Line/DI (Input 2)
The Line/DI input accepts line level signals, in-
struments, and other 1/4-inch TRS (Tip-Ring-
Sleeve) or TS (Tip-Sleeve) connections.
On the front panel, the input signal is adjusted
by the Input 2 Gain control. The source (Line or
DI) is chosen using the Line/DI switch on the
back panel.
Combo/DI Switch
This switch selects either the Mic/Line input for
channel 1 or the DI input for channel 1. When
pressed in, the channel 1 DI input is selected.
When not pressed in, the channel 1 combina-
tion jack connector is selected.
Phantom Power (+48V) Switch
When pressed in, +48V phantom power is active
on the Mic XLR input. Phantom power is pro-
vided for microphones that require it to operate.
About Phantom Power
Dynamic microphones (such as a Shure SM57)
do not require phantom power to operate, but
are not harmed by it. Most condenser micro-
phones (like an M-Audio Solaris) do require
phantom power to operate.
If you are not sure about the phantom power re-
quirements for your microphone, consult your
microphone’s documentation or contact the
manufacturer.
Mic/Line (Input 1)
The channel 1 Mic/Line input on the back panel
provides Mic (XLR) and Line (1/4-inch TRS) on a
combination jack. Switch between channel 1
Mic/Line and channel 1 DI using the Combo/DI
switch on the back panel.
Although phantom power can be used
safely with most microphones, it is possible
to damage some ribbon microphones with
it. Always turn off phantom power and wait
at least ten seconds before connecting or dis-
connecting a ribbon microphone.
When using phantom power, Mbox Mini’s
maximum current per microphone is 4 mA.
