SQ-Amplifier
Quick Link

SQ-Series Powerful | Reliable | Affordable

Power Amplification in state of art Class H design!

The new SQ-series offers a wide range of very cost efficient, flexible amplifier performance. From 2x900@4Ohm up to 4x1200@4Ohm 7 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. The performance is stable even under weak or unstable mains supplies. The front panel is equipped with a power switch and several LED´s to display the working status.
