Krell Industries Input Connections, Installation, The KMA-160, four, sets, of five-way, These

Amplifiers dissipate much of the power they consume in heat. The KMA-160 should be installed in a location that provides unobstructed

ventilation. If you have to install the units on shelves or in a

cabinet, extra ventilation might be necessary. This can be easily done with fans in a variety of ways. Generally, with the front and rear open, 2 - 3 inches clearance each side and 8 inches above the amplifier, ventilation will be adequate.

The dimensions of the KMA-160 are: 23" wide x 22" deep x 9 high. The units weigh 80 pounds each; shipping weight is i00 pounds each.

INPUT CONNECTIONS

The KMA-160 has bo~h balanced and single-ended inputs. The balanced

input uses the 3-pin XLR connector and the single-ended input uses

the RCA connector. The pin assignment for the XLR's is: pin 1 = signal ground; pin 2 = non-inverting input; pin 3 = inverting input. The RCA connector is wired in parallel with pin 2, the non-inverted

input. Only one of these inputs should be connected to a preamplifier.

The input that is not connected to the preamplifier can be used as an

output to a second amplifier for power-biamp applications. Before proceeding with such an installation you should consult your Dealer or the factory.

INSTALLATION

After inspection of the amplifiers for any shipping damage they are

ready for instaila~ion. The wiring to and from the amplifiers, and all components in general, should be arranged in a neat, organized manner. Specifically, AC wires should be separated from audio wires. This avoids hum or other unwanted noise from being induced into the system.

The KMA-160	has	four	sets	of five-way	binding	post speaker
connectors.	These	are wired	in	parallel and	have identical function.

It is always preferable to run long interconnect cables to the amplifiers and keep speaker cable length to a minimum. Speaker cable does add impedance between the amplifiers, regardless of its guage. All KRELL amplifiers will drive the lowest impedances with ease. When

impedance is added in any significant amount, amplifier power is literally wasted in driving the cable, thereby reducing the maximum power that can be delivered to the speaker.

The feet on the KMA-160 can be used two different ways. They are made from machined aluminum and are supplied with separate rubber bottoms and mounting screws. The rubber bottoms can be screwed into the the feet for protection of fragile surfaces such as hardwood floors or furniture. For use on rugs we recommend using the feet without the rubber bottoms.
