Limiter Settings
In order to offer the maximum of protection, some factory presets of the DP2696 can be entered
with the fixed limiting device with 0 dBu, limiting the power to approximately 30 W in 8. It is then
essential to set the threshold according to your devices.
To do it :
▪with the front panel buttons
– Use "CH" button to go to the selected output
– Use the "Parameter" button to go to the Threshold parameter
– Adjust with the parameter knob.
▪with dedicated software
- Go to panel control of DP2696 (Device then Add Device Panel, select
DP2696, press enter)
- Open selected "Output" window (1 to 6)
- Setting Threshold is located at the bottom right and can be adjusted
from - 40 to +20 dBu The following table expresses the threshold
corresponding to the nominal output power provided by the amplifier.
Values for a standard gain of 26 dB
Assignment of the input signals towards output signals
▪with the front panel buttons
Limiter threshold : threshold (dBu) = 20 log (sqrt [Power (W ) x Impedance (Ω)]/0,775) amplifier gain (dBu). Also see Tecnare Technical paper.
- Use "CH" button to go to the selected output
- Use the Parameter button to go to the "source" function.

- Access to the choice of the source is in the first column of the table.
Connection to a computer
Connection RS232 Many laptops do not comprise a connection series RS232. It is then
advisable to use a converter USB towards RS232. We can provide an optional accessory USB
& RS232 interface or you can use a commercial interface. Unfortunately, few converters meet
the requirements to perform correctly with the DP2696. The converters must be equipped with
chips FTDI or Prolific X (imperative version "X"). The following converters USB - RS 232 were
tested and are satisfactory.
▪ Aten UC 232A (Is the one with the most updated drivers)
▪ Easysync US232B
▪ Easysync USB-COM
A 9 pins extension cable should be envisaged, in addition to the converter, because this device
cannot be installed directly on the DP2696. Podware software is available on request or can be
download on our Web site: www.tecnare.com.

4 The User Guide
This user manual gives a progressively more detailed description of the functions of the
TECNARE DP2696 Digital Loudspeaker Controller. A single page quick reference guide is
provided for those users who are experienced with this type of equipment and just need to know
how to ‘drive’ the front panel.
A detailed explanation of the front and rear panel controls and indicators is contained in the
next section. The final section describes each individual function or feature with annotated
images explaining its’ use. Where appropriate, the LCD is shown to further elaborate on the
units’ operation.
To complete the manual a reference section is included, describing the technical
performance of the device complete with graphs of filter responses and details of the Factory
Presets and their configuration.
4.1 Front panel
The front panel of the DP2696 provides access to all of the powerful features of the Digital
Loudspeaker Controller system.
Figure 1: Front panel schema
Input Signal Indicators
A set of three pairs of LEDs indicate signal present, +4dBu and input clip for each
channel. The signal present LEDs operate at approximately –40 dBu, giving a useful indication
of even relatively low input signal levels. The +4 dBu LEDs are intended to show nominal
operating level and can also be useful for setting system gain structure. Clip LEDs warn the
user of input overload and operate at +19 dBu.
Preset Store and Recall
These controls provide access to the 45 presets stored within the device. Pressing the
store button allows the user to name a preset and choose which memory location it will be held
in. Pressing store button again completes the process. The Recall function operates in a similar
way, pressing the recall button allows the user to select which preset they require, pressing the
button for a second time, then confirming, recalls the new DSP settings.
Note that presets cannot be stored or recalled when Secure mode is activated.

DP-2696 Operation Manual
Channel Select Buttons
The currently selected channel is displayed on the top left hand corner of the LCD.
Pressing the channel buttons scrolls through the available input and output channels and finally
through the utility functions and back to the default screen. If operating a stereo linked preset,
the channel name will indicate the channel pairing. For example ‘A+B’ means both input A and
B parameters. The name of the output will be shown briefly at the top of the display when
stepping onto an output.
Edit Select Buttons
The currently selected edit parameter page is displayed on the bottom left corner of the
LCD. Pressing the edit select buttons moves through the available parameters for the current
input or output.
Text Display
Preset, channel, parameter and status information is shown on the 2 x 24-character text
display. In most screens the currently selected channel is displayed on the upper line and the
edit parameter on the lower line. To simplify the display and enhance security, some
parameters or parameter pages are omitted when not relevant.
Parameter Knobs
Three velocity sensitive parameter knobs are used to adjust parameters shown on the
display. Up to three parameters at a time are displayed on the screen. The parameter name is
shown above the parameter value in each of the three screen sections. The parameter knobs
have a fixed association with the screen sections; the rightmost parameter knob adjusts the
rightmost parameter and so on.
Output Signal / Limiter Indication
Two LEDs are provided for each output channel. These show the signal level relative to
the limiter threshold. The yellow LED will light when the signal is 6dB below the threshold and
the red warning LED will light when the limiter threshold is reached.
Mute Buttons and Status LEDs
Each output has a mute button and associated mute status LED. Pressing the button
toggles the mute on and off.
Note that the mute buttons do not function when the Secure mode is activated.

