Product information "QPRO Audio QLM 2.4N Digital loudspeaker controller 2in/4out"

the QLM-Series are powerful DSP based loudspeaker management system, ideally suited for install and rental application, where outstanding sound quality and a remote control software with extensive functions is needed.

The QLM-Series has two devices with 2IN - 4 Out channles and 4 In - 8 Out channels.

Each output has a gain control, variable delay, highpass and lowpass crossover filters, seven band multi-type filters, polarity, input signal source an limiter. The crossover filters offer stopes of up to 48dB/Octave.

Each input has a gain control, variable delay, multi-type filters, Filter type included parametric equalisation, high & low shelving, notch, band-pass, all-pass, variableQ highpass & lowpass.

The internal structure allows completely flexible routing of any output from any combination of inputs.

Beside the normal possibliity to store and load q preset, the QLM-Series also provides a unique storage function where it is possible to store and load single speakers. This allows to combine any speaker from our QPRO datebase together.

For remote control the QLM-Series providea USB, and RS 485 port.

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!
