NTRODUCING THE
DN9848E
The DN9848E is a highly configurable, digital electronic crossover/loudspeaker management system
controller comprising four balanced AES/EBU digital input channels and eight balanced analogue
output channels. Its unrivalled routing flexibility enables any amount of any input to be routed to any
output.
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 crossover 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 five-degree steps
The crossover 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 from a PC
using the associated Elgar software application via the real panel Ethernet comms connectors (or
RS-232 PC port on the front panel). If required, access to critical parameter menus can be password
protected, for example, 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 five User memories.
In addition, any input or output channel’s parameters may be copied across channels, and channels
may be ganged to link source and destination channels for ease of operation.
Klark Teknik has a policy of continuous development and may produce updates to the DN9848E host
code. These can be downloaded to the unit via the front panel PC Port. To keep up with latest
