It provides 8 mono and 2 stereo input channels to connect microphones (also phantom-powered) and audio sources with line output level (e. g. instruments and players). The input signals can be added to a stereo sum channel, two subgroups and two send ways. The integrated effect processor can be used to add effects. Audio mixing may be monitored by means of headphones and / or a monitor system in a separate control room. In addition to the RCA jacks for a recorder, the mixer provides a USB audio interface for connection to a computer. This interface may be used as an output for digital recording of the audio mix and as an input for feeding in audio files. If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harmful to the environment. WARNING This unit uses dangerous mains voltage. Leave servicing to skilled personnel. Do not insert anything into the air vents. Inexpert han- dling or modification may result in electric shock.

GB4 Connecting Units To avoid interfering noise, switch off the mixer or turn back /set the following controls / faders to minimum prior to connecting / disconnecting: – MASTER (34) – BOOTH / PHONES (33) – AUX SEND MASTER 1 / MON (30) if send way 1 is used as a monitor way.

Since it is not possible to switch between the inputs in the mono channels, either connect the microphone input (22) or the line input (21); never connect both inputs at the same time.

Connect microphones to the balanced XLR jacks MIC (22). For phantom-powered microphones, use the switch PHANTOM (49) on the rear panel to activate a joint phantom power supply of 48 V for all XLR jacks. When the phantom power sup- ply is activated, the LED PHANTOM 48V (35) lights 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 (21) 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 8. — Connect stereo units to the stereo channels CH 9 /10 and 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 left channels. If the input channels do not suffice, use the fol- lowing stereo inputs to connect additional line sources:

1. input AUX RTN (56)

(To connect a mono unit, only use the jack L; the mono signal will then internally be sent to the right and left channels.)

2. input FX RTN (57)

(When the input is connected, the signal way from the internal effect processor to the sum channels will be interrupted.)

3. input TAPE IN (23)

(e. g. to connect a CD player for background music during intervals)

Effect units (e. g. units for audio processing such as compressors, equalizers and noise gates) may be directly inserted into the mono channels: The channel signal is decoupled after the control GAIN (20) and the low cut filter (18), is routed via the effect unit and is then returned to the chan- nel at the same position in the signal way. Connect the effect unit to the 6.3 mm jack CHANNEL INSERT (58) of the respective chan- nel. The plugs must be connected as follows: tip = Send (output) ring = Return (input) sleeve = Ground To connect effect units with separate input and output jacks, Y cables are required, e. g. MCA- 202 from MONACOR: Fig. 6 Connection via Y cable MCA-202

4.2.2 Using send ways

Via send ways 1 and 2, signal parts can be decoupled from the input channels, processed by means of an effect unit (e. g. reverb unit) and returned to the mixer via the Return inputs. Nor- mally, the signal for a send way used as an effect way is picked up post-fader, i. e. the channel sig- nal is added to the send way after the fader (1). Thus, the effect part of a channel is always in proportion to the channel level adjusted. For each channel, the button PRE (10) can be pressed to switch send way 1 from post-fader to pre-fader. Send way 2 is preset to post-fader; this cannot be changed. Send way 2 also serves as an effect way for the internal effect processor.

2) To return the signal coming from the effect

unit, the inputs AUX RTN (56) and FX RTN (57) are available: — When the input AUX RTN is used: Use the control AUX RTN (31) to add the effect signal to either the sum channels MAS- TER [button MASTER / SUB 1-2 (39) dis- engaged] or to the subgroup channels [button MASTER / SUB 1-2 pressed]. Note: To connect a mono unit, only use the jackL; the mono signal will then internally be sent tothe right and left channels. — When the input FX RTN is used: Use the control FX RTN (27) to add the effect sig- nal to the sum channels or use the control RETURN TO AUX 1 (37) to add the effect signal to send way 1. Note: Connecting the jack L and R of this inputwill interrupt the signal way from the left andright channels of the internal effect processor tothe sum channels. Alternatively, feed the signals from the effect unit to the line input of an available input channel.

A recorder can be connected to the RCA jacks TAPE (23) [L = left channel, R = right channel]:

1) For reproduction, connect the output of the

unit to the jacks TAPE IN.

2) For recording, connect the input of the unit to

the jacks TAPE OUT. Here, the sum signal adjusted by means of the faders MASTER (34) is available.

