Boulder Amplifiers Integrated Amplifier 865 - Manual (Page 10)

POLARITY
Please note that the 865 Integrated Amplifier conforms to the
standard of Pin 2 as the positive or ”hot” pin for all analog balanced
inputs and outputs.
CONNECTING A BALANCED ANALOG SOURCE
To realize the greatest sonic potential of your 865 Integrated Amplifier,
use balanced connections whenever possible. Balanced cables reduce
interference from magnetic and RF sources to an absolute minimum.
Connect each line source to one of the four inputs provided. Later,
you will be able to program each input with the source’s name, so you
may want to make a list as you connect them.
