With the LX 2200, DYNACORD is introducing a new class of professional high-end amplifiers: the Switch Mode Precision series.

The combination of an analogue class-H design with a state-of-the-art switching power supply has made possible the creation of a professional power amplifier, delivering up to 2 x 2100 watts into 2 ohms and excellent audio specifications, that weighs only 8.7 kg. Even complex loads as low as 2 ohms can be driven with absolute reliability. Amp racks containing several LX power amplifiers for active multi-way use are therefore easy to manipulate.


With this technology, two different power supply rails are permanently available internally to the power amplifier blocks. For most of the program material, the lower operating voltage is able to reproduce the audio signal flawlessly; however, as soon as there are dynamic peaks, the amplifier switches internally and at high speed to the higher supply voltage. Since for long periods the power amplifier blocks are operating with the lower supply voltage, there is considerably less power dissipation than with conventional class AB power amplifiers, which also means considerably less waste heat.


Dynamic limiters are general components in all DYNACORD power amplifiers. Highspeed audio processors are continuously comparing the input signal to the output signal, and in the event of any non-linearity, the processors send control signals to the limiters, which operate dynamically upon the input level. As a result, the THD all the way up to 21 dBU is limited to an inaudible 1% max at the output.


The retrofittable NRS 90268 kit, which is available as an option for all LX power amplifiers, combines the patented LPN (low-pass notch) filter with a low-cut filter. These eliminate transient non-linearities in the low frequency range in small to medium-sized fullrange speakers and thereby considerably extend the reproducible range at the bottom end. The acoustic result is bass reproduction with more punch and greater substance.


The dB-calibrated level controls are implemented as ultra-precise detent potentiometers that are recessed in the front panel to protect them from accidental contact. Power, Protect, Signal and Limit LEDs provide a quick overview of the operating status.


The electronically balanced XLR IN / OUT sockets are provided for direct operation with professional mixing consoles and signal processors. All the models in the LX series are designed for a Constant Gain of 32 dB. The power outputs for Channels A and B are on Speakon connectors. AGround Lift switch is also provided to separate the chassis ground from the signal ground in order to eliminate ground loop hum.


With a stable output of 2 x 1600 watts into 2 ohms and 2 x 1100 watts into 4 ohms, this is the ideal amplifier for professional multi-way components as well as mediumsized subwoofers in concert sound systems.

SAFETY PACKAGE The complete LX series is equipped with protections against overheating, overloading, short-circuits, DC and HF as well as a Back-EMF protection. With the Soft Start system, the power outputs are switched on via a relay when a safe operational state has been reached and a power-up delay prevents the mains fuses being activated.
