Introduction
The DN9824 is speaker processor that provides 2 inputs and 4 outputs, plus internal summing of the
inputsAand B. Via a matrix, it is possible to assign any output to any input or to the sum of the inputs. It
is further possible to establish the following configurations: Stereo or Dual 2-way systems, 3-way +
Direct and 4-way systems, each with Mono Sub-channel, and also full range systems.
Providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115dB, the
DN9824 sets new standards for digital loudspeaker controllers and processors. TheAD section uses 64
times oversampling, gain-ranging Sigma-Delta converters. The DA section uses 128 times
oversampling Sigma-Delta converters. The overall signal processing is performed by two 24-bit
Motorola DSP56007 signal processors.
Each input incorporates a 7-band equalizer, allowing the user to assign high and low-cut, high and low-
shelving or parametric peak-dip filters to each of the individual filter sections. Master delays are
located in each of the input channels, which can be adjusted to affect INA, INB and INA+B.
High-pass and low-pass filters are provided for the frequency crossover functions in all operation
modes. The selection includes Linkwitz-Riley, Butterworth and Bessel type filters with switchable
slopes (slopes are dependant on filter type) between 12, 18 and 24dB/oct. Also available are 6dB/
octave and 12dB/octave peaking filters.
Six additional EQ filters are included in each output channel. Each can be set by the user to function as
high-pass or low-pass, high or low-shelving, parametric peak-dip or all-pass filters. Each channel
additionally provides a delay, a polarity switch, a programmable level control and a digital
compressor/limiter with adjustable threshold, attack and release.
A total number of 70 memory addresses, (50 preset and 20 freely assignable user programs), are
available.
Additional features are:
- FLASH memory for software and preset updates via serial interfaces.
- PC-based operation and configuration software running under Windows '95 / Windows '98
- Standard MIDI-interface
- RS-232 interface
- Back-lit graphic-display with 122 x 32 pixels
- Inputs and outputs are electronically balanced, XLR-type connectors
- Transformer-balancing for the inputs is optionally available
- Input/Output level controls, Output Mute switch, and channel function indicators SUB, LO,
MID and HI
- Input/Output level meters, limiter and clipping LEDs
Within this owner's manual, many of the DN9824's extensive features are explained in detail. For a
complete understanding of its operation, please take the time to carefully read the manual. Keep the
manual stored at a safe place to have it at hand for any further reference.

Important Notes
Installation
Cables
Protection
Refer to the Technical Spec for supply voltage range and fuse rating.
To prevent any trouble or problems occurring from high temperatures inside the appliance, it is
advisable not to use the DN9824 in environments where the ambient temperature exceeds 40°C. It is
also important to provide sufficient air-flow around the unit.
It is not recommended to install or operate the DN9824 directly above or below any device that
generates a large magnetic field; e. g. power amplifiers.
For best results, the unit should be operated using balanced inputs and outputs. In this configuration,
the non-inverting conductor (+) of the cable needs to be assigned to pin 2 of the XLR type connector,
while the inverting conductor (-) is assigned to the connector's pin 3. The shielding has to be connected
to pin 1. If the input channels have transformers for galvanic isolation, the cable screen should not be
connected to the ground plain of the transmitting device.
It is also possible to operate the appliance in unbalanced input/output configuration. In this
configuration , the cable's "HOT" conductor must be connected to pin 2 and the screen to pin 1 of the
XLR connector. To prevent a 6dB level attenuation, the user must short-circuit pins 1 and 3 of the XLR
connector. On the other hand, if this measure leads to interference noise, removal this connection is
recommended.
Note - To prevent loss of higher frequencies, it is recommended that audio cables should not exceed
10m.
CAUTION: TO REDUCE RISK OF ELECTRICAL SHOCK OR FIRE, DO NOT REMOVE COVER.
NO USER SERVICEABLE PARTS INSIDE.
DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING: THIS EQUIPMENT MUST BE EARTHED.
If the unit is subjected to extreme fluctuations of temperature, e.g. from being transported from outside
into a heated room, condensation may form. The unit should not be switched on until it has reached
room temperature.

Rotary controls set the input levels of the inputs A and B. The input signal can be
amplified by up to 6dB (input level control set fully clockwise) or attenuated to -
(input level control set fully anti-clockwise). Set the level as high as possible, without
clipping, to achieve the highest possible Signal to Noise ratio.
The level meters are for the user to monitor the input signal levels. They individually
indicate the corresponding peak value of each input signal. The input level control
should be set to a position such that the meters indicate a level between -6dB and -12dB.
To prevent internal clipping, ensure that the clip LED's are not lit. Three different meter
indication modes can be selected in the OPTIONS menu, "Normal fast", "Peak Hold" or
"Slow Decay".
In the PLAY mode (normal operation), the 32 x 122 pixel LCD shows the number and
name of the program and the current active configuration. In EDIT mode, the display
shows individual function blocks including their corresponding parameters and
parameter values. Additionally, and depending on the chosen mode, the display also
indicates option menus, status messages, etc..
This key allows the user to enter the EDIT mode. While in PLAY mode, press the EDIT
key, the last modified parameter of the active program is displayed. Using the SELECT
( or ) keys gives the user the facility to select (highlight) the next or previous
parameter in the displayed function block. The value of the highlighted parameter can
be altered by using the rotary PARAMETER encoder.
While in PLAY mode, press ENTER, then pressing the SELECT key will select the
next program in the program list. While in EDIT mode, pressing the SELECT key
selects the next parameter within the displayed function block. While in OPTIONS

