Sherbourn 5/1500A Five-Channel Amplifier
Best powerful amplification for discerning home theater enthusiasts.
The Sherbourn 5/1500A is a five-channel power amplifier designed for home theater systems. It delivers robust performance, with individual channels capable of producing significant wattage into various impedance loads. For instance, when driving 8-ohm loads, one channel can reach 0.1% distortion at 181.3 watts and 1% distortion at 210.2 watts. When connected to 4-ohm loads, these figures increase to 317.1 watts at 0.1% distortion and 356.4 watts at 1% distortion. The amplifier exhibits a wide frequency response and low total harmonic distortion plus noise (THD+N), ensuring high-fidelity audio reproduction. Its signal-to-noise ratio is also impressive, particularly when using the XLR input, contributing to a clean and dynamic listening experience.

Know before you buy
The amplifier features both input types, but the XLR connection offers a superior signal-to-noise ratio of -98.43 dBrA compared to -90.25 dBrA for RCA. If your processor or receiver supports balanced outputs, XLR is the recommended choice for a cleaner, quieter audio signal.
Yes, the 5/1500A is designed for high-current output and handles 4-ohm loads effectively. It is capable of delivering over 300 watts per channel into 4-ohm loads, making it a strong match for speakers that require significant power to perform their best.
Yes, the unit features a rack-mountable design, making it a practical choice for dedicated equipment racks. It also includes extensive heatsinking to manage thermal output during extended use, ensuring consistent performance in enclosed spaces.
The integrated anti-clipping circuitry is designed to prevent harsh distortion when the amplifier is pushed to its limits. It helps maintain a clean, dynamic sound profile even during high-volume passages, protecting your speakers and ensuring a more enjoyable listening experience.
Yes, the 5/1500A includes auto signal sensing. This allows the amplifier to wake from standby mode automatically when it detects an incoming audio signal, providing a seamless experience for your home theater system.
When all five channels are driven into 8-ohm loads, the amplifier maintains a robust output of approximately 175.6 watts per channel at 0.1% THD+N. This ensures that even in complex multi-channel scenes, your system retains significant power and headroom.
