Power Dynamics PRS240 - 100V 240W Line Booster Amplifier

Power Dynamics PRS240 - 100V 240W Line Booster Amplifier

The Power Dynamics PRS240 is a power amplifier, also known as a "booster," specifically designed to expand the capacity of existing 100V line-level audio systems. With a robust 240W RMS power output, this unit is the ideal solution when you need to add more speakers or cover larger areas without replacing the main amplifier. Its primary function is to receive a line-level signal from a preamplifier or the output of another amplifier (such as those in Power Dynamics' PRM series) and deliver stable, amplified power, ready to drive a large number of speakers in constant-voltage configurations.

Built with reliability in mind, the PRS240 is equipped with multiple protection systems that ensure safe and continuous operation. It incorporates protection circuits against overloads, short circuits in the speaker line, and overheating. In addition, it features a fan for active cooling. Its robust and functional design makes it perfect for integration into commercial and industrial installations, offering a professional and durable power boosting solution.

Main features

• 240W RMS Power: Offers considerable power to feed multiple speakers in large PA installations.
• Flexible Outputs: It has 100V line output options, ideal for long distances and multiple speakers, as well as an 8 ohm output for connecting conventional low impedance speakers.
• Comprehensive Protection Systems: Equipped with protections against overheating, overload and short circuit, ensuring the integrity of the equipment and the installation.
• Input Gain Control: Allows you to precisely adjust the input signal level for optimal coupling with the audio source and to avoid distortion.
• Emergency Power Input: Includes a 24V battery input (not supplied), which ensures the operation of the warning or background music system even during a main power outage.
• "Designed for 19" Rack": With a 2U height format and included brackets, it integrates easily and professionally into standard rack cabinets.
• Simple Connectivity: Uses RCA connectors for line input and screw terminals for speaker outputs, facilitating a quick and secure connection.

Benefits for the installer and the end user

For the professional installer, the PRS240 represents an efficient and cost-effective way to scale sound systems. Its compatibility with Power Dynamics' PRM series and other preamplifiers on the market simplifies the expansion of existing projects. The inclusion of comprehensive protections and the option for rack mounting streamlines installation and ensures minimal maintenance. For the end user, this amplifier translates into consistent and reliable sound coverage in all areas, from offices and shops to warehouses and educational facilities, with the added peace of mind of emergency power for critical situations.

Use cases

This amplifier booster is the perfect choice for increasing power in a wide variety of commercial and public installations. It is ideal for:

• Add new speaker zones in supermarkets, shopping centers and large stores.
• Expand the public address and announcement system in schools, colleges and universities.
• Reinforcing ambient sound in industrial buildings, warehouses and logistics centers.
• Increase sound coverage in hotels, restaurants, and office buildings.
• Enhance sound systems in sports centers and public spaces.

Frequently Asked Questions

Can I use the PRS240 as a standalone amplifier?

No, the PRS240 is a booster or power amplifier. It does not have microphone or mixer inputs. It needs to receive a line-level signal from a preamp, mixer, or the line output of another amplifier to function properly.

Is it only compatible with the Power Dynamics PRM series?

Although optimized to work with the PRM series, it can be connected to any equipment that provides a line-level output (Line Out) via an RCA connector.

Are rack mounting brackets included?

Yes, the equipment includes the necessary brackets for mounting it in a standard 19-inch rack.

What type of battery do I need for the emergency function?

An external power supply or battery system providing 24V DC is required. The capacity (Ah) will depend on the desired operating time.
