Headunit
Marine Certified: Rockford Fosgate's PMX series of source units are fully tested against UV radiation degradation as well as tested to IPX water intrusion standards. They are also fully tested for ever changing environmental conditions such as temperature extremes, as well as vibration testing to make sure they can take a bump and keep performing. The PMX-1 is protected against Dust, UV, Temperature, Water, Corrosion & Vibration.
- Dust: The unit's display and motor structure are sealed up tight so they look as clear as possible and perform day in and day out no matter how many times you hit the trails.
- UV Inhibitor Materials: Centrex and ASA plastic materials are used for UV radiation resistance and components are tested in accordance with ASTM D4329 testing and certification procedures.
- Thermal Shock Tested: Tested for extreme temperature operation as well as severe fluctuations in ambient temperature. Components are taken to both low and high temperature extremes and then tested to ensure operational capabilities.
- Water Tested: IPX6 Rating allows for the components to be directly sprayed with water without water incursion.
- Corrosion Protection: Two part epoxy coated PCB boards prevent corrosion of critical components due to exposure in moisture rich environments.
- Vibration: Subjected to full vibration and shock testing to ensure that it will take abuse and keep performing to our stringent standards.
Applications: The PMX-1 digital media receiver is designed for marine and motorsports systems.
Optically Bonded LCD: The Rockford Fosgate PMX-1 features a 2.3" LCD screen (with white background and black text) for optimum viewing, even in full sun. The LCD screen is optically bonded to prevent any dust or moisture penetration. There are two brightness settings for the LCD screen.
Water Resistant Control Knob: The PMX-1 uses a water resistant rotary encoder knob, along with push-button controls that feature white LED illumination.
Voltage Gauge & Warning: You can check the voltage of your system through the PMX-1's menu. The unit also provides a Low Voltage Warning Alert.
EEPROM (Electrically Erasable Programmable Read-Only Memory): The Rockford Fosgate PMX-1 features an EEPROM memory system which retains settings (including Audio & Bluetooth settings) even when power is removed.
Bluetooth Music Streaming: The Rockford Fosgate PMX-1 offers built-in Bluetooth (version 3.0+EDR) for wireless music playback from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows phone, Blackberry, and more. You are able to stream stored music and music apps from your Bluetooth device to the PMX-1 marine receiver. You can control basic playback functions like Play/Pause, Previous Next/Track and Repeat/Shuffle for stored music and music apps on your device. When using a Bluetooth AVRCP 1.4 compatible device like the Apple iPhone (iOS 5.0+) or an Android smartphone (OS 4.0+), you can even browse your stored music by category (Playlist/Artist/Song/Genre). The PMX-1 will also display your device's song/artist information with album art.
AM/FM Tuner: The PMX-1 features a built-in AM/FM tuner with manual, seek, and preset tuning. You can store up to 18 FM and 12 AM preset stations; these presets can be stored manually or automatically. You can set the tuner to Local or Distance tuning. The Local option tunes to nearby radio stations with sufficiently strong signals for good reception. In areas where reception is poor, switching to Distance tuning enables the unit to tune in to more distant stations. You can choose between US or European tuning.
Weather Band: The Rockford Fosgate PMX-1 is also equipped with a built-in weather band tuner. Select from weather band frequencies between 162.40 to 162.55.
MOSFET Amplifier: The PMX-1 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.
- Full Bandwidth Power: 25 watts RMS x 2 channels (at 4 ohms, 20-20kHz, 1% THD)
- Maximum Output Power: 50 watts x 2 channels (100 watts total)
Equalizer: The PMX-1 is equipped with a variety of EQ presets, and 7-Band EQ, and Rockford Fosgate's Punch EQ.
- Presets: Select between seven EQ presets - FLAT, ROCK, CLASSIC, ACOUSTIC, DANCE, ELECTRONIC, or HIP-HOP.
- 7-Band EQ: Use the built-in 7-band EQ to custom tailor the sound of your music to your liking.
- Punch EQ: Punch EQ is an onboard equalizer with up to +18dB at 45Hz and/or up to +12dB boost at 12.5kHz.
High-Pass Crossovers: The PMX-1 provides a high-pass crossover for the two output channels which can be set to 60Hz, 80Hz, 120Hz, or Full-Range.
Source Gain: You can adjust the gain of each source so they all play at the same volume level. Select between -3dB, -2dB, -1dB, 0dB, +1dB, +2dB, or +3dB for each source.
Key Beep: A beep tone will sound with any press of a button on the receiver. This can be turned on or off.
Face Dimensions: The receiver face has the following dimensions:
- Nose:
- Width: 4.335"
- Height: 3.955"
- Trim Ring:
- Width: 4.495"
- Height: 4.125"
Optional Wireless Remote Control: The PMX-1 headunit is compatible with the Rockford Fosgate PMX-BTUR universal Bluetooth remote control (sold separately). The PMX-BTUR is designed to be used with any audio system that utilized a smartphone or tablet as a music source through Bluetooth connectivity. The wireless Bluetooth remote control includes two mounting options, a hand-held bezel and a steering wheel bezel with a hook-and-loop strap to easily secure the remote to a steering wheel. With Bluetooth 4.0 connectivity, the PMX-BTUR quickly and easily pairs with your mobile device using simple one-button pairing and has a wireless range of up to 32.8'. The remote control lets you adjust Volume Up/Down, Play/Pause, and Previous/Next Track selection on your compatible Apple iOS 8.0+ or Android OS 5.0+ mobile device.
Speakers
Speaker Overview: The Rockford Fosgate Ranger Stage-1 audio system includes two pre-mounted, "Element Ready" 5-1/4" 2-way speakers.
