RCA Surround Output / Subwoofer Connection
The Reference 50 Series2 supplies 7.1 RCA coaxial surround outputs. These surround outputs can be used
to connect an external amplifier or the subwoofer to the preamplifier. To connect seven audio channels,
connect seven coaxial audio cables between the surround outputs and the amplifier inputs. Be sure to match
the appropriate preamp output to the speakers location in the room, i.e. connect the center channel output to
the center speaker amplifier channel. If a 5 channel audio system is desired, do not connect the surround
back audio channels. If a 6 channel audio system is desired, connect the 6
th
channel to the surround back
left channel. See page 25 for speakers setup.
If a subwoofer is used, The Reference 50 Series2 has two subwoofer outputs, one balanced (XLR)
Subwoofer out and one coaxial (RCA) Subwoofer out, either output can be used. Connect the subwoofer
cable from the subwoofer output to the subwoofer. The diagram below illustrates seven channels plus the
subwoofer connected using the coaxial RCA outputs.
