48 Volt phantom power
It is available only to the XLR Mic sockets. Never plug in a microphone when
phantom power is already on. Before turning phantom power on, make sure
that all faders are all the way down. In this way you will protect your stage
monitors and main loudspeakers.

This control is provided with 2 different indication rings: One is for the mic-
rophone and the other for the line levels. When you use a microphone you
shall read the OUTSIDE ring (0~44 dB), when you use a line level instrument
you shall read the INSIDE ring (+15~-30 dB). For optimum operation you
shall set this control in a way that the peak LED will blink also occasionally
in order to avoid distortion on the input channel.
-. 3 BANDS EQUALIZER
A 3-band equalizer is provided for mono input channels with a wide
range of frequency adjustment.
HI
This is the Treble control. You can use it to get rid of high frequency
noises or to boost the sound of cymbals or the high harmonics of
the human voice. The gain range goes from -15dB to +15dB with
a center frequency of 12 kHz.
MID
This is the Midrange control. It can affect most fundamental fre-
quencies of all musical instruments and human voice. An attentive
use of this control will give you any very wide panorama of sound
effects. The gain range goes from -12dB to +12dB and the center
frequency is 2.5 kHz.

These are channel 1 through channel 2. You can connect balanced, low impe-
dance microphones to the XLR socket. On the 1/4" jack you can connect either
a microphone or a line level instrument. You shall never connect an unbalanced
microphone to the XLR socket if you do not want to damage both the micro-
phone and the mixer.
