4. Power Switch and LED
Press this switch to turn the M48 on and off.
The power LED will illuminate green when the M48
is turned on.
5. Low Battery LED
This LED will illuminate green to let you know that it’s
time to replace the 9V battery. And no, don’t test it by
putting your tongue on the battery terminals. The LED
is a fine indicator by itself...

The M48 may be powered by a single 9V battery. The
battery compartment is located on the bottom panel of
the M48 and is accessible by sliding and removing the

Warning
Beware of imitators! There’s a fake M48 out there.
Called the M4.8, it only supplies 4.8V of power instead
of the required 48V that condenser mics require.
