DN9848 Key Features

1. INTRODUCING 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
