3 Applications

This audio mixer is designed for universal PA and recording applications. It provides two mono and two stereo input channels to connect microphones (also phantom-powered) and audio sources with line output levels (e.g. musical instruments and reproduction units). A send way allows for the use of an effect unit. In addition, connections for a recorder are available. Audio mixing may be monitored by means of headphones and/or a monitor system in a separate control room.

The model MMX-22UFX additionally provides an internal effect processor (16 predefined effects and/or one reverberation effect may be selected) and a USB audio interface for connection to a computer.

GB 4 Setting the Audio Mixer into Operation

Prior to connecting/disconnecting and prior to each switch-on, the output controls BOOTH/0 (23) and MASTER (24) should be turned back to the left stop.

4.1 Connecting audio sources

Since it is not possible to switch between the inputs in the mono channels, either use the microphone input (1) or the line input (2); never use both inputs at the same time.

4.1.1 Microphones

Connect microphones to the balanced XLR jacks MIC (1) of the channels CH 1 and CH 2. For phantom-powered microphones, press the button PHANTOM 48 V (21) to activate a joint phantom power supply of 48 V for the two XLR jacks. When the phantom power supply is activated, the phantom power supply indicator (20) lights up.

Caution: When the phantom power is activated, no microphones with unbalanced output must be connected, as they could be damaged.

To prevent switching noises in the speakers and the headphones, only switch the phantom power on or off when the mixer is switched off or when the corresponding output controls have been turned back to their left stop.

4.1.2 Line audio sources

Connect audio sources with line signal level (e.g. receivers of wireless microphone systems, musical instruments, reproduction units) to the 6.3 mm jacks (2) of the input channels. The jacks are balanced. However, it is also possible to connect units with unbalanced output via 2-pole 6.3 mm plugs.

• Connect mono units to the channels CH 1 and CH 2.
• Connect stereo units to the channels CH 3/4 and CH 5/6. To connect a mono unit to a stereo channel, only use the jack L; the mono signal will then internally be sent to the right and the left channels.

If the input channels do not suffice, use the following stereo inputs to connect additional line sources:

- unbalanced 6.3 mm jacks STEREO AUX RE TURN (9)

- RCA jacks TAPE IN (14)

Notes with regard to the Input STEREO AUX RETURN

1. To connect a mono unit to the input STEREO AUX RETURN of the model MMX-22, only use the jack L; the mono signal will then internally be sent to the right and left channels. For the model MMX-22UFX, use a Y cable to connect a mono unit to both jacks.
2. For model MMX-22UFX: connecting a unit to the two jacks STEREO AUX RETURN will mute the left and right output respectively of the internal effect processor.

4.2 Connecting an effect unit

Using the send way, signal parts can be decoupled from the input channels, transmitted via an effect unit and then, after being processed, added to the sum signal. The signal is picked up after the control LEVEL (8) of the corresponding input channel.

Connect the effect unit via the unbalanced 6.3 mm jacks AUX SEND (10) and STEREO AUX RE TURN (9):

1) Connect the input of the effect unit to the mono output AUX SEND.
2) Connect the output of the effect unit to the stereo input STEREO AUX RETURN. Please also observe the notes with regard to the input in chapter 4.1.2.

4.3 Connecting a recorder

A stereo recorder, e. g. a tape recorder, may be connected to the RCA jacks TAPE IN (14) and TAPE OUT (15):

1) Connect the reproduction output of the recorder to the input TAPE IN.
2) Connect the recording input of the recorder to the output TAPE OUT; the output will receive the sum signal that has been adjusted by means of the control MASTER (24).

The RCA jacks may also be used for other units with line signal levels; it is, for example, possible to connect a reproduction unit such as a CD player or MP3 player to TAPE IN or to connect an additional amplifier to TAPE OUT.

4.4 Connecting a monitor system and headphones

Using stereo headphones and/or a monitor system in a separate control room, audio mixing or the input signal of the jacks TAPE IN (14) and of the USB jack (C)* can be monitored. Connect the headphones (minimum impedance of 8 Ω) to the 6.3 mm jack PHONES (11). Connect the amplifier of the monitor system to the stereo output BOOTH OUT (12); the two 6.3 mm jacks of the output are unbalanced.

