Balanced Audio VK-255SE - 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-255SE power amplifier on top of other units, nor vice versa.
IMPORTANT NOTES:
To assure reliable operation always turn the VK-255SE OFF while making or
changing input or speaker connections. No connections should be made while
the amplifier is ON.
If the VK-255SE was turned OFF for any reason, wait at least 30 seconds before
turning it back ON.
Power Connection
Due to the VK-255SE 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-255SE to a balanced preamplifier.
However, the VK-255SE is designed to accept either balanced or single-ended inputs.
Monoblock Connection: On the VK-255SEM Power Monoblock either left or right input
can be used for input connection – either one will produce identical results.
