ULTRA-DI DI100 User Manual
◊  Only use the -20 dB switches if you are sure the ULTRA-DI is clipping (overloading) 
and not your mic pre-amp. Always use as little attenuation as possible to get the 
best possible signal-to-noise ratio.
(6) 
OUTPUT. This is the balanced microphone level output of the ULTRA-DI. Connection to 
the microphone input should be made with a standard high quality balanced cable. 
◊  Never connect pin 2 or 3 to pin 1 and never disconnect the shield from pin 1, 
or the unit will not work on phantom power.
(7) 
Use the GROUND LIFT switch to either connect the ground of input and output or 
keep them completely separate. Depending on the grounding of the connected devices 
linking or disconnecting will reduce hum or prevent ground loops. GROUND LIFT ON 
means no interconnection. 
(8) 
BATTERY COMPARTMENT. Loosen the screw to open the compartment and to replace 
the 9 V battery. When the ULTRA-DI is switched on battery power the LED blinks, when it 
stops blinking it is time to change the battery.
