Introduction Thank you for your purchase of.the Krell KAV-1500 Five-Channel Power Amplifier. The KAV-1500 amplifier provides substantial five-channel output power that delivers realistic music reproduction at an exceptional value.
Definition of Terms, continued Single-ended A two-wire input or output circuit, Use care when using single-ended connections, in which the ground, connection is made last and broken first. Turn the system off prior to making or breaking single-ended connections.
Unpacking Open the shipping box, which contains: 1 amplifier unit (packed in foam end-caps) 4 ribbon connection cables Fuses 2 AGC- ~ (~-amp) speaker fuse 1 slow-blow (20 amp for 100/120V or 12 amp fo.
Placement Before you integrate the KAV-1500 into your system, review the following guidelines to choose the location for the component. This will facilitate a clean, trouble-free installation.

Back Panel Description: KAV-1500 See Figure 2 on page 7 The KAV-1500 back panel provides connections for all inputs and outputs, remote connection input and output links, and AC power supply.
Back Panel Description, continued Fuses 19 AGC-12 Fuses The AGC 12 Volt loudspeaker fuses protect the KAV-1500 against short circuits in loudspeaker output.
Connecting the KAV-1500 Amplifier to Your System INPUT AND OUTPUT CONNECTIONS Follow these steps to connect the KAV-1500 amplifier to your system. 1. Make sure all power sources and components are off before connecting inputs and outputs= 2. Neatly organize the wiring between the amplifier and all system components.
The KAV-1500 amplifier is shipped with shorting pins in the XLR inputs. These pins should remain in the XLR inputs if the amplifier is operating in the single-ended mode. When the shorting pin is insert,ed, pins 1 (lower left) and 3 (top) are shorted together.
Optional System Configurations The KAV-1500 can be reconfigured for either Multi Amp Throughput (MAT) or bridged operation. IMPORTANT Removing the cover to reconfigure for MAT or for bridged operation is the ONLY instance you are authorized to remove the cover of ANY Krell component without voiding your Warranty.

BRIDGED OPERATION The KAV-1500 can be reconfigured to bridge four of its amplifier channels to operate as two combined amplifier channels. The bridged amplifier channels each deliver 1,100 Watts into an 8 Ohm load. The unbridged amplifier channel can be connected to a separate loudspeaker.
Connecting the Bridged KAV-1500 See Figure 2 on page 7 Connect the bridged channels as follows: Option 1 1. When the left and right channels are bridged, connect the output cable from the output device to the appropriate balanced (7) or single-ended (12) left channel input.
Multi Power Mode Connection Multi power mode is one possible connection scenario using the KAV-1500’s Multi Amp Throughput (MAT) feature. With Multi Power Mode, you can use the KAV-1500 reconfig- ured for MAT to independently power multiple pairs of stereo loudspeakers, to extend the listening environment throughout your home.
Amplifier Operation ON/OFF AND OPERATION When powering up your system, turn amplifiers on last. When powering down your system, turn amplifiers off first. The procedures for amplifier operation follow. 1. Press the power button (1) on the KAV-1500 front panel.
Questions and Answers Q. Should I leave the KAV-1500 amplifier on at all times? A. No. The amplifier does not have a stand-by mode. Leaving it on at all times would result in considerable heat output and power consumption.
