Selecting DHE Mode

Using digital signal processing technology, DHE
(Digital Harmonics Enhancer) operates on
harmonic components which determine tone and
coloration of the musical instruments. The
process operates independently on individual
frequency bands, so each instrument or vocal will
be distinct. Play back clarity is enhanced to
compensate for road noises which would normally
detract from the listener's enjoyment.
