AUDIOPHILE GRADE

The DEH-80PRS CD receiver features audiophile grade internal components and materials that are carefully selected to achieve Pioneer’s highest standards for the ultimate in sound quality. Pioneer’s exclusive sound field technologies including Auto EQ and Auto Time Alignment help optimize audio in ways that perfectly suit particular listening spaces and allow subtle manual control of settings. Versatile connectivity helps deliver exceptional sound quality from various digital devices.

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

Four-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. Our 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.

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.

• 3-Way Digital Network: The DEH-80PRS features a 3-Way Digital Network, connecting (via three 5V RCA preouts) up to three external amplifiers, each dedicated to driving high-, mid- and low-frequency ranges, respectively. The result: more distinct separation of the three frequency ranges, for more full, natural sound realizing more of each speaker’s potential in a multi-speaker system.
• L/R Independent 16-Band Digital Equalizer: The L/R Independent 16-Band Digital Equalizer 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.
• Auto Time Alignment and Auto EQ: Time alignment automatically estimates the delay from each speaker to the driver’s position and adjusts speaker sound output timing, so that sound from all speakers reaches the driver’s ears in perfect sync. Auto EQ tailors specific musical characteristics according to preference, uses a microphone to monitor and analyze acoustics, then automatically fine-tunes all frequency bandwidths and front and rear speaker digital parametric equalization. These processes occur in 399 seamless steps in just about 6 minutes and 30 seconds.
• Time Alignment: Not only can this function precisely adjust each speaker’s output timing according to its distance from the listening position – it is also adaptable to a 3-way multi-amplifier and speaker system.
