Dynacord Professional Power Amplifiers Front Panel, Rear Panel, Dynamic Limiters, Lpn + Lo-Cut

LX Series

Were they to appear in a high-end hi-fi magazine, the measured values of the LX1600 would no doubt have the audiophiles drooling. From every single discipline it’s evident that the people working in Dynacord’s development department in Straubing are perfectionists in the best sense of the word.

FRONT PANEL

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.

REAR PANEL

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 as well as the Bridged Out are on Speakon connectors.

The signal of Output B is additionally available on pins ±2 of Output A, so that with 4-pin wiring a two-way system can be driven. A Ground Lift switch is also pro- vided to separate the chassis ground from the signal ground in order to eliminate ground loop hum.

DYNAMIC LIMITERS

Dynamic limiters are general components in all DYNACORD power amplifiers. High-speed 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.

LPN + LO-CUT

The retrofittable NRS 90268 kit, which is available as an option for all LX power amplifiers, combines the 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 full-range speakers and thereby considerably extend the repro- ducible range at the bottom end. The acoustic result is bass reproduction with more punch and greater substance.
