Please observe the following items in any case:

The units are suitable for indoor use only. Pro- tect them against dripping water and splash water, high air humidity and heat (admissible ambient temperature range: 0 – 40 °C).

Do not place any vessel filled with liquid on the units, e. g. a drinking glass.

The heat generated inside the mixer must be dissipated by air circulation; never cover the air vents of the housing.

Do not operate the mixer and immediately dis- connect the power supply unit from the socket

1. if the mixer or the power supply unit is visi-

2. if a defect might have occurred after a unit

was dropped or suffered a similar accident,

3. if malfunctions occur.

In any case the units must be repaired by skilled personnel.

For cleaning only use a dry, soft cloth; never use water or chemicals.

No guarantee claims for the units and no lia- bility for any resulting personal damage or material damage will be accepted if the units are used for other purposes than originally intended, if they are not correctly connected or operated, or if they are not repaired in an expert way. 3 Applications This audio mixer is designed for universal PA and recording applications. It features 4 mono input channels and 4 stereo input channels to connect microphones (also phantom-powered) and audio sources with line output level (e. g. musical instruments, players). A send way allows for the use of an effect unit. However, effects can also be added via the integrated multi-effect processor (100 preset effects). Audio mixing can be monitored by means of headphones and / or a monitor system in a separate control room. In addition to connections for an analog recorder, the mixer features a USB audio inter- face to connect a computer. This interface can be used both as an output for digital recording of the audio mix and as an input to feed in audio files. If the units are to be put out of operation definitively, take them to a local recy- cling plant for a disposal which is not harmful to the environment. WARNING The power supply unit uses dan- gerous mains voltage. Leave ser - vicing to skilled personnel. Inex- pert handling or modification may result in electric shock.

GB4 Setting the Audio Mixer into Operation Prior to connecting / disconnecting and prior to switching on, always turn back the output con- trols BOOTH / PHONES (24) and MASTER (25) to the left stop.

4.1 Connecting audio sources

Since it is not possible to switch over 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.

Connect microphones to the balanced XLR jacks MIC (1). For phantom-powered micro- phones, press the button PHANTOM 48V (15) to activate a joint 48 V phantom power for all XLR jacks. When the phantom power has been acti- vated, the LED 48V (17) will light up.

4.1.2 Line audio sources

Connect audio sources with line signal level (e. g. receivers of wireless microphone systems, effect units, musical instruments, players) to the 6.3 mm jacks LINE (2) of the input channels. The jacks are balanced. However, to connect units with unbalanced output, use 2-pole 6.3 mm plugs. – Connect mono units to the mono channels CH 1 to CH 4. – Connect stereo units to the stereo channels CH 5 / 6 to CH 11 / 12. 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 no recorder is connected to the RCA input TAPE IN (18) [

able for an additional stereo unit with line level (e. g. a CD player for background music during intervals).

4.2 Connecting an effect unit

Via the send way, signal parts can be decoupled from the input channels, routed via an effect unit and then, after being processed, added to the sum signal. The signal will be picked up after the control LEVEL (10) of the corresponding input channel.

1) Connect the input of the effect unit via a

2) Connect the output of the effect unit to the

LINE input (2) of an input channel not used, refer to chapter 4.1.2.

4.3 Connecting a recorder

A stereo recorder, e. g. a tape recorder, can be connected to the RCA jacks TAPE IN (18) and TAPE OUT (19):

1) Connect the reproduction output of the re -

corder 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 adjusted with the control MASTER (25). The RCA jacks may also be used for other units with line signal level; it is, for example, possible to connect a reproduction unit such as a CD player or MP3 player to TAPE IN or an additional amplifier to TAPE OUT.

4.4 Connecting a monitor system

and headphones The audio mix, the input signal of the jacks TAPE IN (18) and of the USB port (33) or the effect way can be monitored via stereo headphones and / or a monitor system in a separate control room. Connect the headphones (minimum impedance 8 Ω) to the 6.3 mm jack PHONES (14). 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 (11) receives the sum signal adjusted with the control MAS- TER (25). At this output, the amplifier for PA applications can be connected (or another unit with line input, e. g. a second mixer). The 6.3 mm jacks are unbalanced.

