Musical Fidelity KW 500 manual Operation, Starting, Overload Protection, Tape Recording

STARTING . . . .

Press the POWER button on the front panel of the kW 500 power supply unit. The blue LED above the button should now light.

The LEDs in the feet of the amplifier unit will light red for about fifteen seconds indi- cating that all audio outputs from the unit are muted. Feet illumination then fades over approximately fifteen seconds to amber, indicating that output is no longer muted, and that your kW 500 amplifier is now ready for use. However, after a further period of about 35 minutes, the colour fades to blue, confirming that the amplifier has fully warmed up.

Unless using your amplifier for off-tape monitoring (see paragraph opposite ) ensure that the TAPE MONITOR button has not been pressed accidently, as other- wise no sound will be heard through the speakers.

Select the required audio input source by pressing an appropriate function button on the front panel, or remote control. Now adjust the volume control to obtain the pre- ferred sound level.

OVERLOAD PROTECTION

If for any reason, speaker output power of your kW 500 is excessive, for example at very high volume setting or due to wrong load impedance, an overload protection cir- cuit is activated. The motorised volume control will be turned down automatically, and the four illuminated feet will change colour to violet for about five seconds, or until the problem is removed.

OPERATION

TAPE RECORDING

To record, simply select the required source with the input selector button on the front panel or remote control. This source will now be routed to the kW 500’s TAPE RECORD output for recording by the external tape deck. You will also be able to hear the selected source through the loud- speakers.

Note - adjustment of the volume control has no effect on the recording level.

OFF TAPE MONITORING

The kW 500 Integrated amplifier has a sin- gle tape circuit with facility for off-tape monitoring with 3-head tape decks.

In conjunction with a 3-head cassette deck, off-tape monitoring allows the user to com- pare recorded sound with the original whilst a recording is being made. To do this, first select the required source in the normal way and start recording.

The TAPE MONITOR button on the front panel can now be used to switch between the original source sound and the recorded version, allowing direct comparison.

On some 3-head tape decks there is an addi- tional ‘tape/source’ switch, which must be in the ‘tape’ position for the above to work.

If in doubt, please refer to your tape deck operating manual.
