II the combined impedance is less than 4 ohms.
the protection CITCUII may operate and mute the
power-output stage The combined impedance
can be calculated as shown below

AXB
A+B

COMBINED IMPEDANCE : (OHMS). where

A: Nominal impedance ol the A speakers.

B: Nominal impedance at the B speakers

So. lor 8-ohm speakers, the combined impedance
would be (8* 8)/l8+8l or 4 ohms. which is a
satislactory value It in doubt. please consult youi
audio dealer lor additional information
