4.1 MONO MIC/LINE CHANNELS

1

These are channel 1 through channel 8. You can connect balanced,
low impedance microphones or a low level signal to the XLR socket.
On the 1/4" line jack you can connect either a microphone or a line
level instrument such as synthesizers, drum machines, effect pro­cessors or any other line level signal.
Note: You shall never connect an unbalanced microphone to the
XLR socket if you do not want to damage both the microphone and
mixer. Also, it is not possible to simultaneously use both the MIC
&LINE inputs on the same channel, use only one of them for the
appropriate source.

PHANTOM POWER +48 VOLT

It is available only to the XLR MIC sockets. Never connect a mic­rophone when phantom power is already on.

4.2 MONO CHANNEL INSERT

2

Insert sockets are provided for all mono MIC channels. It can
allow you patch external signal processing devices into signal path
via a TRS connector, the signal will be taken out after the input
gain control (TRIM), and sent to an external processor such as a
compressor- limiter, then returned into the same channel imme­diately before the EQ section.
Note: Usually, insert connections require a special stereo-splitting
Y-cord to be connected, known as TRS connector (Tip Send/Ring
Return).

5

These are channel 9 through channel 16. They are organized in
stereo pair and provided with 1/4" TRS sockets. Use the left
input if connect a mono input signal to the STEREO INPUT.

4.6 +4dBu/-10dBV

6

These switches select the input sensitivity of the line inputs on the
stereo channels CH9 ~ CH16. +4dBu is suitable for professional
audio devices, -10dBV is suitable for general HI-FI devices. If not
sure to use which setting, try +4dBu first, or change it to -10dBV
if the volume is too small to be satisfied.

10

This control provides you up to 15dB boost or cut at 500Hz.

- LOW

11

This is the bass control. It is used to boost male voice, kickdrum
or bass guitar. Your system will sound much bigger than what
it is. The gain range goes from -15dB to +15dB and the center
frequency is 80Hz.

4.8 AUX SENDS CONTROL

12

These two controls are used to adjust the level of signal sent to
AUX bus1&2, and this adjustment doesn't effect the main mix
output signal at all.
AUX1 can be configured as PRE/POST fader via the PRE/POST
switch. Up for POST fader, the signal is sent out after the channel
fader and will be affected by the channel fader. Down for PRE
fader, the signal is sent out before the channel fader and will not
be affected by the channel fader. AUX2 is configured as POST
fader, however, it can also be configured as PRE fader through
internal modification. (For more detail, please refer to chapter 6)

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your AMX-220/AMX-220FX.
However, we advise you to read carefully the following section to be the real master of your own mixer. Not paying
enough of the signal will result inattention to the input signal level, to the routing of the signal and the assignment
unwanted distortion, a corrupted signal or no sound at all. So you should follow these procedures for every single channel:

Before connecting mics or instruments, make sure that the power of all your systems components including the
mixer is turned off. Also, make sure that all input and output controls of your mixer are turned down. This will avoid
damage to your speakers and avoid excessive noise.
Properly connect all external devices such as mics, power amplifiers, speakers, effects processor etc.
Now, turn on the power of any peripheral devices, then power up the mixer.
Note: the power amplifier or powered monitors shall be turned on after the mixer and turned off before the mixer.

75%.Set the output level of your mixer or the connected power amplifier at no more than
Set the CONTROL ROOM/PHONE level at no more than 50%.
Position HI, MID and LOW EQ controls on middle position.
Position panoramic (PAN/BAL) control on center position.

While speaking into the mic (or playing the instrument), adjust the channel Level control so that the channel PEAK

blink occasionally, in this way you will maintain good headroom and idea dynamic range.LED will
You can shape the tone of each channel by adjusting the equalizer controls as desired.
Now repeat the same sequence for all other input channels. The main LED could move up into the red section,
in this case yo can adjust the overall output level through the MAIN MIX control.
For AMX-220FX, you can select desired DSP sound effects via PRESET and VARIATION controls.

6. FOR THE EXPERTS WHO WANT TO KNOW MORE

As we have told you previously in this manual, the AUX SEND2 control both on mono and on stereo channels is factory
wired as POST-FADER. If you have some skill in electronic components soldering you can modify this setting and have
all your AUX SENDS configured as PRE-FADER.
