ESX QUANTUM Digital 2CH AMP QS-TWO-ISO
Amplifier
Why choose this product?
Following the resounding success of the sensationally small 2-channel QS-TWO amplifier (only 90 x 35 x 70 mm), ESX set out to develop an equally small but powerful 4-channel version. With the brand-new QS-FOUR , this ambition has now become a reality: The ultra-compact 4-channel amplifier is available immediately – and only 10 mm wider than the 2-channel model. Delivering an impressive 4 x 60 watts RMS in a mere 90 x 35 x 80 mm, it sets new standards in the field of nano-amplifiers.
