Figure 8. Access to control panel.

The K2 S5800 has two switches mounted on the network panel on the rear of the enclosure.

The switches are covered by an access plate which is easily removed by unscrewing the two mounting screws. See Figure 8.

The Network Mode (Bi-Amp) Switch ™(center) should be left in the Normal position except when bi-amplification with an external electronic crossover is to be employed. The necessary cross- over slopes for the K2 S5800 are very specific and bi-amping the sys- tem should only be done using fac- tory-approved electronics.

The HF Trim Switch £ (right) adjusts the high-frequency level over the range of approximately 1000Hz to 10kHz. The +1dB position gives the highest HF output and measures the most level. 0dB reduces the HF level by 1dB and the –1dB position reduces the HF level by an additional 1dB.

Although the range of these con- trols is rather small, each of them operate over a reasonably wide frequency range and thus have a noticeable effect on the overall tonal balance of the system. It is recommended that the system first be played with the switch in the middle position. This setting gives the most uniform measurements in a controlled environment. Of course, we are interested in pro- ducing the most pleasing sound in your environment with your choice of program material. It is, therefore, recommended that the HF Trim Switch £ be tested in its various settings on a variety of program material. Once you become familiar with their individual character, you should have no difficulty determin- ing the setting which produces the most pleasing, natural sound in your room with your equipment.
