Turbosound RackDP-50 Power Amplifier

The RACKDP-50 is a 4-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 96kHz DSP processing platform provided onboard as standard.

The RACKDP-50 contains four 1250W channels of 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 5000W, 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 is suitable for global operation without requiring any reconfiguration. Each pair of channels contains a complete 96kHz 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 optimise the performance and develop user settings – 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 auxiliary 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.

All RACKDP-50 models are networkable as standard; and Turbosound’s TurboDrive PC application provides real-time control and monitoring functions for either single units or whole networks of products. A PC connects to the RACKDP-50 either directly via USB or BvNet. Networked RACKDP-50s allow system installers to more easily optimise the performance of individual speakers in a space, solving a number of problems that cannot be addressed adequately with the traditional approach of one centralised system controller. Networked RACKDP-50s and TurboDrive also allow all the important system parameters, including load impedance, to be monitored and displayed. Sophisticated micro-processor 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 endeavouring 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 3 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.
