D. INPUT AND OUTPUT CONNECTIONS CAUTION: When making connections to this component or any other, make sure the power amplifier is OFF and the preamplifier is in the MUTE or STANDBY mode. 1. Connect the speaker cables .to. the output terminals of the amplifier.
Thepin assignment for the XLR is: pin _1-= shield (ground) . p!n 2 = non-inverting ~nput (hot) p~n 3 - inverting input NOTE: The RCA center conductor for each channel is wiredjn, parallel with pin 2, the non-inv.erted input. Only one ot tlaese inputs should be connectecl to a preamplifier.
Eo AMPLIFIER OPERATION 1. Push the black breaker type switc.h on the front of the amplifier to turn it on. The LED in the switch will illumi- nate. When turning on the system, the a _m, plifier should always be last. Upon turn-on, the amplifier s outputs are not connectedto the speakers.
E PROTECTION CIRCUITRY There are no fuses in the KST-100. The amplifier is protected by a series of non-intrusive, opto-c_o, upled circuits that constantly evaluate the amplifier s operation. Appropriate protective action exists for DC conditions, short circuit, oscillation, AC power anomalies, high ground resistance and out-of:phase ground.
G. MONAURAL CONVERSION AND OPERATION The KST-100 can be easily cgnverted into a 400 watt monaural amplifier. To switcla the amplifier to mono follow these instructions. 1. Remove the topcover from the amplifier via 8 topcover screws. 2. Find the toggle switch located at the rear of the ampli- fier mounted on the circuitboard.

I. OUESTIONS AND ANSWERS Q. Should I leave the KST-100 ON at all times? A. Althou.gh you could leave the KST-100 ON at all times without fear of damage to the amplifier, we recom- mend 30 minutes of warm-up_ before critical listening and switching the amplifier off when not in use.
Q. After the amplifier is playing for about one hour it becomes very hot. Is this normal? A. Yes. Due to the design of the KST-100 it will become quite warm when driven hard. If the amplifier should have a severe temperature inbalance between the left and fight channel, unplug the unit and call your authorized dealer or Krell.
