Connecting

 

your

The

 

microphone

 

provides

 

a

connector.

 

 

You

 

can

 

connect

 

the

 

microphone

 

either

 

to

 

a

 

balanced

 

or

 

an

 

unbalanced

 

microphone

 

input.

  

XLR

 

sockets

 

on

 

mixers

 

or

 

other

 

equipment

 

are

 

almost

balanced

 

microphone

 

inputs.

 

Please

 

use

 

a

 

high

XLR

 

cable.

  

 

You

 

can

 

also

 

connect

 

the

 

microphone

 

to

 

an

 

unbalanced

 

jack

 

(mono)

 

input.

 

Use

 

a

 

cable

 

with

 

a

 

female

 

XLR

 

connector

 

and

 

a

 

1/4

Don’t

 

use

 

cables

 

longer

 

then

 

5

 

meters/16ft,

 

because

may

 

pick

 

up

from

 

magnetic

 

fields

 

like

 

power

 

lines,
