Operating Voltage
The DPA-1 can be switched between 115V and 230V mains voltage.
In 115V mode the DPA-1 requires a mains voltage of 100V-120V at 50-60Hz.
In 230V mode the DPA-1 requires a mains voltage of 220V-240V at 50-60Hz.
The mains voltage setting for your DPA-1 can be changed on the rear selector.
Make sure the rear selector is in the correct setting and connect the power input
only to the appropiate AC source. The warranty will not cover any damage caused
by connecting to the wrong type of AC mains.
The DPA-1 has three power modes:
1. OFF
No circuitry is powered. Please note that some parts of the mains entry section still carry live mains.
2. STANDBY
The microprocessor is active.
3. ON
All circuits are active.
Unpacking the DPA-1
Carefully remove the unit and accessory kit from the carton, visually check for shipping damage.
Contact both the shipper and your Lyngdorf Audio representative immediately if the unit bears any sign
of damage from mishandeling. All Lyngdorf Audio equipment is carefully inspected before leaving our
factory.
Keep shipping carton and packing material for future use or in the unlikely event that
the unit needs servicing. If this unit is shipped without the original packing, damage
could occur and void the warranty.
Serial Number Registration
Please record the serial number of your DPA-1 here for future reference. The serial number is printed
on the label on the rear panel. You will need this serial number, should you ever require service for your
DPA-1.

Introduction
Congratulations on the purchase of your Lyngdorf Audio DPA-1 with RoomPerfect™.
Besides being a state-of-the-art pre-amplifier, it also enables you to take advantage of the most advanced
room correction system on the market. It is implemented in such a way that you will always achieve the
perfect result. No computer needed, no acoustic knowledge needed, no user input needed. We leave
nothing to chance in the fully automated calibration process.
However, for the advanced user there are plenty of challenges since the DPA is also a complete ‘Control
Centre’ that allows you to build advanced multi-way passive or active speaker systems. This is possible
due to the very powerful built-in DSP ‘engine’ which facilitates signal routing, creation of active cross-
overs, delay settings etc.
In fact we believe it to be the most versatile pre-amplifier on the market today, a true state-of-the-art
device that sets new standards for what’s sonically possible to achieve in a real life environment.

Front Panel
Controls
The buttons/controls on the front panel of the DPA-1 can all be operated either with direct presses or by
operating the corresponding keys on the supplied remote control. All the keys on the front panel (except
the Mains Switch) are duplicated onto the remote control as well.
1. Mains Switch
Powers the DPA-1 on/off.
2. Mute
Toggles Mute mode on/off.
Pressing the Mute button for 3 seconds will set the DPA-1 in stand-by mode.
3. Analog Input Selector
Changes to Analog input, or if already selected, cycles to the next Analog input.
In standby mode, press to turn On the DPA-1 with the last selected analog input.
4. Digital Input Selector
Changes to Digital input, or if already selected, cycles to the next Digital input.
In standby mode, press to turn On the DPA-1 with the last selected digital input.
5. Display
Display with all information on the menu system, status, active input selection and volume control.
6. Volume Wheel
Optical encoded volume control wheel.
7. Navigation Keys
In stand by mode, press Enter to turn On the DPA-1 with the last selected input.
In normal operation mode the Up/Down toggles between bypass and the available Focus and Global
filters. The Left/Right keys toggles between neutral and the available voicings.
In menu mode the keys are used for navigation in the menu system: Up/Down, Left/Right & Enter. Press-
ing and holding down the Up/Down, Right/Left keys, changes selected values fast.
