Fuse Rating
The fuse rating displayed here, refers to the rating of the mains inlet fuse.
For more information on fuse ratings, please refer to Chapter 13
“Specifications”.
Caution! Never replace the fuses with any other ratings other than the one
specified.
AC Mains Input
An IEC-standard mains input is provided at the rear of the unit. The AC cord set
is removable, allowing you to upgrade to a cord set of your preference.
Caution! Prior to connection to the AC mains, please check the voltage label on
the rear panel to ensure that your unit conforms to the power supply in
your area. Never attempt to connect the unit to the incorrect voltage.
Severe damage can result from applying incorrect voltage to the unit.
Earth Lift Switch
This switch enables the user to isolate the internal signal earth of the amplifier
from the mains earth and is useful if system hum is a problem. Setting this
switch DOWN connects the internal signal earth to mains earth and is the normal
position. Setting to UP disconnects the signal earth from the mains earth.
Note: Activating this switch has no effect on chassis earth, maintaining the
connection to mains earth.
Mains Fuse
The 750 is equipped with a user serviceable AC mains fuse. In the event of fuse
failure, always replace with the same type and value fuse. Remember, fuses do
not usually blow without a reason. Any doubts about fuse failure should be
conveyed directly to your Perreaux dealer.
For more information on fuse ratings, please refer to Chapter 13
“Specifications”.
Caution! This is the ONLY user accessible fuse.
Never replace the fuses with any other ratings other than the one
specified on the rear panel.
Always ensure your 750 is disconnected from the mains supply before
attempting to change the mains fuse.
Master Trigger Input
The master trigger input is used to take the 750 in and out of standby. The
master trigger input is designed to accept a 3.5mm diameter male plug. The
voltage rating is +5V to +12V DC level ON and 0V DC level OFF.
