Biamp SPA-GSQ100

The Biamp SPA-GSQ100 is a professional 4-channel power amplifier delivering 100W per channel into 4Ω or 8Ω loads, or 100W per channel at 70V/100V for high-impedance distributed audio systems. Its Class D topology ensures high efficiency and low heat dissipation, enabling fanless convection cooling for silent operation in noise-sensitive environments. The amplifier integrates seamlessly with TesiraFORTÉ X DSP systems via Ethernet, providing remote control and monitoring. With a total output of 400W in a compact 1RU chassis, it is ideal for corporate AV, education, hospitality, and performance venues requiring reliable, high-quality audio amplification.

Advantages

The SPA-GSQ100 offers exceptional audio fidelity with a frequency response of 20 Hz to 20 kHz (±0/-1.5 dB) and THD+N below 0.1% across the full power range. Its high signal-to-noise ratio (>100 dB A-weighted) ensures a clean, noise-free signal path. Fanless convection cooling eliminates mechanical noise, making it suitable for boardrooms, theaters, and recording studios. The amplifier supports both low-impedance (4Ω/8Ω) and high-impedance (70V/100V) outputs, providing flexibility for a wide range of speaker configurations. Comprehensive protection circuitry guards against over-current, over-temperature, DC offset, and short circuits, ensuring long-term reliability. Integration with TesiraFORTÉ X allows advanced DSP control, including level, mute, and fault monitoring over the network.
