unit does not supply a charging circuit. You must
remove the discharged battery to recharge it with
an external charger. We recommend using long life
alkalines. The internal battery is replaced by remov-
ing 4 screws holding the bottom cover. You can
expect from 100 to 150 hours of continuous use from
a fresh alkaline battery. Useful life is ended when the
battery voltage drops below 5.5 volts.
To extend battery life, always unplug the input
when the unit is not in use.
should normally be grounded. Don’t lift the ground
unless it actually eliminates hum or buzz.
e. External Power
When external power is used, the internal battery
becomes disconnected and will not experience a
power drain. A wide range of both a.c. and d.c.
supply voltages is acceptable for power (see speci-
fications) and it does not matter whether the center
pin is positive or negative. Almost any existing foot
pedal or stomp box power unit will work as long as
the plug fits the jack. The power jack fits a standard
6MM x 2MM power plug as used by most
popular stomp boxes.
f. Phantom Power
With all pedals built after February 2004, phan-
tom power applied to the D.I. will supply reli-
able power.
Do NOT operate the ground lift switch
when running on phantom power. It makes a hor-
rendous click like plugging in a mic!
f. 9V Battery
You can use any type of 9V battery that fits the snap
