Description
The DC Audio PS1200x4 is a compact 4-channel full-bridge amplifier that delivers up to 1,200 watts for serious multi-woofer or front-stage builds, without occupying a large footprint.
- 4 Ohm per-channel power: 190W x 4 @ 14.4V. In practice, this means four channels can each run a speaker at a robust, clean level from a 4Ω load.
- 2 Ohm per-channel power: 300W x 4 @ 14.4V. Lower impedance on each channel increases available power, ideal for higher-sensitivity drivers or demanding front-stage components.
- 4Ω RMS bridged power: 600W x 2. Bridging two channels at 4Ω provides a strong dual-sub or subwoofer pairing option while keeping a compact chassis.
- 4 AWG inputs: Heavy-gauge wiring for power input supports stable, low-resistance delivery to the amp in spirited installs.
- Variable low pass filter and Variable high pass filter: Flexible crossover control lets you tailor the frequency range sent to each speaker, reducing distortion and improving staging in a multi-speaker system.
- Full Range Output 9–16.5V Capable: Designed to operate across a typical car electrical system, giving you headroom from modest to high-voltage setups.
- 12dB/Octave Crossover (YES)
- High/Low Pass: 50Hz–500Hz to suit woofer, midrange, and component-tower designs.
- RCA Jacks: Tiffany-style RCA jacks for clear signal paths.
- Frequency Response: 10Hz–20kHz for full-range audio reproduction.
- Other controls and indicators: Subsonic Filter NO, Bass Boost @45Hz NO, Phase Shift NO, Remote Control NO, Clip Indicator No, LED Power/Protect Lights.
- Signal-to-Noise Ratio: 90 dB, contributing to cleaner quiet passages with less hiss.
- Damping Factor: 90<, indicating control over speaker motion within the supplied load range.
- THD @ 4Ω: Less than 1%, reflecting low distortion at rated load.
- Fuse Rating: External 100A fuse requirement.
- Dimensions (Heatsink): 7.76" L × 5.23" W × 2.3" H (197mm × 133mm × 60mm).
- LED Status Lights: Power/Protect indicators for quick fault or standby checks.
- Master/Slave: NO
Benefits: The PS1200x4 suits compact 4-channel installs where space is at a premium but real power matters. Use it to power a four-speaker front stage, or bridge two channels to drive a sub with up to 600W per pair at 4Ω. The targeted crossovers help you shape the signal path precisely, while Tiffany-style RCAs and a robust 100A fuse requirement emphasize signal integrity and protection. With a wide 9–16.5V operating window and solid thermal management via a generous heatsink, it’s designed for enduring performance in demanding car audio builds.
