Product Summary
QPS Series products are high-performance, versatile power
amplifiers for both touring and install applications, using
sophisticated Class-HD topology with four single-channel
outputs or one/two bridged outputs, parallel or stereo for up
to 4 x 2500 W (QPS 10K) and up to 4 x 1500 W (QPS 6K) at
2 ohms. It features independent gain control, signal/clip and
faults indicators, channels A and C XLR output link, parallel and
bridge mode, and speakON output connectors. Three dip-
switches allow setting the maximum output voltage peak for
each channel among eight values. High-e!ciency heat sinks and
variable-speed fans can withstand the hardest heat conditions
ensuring great power output stability over time. High quality, low
distortion audio output, flawless reliability, and industry-standard
speakON connectors make QPS series electronics the hassle-
free solution for sound systems and permanent installation
applications.

RCF QPS Series – Four-Channel Professional Power Amplifier FAQs
What is the RCF QPS Series four-channel professional power amplifier?
The RCF QPS Series is a high-performance, four-channel professional power amplifier designed to deliver reliable and efficient power to professional loudspeaker systems. Alpha Audio specifies the QPS Series as part of engineered sound reinforcement solutions rather than offering it as a standalone retail product.
How is the QPS Series amplifier used in professional audio solutions?
The QPS Series amplifier is used to power multiple loudspeaker zones from a single unit. Alpha Audio integrates it into complete audio systems for cinemas, auditoriums, corporate offices, houses of worship, transport hubs, and large commercial venues, ensuring precise power distribution and system stability.
What makes a four-channel amplifier important in large sound systems?
A four-channel amplifier allows multiple speaker lines or zones to be driven independently, reducing the need for multiple amplifiers. This improves system efficiency, rack space management, and operational control. Alpha Audio uses four-channel amplifiers to design clean, scalable, and cost-effective audio solutions.
Which types of speakers work with the RCF QPS Series?
The RCF QPS Series is designed to work seamlessly with RCF professional loudspeakers, subwoofers, and line array systems. Alpha Audio ensures proper matching of amplifier power, impedance, and speaker configuration for optimal performance and long-term reliability.
Where are RCF QPS Series amplifiers commonly installed?
QPS Series amplifiers are commonly installed in fixed professional environments such as cinemas, mosques, auditoriums, conference centers, stadiums, airports, metro stations, and educational institutions across Pakistan where consistent, high-quality sound is required.
Does Alpha Audio sell the RCF QPS Series amplifier directly?
No, Alpha Audio does not sell power amplifiers as individual products. The RCF QPS Series is supplied, installed, and commissioned as part of a complete professional audio solution that includes system design, speaker selection, cabling, and calibration.
How does the QPS Series support system reliability and protection?
RCF QPS Series amplifiers include advanced protection features such as thermal protection, short-circuit protection, and load monitoring. Alpha Audio incorporates these amplifiers in mission-critical environments where reliability and continuous operation are essential.
Can the QPS Series be used in multi-zone audio systems?
Yes, the four-channel architecture makes the QPS Series ideal for multi-zone audio systems. Alpha Audio uses it to power different areas independently, such as prayer halls, foyers, corridors, and outdoor zones, all within a single integrated system.
Is the QPS Series suitable for 24/7 operation?
Yes, the RCF QPS Series is designed for continuous professional use. Alpha Audio specifies these amplifiers for venues that require long operational hours, such as transport hubs, airports, control rooms, and public facilities in Pakistan.
Who handles installation and system tuning of the QPS Series amplifier?
Alpha Audio’s professional engineering team handles amplifier installation, rack design, load calculations, testing, and system tuning. This ensures the amplifier operates efficiently and delivers consistent sound performance throughout the venue.
