Delivering Sustainable Power to Every Speaker
In large-scale commercial and institutional installations, the audio amplifier is the workhorse that never rests. Traditional amplifiers often struggle with heat dissipation and high electricity costs, leading to premature failure and increased operational expenses. The SR-2500D Digital Class-D Two-Channel Amplifier solves these issues by utilizing high-speed switching power technology, delivering massive output in a compact, cool-running frame that is perfect for modern
professional conferencing solutions
The SR-2500D – High Efficiency, Low Footprint
The SR-2000D series, including the flagship SR-2500D, is built for the “green” boardroom. By converting nearly all its electrical intake into pure sonic power, it avoids the energy waste common in older Class-A/B designs.
85% Efficiency with Switching Power Technology
With a power efficiency of up to 85%, the SR-2500D generates significantly less heat . This thermal efficiency allows for a more compact design that saves valuable installation rack space. In advanced AV integration projects where multiple amplifiers are stacked together, the reduced heat output extends the performance life span of all the surrounding conferencing equipment, ensuring years of trouble-free operation.

Dual-Channel Versatility for Multi-Zone Audio
The SR-2500D is a two-channel unit, making it an incredibly cost-effective choice for multi-zone setups. It can drive two independent zones with different audio sources, or act as a high-powered stereo engine. This makes it ideal for corporate offices where you might need background music in the lobby and clear voice amplification in the boardroom simultaneously—all driven by a single piece of conferencing equipment.
Flexible Output Architecture: 100V, 70V, and 8 Ohms
Different audio environments require different wiring standards. The SR-2500D is engineered to handle them all.
Bridging Public Address and Hi-Fi Stereo
The amplifier features versatile loudspeaker outputs supporting high-impedance 100V and 70V lines . This is essential for public address systems where audio must be distributed over long distances to multiple ceiling speakers. Simultaneously, it supports low-impedance 8-ohm outputs, allowing it to drive high-fidelity stereo speakers for a premium musical or cinematic experience. This dual-capability makes it a staple for professional conferencing solutions.
Maximising Rack Space and Longevity in Advanced AV Integration
In modern server rooms and AV racks, space is at a premium. Because Class-D technology is so efficient, the SR-2500D can provide up to 500W of power in a chassis that is much lighter and smaller than its predecessors. This allows integrators to fit more power into fewer rack units, streamlining the advanced AV integration process and making the system easier to manage.
A Core Component for Video Conferencing Systems
While microphones and cameras get the most attention, the amplifier is what ensures the remote participants are heard with authority. By providing clean, undistorted power to the room’s speakers, the SR-2500D ensures that every word in an audio and video conferencing session is delivered with crystalline clarity, even at high volumes.

FAQs
What is the main benefit of "Class-D" over traditional amplifiers?
Class-D amplifiers use switching technology to achieve much higher efficiency (up to 85%). This means they consume less power and generate significantly less heat, making them more reliable and easier to install in compact racks for advanced AV integration.
Can I use the SR-2500D for both background music and announcements?
Yes. With its two-channel design and support for 100V/70V lines, you can use one channel for a public address zone and the other for a separate audio source, providing a versatile and cost-effective professional conferencing solution.
Does the SR-2500D support Hi-Fi speakers?
Absolutely. In addition to high-impedance outputs, the SR-2500D supports a low-impedance 8-ohm output. This allows it to drive high-fidelity stereo speakers, ensuring premium sound quality for music or audio and video conferencing.
How does the low heat generation impact my equipment rack?
Heat is the primary enemy of electronics. Because the SR-2500D generates less heat, it reduces the thermal load on your entire rack, preventing other conferencing equipment from overheating and extending the overall life span of your video conferencing systems.
What power ratings are available in this series?
The series offers a range of power options to fit your needs: 120W (SR-2120D), 240W (SR-2240D), 350W (SR-2350D), and 500W (SR-2500D). This ensures you can select the exact amount of power required for your specific advanced AV integration project.
