4. Equalizer Switch - This allows simple before and
after comparisons of the system equalization. When pressed
in, this button activates the half-octave equalizer circuitry.
5. One-half Octave Bass Equalizer - This six band
bass equalizer gives you incredible control over the critical
low frequency region of your room and speakers. The sliders
are stereo-ganged so you can accurately adjust both channels
at the same time.
6. Subsonic (Highpass) Filter Switch - Press this
button to get rid of power robbing, distortion inducing
infrasonics. This sharp 18dB per octave filter cuts off bass
frequencies below 18Hz to protect your system against these
audio demons. The Richter Scale utilizes a sophisticated, 3-
pole Tchebychev alignment design does away with subsonic
interference without any audible side effects. Almost every
stereo will benefit from this filter, so don’t be afraid to leave
it on.
7. Rumble Reduction Filter Switch - This button is
dedicated to the good old days of analog vinyl sound and the
turntable. One press and say “good-bye” to turntable rumble
and acoustic feedback. It even reduces the thump you hear if
you lower the cartridge too quickly onto a record.
8. External Processor Loop Switch - Since the
equalizer section of the Richter Scale is usually connected
into the tape monitor loop of your preamp, we thought it
was only fair to give you one back. This button works the
same as the tape monitor on your receiver and switches the
Richter Scale input between the Main Input and the External
Processor Input.
9. Crossover Low Output Mute Switch - A quick
way to shut off your subwoofer and remind you why you
have one in the first place. This button mutes the low pass
output of the electronic crossover built into the Richter
Scale.
10. Crossover Low Output Level Adjustment -
A variable gain control to match the subwoofer volume to
the main speakers. This control is recessed because it should
only need to be set when the system is initially analyzed and
set up.
11. Power switch - Need we say more???
