Back Panel Description: Kav-250A - Krell Industries Three-Channel Power Amplifier KAV-250a/3 Instructions For Use Manual

Back Panel Description: KAV-250a
See Figure 2 on page 6
The KAV-250a back panel provides connections for all inputs and outputs, remote
control input and output links, and AC power supply. Inputs and outputs labeled left and
right are on the left and right side of the amplifier, respectively, when viewing the
amplifier from the front panel.
Balanced Inputs
3, 4 Inputs
These are the right (3) and the left (4) KAV-250a channel inputs for output devices
balanced XLR connectors.
Single-ended Inputs
5,6 Inputs
These are the right (5) and the left (6) KAV-250a channel inputs for output devices
single-ended RCA connectors.
The left balanced or single-ended inputs are used for bridged operation. See
Reconfiguring the KA V-250a for Bridged Operation, on page 20.
Amplifier Channel Outputs
7 Output Bridged(-)
8 Output Bridged(+)
These are the right (7) and left (8) KAV-250a amplifier channel outputs with five-way
loudspeaker binding posts. The loudspeaker binding post terminals accept spade lugs,
bare wire, banana plugs, or pins. Use the red terminal for the positive connection and
the black terminal for the.negative connection. For information on loudspeaker
connections for bridged operation, see Reconfiguring the lEA V-250a for Bridged
Operation, on page 20.
Fuses
9 AGC-12 Fuses
The AGC 12 Volt loudspeaker fuses protect the KAV-250a against short circuits in
loudspeaker output.
10 Line Fuse
The line fuse protects the KAV-250a against short circuits in internal power supplies.
Note
Fuses must be replaced with the fuse value specified on the KA V-250a back panel. Use
a 20 amp slow-blow line fuse for 100/120 V systems or a 12 amp slow-blow line fuse for
220/240 V systems.
