Overview:

Thanks to the integrated Quick-Release-Pins, both DRK-10 and DRK-20 frames can be easily mounted to set up a ground stacked system.

Features:

• Active Subwoofer 2000 Watt RMS
• Made of sturdy birch multiplex covered in robust black textured lacquer
• The subwoofer housing is fronted with a rugged speaker grille.
• The enclosure is easy to tote with its comfortable carrying handles.

1) "MAINS FUSE" FUSE CARRIER - Mains fuse housing.

2) “FULL RANGE MAINS INPUT" POWER SOCKET - For connecting the power cable provided. The connector used for mains connection is a POWER CON® (blue)

3) COOLING GRILLE - These grilles permit cooling the amplifier during operation.Do not block accesses and clean the grilles whenever necessary to ensure correct air circulation.

4) " BALANCED MAIN INPUT” INPUT CONNECTOR -Balanced input at line level (0 dBu). It is able to accept “XLR” sockets.

5) "LINK” OUTPUT CONNECTOR - The “XLR” connector connected in parallel with input (4) can be used to send the input audio signal to another amplified speaker.

6) ”BALANCED X-OVER OUTPUT” OUTPUT CONNECTOR - Internal crossover balanced output. The signal from this output can be sent to any other amplified speaker. The crossover frequency can be selected by means of the “SUB X-OVER” switch(7).

7) “SUB X-OVER” SWITCH - This switch permits selection of crossover frequency between the sub woofer and the speakers connected to the ”BALANCED X-OVER OUTPUT” connector.The crossing frequency is selected to 90Hz or 120Hz with a slope of 24dB/oct.The frequency choice depends to the sound reproduction desire.

8) “SUB PHASE ” SWITCH - This switch permits 180° rotation of the audio signal reproduced by subwoofer. Rotation makes for easier optimization of low-frequency reproduction even in the most difficult installation situations. After completing installation, reproduce a piece of music and adjust the switch to obtain the best low-frequency sound.

9) “ON” INDICATOR LIGHT - The “ON” indicator light comes on green to indicate the amplifier is switched on and it is working properly.

10) “SGN” INDICATOR LIGHT - This indicator comes on green to indicate the presence of the audio signal (at a level of -20dB).

11) “LIM” INDICATOR LIGHT  - This indicator comes on red to indicate that the internal limiter circuit has tripped. This prevents amplifier distortion and protects the speakers against overloads. It is lights for a few seconds during the switching on.

12) “SUB WOOFER LEVEL” INPUT SENSITIVITY CONTROL - This control regulates the sensitivity of the signal at amplifier input. This control does not affect the “LINK” and “BALANCED X-OVER OUTPUT” output levels

13) DIGITAL DELAY “SDD - SUBWOOFER DIGITAL DELAY” OPTION - The DVA loudspeaker can be equipped with a delay module (SDD - SUBWOOFER DIGITAL DELAY) that allows to delay the sound signal reproduced by the subwoofer. S20dpThis circuit allows sound-alignment between line array and sub by balancing the various positions. The circuit also includes a balanced “XLR” output that sends the delayed audio signal to other subwoofers. By using a single delay module it is possible to delay several subwoofers at the same time.

This module can also be used to create cardioid configuration systems. The cardioid configuration provides a remarkable attenuation of the low frequencies radiated by the rear side of the subs, without changing the direct radiated signal on the front side. This configuration needs at least 3 subwoofers (two with front radiation and one with rear radiation equipped with SDD module).
