Introduction - DIGAM Q 3002 Bedienungsanleitung

Introduction

Powersoft is a leading company in the field of high efficiency audio power management. The totally
new Powersoft's DIGAM (DIGital AMplifier) technology has changed the way the world looks at
professional audio amplification. No other amplifiers come close for applications demanding high
power and long term reliability.
Thanks to amazing reductions in heat output along with reductions in weight and the characteristic
high output power, DIGAM amplifiers can be used in an unlimited range of applications such as
concert touring, opera houses, theatres, churches, cinema, theme parks, television sound stages
and industrial applications.
More sound and less weight
Compared to a conventional amplifier, Powersoft DIGAM technology offers very high efficiency and
delivers more power to the loudspeakers with much reduced heat dissipation. This greater efficiency
enables dimensions, weight and power consumption to be reduced. The output stages of the
amplifiers typically run at 95% efficiency, dissipating only 5% of the input energy as heat.
One of the most interesting characteristics is that DIGAM's efficiency is almost independent of output
level. Conventional amplifiers achieve their best efficiency only at full rated power output. Since
standard music has an average power density of 40% of the maximum level, conventional amplifiers
can easily generate 10 times more heat than DIGAM for the same volume of sound.
Superior Sound-Sonic Accuracy
Crystal-clear highs, and a tight, well-defined low end: the most accurate reproduction of an audio
signal. Patented design features ensure very high performance in parameters such as distortion,
frequency response, slew rate, power bandwidth and dumping factor.
Totally Digital with High Reliability
The DIGAM series is based on PWM technology that has been used for 30 years or more in power
supplies and inverters. PWM provides high reliability, small size, low weight and high efficiency. A
PWM converter works as a high frequency sampler, converting the variable amplitude (audio) signal
into an impulse sequence with average value equal to the audio input.
DIGAM amplifiers use very high sampling frequencies to obtain high performances across the audio
band. Powersoft holds several patents on the DIGAM technology.
The Best Amplifier for Your Mains
Powersoft is the first amplifier constructor to use power factor correction. This unique feature
ensures that a predominantly resistive load is presented to the mains power supply, minimizing
current distortion and voltage/current displacement This leads to much improved performance of the
amplifier at high levels of output and avoids
switching power supplies. Another great advantage of this technology is that its performance is, to a
large extent, independent of the mains voltage. The rated output power does not vary with load/line
conditions.
The Show Always Goes On
DIGAM Series is completely protected against every possible error in operation and is designed to
work under every condition. It gives you maximum power with maximum safety and increases long-
term reliability. Anticipating potential problems at the design stage means your show always goes
on!
