Krell Industries 900, 400 manual Connecting an Evolution Amplifier to Your System, CAST Connections

SECTION FOUR

Connecting an Evolution Amplifier to Your System

This section describes Evolution amplifier connections. Each Evolution amplifier channel has a CAST 4-pin connector, a balanced input via an XLR connector, a single-ended RCA connector, and a pair of loudspeaker binding posts. The rear panel also has 12 VDC trigger input and outputs, and a backlight remote trigger input. All inputs and outputs are located on the Evolution amplifier back panel.

Maintain the correct left/right orientation, when hooking up your system.

CAST Connections

Krell recommends using its proprietary Krell CAST system for unparalleled sonic performance for connections between the Evolution amplifier and other CAST- equipped components. Krell CAST uses flexible interconnecting cables that can be drawn through tight spaces and concealed.

Balanced Connections

The Evolution amplifier also offers balanced operation. The circuitry and connec- tions associated with balanced operation not only can minimize sonic loss but also are immune to induced noise, especially for installations using long cables.

XLR Pin Configuration

Pin 1	Ground
Pin 2	Non-inverting (0O) (hot)
Pin 3	Inverting (180O) (cold)

Single-ended Connections

Each Evolution amplifier channel has one single-ended input. If connecting a vacuum tube preamplifier, use the single-ended inputs only (see below). Connect the u-shap- ed jumpers between pins 1 and 3 of the XLR connectors when using single-ended inputs.
