(To Remove the Preamplifier from the Shipping Box continued)

2.Carefully remove the preamplifier chassis, power supply chassis, and acces- sories from the box.

3.Place the the preamplifier chassis and power supply chassis in a safe location and remove the protective plastic wrapping.

4.Place the power supply chassis where you intend to use the assembled pre- amplifier.

Krell recommends that you place the preamplifier chassis on top of the power supply chassis. You can make 2 identical preamplifier/power supply stacks, as individual left and right channels, or one 4-chassis stack, with both channels combined in one stack.

5.Repeat Steps 1-5 for the remaining preamplifier channel(s).

Placement

Before you install an Evolution Two preamplifier into your system, please follow the guidelines in this section to select a location for your component. This will facili- tate a clean, trouble-free installation.

The Evolution Two preamplifier does not require a special rack or cabinet for installation. Each preamplifier channel measures 17.3 in (43.8 cm) wide by 7.3 in. (18.5 cm) high by 18.5 in. (47 cm) deep.

The Evolution Two preamplifier requires at least 2 inches of clearance on each side and at least two inches of clearance above the component to provide adequate ventilation. Installation inside cabinetry may require additional ventilation.

AC Power Guidelines

The Evolution Two preamplifier has superb regulation and does not require a dedi- cated AC circuit. Avoid connections through extension cords or multiple AC adapters. High quality 15 amp AC strips are acceptable. The use of AC line condi- tioning devices is not recommended. The features provided by these devices are already on board the Evolution Two. For more information, see Separate Power Supply, on page 7.
