SAE Mark
Nine Preamplifier Equalizer
The SAE Mark
IX offers the features and flexibility of an equalizer and a preamplifier
control center. Professional-type slide pots and push-buttons are utilized
instead of the conventional rotary-type controls. The Mark Nine's operational
characteristics are much like those used in recording studios. The equalizers
may be used to compensate for porly equalized records, modify the tonal
characteristics of loudspeakers, and in some instances be used to compensate
for room characteristics.
Unique
Features
Professional-type
equalizer utilizing five frequencies instead of conventional tone controls.
Ten
torroidal LC bandpass filters with 12 dB/octave slopes.
Specially
designed slide controls assure the industry's most accurate tracking. Equalizer
and balance controls feature a center detent position.
Exclusive
tape-copy facility.
Program and
mode selections are made with push-buttons.
Equalizers
have dual range: variable to ±16 dB or ±8 dB.
An equalizer
defeat switch to electrically remove the equalizers from the circuit.
