Once the amplifiers are in place and turned off, connect the speaker and interconnect cables. The preamplifier should be on at this point, with level fully attenuated; all other sources should be off. Connect the AC last.

OPERATION

When turning on the system, the amplifiers should always be last. The KMA-160 on/off switch is actually a circuit breaker that is involved in several protection circuits. Upon turn-on the amplifiers'

outputs are not connected to the speaker. After the protection circuits have determined that the unit has completely stabilized, the speaker relays will be engaged. You will hear a click when at this point. The amplifiers are now ready to use. The amplifiers will be at temperature and sound their best after approximately 15 minutes.

Operating the amplifiers is, obviously, very easy. Equally important

is an understanding of the care that should be exercised when operating the system as a whole, in relation to the enormous power output of the KMA-160. Simple mistakes, such as switching between

active sources without muting the preamplifier output, or

bumping/miscuing a cartridge, can generate large transients at low

frequencies. With this type of transient the KMA-160 can generate

enough power to damage most loudspeakers. All switching of sources

should be done with the preamplifier level either muted or fully attenuated. Also, the inputs to the amplifiers should not be changed while they are on.

Care must be taken when setting high playback levels. Because of

their tremendous reserve of clean power, KRELL amplifiers safely drive speakers to higher sound pressure levels than other amplifiers. This also means driving them to their limit. Always turn the level down at the first sign of distortion.

When turning the system off, the amplifiers should be first. This

avoids the possibility of a turn-off transient from some other component getting to the speakers.
