Professional
Dual-Channel Half Octave Equalizer
The result
of years of SAE experience in home and professional equalization. Here are some of the outstanding features of
the 2700B:
Half Octave
Control
Professional
slide potentiometers provide for individual adjustment of 20 frequencies per
channel on a half octave basis. In combination with a switchable ±8 dB or ±16
dB gain range, these half octave controls allow for extreme levels of
flexibility-up to 32 dB of adjustment per frequency. This control design offers
peaked response when used in extreme position, thus overcoming individual
resonance problems without compromising other frequency regions. This high
level of frequency control allows for proper equalization of program material
as well as correction of poor room acoustic and speaker deficiencies,
especially at crossover points.
Pink Noise
Generator
A built-in
pink noise generator assures an accurate reference for proper equalization of
wide band speaker response, speaker phasing, channel power balancing and
frequency equalization.
Amplifier
Stage
The SAE
2700B professional Equalizer output amplifiers incorporate a full complementary
output stage, overcoming limitations of the more commonly used single ended
output amplifiers. This output amplifier circuitry offers full voltage swing
even into low Z loads, full symmetry clipping and at high output levels, there
is no slew limiting. The 2700B also delivers 11 volts RMS into 600 ohms load
assuring adeguate drive voltage under any condition.
Low
Distortion
Full
complementary output drive circuits provide total harmonic and intermodulation
distortion levels of less than 0,02%
Low Noise
High Q
Toroid inductors in combination with low loss capacitors and low noise
professional slide potentiometers result in circuitry offering greater than 100
dB S/N ratio and accurate equalization curves.
IC Power
Supply.
Individual
IC control for positive and negative power supplies further assures low noise
circuitry and stability with changing line conditions.
The SAE
2700B Dual-Channel Half Octave Equalizer
delivers +23 dBm for recording applications, offers complete control, extremely
low noise, accurate equalization, and the usual superb SAE quality.
