SL Series
soliD all-rounDers at a competitive price
The level controls on the front are calibrated in dB
and recessed into the front panel to guard against
mechanical damage. The easy-to-read LED display with
its Power, Protect, Signal and Limit indicators offers
a quick overview of the operating state of the power
amplifiers.
lpn-filter
The switchable Low-Pass Notch (LPN) filter is a typical
DYNACORD special feature. This filter circuitry
corrects the frequency response and optimizes the
transient behaviour of loudspeakers. The resulting
dynamization cannot be achieved with any graphic
or parametric equalizer or ‘bass booster’, since the
way the LPN operates is based to an important extent
upon a dynamic optimization of the slew rate of the
signal. The switch allows you to compare the acoustic
difference with and without the LPN. The whole
signal becomes much more powerful and voluminous.
The effect is particularly noticeable with small to
medium-sized full-range loudspeakers but also with
applications featuring subwoofers.
The electronically balanced XLR IN / OUT sockets are
provided for direct operation with professional mixing
consoles and signal processors. All the models in the
SL 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 provided to
separate the chassis ground from the signal ground in
order to eliminate ground loop hum.
