NOTE

Although the "cold" output terminals are nominally at 0V, they should not be joined

together;

otherwise cross

talk may be introduced.

Because the currents involved are very high, the speaker cables should conform to

the following minimum requirements, otherwise the losses will cause the cables to get

hot and audio power will be reduced:

A (

1500

) or 16A (

B2000

) -
