Lab-Grade Audio Analyzer
Knowing where your frequency response problems exist is
half the battle of setting up a good sounding system. The
warble-tone signal generator and precision relative sound
level meter built into the Richter Scale provide an impartial
judge of the peaks, dips and speaker/room interactions. The
measurement microphone included with the Richter Scale is
lab grade and flat within 1 dB. The warble-tone generator
and sound level meter combine to create a very powerful
audio analysis tool.
Sharp Subsonic Filter for Speaker Protection
Now for a moment of realism...In spite of the great claims
made in the sales literature, a subwoofer can only play so low.
Trying to force a sub to run lower than is realistic will result
in wasted amplifier power, overheated speakers, distortion,
and worst of all, possible speaker failure. An 18dB per octave,
Tchebychev alignment highpass filter provides accurate low-
frequency bass protection for your speakers without cutting
into audible bass performance. You will have more clear,
tight bass than you thought possible from your stereo
system.
Audiophile-Quality Electronic Crossover
What good is it having a subwoofer to rattle the room if
you have a second-rate crossover driving it? Subwoofer
manufacturers are very good at designing speakers, but most
of them are fish out of water when it comes to creating an
electronic crossover. The Richter Scale Series Three includes
one of the best crossover topologies available: 24dB/octave,
Linkwitz-Riley alignment. The sharp roll-off of this design
makes certain the subwoofer only creates the low bass
frequencies for which it was intended. AudioControl makes
this crossover even more useful by providing plug-in pro-
gramming modules to set the crossover frequency. This
allows precision matching of the crossover and your
subwoofer. The result is solid bass you have to feel to believe.
Precision Bass Equalizer
Problems in the bass frequencies will have an affect
through the entire audio system. Excessive energy caused by
standing waves will mask fine details in the high end. The six
bands on the Richter Scale control this critical bass region of
22.5 Hz to 125 Hz in one-half octave steps. The controls are
stereo ganged to ensure consistent adjustment of the left and
right channels for more solid bass performance.
