CAUTION
@® Be sure to supply the correct multi-amplified
signals to each driver. If this precaution is not
observed, the tweeter may be damaged by low
frequency overload, even though a protective
capacitor of: 30 UF: -is.-installed: in’ the -tweeter
section.
® Since the woofer is usually lower in efficiency and
level than other drivers, first set the low level
control at maximum as a reference level, and then
turn up the low mid-range, high mid-range and
high level controls in that order to equalize the
driver output. |
