See Figure 4 on page 10

20 Handle

All Full Power Balanced monaural amplifiers are equipped with a handle, located beside the speaker binding posts, to help you easily and safely move the amplifier.

21 Speaker Binding Posts

Full Power Balanced 750Mcx, 450Mcx, and 350Mcx monaural amplifiers are equipped with two pairs of speaker binding posts (one upper pair and one lower pair). For stereo operation, two monaural amplifiers are required.

22 Krell CAST Input

Full Power Balanced 750Mcx, 450Mcx, and 350Mcx monaural amplifiers are equipped with one Krell CAST input via a 4-pin bayonet con- nector. The Krell CAST input allows the Full Power Balanced amplifier to be connected to the KPS 25sc Krell Playback System and other CAST-equipped components.

23 Balanced Input

Full Power Balanced 750Mcx, 450Mcx, and 350Mcx monaural amplifiers are equipped with one balanced input via an XLR connector.

24 AC Mains Power Cord

All Full Power Balanced amplifiers are equipped with a permanently attached AC power cord.

25 Krell Link Out/In

Full Power Balanced amplifiers are equipped with Krell Link Remote out/in connectors that allow the remote control to operate a linked amplifier configuration. See Krell Link Connec- tions, on page 13 for more information.

Note

An optional remote control is available for Full Power Balanced amplifiers.

26 Back Panel Power Breaker Switch

Full Power Balanced amplifiers are equipped with a back panel power breaker switch, for powering on the amplifier. Powering on using the back panel power breaker switch places the amplifier in stand-by mode, where it remains until the front panel power button is pressed.

Note

Krell recommends that, once the amplifier is powered on from the back panel power breaker switch, it remains on, in stand-by mode, even when not in use.