Switching on and off Connect the power supply unit provided to the power supply jack (31) on the rear panel and to a mains socket (230 V~ / 50 Hz). To switch on the mixer, set the POWER switch (32) to ON; to switch it off, set the switch to OFF. When the mixer is switched on, the LED PWR ON (16) will light up. Note: Always disconnect the power supply unit from thesocket when the mixer is not in use for a longer periodof time; even when the mixer has been switched off, thepower supply unit will have a low power consumption.

4.7 Operation with a computer

Via the USB port (33), audio files can be trans- ferred in both directions between the mixer and the computer, even at the same time: – When the USB port is used as an input, data fed in via the USB port can be added to the sum signal and monitored via headphones/ monitor system in a control room. – When the USB port is used as an output, the USB port provides the sum signal adjusted with the control MASTER (25). To operate the mixer with a computer, either use the audio software supplied with the operating system or audio software installed additionally. Various audio software programs for recording and reproduction are available on the Internet free of charge.

1) Start the computer and connect the USB port

of the mixer to a USB connection on the com- puter.

2) The computer will recognize the switched-on

mixer as a USB audio device for audio input and audio output. The required drivers (de - fault drivers of the operating system) are available on the computer. Note: If not all drivers required are available on thecomputer, install them, e. g. by means of the originalCD of the operating system. If necessary, restart thecomputer after installing the drivers.

3) Call up the audio program used, make the

settings required 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 the system settings of the com- puter to find out if the USB interface has been selected for audio input or audio output. Hint: If the mixer is connected to both a computer andto units earthed via their mains cable (e. g. amplifiers),hum interference may occur due to ground loops. Toeliminate this interference, use a ground isolator (e. g.FGA-102 or FGA-202 from “img Stage Line”) to connectthe mixer to the corresponding unit. 5 Operation

5.1 Basic adjustments of the input

channels CH 1 to CH 11/12 The following steps for level matching and sound correction merely serve as an aid; other proce- dures are possible.

1) In all input channels, turn back the controls

LEVEL (10) and the controls AUX SEND (7) to the left stop. In the mono input channels, set all controls GAIN (3), all controls EQ (6) and all controls PAN (9) to mid-position and release all but- tons (4). In the stereo input channels, release all buttons +4/

10 (5) and set all controls BAL (9) to mid-position.

2) Release the buttons TAPE / USB TO MIX (21),

TAPE TO BOOTH / PHONES (22) and AUX SEND TO BOOTH (23).

3) Set the control MASTER (25) to mid-position.

4) Feed an audio signal to the corresponding

input channel (e. g. sing into a microphone, play a musical instrument).

5) To adjust a mono channel,

set the control LEVEL (10) to mid-position. Adjust the control GAIN (3) so that the LED level indicators (20) light up at 0 dB. Use the three EQ controls (6) to adjust the sound. If required, press the button (4) to suppress low-frequency interference (e. g. impact noise, hum). Then, if necessary, use the control GAIN to correct the level adjustment. The LED PEAK (8) should briefly flash for signal peaks only. If it lights permanently, turn back the control GAIN and / or the equalizer con- trols accordingly. To adjust a stereo channel, turn up the control LEVEL (10) so that the LED level indicators (20) light up at 0 dB. If you have to turn up the control considerably, press the button +4/

10 (5) to boost the level (12 dB) for the channel. If you have to turn back the control considerably and the LED PEAK (8) of the channel lights permanently, attenuate the output level of the audio source.

6) After adjusting a channel, turn back its control

LEVEL to the left stop, and then adjust the next channel. 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 get- ting used to it. Caution: When the phantom power has been activated, do not connect any microphone with unbalanced output; it may be damaged. To prevent switching noise in the speakers and the headphones, only activate or deactivate the phantom power when the mixer has been switched off or when the corresponding output controls have been turned back to the left stop.

