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 crossovers, 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. Pressing and holding down the Up/Down, Right/Left keys, changes selected values fast.
