Product information "QPRO Audio 4 channel amplifier 1HE 4 x 3000W/2Ohm"

The - eries amplifiers are -QLP S digital four channel amplifiers with power factor correction technology.

All QLP models have a very high-efficient switch mode power supply, which ensures best and stable

performance even at full power.

Our digital amplifier msv technology, together with the use of best selected electronic components allows the 2 Ohm

use of all four channels at same time with a maximum power of 4 x 3000 watts, packed in a lightweight and

compact size of 1U.

The QLP-Series is equipped with a switch msv on the back panel to adjust the Input gain to 29dB, 32dB, 35dB and

38dB to match with other devises.

Four SPEAKON outputs are mounted at the rear side. The SPEAKON connector of the output channel A (1+/1-) is

connected with all four poles and offers the output signal of channel B at the pins 2 (+/-). Channel C + D is

equipped with the same wiring. This four-pole connection makes it easy to connect a Sub / Sat system with one

cable only.

The QLP-Series can be switched into msv stereo, mono and bridge mode. In mono mode the input signal from

channel A is linked to the output channel A + B, and input C is linked to output C + D. In bridget mode the

connection is 1+/2- on output A and output C. The Clip limiter can be switched On/Off on all channels.

OUR FEATURES. All those systems share some features worth being mentioned explicitly. Decisive features when intending to buy sound reinforcement equipment. Important features for us, the loudspeaker and amplifier designers. Features appreciated by yourself and the audience, even after years of use. Some of those features make us unique.

THE HUMAN FACTOR. It is the ear, your ear, the decision for a certain loudspeaker depends on. A diagram – be it ever so impressing – is merely a graphical representation of what we hear. Thus, we keep completing all our technical tests by listening to the sound produced. Professionals of all fields of expertise thoroughly examine each product. Their well-trained hearings detect what may have escaped our notice just viewing metering data and curves.

THE CRAFT FACTOR. The single parts of our sound reinforcement systems are professionally assembled in our workshops. People working here know their business. Genuine craftsmen.

That’s why each system leaving our workshops is a high-quality product.

THE EXPERIENCE FACTOR. Beside all technical equipment like the most modern simulation tools

and acoustic – electronic measurement systems, the experience in research, development and manufacturing of professional audio products is the key for a perfect product.

Our team is always there to support you and give you answers and solutions.

We look forward to do something great together.

Let’s share some ULTIMATE EXPERIENCE OF SOUND!
