Burr-Brown 24-bit D/A Converters: Three Burr-Brown digital to analog converters are used - one each for the high, mid, and low frequency ranges; providing exceptional linear sound reproduction with wide dynamic range and faithful reproduction of the original source.

4-Layer Circuit Board Design: Utilizing a four layer copper foil board with components mounted to both sides of the board allows for a circuit board with a much smaller footprint. The inside layers of the circuit board are dedicated to the power and ground supply traces, which allow for lower overall circuit impedance and greatly reduce noise.

Full-Custom High-Capacitance Power Supply Capacitor: Custom-built capacitors in the power supply keep sound clear and consistent. Exclusive parts are developed and tuned for optimal sound quality through a thorough review of materials and repeated listening trials.

Sound Master Clock Circuitry: Timing is everything. Pioneer's new Sound Master Clock generates waveforms that read and process digital signals with extraordinary precision; eliminating jitter. Finely detailed signals can be accurately reproduced as they were intended.

MOSFET Amplifier: The DEH-80PRS 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.

CEA2006 Compliant: The power specifications for the DEH-80PRS are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the DEH-80PRS are as follows:

• CEA2006 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)

Three 5-Volt Preamp Output: The Pioneer Premier DEH-80PRS features three 5-Volt preamp outputs (Front, Rear, and Sub). The Front and Rear preamp outputs feature fade control, while the subwoofer preamp output is non-fading. If you are using external amplifiers to power your car audio system, you can choose to turn off the head unit's amp for better sound quality.

28-Bit Binary Floating-Point DSP: Handling a wider range of complicated calculations than a standard fixed-point DSP, Pioneer's 28-bit binary floating-point DSP along with the use of advanced programming technology allows for highly precise sound processing and tuning without degrading the source's digital signal.

Audio Operation Modes: This unit features two operation modes: the 3-way network mode (NW), and the standard mode (STD).

• 3-Way Network Mode (NW): This mode lets you create a 3-way multi-amp, multi-speaker system with separate speakers for reproduction of high, middle and low frequencies (bands), each driven by a dedicated power amp using the head unit's three 5-volt preamp outputs. The 3-way network mode provides network and time alignment functions; two functions essential for a multi-amp, multi-speaker system to enable precise control over settings for each frequency range. The 3-way network mode also enables low-pass, high-pass, level, and phase adjustments.
  • Time Alignment: The time alignment function lets you adjust the distance between each speaker and the listening position from 0 to 160-inches.
  • High-Pass Crossover Filter: The HPF cuts frequencies below the set frequency (1.25, 1.6, 2.0, 2.5, 3.15, 4.0, 5.0, 6.3, 8.0, 10.0, or 12.5 kHz), letting high frequencies through to the connected speakers.
  • Low-Pass Crossover Filter: The LPF cuts frequencies above the set frequency (25, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz), letting low frequencies through to the connected subwoofers.
  • Mid-Pass Crossover Filter: This allows you to set a HPF frequency (1.25, 1.6, 2.0, 2.5, 3.15, 4.0, 5.0, 6.3, 8.0, 10.0, or 12.5 kHz) and LPF frequency (25, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz) to allow only a specific range of frequencies to played through the connected speakers.
  • Slope: You can adjust the HPF/LPF/MPF slope for each speaker unit connected - LPF Slope (-36, -30, -24, -18, or -12 dB/oct), MPF (-24, -18, -12, -6, or 0 dB/oct), and HFP (-24, -18, -12, or -6 dB/oct).
  • Level: You can adjust the level of each speaker unit connected - High Frequencies (-24 to 0 dB), Mid Frequencies (-24 to 0 dB), and Low Frequencies (-24 to +6 dB).
  • Phase: You can switch Phase (Normal or Reverse) for each speaker unit's input signal.
  • Mute: You can mute each speaker unit (filter. When a speaker unit (filter) is muted, no sound is output from that speaker.
• Standard Mode (STD): This mode lets you create a 4-speaker system with front and rear speakers using the head units speaker outputs, or a 6-speaker system with front and rear speaker and subwoofers using the head units preamp outputs.
  • Subwoofer Output: This unit is equipped with a dedicated subwoofer preamp output which can be turned on or off. You can adjust the Phase (Normal/Reverse), LPF (50/63/80/100/125/160/200Hz), Slope (-18/-12/-6dB), and Level (-24 to +6 dB) of the unit's subwoofer preamp output.
  • High Pass Filter: The head unit features an independent High Pass Crossover Filter for the Front and Rear speakers. You can set the High Pass Filter for the front and rear speakers from 50, 63, 80, 100, 125, 160, or 200 Hz. You can also adjust the slope of the HPF to -12, -6 or 0 dB/oct.
  • Speaker Level: You can independently adjust the output level of the front and rear speakers from -24 to 0 dB.
  • Mute: You can mute front and rear speaker units separately. When speakers units are muted, no sound is output from those speakers.

Position Control: 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 by selecting the distance for each individual speaker in the vehicle compared to your listening position.

Auto TA (Time Alignment) w/ Auto EQ (Equalization): The Pioneer Premier DEH-80PRS comes with a wired set-up microphone for automatic time alignment and equalization to make setting up your vehicle's car stereo system simple. The supplied microphone plugs into the front-panel 3.5mm port on the face-plate and should be placed in the center of the driver's seat headrest facing forward (stop the car in a place that is as quiet as possible, close all doors, windows, and the sun roof, and turn the engine off). The auto-time alignment is automatically adjusted for the distance between each speaker and the listening position. The auto-equalizer automatically measures the car's interior acoustic characteristics, and then creates the auto-equalizer curve based on that information.

Equalizer: The Equalizer lets you adjust the equalization to match your car's interior acoustics characteristics as desired. There are 5 Preset EQ curves & 2 Custom EQ curves (via a 16-band digital EQ) to choose from.

• Preset EQ: You can select from the following Preset EQ settings - Powerful, Natural, Vocal, Flat, Super Bass, Custom 1, or Custom 2.
• L/R Independent 16-Band Digital EQ: The L/R Independent 16-Band Digital Equalizer (20Hz, 31.5hz, 50Hz, 80Hz, 125Hz, 200Hz, 315hz, 500Hz, 800Hz, 1.25kHz, 2kHz, 3.15kHz, 5kHz, 8kHz, 12.5kHz, and 20kHz) is excellent at overcoming in-vehicle frequency response peaks and troughs. With fine tuning adjustments at 2/3 octave steps, tailoring the frequency curves to generate a flat response is possible in any type of car.

Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. Hear the detail, warmth, and clarity, the way the artist intended it, from all of your highly compressed MP3/WMA/AAC files stored on your USB/SD memory device, iPod/iPhone, and portable media players. By restoring data (especially higher frequencies) that tends to get lost in the digital compression process, Pioneer's Advanced Sound Retriever technology enhances audio reproduction nearly all the way up to 20 kHz frequencies

Loudness: The Loudness feature compensates for deficiencies in the low and high sound ranges at low volume.

Digital Attenuator: When listening to a CD or other source on which the recording level is high, setting the equalizer curve level to high may result in distortion. You can switch the digital attenuator to low to reduce this distortion.

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 volume level of the FM tuner, which remains unchanged. Each source can be independently adjusted from -4dB to +4dB.
