Connecting to Loudspeakers
Connection to loudspeakers is accomplished by
attaching high quality speaker cable to the Output
Binding Posts (see “Rear Panel” on page 8) per
the following instructions.
The
RED
binding posts are connected to the
positive channel output. Both RED posts are
internally connected together. Connect both
or either RED post to the (+) terminal on the
loudspeaker.
The
BLUE
binding post is connected to the negative
(-) output. Both BLUE posts are internally connected
together. Connect both or either BLUE post to the (-)
terminal on the loudspeaker.
Never connect either binding post to a ground! The
amplifier is balanced.
The output binding posts provide three different
interconnect options. Combinations may be used
when bi-wiring. Cables should be kept as short
as practical and should never be terminated with
connectors that may become confused for AC
power connectors. Cables should be dressed away
from input and power cables.
Banana plugs offer a quick disconnect option.
Before inserting a banana plug into the binding
post, be sure to tighten the post nut to avoid rattling
and to provide full insertion of the banana plug.
Gold plated locking banana
plugs are available from
Bryston.
Spade lugs provide high contact
area and secure fastening.
Lugs should be gold plated. Post diameter is 5/16”
(8mm), lug width 5/8” (16 mm). Gold plated spade
lugs are available from Bryston.
Stripped bare wire up to 3 gauge can be inserted
through the hole in the binding post and held
in place by tightening the post knob. Additional
tightening pressure can be achieved using a coin
in the slots of the knob. Do not over tighten or the
binding post may become damaged. Note that
copper wire is malleable and may require further
tightening after the initial installation.
To prevent the risk of equipment damage or
personal harm, use only Class 2 rated loudspeaker
wire properly terminated and connected securely to
the binding posts.
Connecting Audio Inputs
The Bryston Cubed amplifier can receive analog
audio from any preamp or surround processor with
volume controlled line-level outputs. Balanced XLR
and TRS as well as singled ended RCA inputs are
both available and can be selected using the Input
Select switch on the rear panel of the amplifier.