4.5 Connecting an amplifier

The stereo output MASTER OUT (13) receives the sum signal that has been adjusted by means of the control MASTER (24). Here, the amplifier for PA applications can be connected (or another unit with a line input, e.g. a second mixer). The 6.3 mm jacks are unbalanced.

4.6 Power supply Switching on and off

Connect the power supply unit provided to the power supply jack (A) on the rear panel and to a mains socket (230 V\~/ 50 Hz).

To switch on the mixer, set the switch POWER (B) to ON; to switch it off, set the switch to OFF. When the mixer is switched on, the LED POWER ON (18) lights up.

Note: If the mixer is not to be used for a longer period of time, disconnect the power supply unit from the socket, because it will consume some power even when the mixer is switched off.

4.7 Operation with a computer\*

Using the USB jack (C), audio files can be transferred in both directions between the mixer and the computer, even at the same time:

• Using the USB jack as an input: Data fed in via the USB jack can be added to the sum signal and can be monitored by means of headphones/a control room monitor system.
• Using the USB jack as an output: The USB jack provides the sum signal that has been adjusted by means of the control MASTER (24).

To operate the mixer with a computer, the audio software supplied with the operating system or additionally installed audio software may be used. Various audio software programs for recording and reproduction are available on the Internet free of charge.

1) Start the computer and connect the USB jack of the mixer to a USB connection on the computer.
1) Start the computer and connect the USB jack of the mixer to a USB connection on the computer.
2) The computer will recognize the switched-on mixer as a USB audio device for audio input and audio output. The required drivers (default drivers of the operating system) are available on the computer.
Note: If not all required drivers are available on the computer, they must be installed, e. g. by means of the original CD of the operating system. If necessary, restart the computer after you have installed the drivers.
3) Call up the audio program to be used; there, make the appropriate settings for audio reproduction via the mixer or audio recording from the mixer ( manual of the program). The mixer can then be operated as described in chapter 5.

If no audio recording or audio reproduction is possible, check in the system settings of the computer if the USB interface has been selected for audio input or audio output.

Hint: If the mixer is connected to both a computer and to units that are earthed via their mains cable (e. g. amplifiers), hum interference may occur due to ground loops. To eliminate the hum interference, the mixer may be connected to the respective unit by means of a ground isolator (e. g. FGA-102 or FGA-202 from "img Stage Line").

5 Operation

CAUTION

Never adjust the audio system and the headphones to a very high volume. Permanent high volumes may damage your hearing! Your ear will get accustomed to high volumes which do not seem to be that high any more after some time. Therefore, do not further increase a high volume after getting used to it.

5.1 Basic adjustments of the input channels CH 1 to CH 5/6

The following steps for level matching and sound correction merely serve as an aid; other procedures are possible.

1) In the input channels:
- turn back all controls LEVEL (8) and all controls AUX SEND (5) to the left stop
- turn all controls GAIN (3), all sound controls (4) and all controls PAN and BAL (6) to their mid-position
2) Model MMX22-UFX: turn back the control AUX RETURN (19) to the left stop
3) If pressed, disengage the two buttons TAPE[/USB*] TO BOOTH/PHONES (16) and TAPE[/USB*] TO MIX (17).
4) Turn the control MASTER (24) to its mid-position.
5) Feed an audio signal to the respective first input channel (e. g. sing into a microphone, play a musical instrument).
6) To adjust a mono channel turn the control LEVEL (8) to its mid-position. Adjust the control GAIN (3) so that the LED level indicator (22) lights up at 0 dB. Use the three EQ controls (4) to adjust the sound.

Then, if necessary, use the control GAIN to correct the level adjustment. The LED indicator PEAK (7) should briefly flash for signal peaks only. If it lights up permanently, turn back the control GAIN and/or the sound controls correspondingly.

To adjust a stereo channel

turn the control LEVEL (8) so that the LED level indicator (22) lights up at 0 dB, and then use the EQ controls (4) to optimize the sound. If the LED indicator PEAK (7) lights up permanently, turn back the appropriate sound controls correspondingly or reduce the output level of the audio source.

7) After adjusting a channel, turn back its control LEVEL to the left stop and then adjust the next channel.

