DI100 configurations
The next section will show several different ways the ULTRA-DI can be hooked up.

Guitar Amp/Mixer
This figure shows the standard application of any direct injection box. The signal
to the amplifier is unaffected, it is just tapped off to be routed to the microphone
input of the mixer. Especially bass guitars benefit from this application. It is
difficult to find a microphone which handles high level low frequencies well and
with a linear frequency response. Using the ULTRA-DI will give you clean and
crisp sound. Connect the ULTRA-DI after any effects devices so that their effect
will be heard over the P.A.-system or on the recording. If the mixer provides
phantom power between 20 V and 52 V, the internal battery of the DI100 will
automatically be detached. You should chose this possibility whenever possible
to save battery power.

Mixer
This configuration can be used with a keyboard, DJ-mixer, headphone output,
drum kit or any (stereo or mono) line source. In all cases where you want to
run long lines, for instance to the FOH (Front Of House) desk. In most cases the
best setting is achieved by depressing one of the -20 dB pad buttons to avoid
overloading the FOH desk input. The signal can be linked through to another
amplifier, if the keyboard player / DJ / etc. wants to have a monitor connected
independent of the foldback mix. The ULTRA-DI acts as both a ground isolator
and an unbalanced to balanced converter.

2.3
Converting a microphone from
high impedance unbalanced to low
impedance balanced
Sometimes all that's available (especially when all other mics are in use) is a
unbalanced high impedance microphone with an unbalanced jack. With the
ULTRA-DI long cable runs to the console can be established without fear of
picking up noise and hum. Just plug the jack into the input and connect the
output to the console's mic in.
2.4
Tapping a signal from a power
amplifier output
When no line out is available it is possible to connect an amplifier output directly
to the DI100 (for example, recording direct from a guitar amplifier, TV-speaker,
etc). It is possible to connect the output, i.e an extra speaker output, of up to
3000 Watts to the ULTRA-DI without fear of overloading. Pay attention to the two
-20 dB buttons on the ULTRA-DI! Both must be depressed if an amplifier output is
connected to the DI100 input.

Fig 2.3: Connection to an amplifier output
always make sure the ground lift is on (no ground link) when connecting
to speaker terminals. This prevents accidental short-circuiting of the
amplifier output. also make sure the Tip of the input jack is connected to
the red terminal and that the metal housing of the DI100 has no contact
with other equipment.
