Boulder Amplifiers Integrated Amplifier 865 - Manual (Page 14)

1-8
POLARITY
Please note that the 865 Integrated Amplifier conforms to the
standard of Pin 2 as the high or ”hot” for the balanced inputs.
The polarity of the 865 is such that a positive-going transition at
Pin 2 will produce a positive-going transition at the ”+” loudspeaker
terminal.
CONNECTING YOUR LOUDSPEAKERS
Do not use any wrenches on the loudspeaker binding posts. Tighten
these connectors only by hand.
WARNING: The 865 is a high powered amplifier. When driven, there
is a high voltage potential at the terminals.
Connections should only be made with the AC mains disconnected.
Select spade terminals which accept 6 mm or .250 inch diameter
binding posts.
There is no provision for the use of banana plugs. These plugs have
been proven to come loose over time which increases contact resistance
and distortion. For the same reasons we also do NOT recommend the
use of banana plugs at the loudspeaker end.
