AC Power Connection 8 Controls and Connection Because your Summit speakers use an internal power supply to energize their electrostatic cells and to power the PoweredForce™ woofers, they must be connected to an AC power source. For this reason they are provided with the proper IEC standard power cords. These cords should be firmly inserted into t ...

Single Wire Connection Controls and Connection 9 Please take note of the jumper clips installed under the binding posts. These clips attach the high and low fre- quency sections of the crossover together. Leaving these in place, connect the (+) wire from your amplifier to either red binding post and the (–) wire from your ampli- fier to either bl ...

10 Controls and Connection 1 Start with the 25Hz and 50Hz level knobs set to 0dB. The person at the listening position needs to become familiar with the sound at this setting. Remember, only the person in the listening position should judge the bass integration. Nodes and nulls change dramatically throughout every location in a room. A person adjus ...

By now your speakers should be placed approximately two to three feet from the front wall, the wall in front of the listening position, and about two feet from the side walls. Your sitting distance should be further than the distance between the speakers themselves. You are trying to attain the impression of good center imaging and stage width. The ...

ond. If your speaker system is not securely planted on th e floor or solid surface, it can shake as it produces sou nd and, consequently, the sound can be compromised. If your speaker is sitting on the carpet and only foot gliders are used, the bass can be ill defined and even boomy. The use of spikes is recommended to insure secured footing for yo ...

Your Summit’s launch a 30 degree horizontal dispersion pattern. This horizontal dispersion field gives a choice of good seats for the performance while minimizing inter- actions with side walls (see figure 10). Make sure both speakers stand exactly at the same vertical angle, otherwise the image can be skewed or poorly defined. The wave launch of ...

16 Home Theater It had long been the practice of stereo buffs to connect their television to a stereo system. The advantage was the use of the larger speakers and more powerful amplifier of the stereo system. Even though the sound was greatly improved, it was still mono and limited by the broadcast signal. In the late 1970’s and early 1980’s tw ...

20 Electrostatic History In the late 1800’s, any loudspeaker was considered exotic. Today, most of us take the wonders of sound reproduction for granted. It was 1880 before Thomas Edison had invented the first phonograph. This was a horn-loaded diaphragm that was excited by a playback stylus. In 1898, Sir Oliver Lodge invented a cone loudspeaker, ...

Electrostatic History 21 In 1947, Arthur Janszen, a young Naval engineer, took part in a research project for the Navy. The Navy was interested in developing a better instrument for testing microphone arrays. The test instrument needed an extremely accurate speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase ...
