Pioneer PRS Series: The Pioneer PRS series amplifiers
cleanly amplify the music signal, free of distortion or added color.
Class D Amplifier: The PRS-D1200SPL is a Class D mono amplifier, delivering huge power with low heat and distortion.
1-Ohm Stable: The amp
can be connected to loads with impedances as low as 1 Ohm. The lower the impedance, the higher the power output:
- 500 watts x 1 at 4 ohms
- 1000 watts x 1 at 2 ohms
- 1200 watts x 1 at 1 ohms.
Externally Bridgeable: This mono amplifier can be externally bridged--joining two amplifiers together as one--doubling the power to a single woofer or voice coil.
Multi-Amplifier Synchronization System (MASS): Pioneer's proprietary Multi-Amplifier Synchronization System technology allows one amplifier (master) to control the settings of other amplifiers
when two or more amps are "strapped" together. This eliminates the need to adjust each amplifier gain separately.
Dynamic Amplifier Protection (DAP): Dynamic Amplifier Protection is a
specialized circuitry which protects the amplifier from failing by automatically reconfiguring itself based on output signal level. Two top-mounted indicators will light when the amplifier's
temperature rises beyond a certain level, or if some other type of problem has occurred in the amplifier.
Controls: The amplifier is equipped with the following controls and switches:
- Mode Select: a 3-way switch to set the amplifier's sync mode (Master, Sync, Sync Inv). A "stopper" must be removed before switching from "Master" setting.
- Gain: a rotary control (6.5V to 0.4V) to set the input sensitivity of the amp
- Low Pass Filter:The PRS-D1200SPL has a 40-240 Hz, continuously variable low pass filter to optimize your system's efficiency and delivers the best possible sound quality. This low pass filter has a slope of
- Subsonic: The amp has a 20Hz subsonic filter to remove power-robbing frequencies below the tuning of your subwoofer or enclosure. The subsonic filter has a slope of
- Bass Boost: The amplifier features a selectable bass boost control with a wired bass remote. The bass boost frequency is variable between 20 Hz and 120 Hz, adjustable on the amplifier. Once you
set the frequency, you can select amount of bass boost right from the driver's seat using the wired bass remote. The level is selectable at 0dB (flat), 6dB, 12dB, or 18dB.
- BFC Switch: Beat Frequency Control switch--if you hear a beat while listening to an AM radio broadcast, change the position of the switch with a small flat screwdriver. (This unmarked
switch is located beside the power terminals).
Hidden Connections: For a clean installation, the amp's connections are located on the ends of the amplifier under removable terminal covers. The connections include:
- Left Side of Amp:
- Fuses: four 40A ATO fuses
- Power: set screw terminal capable of accepting up to 4 gauge wire
- System Control: set screw terminal capable of accepting up to 10 gauge wire
- Ground: set screw terminal capable of accepting up to 4 gauge wire
- Right Side of Amp:
- Sync Input/Output: stereo RCA jacks for use when "strapping" two or more amps together
- Input: stereo RCA jacks for line-level input signal
Bass Boost: RJ14 jack for use with the supplied wired Bass Boost remote
- Speaker Output: set screw terminals capable of accepting up to 4 gauge wire
Wiring Recommendation: It is recommended that the amplifier should be protected with a 200-amp fuse at the battery. The 4-gauge amplifier wiring kits sold by Crutchfield all have a
100-amp fuse included, with either an AFS or Maxi-style fuse holder. If a 200-amp Maxi or AFS fuse cannot be found, an ANL-style fuse holder (211FHXL4) and 200-amp ANL fuse (211FANL200) should be
