● INPUT-SECTION
The crossover SEC-203/SEC-304, with its 24 dB/oct. active
crossover filters, assigns most precisely the selected frequency
band to each loudspeaker. Input level controls with
peak display LED for stereo (2x) and mono (1x) operation
can be supplied and adjusted over rear-side XLR sockets
(balanced). By a selector switch, the desired mode (stereo or
mono operation) can be selected.
● STEREO-SECTION
At stereo operation, a high-level control without frequency
control as well as a mid-control (only SEC-304) and a lowlevel
control with frequency control from 60 Hz to 1.3 kHz or
from 600 Hz to 13 kHz (switchable) as well as a mute switch
are available for CH A and B respectively. The adjusted signal
can be put out over XLR sockets (balanced) on the rear
for high, mid and low respectively.
● SPECIALS
● The crossover SEC-304, made in 19˝ design with 1 RU,
further features a ground/lift switch on the rear in order to
avoid possibly occurring hum loops.
● The power supply takes place over an IEC power socket
on the rear side of the device. The power ON/OFF switch
is on the front side.

control, a mid (only SEC-203), a high-mid/low-mid (only
SEC-304) and a low level control with frequency control from
60 Hz to 1.3 kHz or from 600 Hz to 13 kHz (switchable) as
well as a mute switch are available. The adjusted signal can
be put out over XLR sockets (balanced) on the rear for high,
high-mid, low-mid and low respectively.
● SUBWOOFER-SECTION
Independently from the operation mode (mono / stereo), a
mono subwoofer section with frequency control, level control,
low-cut filter (switchable 15 Hz 18 dB/oct.) and mute
switch is additionally available. The adjusted signal here also
can be put out over a XLR socket on the rear side.
