Product description The black DVA MS12 Active Bass Reflex Flyable Subwoofer from dB Technologies is equipped with a single 12" woofer in a bass-reflex enclosure and a DIGIPRO G3 series class-D amplifier capable of delivering 700W PMS. It is equipped with a 12" woofer (3" voice coil). The digital pre-amplifier with Digital Signal Processor (DSP) manages the acoustic components, frequency response, limiter, and speaker alerts. The SMPS (Switched-Mode Power Supply) Power Supply Unit (PSU) thanks to its self-range technology ensures operation at supply voltages from 100 to 120V and from 220 to 240V. - Versatility
- This subwoofer delivers an incredible SPL considering its very compact dimensions, and it can be easily used both flown and ground-stacked. The smart design of the feet allows the user to avoid the dull removal of the flying brackets. It is possible to remove the feet in few seconds and screw them again upside-down. In this way any contact between the flying brackets and the ground is avoided, as only the rubber feet will touch it. A practical X-over out can be used to feed signal straight to the line-array modules, simplifying considerably the signal and power cabling.
- Digipro G3 Class-D Amplifier
- This subwoofer comes with the Digipro G3 digital amplifier. Distinguished by new features, lightweight design, and good efficiency, it pushes the system performance at its maximum. In order to let the speaker play flawlessly with both 110 and 220V power, a switched-mode power supply with auto-range circuit has been built inside this subwoofer.
- Download Telemetry from USB
- An integrated USB B-type port on the amplifier allows the user to access the complete telemetry of the sub, monitoring the status of the speaker, including total playing hours, temperatures, and performances reports. It is also possible to download a file log as a status report, as well as upgrade the firmware using the same USB port.
