Balanced Audio Technology VK-220 Owner's Manual - page 4
Physical Placement
It is recommended that you provide for at least 6" of free space around the unit for proper
ventilation.
Mount the unit on a hard surface with proper ventilation underneath.
Do not stack the VK-220 power amplifier on top of other units, nor vice versa.
IMPORTANT NOTES
:
To assure reliable operation always turn the VK-220 OFF while making or changing
input or speaker connections. No connections should be made while the
amplifier is ON.
If the VK-220 was turned OFF for any reason, wait at least 30 seconds before
turning it back ON.
Power Connection
Due to the VK-220 amplifier’ high power rating, it is important to assure the good quality
power line connection. If separate circuit outlets are used for the preamplifier and power
amplifier, it is recommended that both circuits be connected to the same phase of the power
line. Otherwise, a high level of hum can be present.
Input Connections
Best results will be obtained when connecting the VK-220 to a balanced preamplifier.
However, the VK-220 is designed to accept either balanced or single-ended inputs.
Balanced Components
Use balanced XLR interconnects to connect the VK-220 to a balanced preamplifier. Input
connectors are clearly marked on the back panel.
Note: The VK-220 input XLR connectors are wired as follows:
Pin 1:
common/shield
Pin 2:
positive
Pin 3:
negative
