Class D monoblock amplifier

Available Finishes:

Pure Performance.

The PA 1200.1 monoblock subwoofer has the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching.

PA1200.1 Features:

Monoblock amplifier for subwoofers like our MM and db models.

1200 Watts x 1 (1 ohm), 800 Watts x 1 (2 ohm) and 400 Watts x 1 (4 ohm) continuous power. CEA-2006 compliant specifications for true, accurate power ratings.

Externally bridgeable with a second PA1200.1- for even more power!

Bridged power is 2400 watts (2 ohm) continuous and 4800 Watts dynamic power!.

1 ohm stable design can drive even the most demanding subwoofers.

Super efficient class D pulse width modulation amplifier design draws less power and runs cooler, so you won’t heat up the inside of your vehicle or make the headlights dim.

High-speed MOSFET switching power supply and high current bipolar output transistors pump maximum voltage and high current to your speakers or subwoofers.

Double layer fiberglass epoxy printed circuit boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area.

6-way Smart System Protection (SSP) circuits: Power and ground-reversal protection, thermal and short protection, current overdraw and low impedance protection circuits with auto-standby mode ensure safety, reliability and durability.

Anodized extruded brushed-aluminum cover for maximum heat dissipation and great looks!

Cast aluminum textured end caps for optimized heat dissipation and hiding of connectors. Solid aluminum logo and model panel back lit in cobalt blue.

Adjustable 12 dB/octave low-pass crossover (30-250 Hz).

Switchable 8 dB bass boost at 40Hz for extra bass thump.

Variable input gain optimizes match with different signal sources (250mv to 7.5V).

Switchable 24 dB/octave subsonic filter protects ported subwoofers.

Switchable 180° phase inversion for easy sub to main integration or external bridge mono operation.

Mounting hardware with rubber isolation grommets and extra fuses included.

Light bar/fan output-Connect an optional LED light bar or cooling fan for custom installations.

Multi-color status LED gives instant information on amplifier operation.

Remote subwoofer level adjuster included.

Master/slave switch and RCA outputs for easy daisy chaining of other amplifiers. Master/slave switch allows parallel operation

Power and ground terminals accept bare wire up to 4 AWG.
