Both sets of speakers may be selected simul-
taneously as long as all speakers are norminally
rated at an impedance of 8 ohms or greater.
However, occasionally the actual impedance will
vary, depending upon the program material.
When the impedance drops too low, the HK
3370 will go into protect mode in order to pre-
vent damage to the equipment. If this should
occur frequently, be sure to select only one set of
speakers at a time until you are able to obtain
speakers with a higher nominal impedance.
