    UNPACKING NOTE: Due to the extreme weight of the KSA amplifiers, it is strongly advised that unpacking and placement is completed by at least two individuals. 1. Open the box. 2. Fold back the flaps on all four sides of the box and carefully roll it over on to the exposed end. 3. Pull the box straight up and off exposing the foam packing material. ...

    BASIC INSTALLATION LOCATION Place the KSA on a firm level surface away from excessive dirt or moisture. When using custom racks or cabinetry, keep in mind the weight and ventilation requirements for these amplifiers. Ideally the amplifier should be placed as close to the speakers as possible. It is preferable to run long balanced interconnect cable ...

    BASIC INSTALLATION CABINETRY CONSIDERATIONS High bias amplifiers dissipate much of the power they consume in heat. Because the KSA- 100S/200S/300S utilize Sustained Plateau Biasing, they remain cool when not in use. When the KSA is in use, it can become quite hot. Therefore, the KSA should be installed in a location that provides unobstructed venti ...

    BASIC INSTALLATION AMPLIFIER FEET The feet on the KSA can be used in several different ways. They are made from machined Delrin and are supplied with separate threaded rubber bottoms. The rubber bottoms can be screwed into the feet for protection of fragile surfaces such as hardwood floors or furniture. For use on rugs, we recommend using the feet ...

    BASIC INSTALLATION 4. Connect additional amplifiers as described in step 3. 5. When the cables are all in place, point the remote control at the amplifier designated as Master and press the Power button. The amplifiers will all turn on at the same time. The meter display for each amplifier may vary. Manually change the meter display via the front p ...

    CONNECTIONS 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 STAND-BY mode. The wiring to and from the amplifier, and all components in, general, should be arranged in a neat, organized manner. Specifically, AC wires should be se ...

    CONNECTIONS The pin assignment for the XLR is: pin 1 = shield (ground) pin 2 = non-inverting input (hot) pin 3 = inverting input NOTE: The RCA center conductor for each channel is wired in parallel with pin 2, the non-inverted input. Only one of these inputs should be connected to a preamplifier. Do not attempt to use the single-ended and balanced ...

    OPERATION AMPLIFIER OPERATION Understanding the ’operation of the amplifier is 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 KSA. Simple mistakes, such as switching between active sources without muting the preamplifier ou ...

    OPERATION DESCRIPTION OF TURN-ON SEQUENCE When turning on the system, the amplifier should always be last. The KSA On/Off switch is part of a multi-level turn-on circuit that goes through several steps of protection. Upon turn-on, the amplifier’s outputs are not connected to the speakers. After the protection circuits have determined that the uni ...

    OPERATION SYSTEM NOISE CONSIDERATIONS AC grounding often becomes critical when connecting high performance audio gear. When mixing and matching audio components, each with their own ground potentials, a low frequency hum can become present in one or both speakers. This can often occur when introducing a new component into the system. If there is a ...

    OPERATION BIAS LEVEL METER The KSA amplifiers utilize Sustained Plateau Biasing, a proprietary KRELL design. The Bias display meter on the front panel of the amplifier displays which level of bias the amplifier is utilizing. Unlike sliding bias designs, Sustained Plateau Bias only changes level when the demand situation relative to input and source ...

    OPERATION FRONT PANEL METER BUTTON A small button beneath the Power button on the front panel controls Bias Meter display illumination. When engaged, the meter display will no longer indicate bias levels; only the Blue pilot LED will be visible. The Bias Level meter can also be turned on or off via the remote control. PAGE 16 ...

    OPERATION REMOTE CONTROL FUNCTIONS The KSA-100S/200S/300S are the first high performance amplifiers to utilize remote control functions. The amplifiers can be switched on or offand the meter function can be changed from your listening position via the hand- held remote control. The KSA remote control duplicates the front panel switches on the ampli ...

    OPERATION PROTECTION CIRCUITRY There are no fuses in the KSA. The amplifier is protected by a series of non- intrusive, opto-coupled 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. C ...

  • Krell Industries KSA-100S - page 19

    OPERATION Should the amplifier turn off when either output cable is connected, the problem is cable or speaker related. Check to make sure there are good mechanical connections on the speaker cabling and there are no frayed ends or wires shorting the output terminals together. Have your speaker cables checked and repaired if necessary by your deale ...

    QUESTIONS AND ANSWER Q. Should I leave the KSA on at all times? A. Because of Sustained Plateau Bias, the KSA can be left on at all times without fear of damage, excessive heat or excessive power consumption. The KSA amplifier however, is designed to be turned On/Off, and can do so without degradation. The amplifier will work at full performance wi ...

    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 spe ...
