Questions and Answer

Q. My speakers axe only rated for 150 watts, is the KSA-200 or KSA-300 going to be too much power for them?

A. Seldom do you break a speaker by over powering it. Usually lower powered amplifiers will clip driving a loud speaker during heavy demand situations

and consequentially damage the speaker. KRELL amplifiers can break speakers, but a responsible listener should know the limitations of his/her

system and exercise caution. The higher powered KRELLamplifiers will sound better because of the increased control over the speaker. Should you have any questions contact your dealer or the KRELLstaff for assistance.

Q. When I connected the KSA to my system with the single-ended inputs a loud buzz came through my speakers. Is the amplifier broken?

A. The KSA has special shorting pins in the XLR inputs that enable the amplifier to function properly with the single-ended inputs. If the shorting pins are not inserted between pin 1 and 3 the 180 degree input will be open to excess noise.

Otherwise single-ended inputs will work fine with the unit. The performance of the amplifier is much improved when using the balanced inputs.
