A [PHANTOM +48V ON/OFF] switch
This switch supplies +48 V phantom power to the
INPUT (XLR) 1/2 jacks (2). Turn this switch ON
when condenser mics that require an external
power supply are connected to the INPUT 1/2
(XLR) jacks.
• This switch must be turned off if devices not requir-
ing an external power supply are connected to the
INPUT 1/2 (XLR) jacks.
• If the phantom power supply is turned on, power will
be supplied to both the INPUT (XLR) 1 and 2 jacks.
B INPUT 1/2 (XLR) jacks
These are XLR-3-31 type input jacks for connect-
ing balanced condenser mics or line level devices.
The nominal input level is +4 dB to –46 dB. The
pin wiring is as follows.
C INPUT 1/2 (TRS phone) jacks
These are balanced TRS phone input jacks.
Devices with unbalanced output, such as synthe-
sizers, can also be connected. The nominal input
level is –46 dB – +4 dB. The pin wiring is as fol-
lows.
• If plugs are inserted into both the XLR jack and TRS
phone jack of INPUT 1/2, the TRS phone jack will
take priority.
• Phantom power is not supplied from the INPUT 1/2
(TRS phone) jack.

These are balanced TRS phone input jacks. The
specifications of these jacks are the same as for the
INPUT 1/2 (phone) jacks.
E INPUT 8 (Hi-Z) jack
This is a high-impedance unbalanced phone input
jack. Instruments with a high output impedance
such as passive-type electric guitars can be con-
nected directly to this jack. The nominal input
level is –46 dB to +4 dB.
If plugs are inserted into both the TRS phone jack and
the Hi-Z jack for INPUT 8, the Hi-Z jack will take pri-
ority.
