INSTALLATION
SounDigital
POWER amplifiers feature high-precision
adjustable crossovers that increase audio quality and
speaker performance.The choice of frequency depends
on the system design, if you have any questions about
which crossover frequency to use, refer. If you have any
questions about which frequency cut filter to use, refer to
the speaker technical manual, to which the amplifier will
be connected.

Using Bass Boost
The Amplifier Bass Boost setting enables the user to boost
the sound intensity at low frequencies of the sound system,
where boost intensity can be adjusted, as well as the
frequency of the region to be boosted, as indicated in the
chart . This is a semi-parametric equalizer type circuit with
"Q" value for the fixed filter, with an intensity boost
adjustment from 0 to +12dB (16 times), and a central
frequency adjustment of the filter between 35 and 55Hz,
making it versatile for several types of sound systems.
