Zapco ST-501D SQ MINI Mono Class D Mini Amplifier

The new Class D Studio MINI Amplifiers.

Over the last couple of years Zapco has introduced more than our pure high end SQ Competition amps. We have also introduced a line of great sounding amps in an affordable price range called the Studio series. The Studio D amps are full range Class D amps with great sound, a compact chassis, and more crystal clear power than the competition.

​

Thanks to a brand new technology, we are able use the NXP Class D solution to get amazing power and performance in a incredibly compact chassis with over 90% efficiency. And this diminutive little beast has all the features of the larger amps... and optional HD Bluetooth streaming!

The HD Bluetooth Module (optional) is a Qualcomm CSR8675 premium tier single-chip solution with 120 MHz DSP, delivering high quality 

wireless audio performance over Bluetooth and aptX HD making it an ideal choice for premium audio products.
