Connecting a Microphone

Attaching a Microphone to the

Mbox

There are several ways to use Mbox with a mi-

crophone, depending on the type of micro-

phone and cables that you use.

Some microphone cables use an XLR connector

to attach a microphone to an input (such as

those on the Mbox); other microphones use a

1/4-inch connector. If you have a choice, use an

XLR connector to connect the microphone to

the Mbox to yield better results.

Phantom Power

Some microphones require power to operate.

This power, called phantom power, is supplied ei-

ther by a battery in the microphone, or through

an audio interface (such as Mbox) that can sup-

ply power through the microphone cable.

Most condenser microphones (such as an AKG

C3000) require phantom power to operate. Dy-

namic microphones (such as a Shure SM57) do

not require phantom power to operate, but are

not harmed by it.

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

a ribbon microphone.

1/4-inch connector

The Mbox can only supply power through a mi-

crophone cable with XLR connectors. If you are

not sure about the phantom power require-

ments for your microphone, consult your mi-

crophone's documentation or contact the man-

ufacturer.

To use a microphone that has an XLR connector:

Plug your microphone cable into one of the

Source inputs on the back of Mbox. The inputs

are numbered from the bottom up, so Source 1

is the bottom input.

Set the Source to Mic (microphone) by press-

ing the Source selector on the front of Mbox un-

til the Mic LED is lit.
