Foreword
The K Sub 1801 dp is a multi-functional premium class subwoofer with an integrated digital ampli-
fier providing 2400 Watt power @ 4 Ohm (AES) and a DSP controller.
The 18” long-excursion neo-
dymium driver is powered by the integrated amplifier. An additional subwoofer (e.g. K Sub 1801)
can be connected to the SpeakOn parallel LS out connector. Various pre-configured presets and
level settings are available for selection.
The integrated DSP controller is based on the same operating principle as the stand-alone control-
lers HDLM 8 and DSP 2.6. A mere 0.8 ms latency (from analogue input to output) is achieved
through the use of a 96 kHz sample rate. The excellent signal to noise ratio is a further feature of
the DSP controller. Electronic simulation of a transformer balanced input provides additional pro-
tection against hum and buzz caused for example by external interference. High grade electronic
components from the industrial sector and first-class circuit design result in a robust device with
excellent audio characteristics and minimize disruptive noise.
The default state of the integrated DSP controller is the standard configuration as described in this
manual. Custom presets can be installed by the user, but must be programmed with the LPI (Loud-
speaker Programming Interface) by the manufacturer. The preset file is a custom audio file which is
simply played into the audio input of the controller. In this manner, individual configurations can be
created, for instance to accommodate the specific requirements of an installation project. Further-
more, should you ever be unsure as to the integrity of the DSP configuration of your controller, you
can obtain a fresh default file from SEEBURG acoustic line and re-install the original factory pre-
sets yourself. Efficient and intelligent limiter functions provide optimal protection without sacrificing
any of the potential of the system.
