Patented
The Source Units utilize a refined high performance tuner for provid-
ing unmatched tuning range. The tuner uses a patented Digital
Automatic Alignment (a mini pre-programmed computer) to pre-
cisely target and "tune in" FM radio stations. The aftermarket standard
is done by mechanical alignment which relies on not-so-precise
tunable inductors to "get within the ballpark" of a radio station. The
tuner is also refined with Dual FM Conversion and Dual AM Up-
Convert schemes to create a tuner that is capable of receiving radio
signals better.
THE RESULT: Absolutely the "world's best tuner"
MIR Circuit
The MIR (Multipath Interference Rejection) Circuit improves audio
performance under difficult reception conditions. The tuner slowly
tapers from stereo to monaural when excessive static is produced due
to poor radio reception in fringe areas. This feature is virtually
undetectable by the listener due to its smooth transition from monau-
ral back to stereo. The MIR circuit improves audio quality by reducing
multipath effects in both weak and strong signal conditions.
THE RESULT: Improves audio performance when radio reception is poor

REAMP
High Output Voltage/
Low Source Impedance
A high preamp output voltage allows a cleaner signal to be driven to
the amplifier. A low source impedance (50 ) enables the preamp to
drive multiple amplifiers without signal loss. It is not enough to have
only a high voltage output; to take full advantage of the extra voltage,
a low source impedance is essential. These two features are an
important combination for a preamp that truly delivers a Punch!
THE RESULT: Resists noise and enables multiple amplifiers to be
driven without signal loss
