Unlike other attempts at bass synthesis, the 120As patented
subharmonic synthesis process produces smooth, musical low frequencies
that dont interfere with mid- or high-band information
even at maximum levels. The result is unmatched low-end
punch at levels that wont destroy your system. In fact, the 120A
is optimized to allow audio professionals to get the most out of
their high-performance, low frequency speaker systems, and
includes both a subwoofer output (with its own level control) and
main outputs that can be configured as either full-range (including
synthesis) or high frequency-only.
