Using this EQ is a great way to get a bit more oomph out of your vintage speakers.

Super cool 1/2 Octave EQ from the 1970s in a 19" Rack Mount form factor. Produced only two years from 1975 - 1977. 

When testing this unit we noticed the high-quality individual wire wound inductors that are usually only found in high price EQ's.  

This unit was fully reviewed and tested in our in our lab and is working properly.  It received a light service.

More from SAE:
The Mark 2700B presents a new level of frequency control. 

This stereo half octave equalizer is the result of many years of SAE experience in both home and professional equalizers. 

Several of the features of the 27B/2700B stand out as being unique in the industry such as: 

1. Half Octave Control - With the Mark 2700B, you now have the flexibility of frequency control on a half octave basis offering proper control not only of program material as in our previous equalizers, but also room acoustics and speaker deficiencies. 

2. Low Distortion - Utilizing full, complementary output drive circuits, we are able to offer an equalizer with TH and IM distortion of less than 0.02%. 

3. Pink Noise Generator - This is the most accurately known method of properly equalizing speaker phasing, power balance, and frequency response. 

4. Professional and Home Versions - Our half octave stereo equalizer will be offered in our traditional gold anodized version (27B) for home use, as well as a 19" rack mount version (2700B) with black panel and rack handles. Both units have 600 Ohm output.

Brand Background:
Scientific Audio Electronics (SAE) was officially commenced in 1968 with a Partnership Agreement between Ted Winchester, Morris Kessler and Beth Winchester. They needed a logo, so Ted took out some Bishop Graphics PC board drafting tape and designed the stylized "S" and "E" symmetrical with the "A", SAE was born.

The Mark Two was no beauty, but it didn't have the "transistor sound" like other amplifiers of the day. Still it was difficult to sell an "orphan" power amp to the audio emporiums of the day. Their customers wanted the Marantz and Macintosh full-line with front panels/rack cases look. That changed with a review in Stereophile. Gordon Holt was reluctant at first to review the "orphan" amplifier that was not available nationally. On the telephone, in effect he said, "Well you (Ted) have made me curious and either you and your friends all have tin ears if you and they think it's the solid-state equivalent of the Marantz Nine or you've made the only solid-state amp worth buying. Gordon's most generous praise of the Mark Two in Stereophile most likely started the SAE legend. 

In the early 70's, Ted was designing and manufacturing graphic equalizers separately under Linear Transducer Designs (LTD) that SAE marketed through the mid 70's. All LTD manufactured SAE equalizers and SAE preamp-equalizers are identifiable by the "Copyright LTD 19XX" on every circuit board except the Mark 1B.
Along the way, Morris was joined by the likes of the great Ed Miller and James Bongiorno, to name just a couple. Morris sold SAE, Inc. in 1988 to a company that in turn sold it to DAC. They were trying to reach the masses and had the SAE TWO line built overseas. It was the beginning of the end for the SAE banner. 

James Bongiorno started GAS (Great American Sound) which also built some classic amps, like the Ampzilla & Grandson. Bongiorno sold GAS and started a third company, Sumo, and designed still more classic amps, and a tuner called Charlie the Tuner. Then in June of 1994 Morris Kessler and Mike Pontelle joined under the banner of Amplifier Technologies, Inc. ( ATI ) .

For almost two decades, SAE made some of the best known home audio amplifiers. In the early Seventies, if one wanted the best in solid-state amplification, SAE came to mind. Known then internationally as purveyors of open and musical products, SAE lingers in the minds of audiophiles old enough to remember as a company that really produced. These amps were so popular, they took Japan by storm way before single-ended tube amps became retro-cool in the land of the rising Sun.