4.4 Connecting a control monitor

system and headphones The signals of the individual input channels, the sum signals, the subgroup signals and the input signals of the jacks TAPE IN (23) and of the USB port (45) can be monitored via headphones and/ or a monitor system in a separate control room. Connect the headphones (minimum impedance: 8 Ω) to the jack PHONES (52). Connect the amplifier of the monitor system to the jacks BOOTH OUT (53); these output jacks are unbal- anced.

4.5 Monitor system for the musicians

When a monitor system is used for stage PA applications, send way 1 may serve as a monitor way. Normally, the signal for the send way used as a monitor way is picked up pre-fader, i. e. the channel signal is added to the send way ahead of he fader (1). Thus, the stage monitors provide the musicians with an audio signal that has been separately mixed. For each input channel, the buttons PRE (10) can be pressed to switch send way 1 to pre-fader. Connect the amplifier of the monitor system or of an active monitor speaker system to the mono output jack AUX SEND 1 (55).

4.6 Amplifier for PA applications

in halls The stereo sum signal is available at the outputs MASTER (50): XLR jacks, balanced

6.3 mm jacks, unbalanced

(L= left channel, R = right channel). Connect the amplifier for PA applications in halls to one of the outputs. The second output may be used at the same time, e. g. for a second ampli- fier or to send the sum signal to an additional unit.

4.7 Operation with a computer

Via the USB port (45), audio files can be trans- ferred in both directions between the mixer and the computer: — When the USB port is used as an input: Use the button TAPE / USB TO MIX (41) to add data fed in via the USB port to the sum signal and to monitor the data via headphones and a control monitor system. — When the USB port is used as an output: The USB port provides the sum signal that has been adjusted with the faders MASTER (34). 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

(45) 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 (de - fault drivers of the operating system) should be 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. Caution: When the phantom power is acti- vated, 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 con- trols have been set to minimum.

GBIf no audio recording or audio production is pos- sible, check the system settings of the computer 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.

4.8 Outputs of the subgroups

The subgroup signals can be added to the signal sum via the buttons SUB ASSIGN TO MASTER (26), but they are also available at the outputs SUB OUT (54). The subgroup signals may be forwarded from these outputs to another mixer or to a separate effect unit, for example.

4.9 Foot pedal for the effect processor

To activate and deactivate the internal effect processor, a foot pedal, e. g. FS-60 from MONA- COR, may be connected to the 2-pole 6.3 mm jack FOOT SWITCH (51).

5.1 Switching on and off

1) To prevent switching noise and an excessive

volume, set the following output controls to minimum prior to switching on the mixer: — MASTER (34) — BOOTH / PHONES (33) — AUX SEND MASTER / MON (30) if send way 1 is used as a monitor way.

2) Depending on the microphone type con-

mixer on and off. When the mixer is switched on, the LED indicator POWER ON (36) will light up.

5.2 Level control of the input

channels The following steps merely serve as an aid; other procedures are possible.

1) First, make the following basic adjustments:

a) In all mono input channels (fig. 1), set the controls GAIN (20), the equalizer controls HIGH (17), MID (13), LOW (12) and the control PAN (7) to mid-position. Disen- gage the buttons (18). b) In all stereo input channels (fig. 2), set the equalizer controls HIGH (17), MID 3 kHz (16), MID 500 Hz (14), LOW (12) and the control BAL (8) to mid-position. Disen- gage the button +4 /

10 (19) in channel CH 9 /10, and disengage the button LINE / OPT (19) in channel CH 11/12. c) In all input channels, turn back the con- trols AUX SEND 1 / MON (11) and AUX SEND 2 / FX (9) for the send ways to min- imum. d) In all input channels, disengage the but- tons MUTE (6), 1-2 (4), L-R (3) and SOLO (2) and set the channel faders (1) to mini- mum. e) On the output panel (fig. 3), disengage all buttons SOLO (29) and the button TAPE/ USB TO MIX (41) and turn back the con- trols AUX SEND MASTER (28, 30) and the controls RETURN (27, 31, 37) to min- imum.

2) Feed an audio signal to the first channel used

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

3) If the signal is to be made audible via the con-

nected amplifier for PA applications in halls, advance the fader (1) of the channel to the position “0”, press the button L-R (3) and then advance the faders MASTER (34) until the signal can be heard well. However, it is also possible to monitor the signal via head- phones or a control monitor system when the faders are closed,

4) Press the button SOLO (2) of the channel to

switch on the monitor function for the chan- nel; the LED PEAK (5) will light up.

