SPECIAL FEATURES
Surround Circuit: Jim Fosgate integrated his surround circuitry
design, part of his US patent 5,307,415 “Panorama Control” filed in
April 1994 in his Signature headphone amplifier. This circuit applies
an out of phase cross blend to create a sense of depth and space
and moves the dimensional soundstage outside of your head. The
control has Min, Max, and Off positions. In the center off position, the
surround circuit is bypassed so the signal is unaffected and provides
normal stereo.
Bass Equalizer: The bass boost equalizer circuit
is designed to give the headphone listener defined, low
frequency bass impact without bass boom. There are
three positions on the bass control, Min, Max, and Off.
When the control is in the center Off position, the bass
boost is bypassed. This circuit has been used in
different forms in many products including Rockford
Fosgate Car amplifiers. Jim Fosgate received US
patent number 3,883,832 for this circuit in 1975. It is
called a "SINGLE ELEMENT CONTROLLED TWIN T
FILTER" and has a much steeper curve then a typical
bass or loudness control. It changes frequency and amplitude (Boost)
with a single control.
When the control is set in the Min position, the maximum boost is
applied at a lower frequency.
When the control is set in the Max position, the maximum boost is
applied at a higher frequency.
Using the special features: Depending on the type of
headphones you prefer, your listening habits, and the musical selection you
chose, experiment with these special features for the greatest listening
pleasure. Both features may be used in conjunction. You may find that
using the surround circuit for classical recordings will better recreate the
ambience of the concert hall and the bass eq will .
