PRS — amplifiers
Pioneer’s PRS amps are designed to drive speakers to the limit — or rather, beyond the limit. Thanks to the MOSFET
power supply, these amps offer more distortion-free sound power than ever before. In addition, a 4-channel crossover
(PRS-X340) gives you several power options, while a high/low switch lets you choose between 3 – 9 kHz or 40 – 120 Hz.
The bandpass filter makes bi-amplifying a breeze. So, if you want truly awesome power, it's even possible to mount two
PRS series amps together.
❚ MOSFET Devices for Optimum Performance
Pioneer MOSFET output devices, incorporated in all Pioneer PRS series
amplifiers, offer significant advantages over traditional bipolar devices such as
faster switching results, less crossover distortion and less noise. High power
used to mean high heat and resistance that could lead to noise — but not
anymore. Pioneer PRS amplifiers use a PWM Regulated MOSFET power supply
unit that's designed to keep its cool even under pounding pressure.
With full MOSFET-driven power supplies and MOSFET output sections, Pioneer
PRS amplifiers are better than ever at delivering power!
❚ Intelligent Power System
A car’s normal 12 V ~ 14 V power supply restricts output power to a theoretical
limit of about 50 W through a 4 ohm load. For more power, all Pioneer PRS
amplifiers use a PWM Regulated MOSFET power supply unit to boost the car’s
line voltage and control their own power supply.
This control is exercised by Pioneer's Intelligent Power System, which does
everything to ensure you get peak power output without noise by giving an extra
current boost to the speakers to compensate for any drop in voltage caused by
other electric loads in the car. You can now have the power you crave.
❚ Mount PRS Series Amps Together
Mount two PRS series amplifiers together to create one massive amplifier. The
mounting feet on the interior side can be removed or rotated inward to allow the
amplifiers to mount flush against each other.
