SECTION THREE

Quick Start

To access the full array of available functions for the Evolution Two Monaural Preamplifier, please read the entire owner’s reference manual. The abbreviated routine in this Quick Start section will allow you to connect and operate the Evolution Two quickly and enjoy its basic functions.

Evolution Two preamplifier channels may be operated independently, or they may be operated in linked mode, using CAN Link.

Connecting the Evolution Two to Your System

Position each power supply and preamplifier chassis where you intend to use connected channels. Do do not move the chassis after they are connected.

1.Connect the power supply chassis and the preamplifier chassis with the 12-pin DC cable provided, using the DC power connectors (47) on the back panels (1-2).

IMPORTANT

Never connect two power supplies together.

2.In order to operate the Evolution Two preamplifier in linked mode, connect the preamplifier channels together with the supplied RJ-45 control cable. In linked mode, functions including power, volume, balance, phase, record, mute, and input selections are instantaneously transmitted between linked preamplifier channels.

When a system with linked preamplifier channels is powered on, left/right ori- entation is established immediately, with no user intervention. For more infor- mation on linked preamplifiers, see Appendix: CAN Link and Multiple Evolution Two Preamplifiers, on page 51.

3.Neatly arrange and organize wiring to and from the Evolution Two preamplifier and all components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being introduced into the system.

4.Connect the outputs of your source equipment to the appropriate CAST (34), balanced (30), single-ended (31), or tape inputs (32, 33) on the Evolution Two.

5.Connect the appropriate main outputs (35-41) on the Evolution Two to your amplifier.
