Battery Installation
A To install or replace the internal battery, first undo the knurled screw on the battery
compartment - DO NOT undo the flush panel screws.
The battery cover should now fold back towards the edge of the unit, revealing the
compartment. Attach the flying lead battery terminals to your battery, and slide the
battery into the compartment, with the connector towards the outside of the DI-BOX.
For best reliability and long life, we recommend you use only high quality alkaline
batteries in your DI-BOX.
Phantom Power
The DI-BOX can work reliably on a wide range of phantom power voltages, although of
course the typical supply provided by modern consoles is +48 volts.
The DI-BOX accepts supply voltages of +48 volts down to +20 volts without loss in
performance.
While the DI-BOX is receiving good phantom power, the power LED is lit continuously.
Should the supply fail for any reason, the DI-BOX will switch over automatically to run
from the internal battery (as long as one is fitted!). Under these conditions, the power
LED flashes approximately every 2 seconds.
Power ON/OFF Switch
The On/Off switch is used for both phantom power and battery. To avoid battery drain
when the unit is not in use, ensure that this switch is set to the upper OFF position
when storing or packing the DI-BOX.
Optionally, an internal link can allow phantom power to activate the DI-BOX regardless
of the On/Off switch setting.
This link must be changed by an Authorized Technician only. Please refer to your
Dealer/Distributor for details.
