Optical Digital Inputs
B135³ DA: Digital inputs D3 and D4 accept
optical digital inputs from compatible source
components. On B135³ units with no DAC option
installed, these inputs are physically present but
internally disconnected and non-functional.
17.
Ground Screw
B135³ P: When connecting a turntable, also
connect a ground wire to the B135³ P when
available to eliminate hum due to a ground
loop.
18. A/C Power Input with Fuse
Compartment:
An IEC-320 C14 power inlet provides for
connection of an IEC-320 C13 equipped power
cord. Before connecting the power cord to the
amplifier, check that the voltage rating on the
data plate or ratings label conforms with your
locality. The B135³ is protected by an AC Mains
fuse specifically rated for the AC power in your
region. The fuse must be installed and intact
for the amplifier to power on and operate. Only
replace the fuse with one of identical value
listed on the Fuse Data Label.
Do not attempt removal or replacement of the
fuse when the amplifier is plugged into the
wall!
19.
Aux IR Input
When the front panel IR Sensor is blocked, you
may connect an auxiliary IR sensor to this input
to control the B135³ via IR remote control.
