10. Loudspeaker Output Binding Posts
The RED binding post is connected to the
positive amplifier output. Connect to this post
the (+) terminal on the loudspeaker..
The BLACK binding post is connected to the
negative (-) output. Connect to this post the (-)
terminal on the loudspeaker.
Never connect either binding post to an
electrical ground!
The output binding posts provide three different
interconnect options: banana plugs, spade lugs,
and bare wire. 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.
11. Connected / Separate
These switches (one per channel) internally
connect or disconnect the preamplifier and
amplifier functions. When in the Connected
position, the B135³ functions normally (volume
controls loudspeaker level). When in the
Separate position, the amplifier section receives
audio via the Power Amp In RCA jacks. The Pre
Amp Out jacks are always live and their output
level is controlled by the volume knob.
12. Record Output
Fixed level analog output is identical to current
analog source selected useful for connecting a
tape recorder, CD recorder. or other recording
device.
13. Analog Inputs
Each input pair corresponds with a button on
the front panel. Connect the left/right analog
outputs of each source component to a left/
right analog pair of jacks.
B135³ DA:
AUX 2 becomes two separate digital
inputs (D1 and D2)
B135³ P:
AUX 1 feeds the internal MM phono
stage. Only connect a turntable to these inputs!
Not for regular line level analog.
14. RS232 Connector
Control the B135³ using
RS232 based home
automation systems by
connecting this input to
the automation system.