5.2 Mixing audio sources

1) Turn up the control MASTER (24) so that the mixing ratio of the audio sources can be adjusted in an optimum way.
2) When all level matching adjustments and all sound adjustments have been made ( chapter 5.1), use the controls LEVEL (8) to mix the signals of the input channels CH 1 to CH 5/6 in the volume ratio desired. Always turn the controls LEVEL of the channels not used back to the left stop.
3) For the mono channels, use the panorama controls PAN (6) to place the mono signals in the stereo sound. For the stereo channels, use the controls BAL (6) to adjust the balance of the stereo signals.
4) For adding effects, please refer to chapter 5.3.
5) If an additional audio source is connected to the input STEREO AUX RETURN (9): for the model MMX-22UFX, use the control AUX RETURN (19) to add the signal of the additional audio source to the signal sum. (Model MMX-22 does not provide a level control for the input.)
6) To add the input signal of the jacks TAPE IN (14) and of the USB jack (C)* to the signal sum, press the button TAPE[/USB*] TO MIX (17).

Note: If, during recording via the jacks TAPE OUT or the USB jack*, the recording signal is sent as an input signal to the jacks TAPE IN or the USB jack*, the button TAPE[/USB*] TO MIX may not be pressed; otherwise, there will be a feedback.

7) Use the control MASTER (24) to adjust the definite volume of the sum signal; check the LED level indicator (22) while adjusting the volume. Make sure that the button TAPE[/USB*] TO BOOTH/PHONES (16) is not pressed; otherwise, the LED level indicator will not indicate the level of the sum signal. The red LEDs CLIP of the level indicator will light up to indicate an overload.

5.3 Adding effects

5.3.1 Using an external effect unit

1) To make sure that the subsequent effect adjustments are audible, first adjust the control AUX SEND MASTER (19) [model MMX-22] or AUX RETURN (19) [model MMX-22UFX] approx. to its mid-position.

2) Use the controls AUX SEND (5) to add the signals of the channels CH 1 to CH 5/6 to the effect way. The signal is picked up after the control LEVEL (8), i. e. the effect part of a channel is always proportionate to the channel level adjusted.

3) Model MMX-22:

Use the control AUX SEND MASTER (19) to adjust the level for the sum of all signals that were added to the effect way. The sum signal of the effect way is sent to the effect unit via the output AUX SEND (10). The signal from the effect unit is added to the signal sum via the jacks STEREO AUX RETURN (9).

Model MMX-22UFX:

The sum of all signals added to the effect way is sent to the effect unit via the output AUX SEND (10). Use the control AUX RETURN (19) to add the signal received from the effect unit at the input STEREO AUX RETURN (9) to the sum signal.

5.3.2 Using the internal effect processor\*

The input STEREO AUX RETURN (9) must be available (note 2 in chapter 4.1.2).

1) To make sure that the subsequent effect adjustments are audible, first turn the control AUX RETURN (19) and the appropriate effect control (26) – FX LEVEL for effects 1 to 16, REVERB for the reverberation effect – approx. to their mid-positions.
2) Use the controls AUX SEND (5) to add the signals of the channels CH 1 to CH 5/6 to the effect way. The signal is picked up after the control LEVEL (8), i. e. the effect part of a channel is always proportionate to the channel level adjusted.
3) Use the switch FX SELECT (25) to select the desired effect from a choice of 16 predefined effects. Use the controls FX LEVEL and REVERB LEVEL (26) to adjust the level for the appropriate effect signal as desired:

- FX LEVEL for effect 1 - 16

- REVERB LEVEL for the reverberation effect

4) Use the control AUX RETURN (19) to add the output signal of the effect processor to the signal sum.

If the LED PEAK (27) lights up, the input of the effect processor is overloaded. Turn back the appropriate controls AUX SEND (5) correspondingly and, if necessary, compensate this by advancing the control AUX RETURN (19).

5.4 Monitoring via headphones and monitor system

The button TAPE[/USB*] TO BOOTH/PHONES (16) determines the signal to be monitored via the outputs PHONES (11) and BOOTH OUT (12) and to be indicated by the LED level indicator (22):

• When the button is not pressed, the sum signal adjusted by means of the control MASTER (24) is monitored and indicated.
• When the button is pressed, the input signal at the jacks TAPE IN (14) and at the USB jack (C)* is monitored and indicated (e. g. for checking a recording).

Use the control BOOTH/ (23) to adjust the monitoring volume.
