Installation, Touchscreen, & Remote Features

Modular Installation Design: Pioneer's Modular Solutions receivers are designed for applications, often newer vehicles, with limited depth behind the dash that prohibits the installation of a traditional single-DIN (2") or double-DIN (4") receiver. This installation flexibility is achieved by physically separating the LCD touchscreen display from the sub-chassis that contains the CPU, control system, terrestrial radio tuner, amplifier and input/output connections. This allows the sub-chassis to be mounted in a different location or different horizontal/vertical orientation within the vehicle. To simplify installation and increase vehicle applications, Pioneer and Metra Electronics are partnering to develop Vehicle-Specific Radio Install Kits (coming soon - check for vehicle compatibility) that make the Pioneer Modular Solutions receivers both cosmetically integrated and simple to install.

• It is possible to install the DMH-C2550NEX with the LCD touchscreen attached to the chassis body or separate from the chassis body.
• Installations where the LCD touchscreen is not attached to the chassis body and is installed separately may require Pioneer's CD-RGB150E extension cable or RD-RGB150A extension kit (both sold separately - see Accessories Tab).
• The DMH-C2550NEX is compatible with standard double-DIN (4") installation dash kits. It is not compatible with standard single-DIN (2") installations dash kit.
• Do not block the cooling fan when installing the receiver's chassis either horizontally or vertically.

Clear Resistive LCD Touchscreen: The Pioneer DMH-C2550NEX features a 6.8" clear resistive LCD touchscreen display with a resolution of 800 (RGB) x 480, for a total of 1,152,000 pixels. The clear resistive panel is designed to enhance the visibility of on-screen graphics and images, making them appear clear and crisp. The touchscreen display allows you to control this unit and a connected component such as an iPod/iPhone, Android smartphone, Bluetooth phone, or USB mass storage class device. Menus appear on screen for making function choices, audio adjustments, and setting up the system.

• Favorites: You can register the desired menu items on the DMH-C2550NEX 's "Favorites" menu screen. Registering your favorite menu items allows you to quickly jump to the registered menu item by a simple touch on the favorites menu. Up to 6 menu items can be registered as a "Favorite".
• OSD + Backgrounds: The color of the on-screen display can be set to red, amber, green, blue or white. The background display can be selected from 8 different preset displays for the AV Operation screen and 5 different preset displays for the Home Menu screen. In addition, you can change the background display to other images imported from an external USB device.
• Widescreen Modes: You can choose from the following widescreen modes when playing back video - Full (4:3 picture is enlarged in the horizontal direction only; enabling you to enjoy a 4:3 picture without any omissions), Zoom (4:3 picture is enlarged in the same proportion both vertically and horizontally; ideal for a 16:9 screen), Normal (4:3 picture is displayed as it is).
• Picture Adjustments: You can store numerous video settings for the head unit's video sources and rear-view camera; including brightness (adjusts the black intensity), contrast (adjusts contrast), color (adjusts color saturation), hue, (adjusts color tone), temperature (adjust the color temperature), and Dimmer (adjusts brightness).

Parking Brake Interlock: This unit has a parking brake interlock system that prohibits viewing of video programming and operating certain controls when the vehicle is in motion. In order to watch video on the in-dash monitor, the vehicle must be stopped with the parking brake engaged. The head unit's light green wire must be connected to your vehicle's parking brake detection circuit. The head unit's touchscreen will display a "Caution" message, if you try to watch a video when your vehicle is in motion.

Note: The parking brake wire must also be connected and the parking brake engaged for certain setup functions and menu options.

Front-Panel Control w/ Custom Illumination: In addition to the touchscreen controls, the unit includes frequently used buttons along the left edge of the screen. The color of the button illumination can be set to red, amber, green, blue, white, or scan (constantly cycling through the color spectrum). You can also create a custom color to match your vehicle's interior lighting (112 colors to choose from).

Dimmer: The receiver's touchscreen display & button illumination can be dimmed manually, automatically or via a timer. You can set the unit's LCD touchscreen & button illumination to automatically dim when your vehicle's headlights are turned on (this function requires that the orange/white illumination wire in the wiring harness is connected to the vehicle's headlight circuit). You can also set a specific time and duration for unit's LCD & button illumination to dim.

Remote Functions: The Pioneer DMH-C2550NEX digital media receiver includes a wireless remote control and offers steering wheel control capability (adapter required).

