8 AUX SEND (1, 2, 3, 4)
These are unbalanced jacks with a nominal output and im-
pedance of +4dB/600Ω. (AUX 1 and 2 are pre-fader, and
AUX 3 and 4 are post-fader.)
9 AUX RETURN (1L/MONO, 1R, 2L/MONO, 2R)
These are unbalanced jacks with a nominal input level and
impedance of +4dB/10 kΩ.
These jacks are usually used to receive the audio returned
from an effect unit such as reverb or delay, but they can
also be used as supplementary inputs.
If a plug is inserted only in L/MONO, the same signal will
be sent to both the L and R buses.

1 POWER switch

This switch turns on the power of the mixer.
When turning off the power of audio equipment, it is im-
portant to start with the device closest to the speakers.
(Normally, this will be the power amp.)
2 PHANTOM switch
This switch turns on/off the phantom power supply for all
channels.
Use this switch when you are using condenser
microphones.
When this switch is turned on, DC +48V will be supplied
to pins 2 and 3 of each INPUT A XLR connector.
If you do not need phantom power, be sure to leave this
turned off.
* It is safe to connect balanced dynamic microphones or
line level devices even if this switch is left on, but con-
necting unbalanced devices or devices whose trans-
formers are center-grounded will cause hum or
malfunctions.