4.2 Rear panel
The rear panel provides connections for two inputs and six outputs. An RS232 connector
allows connection to a remote computer running the “Podware” software. Optional PCC|Net cad
is available. PCC|Net must be plugged to the computer via USB, and the DP2696 linked to the
adapter with RJ45 cables(you can have several daisy-chained processors).
Figure 2: Rear panel schema
Power Inlet
The Tecnare DP2696 unit should be connected to a suitable mains electricity supply
using an earthed IEC C14 connection power lead. The processor has a switch mode power
supply that is capable of operating with a nominal mains voltage of 85V to 240V, 50/60Hz
without re-configuration.
NOTE: The DP2696 must be earthed to a suitable power earth; failure to do so may affect
performance and/or operation and will invalidate warranty and could be potentially hazardous.
Network Expansion Port
When fitted with a network option, the network connections will be here.
Communications Port Connector
Tecnare DP4896 processor may be controlled entirely from another controller, typically
a Personal Computer, running an application that is compliant with the ObCom standard.
Connection will normally be made to the controller via this serial port connector. This port is also
used for updating the firmware in the unit.
Note that the communications port is NOT disabled when the front panel is made secure using
the secure button.
DP Series | rev.
firm. 1.480 and above
16
Page 18
DP-2696 Operation Manual
Secure Button
A momentary button is fitted behind the rear panel, between the output XLRs and the
RS232 port. When activated, this will disable all the front panel controls so they cannot affect
the signal path, making the unit secure against tampering. When in secure mode, the indicators
still operate normally.
Note that the communications port is still active in secure mode.
Audio Output Connectors
The processed outputs are impedance balanced, and wired pin-1 ground, pin-2 hot and
pin-3 cold. An unbalanced input may be driven by connecting pin-3 ‘cold’ signal to the ground
connection of the unbalanced destination input. Note that output pin-1’s are ground lifted at
audio frequencies but connected to ground at RF for good EMC performance. The intention
being that the amplifiers the processor is driving should be responsible for the grounding of their
input cable shields.
Audio Input Connectors
All audio connections are fully balanced and wired pin-1 ground, pin-2 hot & pin-3 cold.
The two inputs have pin-1 connected directly to the chassis and feed the signal processing
chains. If an unbalanced source is used, a connection should be made between the pin-3 ‘cold’
signal and the ground connection of the unbalanced source.
5 Operation
Most of the functions and Systems setting in the Tecnare DP2696 are available via front
panel interface, navigating with the front panel buttons and knobs and viewed on the display.
The same functions are paralleled in the Podware control software. The user can choose to
control DP2696 from the front panel or remotely via Podware control software, as they are
interactive and communicate bi-directionally.
5.1 Starting up the unit
The unit will energise as soon as power is applied to the IEC inlet; there is no power
switch. During the start up process the firmware application model number and version numbers
are displayed and the outputs are muted until the unit has completed its internal checks. Once
the start-up routines are complete, the unit is ready to pass audio. The DSP signal path will be
restored to the same settings as when it was last powered down and the signal is gradually
ramped up to its correct level.
5.2 Selecting a Factory Preset
The DP4896 processors have a library of Factory Presets designed to suit a range of
applications. Factory Presets contain some parameters that are fixed and hidden from view; the
remainders of the DSP parameters are available for user manipulation. The number and type of
hidden parameters is dependant on the Factory Preset. To recall a Factory Preset for a
particular cabinet or system, press Recall and use the left hand parameter knob A to scroll
through the available Factory Preset locations (as indicated by a box symbol after the preset
number). Once the appropriate preset has been selected press recall again, at which point you
will be asked to confirm the action by pressing recall for a third time. This is to guard against
accidental recall of presets.
17 DP Series | rev.
firm. 1.480 and above
Page 19
Digital Loudspeaker Controller
Factory Presets are locked so they cannot be over-written. The user can, however,
store an edited version of a Factory Preset in any free preset location. Details of all the Factory
Presets including output designations can be found in Appendix A.
DP-2696 Operation Manual
5.3 Creating a Crossover
The Factory Presets are mono and stereo. These Base Presets are stored in locations 1
and 2 respectively. They can be used to develop settings for any loudspeaker. These presets
are locked but the user can name and store their own edited versions in any free preset
location.

