KV2 Audio VHD3200, Operator'S Manual

GETTING STARTED

2.3 COOLING

The VHD 3200 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.

2.4 AC REQUIREMENTS

Two PowerCon cables are provided to connect the VHD 3200 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 VHD 3200 will be supplied pre set to the voltage used in your area.
The table below provides typical current draw figures for the VHD 3200. 

Remember 

that if you are connecting both AC cables for the VHD 3200 to the

same AC power source then you will need to have double the per channel
current available.
