Power Dynamics PRS360 - 360W 100V Line Booster Amplifier

Power Dynamics PRS360 - 360W 100V Line Booster Amplifier

The Power Dynamics PRS360 is a power amplifier, also known as a booster or slave amplifier, specifically designed to expand and enhance 100V line-level sound systems. With a robust 360W of power, this unit is the ideal solution for adding more speakers or covering larger areas without replacing the main mixing unit. It has been optimized for seamless integration with Power Dynamics' PRM series of mixer amplifiers, though its versatility allows it to work with any system that provides a line-level signal.

Built on a robust metal chassis and ready for 19-inch rack mounting, the PRS360 is designed for the professional installer. It offers reliable, continuous operation, backed by a comprehensive protection system and an emergency power option, making it a safe choice for commercial, industrial, and public address applications.

Main Features

Solid Power of 360W
It delivers 360 watts of RMS power, more than enough muscle to power a large number of speakers in background music systems, public address announcements or ambient sound in large venues.

Versatile Outputs: 100V and 8 Ohms
Equipped with high-impedance outputs (100V line) for long cable runs and connecting multiple speakers in parallel, and a low-impedance output (8 Ohms) for connecting conventional speakers. This duality offers great flexibility in designing any sound system.

Simple and Effective Connectivity
It features an unbalanced stereo line input with RCA connectors to receive the signal from a preamplifier or mixer output. Additionally, it includes an RCA line output (Loop Thru) that allows the same signal to be sent to other amplifiers in a daisy chain, facilitating modular system expansion.

Integrated Protection Systems
To ensure maximum reliability and protect both the amplifier and connected speakers, the PRS360 incorporates protection circuits against overheating, overload, and short circuits.

Emergency Operation with 24V Battery
A crucial feature for security and evacuation systems. The unit has an input for a 24V DC power supply (battery not included), ensuring that the public address system remains operational even during a main power outage.

Professional Rack Design
With a standard 19-inch form factor and a 2U height, the PRS360 integrates seamlessly into any professional rack cabinet. The front panel includes an input gain control (master volume) and LED meters for visually monitoring the signal level.

Benefits for the Installer and the User

• Cost-Effective Scalability: Allows you to expand the power of an existing sound system economically, by adding zones or more speakers without the need for an investment in a new central mixer amplifier.
• 24/7 Reliability: Its advanced protections and backup power option make it a robust and reliable piece of equipment for installations that require uninterrupted operation.
• Simplified Installation: Thanks to its standard RCA connections and clear speaker terminals, setup is quick and straightforward for any installer.
• Clear and Powerful Sound: With a frequency response optimized for voice and music and low harmonic distortion, it ensures that announcements and background music are reproduced with clarity and quality.

Use Cases

The PRS360 booster amplifier is the perfect choice for a wide variety of medium and large-sized installations, such as:

• Large Stores and Shopping Centers: To expand the background music and announcements system to new stores, corridors or parking areas.
• Industrial Buildings and Warehouses: Ensuring that pager calls and security alerts are heard clearly in noisy and expansive environments.
• Educational and Sports Centers: Providing additional power for speakers in hallways, classrooms, gyms or outdoor areas.
• Hotels, Restaurants and Office Buildings: To extend ambient sound or public address systems to multiple floors or separate areas.

Frequently Asked Questions

Can I use this amplifier independently?
No, the PRS360 is a power amplifier or "booster". It needs to receive a line-level audio signal from a preamplifier, a mixer, or the preamplifier output of a mixer-amp (such as those in the Power Dynamics PRM series).

What type of line input and output connectors does it have?
It uses standard RCA connectors for both line input and line output (loop through), making it easy to connect to most commercial audio equipment.

Is it complicated to install it in a 19" rack cabinet?
No, it's very easy to install. It comes with the necessary rack mounts (ears) and occupies a standard 2U rack space.

What is the 24V power input for?
It is used to connect a backup power source, such as a 24V battery system. This ensures that the amplifier continues to function in the event of a mains power failure, which is essential in emergency and evacuation systems.
