OUR PART # RACKDP50
The Turbosound RACKDP-50 is a four channel power amplifier integrating lightweight power supplies, high power sonically transparent Class-D amplifiers, full system monitoring (including 'end of line') and a fully featured USB or network controlled 24-bit/96 kHz DSP processing platform provided onboard as standard. The RACKDP-50 contains four channels of 1,250 W class-D amplification, providing significant benefits in efficiency and power density over conventional amplifier types.
The design has produced a short signal path which directly results in clean, fast amplification that is so efficient that even though capable of a total power output of 5,000 W, the variable-speed fans only run at high speed under extreme conditions. The advantages of switching technology have been carried through to the extremely efficient lightweight power supply evolving in harmony with the amplifier section and therefore achieves an optimum match between the two. Intelligent detection of the mains supply voltage makes the unit suitable for global operation without requiring any reconfiguration. Each pair of channels contains a complete 96 kHz digital loudspeaker management and control subsystem, containing an extremely powerful state-of-the-art floating point SHARC based DSP engine.
A simple PC connection allows customers to manipulate DSP parameters to optimize the performance and develop user settings, which are stored in the RACKDP-50 so a PC is not necessary for operation, for particular applications. The RACKDP-50 can also recall different settings (voices) by the means of rear panel auxillary port, useful in voice evacuation applications where it may be required to mute the current source of audio, switch to an alternate input carrying an evacuation message and broadcast it with different level and EQ settings.
The RACKDP-50 is networkable as standard, and the Turbosound TurboDrive PC application provides real-time control and monitoring functions for either single units or whole networks of products, PC connection being made either directly via USB or BVNet. Networked RACKDP-50s allow system installers to more easily optimize the performance of individual speakers in a space, solving a number of problems that cannot be addressed adequately with the traditional approach of one centralized system controller.
Networked amplifiers and TurboDrive also allow all the important system parameters, including load impedance, to be monitored and displayed. Sophisticated microprocessor controlled amplifier protection systems continuously monitor all aspects of performance and under extreme or abusive conditions the RACKDP-50 will progressively decrease the audio level while endeavoring to find a stable operating level. Even without a PC connection, the RACKDP-50 continuously records logs against time for the temperature readings, and the state of amplifier protection for up to three days into the past. These may be easily viewed at any time and their data can even be exported to a spreadsheet for further analysis.
