Boulder Amplifiers 1012 DAC Preamplifier - Manual (Page 15)

CONNECTING TO A BALANCED INPUT AMPLIFIER
With your 1012 DAC 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 1012’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.
