 Lightweight Powerhouse Pro Amplifier

The Rockville RPA4 1000-watt power amplifier combines efficiency with great sound to deliver a lightweight amplifier that packs a ton of punch. This amplifier is engineered using advanced design and components creating a lightweight design and extremely reliable operation that can pound on a daily basis for years and years of use. The computerized IC controlled protection circuitry allows delivery of peak power while preventing overloads. The RPA4 is optimized for 4 and 8-ohm speakers, and is equipped with a stereo/mono speaker output switch allowing for quick system impedance optimization. The RPA4 amp fits perfectly into standard 19” racks, and is lightweight enough (less than 20 lbs.) to make it incredibly easy to transport. 

The Rockville RPA4 1000-Watt Power Amplifier at a Glance:

• Perfect amount of  power for your application
• Efficient operation
• IC controlled  protection from overloads
• Subwoofer-ready when  you are

Efficient operation
Manufactured using a premium oversize toroid power transformer for reliable performance coupled with a fan cooled air movement system; this amp runs cool and efficiently so your music will never stop. The cooling system is designed to pull in cool air through the large vents in the amplifiers’ front panel. This cool air then travels through the amplifier, over the power transformer and the internal transistor aluminum heat sink and exhausts out the rear of the chassis. The continuous airflow keeps the transformer and output transistors cool so your system can keep playing for hours and hours at peak performance without any thermal issues. Our goal is to ensure stable performance and long life.

Computerized IC Protection Circuitry
Our unique IC monitoring protection circuit allows for full peak power delivery while preventing detrimental overloads. In case of extended clipping the circuit reduces gain slightly to keep the music playing cleanly while protecting the speakers from excessive distortion levels.

Mono Subwoofer-ready
A stereo/mono switch on the rear of the system allows for quick configuration to either  use multiple speakers in stereo mode or bridging the power and using one subwoofer in mono mode.
