tors are useful for easy check of signal levels and level
change (setup by use of the level switch !1).

Phantom Power Switches [PHANTOM ON/OFF]
When this switch is toggled on, the phantom power
(+48 V) is supplied to a condenser microphone.
Therefore, toggling the switch on allows a condenser

Cautions:
• Toggle the switch on only when using a condenser
microphone that requires external power supply.
• Refer to the operating instructions for a condenser
microphone when using it.
• Connect a condenser microphone after adjusting
the input fader to "0" in order to prevent noise occur-
