1 INPUT 1, INPUT 2...INPUT 12 jacks
Connect mic or line sources (such as keyboards) to these input jacks.
Both XLR jacks and balanced 1/4" TRS phone jacks are provided.
You may also connect unbalanced phone plugs to the 1/4" jacks.
You can use either XLR connectors or TRS phone connectors for INPUT 1 through 8.
If you need to supply phantom power to condenser mics, connect them to the XLR connector.
Each XLR jack can provide +48V phantom power for condenser mics. The LED located below each
XLR jack will light if phantom power is switched on for that jack.
The balanced XLR jacks for INPUT 1–8 provide +48V phantom power for use by condenser mics; you can switch
this on/off independently for each channel.
Your equipment may be damaged if you connect or disconnect a condenser mic with phantom power turned on. You
must turn phantom power off before connecting or disconnecting condenser mics.
2 Phantom power switch
INPUT 1–8
jacks provide +48V phantom power so that condenser mics can be used. Phantom
power is supplied to the balanced XLR jacks, and can be selected independently for each channel.
Turn this switch on only for channels that use a condenser mic.
If a condenser mic is connected or disconnected with the phantom power switch on, damage to your equipment
may occur. For this reason, always turn the phantom power switch off before connecting or disconnecting a con-
denser mic.
If the phantom power switch is on, you must never connect any device other than a condenser mic. Doing so may
damage your equipment.
