9.1.3. MIC 2 – 6 connections
Microphones equipped with either an XLR connector or a phone plug can be used with microphone inputs 2 – 6.
• Balanced or unbalanced microphones can be connected to the phone jack.
• Switching ON the phantom power switch supplies power to all MIC 2 – 6 XLR connectors.
• No phantom power is supplied to the MIC 2 – 6 phone jacks.
Tip
When phantom power is used for the MIC 2 – 6 XLR connectors,
a 24 V voltage is applied to Pins 2 and 3 in each connector.

Microphone sensitivity is as follows:
MIC 2 – 4: −66 dB (high sensitivity)
MIC 5 – 6: −60 dB
For microphones connected to MIC 2 – 4, it is assumed
that the microphone will be mounted on a microphone
stand and used at a distance from the speaker's mouth.
For microphones connected to MIC 5 or 6, it is assumed
that the microphone will be used close to the speaker's
mouth.

Note
Do not simultaneously connect microphones to the XLR connector and the phone jack of the same number.
Input signals to the microphone input may be attenuated, potentially disabling normal use of these connectors.

In this figure, since a microphone with a phone plug is
used for MIC 6 input, the phantom power is not supplied.
