Placement

Before you integrate your new amplifier into your system, please review the following guidelines to choose the location for the component. This will facilitate a clean, trouble- free installation.

The amplifier requires at least two inches (5 cm) of clearance on each side and at least two inches (5 cm) of clearance above and below the component to provide adequate ventilation.

The amplifier

does

not require any type of special rack or cabinet for installation. For the

dimensions of

your

amplifier see

Specifications

, on pages 26 and 27.

Place the amplifier as close to the loudspeakers as possible and keep the loudspeaker cable length to a minimum. Loudspeaker cable adds impedance to the load the amplifier must drive, regardless of the cable’s gauge. Krell amplifiers drive the lowest impedances with ease, but long loudspeaker cables reduce the maximum power that is delivered to the loudspeakers.

AC POWER GUIDELINES

Krell recommends operating the amplifier from a dedicated 15-amp AC power line. Please contact your authorized Krell dealer, distributor, or Krell before using any devices designed to alter or stabilize the AC power for the KAV–2250 and KAV–3250.

`

Power Cord

The KAV–2250 and KAV–3250 should be operated only with the power cord supplied.
