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.
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.