GB5.2 Mixing audio sources

1) Turn up the control MASTER (25) 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

(10) to mix the signals of the input channels in the volume ratio desired. Always turn back the controls LEVEL of the channels not used to the left stop.

3) For the mono channels, use the panorama

controls PAN (9) to place the mono signals in the stereo sound. For the stereo channels, use the controls BAL (9) to adjust the balance of the stereo signals.

4) To add effects, refer to the following chap-

5) To add the input signal of the jacks TAPE IN

(18) and of the USB port (33) to the signal sum, press the button TAPE / USB TO MIX (21). Note: If, during recording via the jacks TAPE OUTor the USB port, the recording signal is sent as aninput signal to the jacks TAPE IN or to the USB port,make sure that the button TAPE / USB TO MIX is notpressed; otherwise, there will be feedback.

6) Use the control MASTER (25) to adjust the

definitive volume of the sum signal; check the LED level indicators (20) while adjusting the volume. Make sure that none of the two but- tons (22, 23) for the monitor function is pressed; otherwise, the LED level indicators will not indicate the level of the sum signal. In case of overload, the red LEDs CLIP of the level indicators will light up.

Connect the effect unit to the output AUX SEND (13) and to the LINE input (2) of an input channel not used.

1) To make sure that the subsequent effect

adjustments are audible, first set the control LEVEL (10) of the channel to which the effect unit has been connected approximately to mid-position.

2) Use the controls AUX SEND (7) to add the

signals of the input channels to the effect way. The signal will be picked up after the control LEVEL (10), i.e. the effect part of a channel is always proportional to the channel level adjusted. The sum of all signals added to the effect way is sent to the effect unit via the output AUX SEND (13). Note: Turn back the control AUX SEND of the chan-nel to which the effect unit has been connected tothe left stop; otherwise, there will be feedback.

3) Use the control LEVEL (10) of the channel to

which the effect unit has been connected to add the output signal of the effect unit to the sum signal.

5.3.2 Using the internal effect processor

1) To make sure that the subsequent effect

adjustments are audible, first set the control FX TO MASTER (30) approximately to mid- position.

2) Turn the selector knob FX SELECT (26) back

and forth until the number of the desired effect (

effect overview below) starts flash- ing on the display (27). Press the knob briefly to confirm. The number will stop flashing when the effect has been adjusted.

3) Use the controls AUX SEND (7) to add the

signals of the input channels to the effect way. The signal will be picked up after the control LEVEL (10), i. e. the effect part of a channel is always proportional to the channel level adjusted. The sum of all signals added to the effect way is sent to the input of the effect processor.

4) Use the control FX TO MASTER (30) to add

the output signal of the effect processor to the signal sum. The LED PEAK / MUTE (29) will light up if there is an overload at the input of the effect processor. Turn back any controls AUX SEND (7) turned up too far. If necessary, turn up the control FX TO MASTER in compensa- tion.

5) To mute the effect processor, press the but-

ton MUTE (28) [button will not engage]. When the muting feature has been activated, the LED PEAK / MUTE (29) will light up. To unmute, press the button MUTE once again; the LED PEAK / MUTE will be extinguished. Note: If the mixer is switched off while the effectprocessor is muted, the muting feature will be deac-tivated when the mixer is switched on again.

5.4 Monitoring via headphones and

• monitor system The two assign buttons (22, 23) for the monitor function define which signal will be monitored via the outputs BOOTH OUT (12) and PHONES (14) and indicated by the LED level indicators (20): – If none of the buttons is pressed, the sum sig- nal adjusted with the control MASTER (25) will be monitored and indicated. – If only the button TAPE TO BOOTH / PHONES (22) is pressed, the input signal of the jacks TAPE IN (18) and of the USB port (33) will be monitored and indicated (e. g. to check a recording). – If the button AUX SEND TO BOOTH (23) is pressed, the signal of the effect way will be monitored and indicated. In this case, the position of the button TAPE TO BOOTH / PHONES is irrelevant. Use the control BOOTH / PHONES (24) to adjust the monitoring volume. 6 Specifications Input sensitivity Mic: p. 0