• Reception Blending: If a digital broadcast reception condition gets poor, this unit automatically switches to the analog broadcast of the same frequency level. If this function is set to "On", the tuner switches between digital broadcast and analog broadcast automatically. If this function is 'Off', reception will be conducted within a digital broadcast.
• BSM (Best Stations Memory): The BSM (Best Stations Memory) function lets you automatically store the six strongest analog or HD stations under preset buttons 1-6 of the currently tuned band. The tuner has 3 FM banks and 1 AM bank. You can store 6 presets for each bank giving you a total of 18 FM presets and 6 AM presets.
• Local Tuning: Local seek tuning lets you tune in only those radio stations with sufficiently strong signals for good reception. There are four levels of sensitivity for FM and two levels for AM. The higher settings allow reception of only the strongest stations, while lower settings let you receive progressively weaker stations.

USB MSC Compatibility w/ High Resolution Playback: The unit's rear-panel USB (type-A) port and 58" USB extension cable allows you to connect a USB Mass Storage Class (MSC) device; such as a USB thumbdrive. The USB port enables playback & control of music, video, and photo files stored on your portable USB MSC device through the Pioneer DMH-C2550NEX. The head unit will also display your USB device's stored music information - including Elapsed playing time, Artist name, Song & Album title, as well as Album Art. The Pioneer NEX Series receiver even supports playback of high-resolution FLAC music files (up to 24-bit/192kHz). High-Resolution Audio is high-quality sound that exceeds CD standard. High-resolution audio captures and beautifully expresses all the details of your favorite music. USB devices that can be charged via USB will be charged when plugged into the digital media receiver 's USB port (5V/1.5A) and the vehicle's ignition switch is set to ACC or On. The Pioneer DMH-C2550NEX supports the following types of audio, video, and photo files recorded onto an inserted USB device.

Notes:

• The head unit's USB port does not support USB hubs or USB card-readers.
• Videos and Photos can only be viewed when the vehicle's parking brake is engaged.

Dual AV Inputs: The Pioneer DMH-C2550NEX has dual AV inputs to connect two external audio/video sources. The head unit has a rear-panel 3.5mm minijack AV input for connecting a portable audio/video device. There is also a rear-panel composite video/stereo RCA AV input for connecting a video component such as a mobile TV tuner or game console.

Video Output: A single RCA composite video-output jack allows you to an add external monitor, such as rear headrest or overhead monitor (sold separately). The video output can display a USB or AV-input video signal when its selected as the receiver's source, regardless if the vehicle's parking brake is engaged or not.

Note: CarPlay, Android Auto, & WebLink are not supported by the video output.

Camera Input w/ Parking Assist Guidelines: The Pioneer receiver is equipped with a composite video rear-view camera input for the addition of an optional backup camera (130NDBC8, sold separately). The unit provides on-screen guidelines to assist you when backing up and parking your vehicle. These guideline do not automatically appear on the rear-view image. You must tap the "Park Assist Guidelines" icon on the touchscreen while the rear-view image is visible on the receiver's touchscreen. You can also turn the unit's composite AV input into a second camera input for adding a front camera (sold separately). The dedicated rear-view camera input offers two view modes -

• Auto View: The unit features a function that automatically switches to the rear camera image. When the vehicle's transmission is put in reverse, the screen automatically switches to the rear view camera (violet/white wire of the harness must be connected to the vehicle's reverse lamp circuit for automatic video switching). Automatic video switching takes approximately 0.8 seconds.
• Camera View: There is also a Camera View mode which allows you to manually bring up the rearview camera image on the receiver's touchscreen monitor to check what is behind you while driving. You can leave the Camera View mode on if you want to see the rearview image at all times; for instance when towing a trailer.

Note: The rear view camera feature is meant as a back-up aid only; never solely rely on the rear-view camera when backing-up. In addition to using the rear-view camera, always look behind you to make sure everything is clear when backing up your vehicle.

Audio & DSP Section

24-Bit/192kHz DAC: The Pioneer DMH-C2550NEX is equipped with a 24-bit/192Hz digital-to-analog converter for superb quality audio playback from disc, USB, iPod/iPhone, Android, and Bluetooth.

MOSFET50 Internal Amplifier: The Pioneer DMH-C2550NEX is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

• CTA-2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
• Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
• Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)

Note: The power specifications for the DMH-C2550NEX are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.

