Weighing 8.15kg, the amplifier, which is two rack units in height, is rated at 2 x 1100W. The secret of its compactness lies in the combination of a switching power supply with Class H technology; Dynacord's developers have succeeded in combining the headroom advantages of a transformer power amplifier with the considerable savings in weight you get with a 'chopper' power supply.
LX Series power amplifiers are robust and will take the bangs and bumps that are part and parcel of life 'on tour' without compromising their reliability. With the full panoply of protections against overheating, overloading, short circuit, HF, DC etc, they also resistant to the bugbears that can jeopardize the longevity or performance.
Another safeguard is provided by the Soft Start relay system - a power-up delay to protect the power outputs and also limits current flow to reduce the risk of blowing a fuse in the mains power supply.
Dynacord LX power amplifiers are equipped with ultra-high-speed audio processors that compare the output signal to the input signal and are capable of sending fresh control parameters to the limiter in the event of non-linearity. The limiters are dynamic and act not only upon the dynamic range but also upon the input level.
Further features of the Dynacord LX 2200 include; thermic stability guaranteed by two 3-speed fans (fast/slow/off) that are extremely silent in their operation, electrically balanced inputs on XLRs and direct outs provided as standard, parallel (mono) and dual (stereo) input routing modes, easy-to-read display including power, protect, signal and limit LEDs, 32 dB constant gain, Speakon connectors at the power outputs (channels A and B) as well as the bridged out, guaranteed operating security with loads of up to 2 ohms in normal mode and up to 4 ohms in bridged mode, rackmount rails are also available for cabinets and transport racks.
