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.

4The 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
15 DP Series | rev. firm. 1.480 and above
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.

Digital Loudspeaker Controller DP-2696 Operation Manual
DP Series | rev. firm. 1.480 and above 16
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-2696 Operation Manual
17 DP Series | rev. firm. 1.480 and above
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.
5Operation
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 Presetscontain 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.

Digital Loudspeaker Controller DP-2696 Operation Manual
DP Series | rev. firm. 1.480 and above 18
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.
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.
5.4 Navigation and Viewing Parameters

a b c
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.

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 Presetsare 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.
