LX 1600 Test in `Production Partner` 11/2008

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.
