L/R symmetric circuit layout
improves channel separation. Stabilizes the amplifier and it’s internal
componentry by absorbing outer
vibration with superior speed.

H-Shaped Chassis TVC (Total Vibration Control) Technology
For superior sound quality across a wide
spectrum, Pioneer’s TVC (Total Vibration
Control) technology thoroughly suppresses
vibration from parts and mechanisms that
can interfere with sound.

Class-D amplifiers overcome the inefficiencies of traditional
Class-A or AB amplifiers. Pioneer’s Class-D amps transform
very little power into heat while a very high percentage
of the power supply (67 %) is transformed into the load.
This results in a very compact amp which needs little
input power to produce very high output power.
The Class-D amplifier’s PWM (Pulse Width Modulator)
modulates the original audio input signal with another
signal which has a much higher fixed frequency. The result
is a digital signal which contains the input signal and a
band of frequency components around the modulation
frequency. A LPF (Low Pass Filter) will then filter out the
high frequency pulses and the resulting amplified output
signal is then sent to the subwoofer and/or speakers.

With the PRS-D2000SPL, PRS-D1200SPL and PRS-D1200M’s SYNC connection, adjustment
of the master amplifier also adjusts all other amplifiers in the cascade. This makes control
simpler and more convenient.
* These are only a few examples of connection configurations for the PRS-D2000SPL. Ask your nearest car
stereo installer or dealer about power/ground wiring and installation details for the PRS-D2000SPL,
PRS-D1200SPL and PRS-D1200M.
*1 Ω minimum speaker impedance for this configuration or damage will occur.
**2 Ω minimum speaker impedance for this configuration or damage will occur.
Caution: Having more than four amps in a sync configuration is not recommended.
Sine waves can put excessive stress on an audio system, so if a sine wave source is used at high
output level, damage can occur.
Caution: To avoid damaging your amplifier/subwoofer system, please make sure that the continuous power output of the amplifier is lower than the nominal power handling of the subwoofer.
