a damp remote location. The RM-X55M remote features a display which shows source and mode information, satellite radio information, and CD text information.

Steering Wheel Remote Ready: The CDX-M50IP is compatible with the PAC SWI-PS Steering Wheel control interface (item # 127SWIPS), which allows you to retain the use of your steering wheel and/or rear seat radio controls when replacing the factory radio in select vehicles. The interface plugs into the rear panel 3.5mm minijack provided for a wired remote control.

Note: Please consult the online Crutchfield Car Selector to confirm compatibility with your vehicle.
