If you have an electro-acoustic guitar, it will
probably have a standard guitar jack socket. You can not directly connect
this to a mixer as the signal levels will not be matched and it will sound
pretty awful.
You need to go via a direct injection box. You plug
the guitar in to this and then use the DI boxes XLR output socket to connect
to the mixer using a balanced XLR cable.
DI boxes are pretty inexpensive.
What Type of DI box do we need?
There are 2 basic types, Active and Passive. Active
are powered by a 9v
battery.
We would always recommend active DI boxes as these
allow you to boost or cut the balanced signal and cost the same amount of
money. We would also recommend that you get one with a
'ground lift' switch which can be useful if you get mains hum (see
Avoiding
mains hum).
Passive DI box. Jack input with parallel "THRU" output, transformer
balanced XLR output. Attenuable input sensivity, can handle both line
level and speaker level singals.

Using a Microphone
This is really only an option if you are playing as
a solo artist or in a duo. For best performance, use a dynamic cardioid type
