4.1 MONO MIC/LINE CHANNELS 1 These are channel 1 through channel 4. 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.
4.7 3-BAND EQUALIZER A 3-band equalizer is provided for each input channel with a wide range of frequency adjustment. 7 EQ 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 12kHz. -15 8 -12 This is the midrange control. It can affect most fundamental frequencies of all musical instruments and human voice.
4.12 PEAK LED 14 Inside your AMX-180/AMX-180FX the audio signal is monitored in several different stages and then sent to the PEAK LED, when this LED blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK LED will blink with a level that is 6dB before actual clipping. 4.13 FADER 15 This control will adjust the overall level of this channel and set the amount of signal sent to the main output.
4.19 CTRL ROOM OUTPUT 21 These 1/4" sockets are used to send the control room signal to the studio monitor speakers or a second set of PA. 22 4.20 ALT OUTPUT These 1/4" sockets are unbalanced outputs, the signal level to the ALT OUTPUT is adjusted by ALT 3-4 rotary on the front panel. 4.21 PHONES 23 This socket will send out the mix signal to a pair of headphones. 24 4.
4.30 POWER LED 32 This LED indicates when the power is on in your AMX-180/AMX-180FX. 4.31 SOLO MODE SWITCH 33 This button provides two modes: up for PFL (Pre-Fader-Listen) mode, down for AFL (After-Fader-Listen) mode. Engage the button, the output signal of soloed channel will follow the TRIM, EQ, FADER and PAN/BAL control, and the SOLO ACTIVE LED illuminates. Release the button to enter into PFL mode, the output signal of soloed channel is unaffected by the PAN/BAL and FADER control. 4.

5. INSTALLATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate your AMX-180/AMX-180FX. However, we advise you to read carefully the following section to be the real master of your own mixer. Not paying enough attention to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all.
5.1 Audio Connection Both XLR and 1/4 " TRS connectors are available on the unit. In this way you can interface the unit in several different ways without experiencing any noise or signal loss. You can use the unit with single instruments using The mixer's main insert or on "in-line" between a mixing console's output and a power amplifier.
- Insert Points Connection If you are connecting to a mixing console's main inserts, you may have a single TRS jack for Send and Return, in this case, use an insert "Y" cable that configured like the examples below.
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.
