NTi Audio Digirator DR2 - Manual (Page 11)

Overview
Power supply
Battery operation
In order to be always able to use the Digirator flexibly, we rec-
ommend the use of batteries.
Only use 3x AA, LR6 batteries.
The battery consumption increases
at higher levels and is based on the
connected load.
During operation, the battery temperature
may increase noticeably. This is not a
defect.
The instrument can also be used with
rechargeable batteries.
Operation using mains power supply
You can also connect the Digirator to mains power with a
DC power supply unit. To do this, you will need the correspond-
ing DC power supply accessory unit, which you can order from
NTi Audio.
We recommend you use only the NTi Audio
DC supply. But if you want to make use of
a different DC power supply unit, you must
observe the following:
Use an electrically-isolated, non-earthed
linear DC power supply unit with
2.1 x 5.5 x 9.5 mm plug and connection
. Only use DC power supply units
with a voltage from 5 to 8 volts and a
current of at least 500 mA.
Do not use a switching power supply.
Unbalanced connections in combination
with a switching power supply can lead to
noise interference and an unpleasantly high
interference level when plugging in and
out.
Damage caused by using an inappropriate
external DC supply is not covered by
warranty.
