Powering On And Off - Yamaha A4000 Owner's Manual

Powering On and Off

This section explains the correct procedures for powering up and powering down your equipment.
Power ON
• Speakers or amplifiers should be switched on last to protect against unexpected sound surges
that may damage your equipment.
[Procedure]
1.
Switch on power to external MIDI and SCSI devices.
• When powering up MIDI devices, it is generally good practice (although not strictly necessary) to switch
on the transmitting-side device first.
• If you are switching on a SCSI disk or CD-ROM drive, allow the drive a few seconds to get up to speed
before proceeding to Step 2.
2.
Switch on the power to the A5000/A4000. (Press the POWER switch on the front panel.)
3.
Switch on power to speakers and other audio devices.
Power OFF
• Like other samplers, the A5000/A4000 stores all new data into main memory only, and will lose all
of this data when you switch off the power. You must therefore save all important data to disk
before turning the A5000/A4000 off.
• Speakers or amplifiers should be switched off first to protect against unexpected sound surges
that may damage your equipment.
[Procedure]
1.
Switch off the amplifiers or speakers.
2.
Switch off the power to the A5000/A4000. (Press the POWER switch on the front panel.)
3.
Switch off external MIDI and SCSI devices.
