* In an
effort to maintain the be
st quality and functioning product on the market co
ntinuous changes such
as the following are made as a "Running
Change" improvent. In some model amplifiers the
"HIGH LEVEL" input was replaced wi
th an "INPUT SENSITI
VITY MULTIPLIER". This two position swit
ch
allows the amplifier to make full po
wer at a wider range of voltage input with
out the use of a li
ne driver or sacrifice of sound quality. The following chart
explains the variations entitled to such changes.
