a. Please check the AC voltage available in your country before connecting your

AMX-100(FX) to the AC socket.

b. Be sure that the main power switch is turned off before connecting your

AMX-100(FX) to the AC socket.

Also, you should make sure that all level controls are turned down, This will avoid damages to your speakers and also avoid excessive noise.

c. Before disconnecting your AMX-100(FX) please turn-off the power switch first.

d. Do not use solvent to clean your AMX-100(FX) using dry and clean cloth will be fine.

e. Before turning on your AMX-100(FX), you shall connect it to a power amplifier and

turn-on the AMX-100(FX) BEFORE the power amplifier. Once you have finished your working session, you shall turn the mixer off AFTER the power amplifier.

NOTE:

Never try to connect a line-level signal to the XLR MIC input when

This control is provided with 2 different indication rings: one is for the MIC and the other for the LINE input. When you use a Microphone, you shall read the OUTSIDE ring (0~44dB); when you use a line level instrument, you shall read the INSIDE ring (+15~30dB), For optimum operation, you shall set this control in a way that the PEAK LED will light up only occasionally in order to avoid distortion on the input channel.

4. CONTROL ELEMENTS

EQUALIZATION

You have three EQ control for each mono and stereo input channel each providing +/-15dB of boost and cut (-MID is +/-12dB). The signal will be unaffected when the controls are on center position. You may use an external equalizer to make up a mix properly but a master equalizer will not have effect on a single channel and you may overload the signal easily. Individual EQ will give you a much better control on single tracks.

5HI

If you turn this control up, you will boost all the frequencies above 12kHz (shelving filter). You will add transparency to vocals and guitar, and also make cymbals crispier. Turn the control down to cut all frequencies above 12 kHz. In such way, you can reduce sibilances of human voice or reducethehissofaTapeplayer.

This is a peaking filter and it will boost/cut frequencies with their center at 2.5kHz. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments.

7LOW

If you turn this control up, you will boost all frequencies below 80Hz. You will give more punch to bass drums and bass guitar; and you will make the male vocalist more"macho".Turnitdownandyouwillcutallthefrequenciesbelow80Hz.Inthis Way, you can avoid low-frequency vibrations and resonance thus preserving the life of your woofers.

8AUX

This control is used to adjust the level of respective channel signal sent to the Auxiliary Bus. The configuration is post-fader so the signal sent to the AUX Bus will be affected by the LEVEL control of that particular channel. In this typical compact unit, the channel signal is not only assigned to external effect or processor equipment directly but also to internal digital multi-effect.

There is the possibility to configure this AUX control as Pre-fader as we

microphone or an instrument to your AMX-100(FX) and sing/play at normal volume. Set the LEVEL control of that channel so that the PEAK LED lights-up only occasionally. If this LED is always on, you will experience a lot of distortion and you should turn the level control down. If this LED never light up, turn the level control up again.

11 LEVEL

This is the Master control for the channel signal. You must position the GAIN control correctly first (so that the PEAK LED only flashes occasionally) and the LEVEL control in between 0dB and 3 o'clock. If you have to turn up the level control too much, your GAIN control is probably set too low. If the level control is turned down too much, your GAIN is probably too high and your signal is heavily distorted.

5. QUICK START AND CONNECTIONS

OK. you have got to this point and you are now in the position to successfully operate your AMX-100(FX): However, we advise you to read carefully the following section to get the best out of your AMX-100(FX). 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. So you should follow these procedures before operation:

1. Before connecting microphones or instruments, make sure that the power of all your systems components including the AMX-100(FX) is turned off. Also, make sure that all input and output controls are turned down. This will avoid damage to your speakers and excessive noise.

2. Properly connect all external equipment such as microphone, power amplifier, speakers etc.

3. Now, turn on the power of any peripheral devices, then connect the 18VAC power supply to your AMX-100(FX) and to the AC socket.

NOTE: The power amplifier or powered monitors shall be turned ON after the

AMX-100(FX) and OFF before the AMX-100(FX) is turned OFF.

4. Set the output level of your AMX-100(FX) or the connected power amplifier at no more than 75%.

5.SettheCONTROLROOM/PHONElevelatnomorethan50%.

6.SetHI,MIDandLOWEQcontrolsoncenterposition.

7. Set panoramic (PAN / BAL) control on center position.

8. While speaking into the microphone (or playing the instrument) at normal volume, adjust the channel level control so that the input PEAK LED light-up only occasionally; in this way you will maintain good headroom and proper dynamic range.

9. You can shape the tone of each channel by adjusting the equalizer controls as desired.

10.Now repeat the same sequence for all input channels. The Main LED Meter could

move up into the red section. In this case you can adjust the overall output level through the MAIN MIX control..

PREFADER AND POSTFADER CONSIDERATIONS

Interesting consideration! Where are the faders in your AMX-100(FX)?? Actually a fader is usually regarded as a slider, that is a linear potentiometer. All potentiometers in your AMX-100(FX) are of rotary type but we keep the prefader / postfader description that

is quite industry standard and easily understandable. When your AMX-100(FX) leaves the Factory

LT O the AUX bus of all input channels is wired postfader. Inthisway,AUXbuscanbeusedfortheinternal or external multieffect. If you want to use the AMX-100(FX) AUX bus for powered stage monitors, you should disconnect the above-indicated POST route track and solder the PRE route track like in this drawing. In this way, the signal is routed to the AUX SENDS output before the Channel Level control.

Page 14

6. FOR THE EXPERTS WHO WANT TO KNOW MORE

As we have told you previously in this manual, the AUX SEND 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.
