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.