Press the ENTER key, and rotating the PARAMETER encoder selects a program. Press ENTER again
to activate the desired program. In EDIT mode, the encoder is used to alter parameter values or scroll
through function blocks. For further details, please refer to the chapter called "Operation".
These rotary controls are used to set the levels of output channels, allowing the user to match the
DN9824 to the input levels of the following chained devices. Correctly setting these controls results in
an improved Signal to Noise ratio. In most cases, good results are achieved when setting the controls to
their center detented position (-6dB). The digital output gain control (accessed in each output menu)
should be used only when higher output levels are needed. It is not recommended to use the digital
output gain control for large attenuation, since this would reduce the dynamic range of the D/A
converters.
These rotary controls also provide push key functionality, which, in the EDIT mode, allow the user to
switch between the same function block in different output channels.
These keys allow the user to mute the output signal of the corresponding output. Pressing a key once
switches the mute function ON, and the key's red LED lights. Pressing the key again switches the mute
function OFF and the key's LED is switched off.
These LED's indicate which frequency band each channel is set to. If a channel is configured for full
range operation, all of its' function LED's are lit simultaneously.
These meters indicate the peak level of the corresponding output. The DN9824 should be operated at a
level such that the clip LED's are not lit, as this could indicate internal clipping. The meter response can
be set to "Peak-Hold", "Normal fast" or "Slow Decay" using the OPTIONS menu.
The LIMIT LED's light when the compressor/limiter of the corresponding channel is activated; e.g.
when the audio signal level exceeded the previously set threshold and, therefore, the output level is
compressed or limited.

Operation
PLAY mode (normal operation)
At power on, the unit enters PLAY mode. The display shows the number and name of the last user
program to be used
To recall a program memory, press the ENTER key and step through the available program memories
using the SELECT ( or ) keys or the rotary PARAMETER encoder. At the selected memory, press
the ENTER key again. The user will be asked to confirm whether this is the required program. If so,
press ENTER key again to confirm.
Press the ENTER key to confirm and
recall the new program.
Recalling a factory preset (program memories F01 to F50) provides the easiest method of achieving
good results with the DN9824. Factory preset programs are carefully designed, and are stored,
internally, in non-volatile FLASH memory. The required loudspeaker combination can be selected
from the list of factory presets and the DN9824 will automatically set the optimum parameters for the
chosen components. To apply changes to a factory preset, it first has to be copied to a user-definable
preset location (U01 to U 20) and the name changed to make it unique (For further information refer to
chapter called STORE mode).
Possible configurations for the DN9824 are:-
- Stereo 2-way. The parameters of the inputs A and B and the Low and High outputs are
simultaneously set to identical values.
- Dual 2-way. Input and output parameters can be set separately from each other.
- Mono 3-way with Direct Out (3-Way Sub + 1). The sub channel, as well as the Direct
Out, can be assigned to IN A, IN B or to the summed, monaural signal of the two input
channels.
- Mono 4-way. The sub channel can be assigned to IN A, IN B or to the summed,
monaural signal of the two input channels.
- Full range. All outputs can be freely assigned to IN A, IN B or to a summed, monaural
signal of the two input channels.
34
NOTE: If the new program is a different configuration to the
last, the user will be asked to confirm change of configuration.
EDIT mode
Enter EDIT mode by pressing the EDIT key. To exit the EDIT mode, press EDIT again.
When in EDIT mode, use the SELECT ( or ) keys to highlight (light text on black background) the
function block title at the top of the display. Use the rotary PARAMETER encoder to scroll through
function blocks until the desired function block is selected for editing. Use the SELECT ( or )
keys to highlight the parameter for editing and then use the rotary PARAMETER encoder to change the
value/text of that parameter. When a parameter has been changed, a flashing "E" appears in the top
right corner of the LCD, informing the user that the selected program is being edited but has not been
saved.
The user now has different options to continue:-
- To store the edited program, see STORE mode. When stored, the flashing "E" will
disappear.
- To continue altering the parameter values, continue as above.
- To return to the original (unedited) program, press ENTER and enter the program recall
process. This cancels the EDIT function and discards the parameter value changes of the
selected program.

Each input channel of the DN 9824 has 7 bands of parametric EQ. Each band can be set up to be one of
the following EQ function blocks.
describes the selected filter type. When selecting BYPASS, no equalisation effect is applied to
the signal. PEQ provides a parametric Peak/Dip Filter with programmable frequency, Q and gain.
LOSLV/HISLV are Low Shelving or High Shelving equalizers respectively. Their parameters are
frequency, slope, and gain. The parameters of the LOPASS/HIPASS filters are frequency and slope (Q
is only available with 12dB slope).
sets the center frequency of parametric EQ's and the cutoff frequency of LOSLV/HISLV and
LOPASS/HIPASS filters.
The value of the parameter determines the quality or bandwidth of parametric EQs. Higher Q values
result in a narrow banded filter while smaller Q values result in an increased bandwidth. The Q
parameter also describes the quality and, therefore, the graph of LOPASS/HIPASS filters.
sets the degree of amplification or attenuation of the parametric EQ or the low shelving and
high shelving equalizers. The stepwidth is 1 dB.
The parameter describes the steepness, or order, of the filter for the LOSLV/HISLV and
LOPASS/HIPASS equalizers.