4V/6CH Preamp Outputs + Sub Control: The Pioneer DMH-C2550NEX features three pair of 4.0-volt preamp outputs (Front/Rear/Subwoofer). The unit's front and rear preamp output can be faded (front/rear), while the subwoofer preamp output is non-fading. The Pioneer DMH-C2550NEX lets you adjust the subwoofer preamp output's phase (normal/reverse) and volume (+10 to -24).

Crossovers: The DMH-C2550NEX employs high-pass and low-pass crossovers to tailor the head unit to your connected speaker setup.

• Standard: Allows you to set the high-pass and low-pass crossover network for a standard Front, Rear, and Subwoofer speaker setup using either speaker-level or low-level outputs.
  • HPF: The head unit's -6 to -24dB/octave high pass filter only allows frequencies higher than those in the selected range (50, 63, 80, 100, 125, 160, 200Hz) to your front and rear speakers through the unit's speaker-level or line-level outputs.
  • LPF: The subwoofer preamp output features an -6 to -24dB/octave low pass filter so only frequencies lower than those in the selected range (50, 63, 80, 100, 125, 160, 200Hz) are output to your connected subwoofer.
• Network: Allows you to set the high-pass and low-pass crossover network for a complex 3-way speaker system with Highs, Mids, and Sub using low-level outputs only.
  • Highs: The high-pass crossover for your tweeters can be set to 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8, 10, or 12.5 kHz with a -6 to -36dB/octave roll-off.
  • Mids: You can set a high-pass and low-pass crossover from your midrange/midbass drivers. The low-pass crossover can be set to 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8, 10, or 12.5 kHz with a -6 to -36dB/octave roll-off. The high-pass crossover can be set to 26, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz with a -6 to -36dB/octave roll-off.
  • Lows: The low-pass crossover for your subwoofers can be set to 26, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz with a -6 to -36dB/octave roll-off.

EEQ (Easy EQ) + 13-Band Graphic EQ: There are seven stored equalizer curves which you can easily recall at any time. You can choose from - Powerful, Natural, Vocal, Super Bass, Flat, Custom 1, or Custom 2. The Custom 1 and Custom 2 EQ modes allow you to manually adjust the level (+/- 12dB) of each band of the head unit's 13-band graphic equalizer (50, 80, 125, 200, 315, 500, 800, 1.25k, 2k, 3.15k, 5k, 8k, and 12.5k Hz).

Auto EQ (Optional): The auto-equalizer automatically measures your car's interior acoustic characteristics, and then creates an auto-equalizer curve base on that information. The Pioneer CD-MC20 Auto-EQ microphone (130CDMC20, sold separately) is required to use this function. The Pioneer CD-MC20 Auto-EQ microphone plugs into your compatible Pioneer receiver's rear-panel AUX 3.5mm input. The Auto-EQ microphone should be placed in the center of your vehicle's driver seat headrest facing forward for EQ measurement.

Audio Settings: The head unit provides further sound adjustments for your car audio system.

• Listening Position & Time Alignment: For a better sound-stage you can select your optimal listening position. You can choose from All, Front Left, Front Right, or Front. You can also select to manually fine tune the sound stage, using Digital Time Alignment (DTA) by selecting the distance (0-200") for each individual speaker in the vehicle compared to your listening position.
• Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. When the Advanced Sound Retriever is on, the high frequency range is compensated to match the frequency response curve to the original sound. There are two available levels of the Advanced Sound Retriever effect.
• Bass Boost: You can easily boost the subwoofer bass level by using the Bass Boost function. The Bass Boost feature allows you increase the subwoofer level from 0 to +6 (12dB).
• Loudness: The Loudness function compensates for deficiencies in the low- and high-frequency ranges at low volume. You can set the Loudness to High, Mid, Low, or Off.
• Speaker Level: You can adjust each speaker and sub channel independently from +10 to -24 to best even out the sound in your vehicle.
• Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the unit's FM volume level, which remains unchanged. Each source can be independently adjusted from -4 dB to +4 dB.
• Auto Level Control (ALC): This function automatically corrects the audio level difference between the music files and/or the sources.

Rear Speaker Setup: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.

Beep Tone: The in-dash head unit provides an audible beep to confirm button operation. You can turn this feature on or off.
