NTRODUCING THE

DN9848

The DN9848 is a highly configurable, digital electronic cross-over/loudspeaker management system
comprising four balanced analogue input channels and eight balanced analogue output channels. Its

unrivalled routing flexibility enables each output to be sourced from a single input, a pair of inputs, or

all four inputs.

Each input channel features:

12 separately configurable, fully parametric equalisation stages that

may be used for room equalisation

  A programmable delay of up to 1000ms
  Gain control
  Full range compression

Each output channel features:

Configurable high and low-pass filters for setting the cross-over characteristics
Six stages of fully parametric equalisation that may be used to

compensate for system or enclosure characteristics

  Delay of up to 300ms on each output, mainly used for system time alignment
  Gain control and output muting
  Full range compression and full range limiting
  Dual all-pass phase correction sections, the first of which can be any of the

filter or parametric EQ stages and can be adjustable in 5 degree steps

The cross-over filter may be chosen from the following types:

  12dB/oct and 24dB/oct peaking (high-pass filter only)
  Butterworth (6, 12, 18, 24, 36 and 48dB/octave)
  Linkwitz-Riley (12 and 24dB/octave)
  Bessel (12, 18, 24, 36 and 48dB/octave)

Channel programming can be performed directly from the front panel controls or remotely using the

associated Stardraw software application or Smaart real-time analysis software (via the RS-232 PC

Port or RS-485 COMMS connectors). If required, access to critical parameter menus can be password
protected, e.g. to avoid unauthorised adjustments in hire installations.

Commonly used settings can be stored for repetitive use in up to 32 lockable System memories while

varying show settings can be stored in up to 5 User memories. Also 99 Presets can be stored in non-

volatile Flash memory, including up to 25 available Factory Preset cross-over set ups for commonly
used Electro-Voice loudspeaker systems.

Klark Teknik has a policy of continuous development and may produce updates to the DN9848 host

code. These can be downloaded to the unit via the front panel PC Port. To keep up with newest
