VHD2000 · Getting started
Unpacking
Unpack the VHD2000 and check to see if there is any damage to it. If you find any damage notify your supplier immediately.
Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and
all packing materials for the carrier's inspection.
Should you ever need to ship the unit, only use the original factory packaging. If the shipping carton is unavailable, contact
your supplier to obtain a replacement.
The VHD2000 carton should contain:
• VHD2000 amplifier control unit
• User's Guide
• PowerCon detachable power cable
Rack Mounting
VHD 2000's 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 VHD2000 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 VHD2000.
AC Requirements
A PowerCon cable is provided to connect the VHD2000 to a suitable AC power supply.
The PowerCon is a connector without breaking capacity, i.e. the PowerCon should not be connected or disconnected
under load or while it is live. Always isolate your AC supply before disconnecting the PowerCon connector.
Your VHD2000 will be supplied pre set to the voltage used in your area. The table below provides typical current draw figures
for the VHD2000.
Cooling
The VHD2000 has a comprehensive cooling system featuring chassis-sealed PCB board mounting and shock mounted, speed
controlled fans. This means that the cooling system never drives air across PCB boards, connectors or components ensuring
prolonged electronic component lifespan and minimizing maintenance cycles.
Air is drawn into the front of the amplifier by the two fans on the rear panel, this passes over the cooling fins of the heat sinks
and exhausts through the rear. If the heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the load.
It is important to have an adequate air supply at the front of the amplifier, and enough space around the rear of the amplifier
to allow the cooling air to escape. If the unit is rack mounted, do not use doors or covers on the rear of the rack; the exhaust
air must flow without restriction. If you are using racks with closed backs, use fans on the rear rack panel to ensure an ample
air supply.
