Get ready to experience the incredible power amplification of our state-of-the-art Class H design!

The SQ-series offers an amazingly wide range of very cost-efficient, flexible amplifier performance! From 2x900@4Ohm up to 4x1200@4Ohm, seven different models are available for your choice! The Class H output stage is powered by an oversized analog power supply with a strong toroidal transformer, ensuring stable performance even under weak or unstable mains supplies. The front panel is equipped with a power switch and several LEDs to display the working status, making it easy to monitor the amplifier's status.