5) If necessary, disengage the button PFL /AFL

(40) to select the monitor mode “PFL”: the LED beneath the button will light up in green and the left row of LEDs of the level indicators (38) will indicate the channel signal ahead of the fader and the control PAN (7) or BAL (8).

6) Use the level indicators for an optimum

adjustment of the input amplification: For a mono channel, adjust the control GAIN (20) so that a level of approximately 0 dB is indicated. If the stereo channel CH 9 /10 is over- loaded even though the button +4 /

10 (19) is disengaged, attenuate the level of the signal source. If the level is too low, press the button +4 /

10 to boost the level (12 dB). The input amplification for the stereo chan- nel CH 11/12 is predefined and cannot be changed. If the level is not ideal, change the output level of the signal source connected.

7) Adjust the sound, using the controls HIGH

(17) for the high frequencies and LOW (12) for the low frequencies (±15 dB). For a mono channel, use the control MID FREQ (15) to adjust the mid-frequency (100 – 8000 Hz), and use the control MID (13) to boost or attenuate (15 dB) it. If required, press the button (18) to suppress low- frequency interference (e. g. impact noise, hum). For a stereo channel, use the controls MID 500 Hz (14) and MID 3 kHz (16) to adjust the mid-frequencies (±15 dB). Then check the level of the channel and, if necessary, correct the input amplification.

8) Disengage the button SOLO to switch off the

monitor function for the channel. When the monitor function is switched off, the LED PEAK serves as an overload indicator with which the level of the channel can be roughly checked. If it lights permanently, attenuate the input amplification (control GAIN) or the input signal.

9) To make sure that only the channel being

adjusted is audible while the signal is being reproduced via the amplifier for PA applica- tions in halls: After controlling the level of a channel, set its fader (1) to minimum or press MUTE (6) to mute the channel.

5.3 Mixing input signals

1) Define for each input channel if the channel

signals are to be added to the sum channels or/ and to the subgroup channels: — To add the signals to the sum channels MASTER, press the button L-R (3). — To add the signals to the channels SUB 1 and 2, press the button 1-2 (4). Use the faders SUB 1 and 2 (24) to fade in and fade out these signals or to change their volume. If required, use the jacks SUB OUT (53) to send these signals to a sepa- rate effect unit.

2) Advance the faders MASTER (34) until it is

possible to adjust the mixing ratio of the audio sources in an optimum way.

3) Use the faders (1) to mix the signals of the

input channels in the volume ratio desired. Always close the faders of unused channels.

4) For the mono channels, use the panorama

controls PAN (7) to place the mono signals in the stereo sound. For the stereo channels, use the controls BAL (8) to adjust the balance of the stereo signals.

5) If signals are sent to the subgroups, press the

corresponding buttons SUB ASSIGN TO MASTER (26) to add the subgroups to the left and right sum channels. (Usually, press the button L in channel SUB 1 and the button R in channel SUB 2). Use the faders SUB 1 and SUB 2 (24) to adjust the volume of the sub- group signals.

6) Please refer to chapter 5.5 for information on

To add the input signal of the jacks TAPE IN (23) and of the USB port (45) to the signal sum, press the button TAPE / USB TO MIX (41). Note: If, during recording via the jacks TAPE OUTor the USB port, the recording signal is fed 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.

8) Use the faders MASTER to adjust the definite

volume of the sum signal; check the level indicators (38) while adjusting the volume. To make sure that the level indicators indicate the level of the sum signal, press the button MASTER MIX (32). Also make sure that all the buttons SOLO (2, 29) for the monitor function are disengaged. [If one of the but- tons SOLO is pressed, the LED beneath the button PFL /AFL (40) will light up.] The red LEDs CLIP of the level indicator will light up in case of overload; close the faders MAS- TER accordingly.

9) To mute a channel, e. g. during an interval,

press the button MUTE (6, 25). The LED beneath the button will light up.

5.4 Adjusting the monitor send way

Make sure that the monitor system for stage PA applications is connected to the jack AUX SEND 1 (55) of send way 1.

1) For the channels that are fed to the monitor

way, press the button PRE (10) in order to set the position where the signal for the monitor way is picked up to pre-fader.

2) Turn up the control AUX SEND MASTER 1 /

MON (30) for the total volume of the monitor mix until the monitor signal can be easily 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.

GBheard via the monitor system when the sub- sequent adjustments are made.

3) Use the controls AUX SEND 1 / MON (11) to

add the channel signals to the monitor way: Turn up the controls, depending on the de - sired volume ratio of the channels.

