The Reference subwoofer amplifiers are
single-channel amplifiers. There are two sets of
terminals to make it easy to connect multiple
woofers. Either set of (+/–) terminals may be
used when connecting woofers.
To the right are two application diagrams to help
plan your subwoofer system installation. Figures
3 and 4 show how to configure the Reference
subwoofer amplifiers (models 311a, 611a and
1211a).
NOTE: For simplicity, Figures 3 and 4 do not
show power, remote and input connections.
NOTE: Minimum speaker load is 2 ohms.
