4 - PMS USER’S MANUAL
1. INTRODUCTION
In purchasing the XXL PMS, you have acquired a professional monitoring system and a
powerful headphone power amplifier of the high-end class, which meets all the demands
and requirements of studio and live works. In fact it is an extremely efficient and
universal headphone amplifier that can drive headphones from 8 to 600 ohm and more.
It has been designed above all to deliver great power and to be a reference unit for the
live and studio works. It is also a powerful manager for powered stage monitors for
musicians in the studio or in the stage.
1.1 High Technology
Our experience in the field of professional live and studios drove us to design the PMS,
an incredible small size personal monitoring system with integrated Headphone power
amplifier that is able to give answer to all the demands in Studio, Live, broadcast and
TV applications. All the electronics is assembled directly on PCB with no wire use; it
means less possibility of malfunction. All the internal IC are 4580, ultra High quality
Operational Amplifier that allow high current output with very low noise threshold. All the
outputs are protected in order to guarantee safe operating conditions in every situation.
All the inputs are balanced, and a high quality audio transformer (optional) on every
inputs can be easily installed; in this way you can have the best matching conditions
with the other units. The choice of external power supply use, ensure
professional features with minimum noise, and allow you to drive the unit also with an
external optional battery pack so that you can use the unit also without the presence of
main power AC.

your headphone set. Turn down the LEVEL controls before
you switch on the unit.
