The QLP - Series amplifiers are digital two 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 2 x 4760 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 (+/-). 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. In bridget mode the
connection is 1+/2- on output A. The Clip limiter can be switched On/Off on all channels.
