6V6: Tube used in small American combo amps
delivers distortion even at a low volume level.
EL84: Tube often used in British combo amps
delivers a soft drive.
KT88: This tube is used in a variety of amps
designed for everything from jazz to metal
and produces little distortion even at raised

Connecting the Cabinet
n Cabinet Specications
Before connecting the cabinet, please check the
following two points.
lCabinet Power Rating
lCabinet Impedance
lCabinet Power Rating
SetthePowerOutputswitchontheamplier’srear
panel to the value that matches the power rating* of
the cabinet being connected to the amp.
* The power rating may be listed as “Power
Rating” or “Peak Power Rating” in the cabinet’s
specications.
lCabinet Impedance
SettheImpedanceSwitchontheamp’srearpanelto
match the impedance of the cabinet being connected
to the amp.
CAUTION
Using the wrong setting can damage the
speakers and the amp.
l Settings on the Yamaha THRC212 Cabinet
will
change power rating and impedance
requirements for the cabinet. Please read
the THRC212 Owner’s Manual carefully and
make the appropriate settings.
lWhen connecting multiple cabinets make
the proper settings after calculating the
overall system’s permissible input and total
impedance. Also, keep the impedance of
the connected devices within a range of 4Ω
to 16Ω.
nConnections and Settings
Connecttheampliertothecabinetusinga
commercially available speaker cable (mono phone
to mono phone).
CAUTION
l Always turn the amplier power OFF before
making connections or disconnecting the
devices. Not doing so can result in electric
shock.
l Never use an instrument (guitar) cable.
Using an instrument cable can damage the
speakers and the amp.
