ULTRA-DI DI100 User Manual
◊ To avoid switching noise, you should mute the desk channel before activating
the DI100. Same applies when switching between battery and phantom power
and vice versa.
The design of the DI100 includes four sturdy rubber feet which protect the unit
(even during a unplanned drop) and allow cables to run underneath. It also provides literally
a "ground lift" so that the unit can be stacked on top of another unit and other equipment
without creating ground loops.

(1) With the ON/OFF switch you can switch the battery power on and off to preserve
battery life. Switched off the ultra-di will still work on phantom power. Switched on,
the ULTRA-DI will automatically switch between battery and phantom power. When the
DI100 is operating on battery power the on/off LED will flash once every few seconds,
when operating on phantom power the LED will light up continuously.
(2) INPUT. Connect the source to this ¼" jack to receive the signal.
(3) To provide maximum flexibility the ULTRA-DI is also fitted with an unbalanced XLR input
to connect the source.
(4) LINK OUT. This is the unbalanced parallel output of the ULTRA-DI. Connect this to the
input of the backline or monitor amplifier.
◊ The ¼" jacks (input and link out) and the Input XLR are wired parallel, so any
connection as input will give the same performance.
(5) The -20 dB attenuation switches greatly increase the operating range of the ULTRA-DI.
From the low-level signals of a high impedance microphone or guitar to the hot speaker
terminals of a P. A. amplifier. Depressing both will give 40 dB attenuation.
