SAE 2700B

 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.