Figure 3: Crossover Menu
Many of the processing elements in each input and output path have features that may
be controlled by the user, such as gain, frequency or limiter threshold. We call these adjustable
features parameters.
A parameter may be adjusted when it is displayed by turning one of the three-parameter
knobs. Each of the three-parameter knobs is associated with a zone on the display. Adjusting
the leftmost parameter knob will change the value of the parameter showing in the leftmost
zone of the display and so on. Turn a knob clockwise to increase the value of a parameter, or
anti-clockwise to decrease it. The knobs are velocity-sensitive so turning a knob rapidly will
cause the action to ‘accelerate’, so the value changes more rapidly.
5.4.1 Navigation
The DSP parameters are organised by channel. The currently selected channel is
shown in the top left hand corner of the display. You can navigate between the channels by
pressing the channel buttons. Pressing the channel buttons will scroll through the channels,
utilities and back to the default screen. When using a Preset that is stereo linked, the channel
selection will reflect this. For example ‘1&4’ indicates outputs 1 and 4. When navigating onto an
output channel, the usage of the output, as defined in the Preset, will be shown briefly at the top
of the screen.
Pressing the edit navigation buttons gives access to the various pages of parameters
available for each channel. The currently selected page is shown in the bottom left hand corner
of the display. This is omitted on some pages where the function is obvious. The screen shows
up to three (normally related) parameters for a given part of the processing functions on a given
channel.

The edit buttons allow you to scroll, in either direction, through the different processing
pages for a given Channel. When you go past the last page, you will be returned to the default
page. The channel buttons allow you to scroll, in either direction, through the input and output
channels, whilst trying to maintain the currently viewed processing block. If the channel you
scroll to does not have the currently viewed processing block, the next one will be shown
instead.
NB. When the unit powers-up, the settings will be the same as those when the unit was last
switched off.
5.5 Presets
The device contains a total of forty-five user and Factory Presets. The user cannot
overwrite the basic mono or basic stereo Preset programs.
5.5.1 Preset Recall
To select an existing preset, press the Recall Button so the indicator above it
illuminates. Turn parameter knob A until the required preset number is shown on the display.
Factory Presets are indicated by a box symbol appearing after the preset number. Press the
Recall Button again to activate the Preset. Pressing any other button will cancel the operation.
Users can develop their own Preset based on one of the Factory Presets stored within
the device. Once a Preset has been recalled, a user has complete freedom to adjust any or all
of the parameters. Factory Presets can be used as the basis for user Presets but they have
some parameters that are predefined as a function of the loudspeaker system. These
parameters are "hidden" from the user, as they should be constant regardless of application.

6.1 Stereo / Mono Formats
There is only one ‘standard’ layout of the processing blocks, but flexible routing and
control linking allows this layout to be adapted to a wide variety of applications.
There are two ‘Formats’, Mono or Stereo. With the Mono format, all outputs have unique
parameter settings, and all outputs are identical in terms of processing functions and routing
capability. This is the most flexible Format.
Stereo format pairs the inputs and outputs for stereo operation, the parameters of each
member of the pair being identical. The routing of inputs to outputs is fixed. This format is
intended for symmetrical stereo operation, eliminating the need to make identical parameter
adjustments for each channel.
The channel pairing is: Left and Right Inputs:
Outputs 1 (routed from L input) and 3 (routed from R input)
Outputs 2 (routed from L input) and 4 (routed from R input)
Outputs 3 (routed from L input) and 6 (routed from R input)

Knob A: Delay, adjustable in variable steps from 0 to 400ms
The delay parameter is adjustable in fine steps at low values; the adjustment becomes
progressively coarser as the value increases. The velocity sensitive Parameter Knobs therefore
provide accurate setting of driver offset delays (typically below 10ms) and rapid setting of longer
system alignment delays.

Knob A: Frequency, out (off), 20.0Hz to 25.6kHz in variable steps
Knob B: high pass filter type
System high pass filtering is provided for the input signal. This is the preferred location
for high pass filtering as it affects all outputs and can therefore improve inter-band phase
relationships. Filter type is selectable from Butterworth, Bessel, Linkwitz-Riley and Hardman.
Filter slopes of up to 4th order or 24dB / octave are provided. Not all filter types are available in
all slopes. For example 18dB / octave Linkwitz-Riley filters do not exist. The Hardman type filter
is always described by its’ order as the filter becomes progressively steeper rather than
following a linear slope so a dB/octave description is not accurate.
Parametric Equalisation
Eight sections of equalisation are provided, two shelving filters and six fully variable
parametric sections.

example 18dB / octave Linkwitz-Riley filters do not exist. The Hardman type filter is always
described by its’ order as the filter becomes progressively steeper rather than following a linear
slope so a dB/octave description is not accurate.

6.4 Utilities
Three utility functions are provided to adjust screen contrast, the display units used for
parametric equalisation bandwidth and switch between stereo and mono mode.
The device automatically adjusts for the variations in display contrast as the
temperature of the LCD changes. The screen contrast utility control sets the base contrast of
the screen and also allows optimization for a given viewing angle.
Parametric equalisation width parameters can be displayed in either ‘Q’ or bandwidth,
expressed in octaves.

Care should be taken when swapping between mono and stereo mode as the
parameter set for the left hand channels will be copied to the right hand side, overwriting those
settings. This is not reversible and could represent quite a significant and potentially damaging
change to the processing.
