apparatus.
•
Only use attachments/accessories specified by the manufacturer
• Servicing is required when the apparatus has been damaged in
any way, such as the power supply cable or plug is damaged,
liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
1.1 Regulatory Compliance
This product complies with both the EMC Directive (89/336/EEC)
and the Low Voltage Directive (73/23/EEC) as issued by the Commission of the European Union. Compliance with these directives
imply conformity with the following European standards:
• EN60065 Product safety
• EN55103-1 Electromagnetic Interference (Emission)
• EN55103-2 Electromagnetic Susceptibility (Immunity)
This product is intended for operation in the E2 (commercial & light
industrial) and E3 (urban outdoors) Electromagnetic Environments.
1.2 Special thanks
Thank you for choosing a loudspeaker management system
X-Treme Digital Processor (XTDP) for your applications. Please
spare a little time to study the contents of this manual, so that you
obtain the best possible performance from this unit. All X-Treme
products are carefully engineered for world-class performance and
reliability. If you would like further information about this or any other X-Treme product, please contact us. We will be pleased to help
you in any way we can.
1.3 Unpacking the X-Treme XTDP controllers
After unpacking the unit please check carefully for damage. If damage is found, please notify the carrier concerned at once. You, the
consignee, must instigate any claim. Please retain all packaging in
case of future re-shipment.
2. Introduction and Key Features
2.1 Introduction
The loudspeaker management systems X-Treme XTDP24 and
XTDP26 represent the current state-of-the-art. Taking advantages
of the latest advances in analogue to digital conversion and digital
signal processing technologies the units achieve performance levels that have only recently been made possible.

2.2 Key Features
• Minimal signal path design
• Sonically superb ADC / DAC combination thanks to a carefully
matched pairing of the best devices from Burr Brown and Wolfson
• Newly released family of Analog Devices SHARC DSP
• Extended bandwidth; 96kHz sampling frequency provides for a
nominally flat response to 40kHz.
• Parameter knob and LCD provide rapid, user-friendly control
3. Front Panel
3.1 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.
3.2 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 the
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.
3.3 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.
3.4 Output Signal / Limiter Indication
Two LEDs are provided for each output channel. These show the
signal level related to the limiter threshold. The yellow LED will light
up when the signal is 6 dB below the threshold, while the red warning LED will light up when the limiter threshold is reached.
3.6 Secure Button
A momentary button is fitted behind the rear panel, between the
output XLR 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.
3.7 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 safety, some
parameters or parameter pages are omitted when not relevant.
3.8 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.
3.9 Edit Parameters 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.
3.5 Mute Buttons and Status LEDs
Each output has a Mute button and associated mute status LED.
Pressing the button turns the mute on and off.
Note that the mute buttons do not function when the Secure mode
is activated.

4.1 Power Inlet
The X-Treme XTDP units should be connected to a suitable mains
electricity supply using the cable supplied. 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.
4.2 XT-NET Port
This is the port - with RJ45 connection - for the remote controlling
of a network with many other devices (XT-NET); everything is done
from only one external PC using the software Network Contoller.
4.3 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 supply 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.
4.4 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.
4.5 Expansion Port and Serial Comms Port
X-Treme XTDP controllers may be controlled - one by one - entirely
from another device, typically a Personal Computer, running an application that is compliant with the ObCom standard: the Network
Controller. Connection will normally be made to the controller via
this serial port connector (RS232). 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.
