VHD5 Power Unit · Front Panel

VHD5 Power Unit
The VHD5 Power Unit allows the VHD5000 series amplifiers to be used as an easy plug and play, rack mounted system. The unit provides power for a single VHD5000, plus one VHD5000S and three additional adjacent devices, for example the VHD5100 (using 2 of the 3 additional outputs) from just one 3 phase 230V/16A power outlet. The VHD5 Power Unit also provides interconnection of all signal and data cables from the rear of the individual amplifiers to the front of the rack system. The Unit provides easy management of the system speaker cables between the amplifiers and the VHD5 series speakers, using an LK multi-pin connector. Many of the connections on the front of the unit are mirrored from those on the rear of the amplifiers, making the connectivity quick, easy and intuitive.
Front Panel

VHD5 Power Unit · Front Panel

1) 3×230 VAC/16A
This is the mains 3 phase 230 VAC/ 16 A mains power input accepting a standard IEC60309 230V/16A plug. nOTE – The VHD5000 amplifiers should be powered off when plugging or unplugging the 3 phase socket. When the remote control power on/off is required, use the amplifier’s standby mode or a suitable 3 phase contactor.
2) L1,L2,L3 indicators
These indicators light up green when L1, L2, L3 are present.
3) OUTPUT FILL
This output socket serves as an interconnection between the VHD5100 amplifier’s AP6 Fill speaker output and the front panel power unit.
4) VHD5 BREAKOUT
Using an LK multipin connector, this is the main VHD5 system speakers output connector and contains a combined output for 1xVHD5.0, 3xVHD8.10, 1xVHD5.1 and control for the VHD5 Flybar.
5) FLYBAR COnTROL
The Flybar control is two channels, one for complete system Tilt, the second for Pan (or Flybar rotation). The indicator shows which remote control function of the flybar is selected, altered by switching the button below. Using the Pan selection, the flybar rotates left when the left button is pressed and right when the right button is pressed. In the Tilt mode the left button offers tilt “up” or straight and the the right button will tilt the system down. The Flybar motor movement is indicated using the red tilt light. When the motor reaches its limit position, the motor automatically stops and the red light goes out. When the tilt light flashes, the motor output is overloaded and an auto reset cutoff is activated. This indicator may also flash during startup.
6) Ethernet and signal – XLR inputs and outputs interconnections
The VHD5 Power Unit serves as the interconnection of signal, power and data cables from the back to the front when using VHD5000 series amplifiers rack mounted. Each connector is labeled on the front to mirror the inputs and outputs on the rear which are then connected permanently into the VHD5000 series amplifiers, making the rack interconnection intuitive and speeding up the overall set up process.

Rack Mounting

where children may be present.

VHD5000 will mount in standard 19″ rack systems. Integral rear mounting rack ears are also provided for additional support, do not rely on fixing and mounting the amplifiers using just the front panel as support. Use eight screws and washers to mount the amplifier to the equipment rack rails (four for the front and four for the rear). We recommend using a shock mounted rack for touring use to prolong the life of your VHD5000 amplifiers.
