INTRODUCTION, WARRANTY
Thank you for purchasing this KV2 Audio VHD3200 subwoofer amplier. This manual contains
important information on operating this unit correctly and safely. Please take some time and read
this manual to familiarise yourself with the advanced features of this unit.
The VHD3200 is a rack mounted subwoofer amplier. The unit contains two separate 1600 watt
ampliers with individual power supplies, signal paths and inputs and outputs within a single four
rack space chassis. The unit can be used in bridged mode to provide full power for one channel
mode. The unit acts as a slave for the VHD2000, which provides audio and control signal. It can
also be used with the EPAK2500/R when used in combination with KV2 Audio ES systems and
power the associated ES subwoofer systems.
Although this unit is simple to operate improper use can be dangerous. This is a very highpowered device that can put out high voltages and sizable currents. Always use safe operating
techniques with the VHD3200.
FOR YOUR SAFETY , READ THE IMPORTANT PRECAUTIONS SECTION AS WELL AS THE INPUT,
OUTPUT AND POWER CONNECTION SECTIONS OF THIS MANUAL.
WARRANTY
Your VHD3200 is covered against defects in material and workmanship. Refer to your supplier for
more details.
SERVICE
In the unlikely event that your VHD3200 develops a problem, it must be returned to an authorized
distributor , service centre or shipped directly to our factory. Because of the complexity of the
design and the risk of electrical shock, all repairs must be attempted only by qualied technical
personnel.
If the unit needs to be shipped back to the factory, it must be sent in its original carton. If improperly packed, the unit may be damaged. To obtain service, contact your nearest KV2 Audio Service
Centre, Distributor or Dealer .
GETTING STARTED
2.1 UNPACKING

2.2 RACK MOUNTING
VHD3200’s will mount in standard 19" rack systems. Integral rear mounting rack ears are also
provided for additional support, do not rely on xing and mounting the VHD3200 using just the
front panel as support. Use eight screws and washers to mount the amplier 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 VHD3200.

GETTING STARTED
2.3 COOLING
The VHD3200 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 amplier by the two fans on the rear panel, this passes over the
cooling ns 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 amplier, and enough space
around the rear of the amplier 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 ow 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 VHD3200 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 VHD3200 will be supplied pre set to the voltage used in your area. The table below
provides typical current draw gures for the VHD3200.

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.

1) AC Mains Switch
The VHD 3200 has combination AC Mains switch/circuit breakers on the front panel. If either of
the switches shuts o during normal use, push it back to the ON position once. If it will not stay on
you should take the unit to qualied service personnel tohave it serviced.
2) Power On / Thermal
These are dual colour LED’s. When green they indicate that the Power Switch is On and that
channel of the amplier is powered up. When red they indicate that that channel has overheated
and shut down. The unit will Auto Reset after it cools down to a safe operating temperature.
3) Signal Present
These green LED’s indicate when signal is present at the Input to that particular channel of the
amplier.
4) Limiter
These red LED’s indicate when the audio limiter has been activated for that particular channel of
the amplier.

1) Main Input A/B
These are the input connectors for channels A & B with associated 'Through Output' connectors for
sending signal to other devices.
2) Bridge Mode Switch
When running VHD3200 in bridge mode (bridge switch pressed), Input A serves as a bridge mode input,
bridge output (6) serves as speaker output. Input B provides phase reversed Input A signal.
3) PowerCon Power Connectors
One for each channel of the VHD3200 both must be connected to operate both channels of the
VHD3200. They accept standard PowerCon terminated AC Mains cables.
4) Fans
The cooling fans operate continuously while the VHD3200 is on. An internal temperature sensor
increases the speed of the fans during high temperature conditions. Air enters through the front grille
and exits through the rear. Be sure to allow adequate air ow to the front of the rack in which the
VHD3200 is mounted.
5) EP4 Connectors
One for each channel of the VHD3200. They accept standard EP4 terminated loudspeaker cables.
6) Bridge Mode EP4 Connector
Output channel of the VHD3200 when running in bridge mode. Accepts standard EP4 terminated
loudspeaker cables. Do not connect other speakers to speakers output A and output B in bridge mode.
OPERATION
The VHD3200 is designed to be used either with the VHD2000 or the EPAK2500/R controller
ampliers and to power only certain combinations of KV2 Audio Subwoofers. Because of its
unique design it cannot be used as a standard power amplier to power any other loudspeakers
without the possibility of damage occurring. The various VHD2000 combinations are shown in the
following table:
