Cabinet 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.
l
Cabinet 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.
l When 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.

Connections and Settings
Connecttheampliertothecabinetusinga
commercially available speaker cable (mono phone
