Introduction

Dear audio friend and audio technician.

Congratulations on your decision to use Hoellstern amplifiers. First-class tools are a solid foundation for professional 

audio productions. 

The ASID GmbH located near Freiburg designs, produces and distributes the Hoellstern amplifiers. It is our 

philosophy to supply top-quality audio products. 

Hoellstern amplifiers present modern, efficient amplifier technology in combination with efficient, strong switching 

power supplies. The technical dimensioning and the circuit design are based upon criteria from the aerospace and 

automotive industries. Together with an uncompromising circuit layout and high-quality components the result is a 

top-grade audio product. Only the quality of our products and the resulting customer satisfaction have the highest 

priority for us.

Hoellstern amplifiers meet numerous requirements, from the viewpoint of a sound engineer and also of a buyer:

x

Performance, sound, size and weight 

x

Features, operation and flexibility

x

Reliability, stability of value, cost effectiveness

Please take your time to read the manual attentively prior to putting the unit into service. This way you will become 

familiar with the technical details and use the amplifiers optimally. For permanent installations we ask you to solicit 

further information from us if needed. 

Please do observe all safety notes before bringing the unit into operation!

Please take care of your amplifiers, aspirate the air filters regularly and make sure the amplifiers are mounted 

correctly. Every additional warming by 10 Kelvin will typically halve the service life of electronic components.

We wish you much success.

ASID GmbH
