CONNECTING TO A BALANCED INPUT AMPLIFIER
With your 810 Preamplifier’s balanced output driving a balanced
input power amplifier, you can take sonic advantage of short speaker
cables and correspondingly longer input cables. With the 810’s
low output impedance, distances of more than 50 meters between
preamplifier and power amplifier are practical.
Connect each amplifier input to the main outputs labeled “MAIN
OUT.” If it is desired to use 2 or more amplifiers such as in bi-amping,
splitters will be required. If in doubt, consult your Boulder dealer.