4) Use the control RETURN TO AUX 1 (37) to

add the effect signal of the internal effect processor to monitor way 1 or to add the sig- nal from the jacks FX RTN (57) if a unit is con- nected to these jacks.

5) To monitor the monitor way via headphones

or a control monitor system and to have the monitor signal indicated by the level indica- tors (38), press the button SOLO (29) next to the control AUX SEND MASTER 1 / MON (30),

The internal effect processor allows for the gen- eration of 100 different effects that can be added to the sum channels MASTER and to send way 1. Send way 2 is used as an effect way for the effect processor. Important: The input FX RTN (57) must be available when the effect processor is used. When the two jacks are connected, the signal way of the internal effect processor to the sum channels and to send way 1 is interrupted.

1) To make sure that the subsequent effect

adjustments are audible, first set the controls AUX SEND MASTER 2 / FX (28) and FX RE - TURN (27) approximately to mid-position.

2) Turn the knob FX SELECT (43) clockwise or

counter-clockwise until the number of the desired effect (

figure 7 Effect overview) starts flashing on the display (44). Press the knob to confirm the number: The number stops flashing; the effect is activated.

3) Use the controls AUX SEND 2 / FX (9) to add

the signals of the input channels to the effect way. The signal is picked up after the fader (1), i. e. the effect part of a channel is always in proportion to the channel level adjusted.

4) Use the control AUX SEND MASTER 2 / FX

(28) to adjust the level of all the signals that have been added to the effect way. The sig- nals are fed to the input of the effect proces- sor and are also available at the jack AUX SEND 2 (55). When the effect processor is activated, the LED PEAK above the button MUTE (42) serves as an overload indicator with which the level can be roughly checked. If the LED PEAK lights up, turn back the control AUX SEND MASTER 2 / FX accordingly.

5) Use the button FX RETURN (27) to add the

effect signal to the sum channels, and if desired, use the button RETURN TO AUX 1 (37) to add the effect signal to send way 1.

6) Use a foot pedal connected to the jack FOOT

SWITCH (51) and the button MUTE (42) to switch the effect processor off and on (the button will not engage). When the effect processor is switched off, the LED PEAK above the button MUTE will light up.

5.5.2 External effect unit

The effect unit must be connected via an Aux Send output and an Aux Return input (or line input of an available input channel),

1) To make sure that the subsequent effect ad -

justments are audible, set the respective out- put control and input control approximately to mid-position: depending on the output used control AUX SEND MASTER 1 / MON (30)

2) If the effect unit is connected to the input AUX

RTN (56), use the button MASTER / SUB 1-2 (39) to define if the effect signal is to be sent to the sum channels (button disengaged) or to the subgroup channels (button pressed).

3) Depending on the send way used as an effect

way, use the controls AUX SEND 1 / MON (11) or the controls AUX SEND 2 / FX (9) to add the channel signals to the effect way. With these controls, the desired effect intensity can be separately adjusted for each channel. If send way 1 is used as an effect way, the buttons PRE (10) must be disengaged (set- ting post-fader). Note: If the effect unit is connected to the line input of an input channel, turn back the control AUX SEND 1 or 2 of the respective channel to minimum; otherwise, there will be feedback.

4) Use the appropriate output controls AUX

SEND (28, 30) to adjust the level for the out- put signal of the effect way so that the effect unit is not overloaded. Use the button SOLO (29) next to the con- trol AUX SEND to monitor the effect way via headphones or a control monitor system and to check it by means of the level indicators (38),

signal coming from the effect unit; the control allows for the joint adjustment of the effect intensity for all channels: — If the effect unit is connected to the input AUX RETURN (56), use the control AUX RTN (31) to add the effect signal to the sum channels or to the subgroup channels (depending on the position of the button MASTER / SUB1-2). — If the effect unit is connected to the input FX RTN (57), use the control FX RETURN (27) to add the effect signal to the sum channels. The control RETURN TO AUX 1 (37) can be used to add the effect signal to send way 1 as well (e. g. if it is used as a monitor way). — If the effect unit is connected to the line input (21) of an input channel, use the appropriate channel fader (1) to add the effect signal to the sum channels [the button L-R (3) must be pressed] and/ or to the subgroup channels [the button 1-2 (4) must be pressed].

5.5.3 Separate effect unit for the subgroups

Independently of the options described in chap- ters 5.5.1 and 5.5.2, the signals of the subgroups can be routed via a separate effect unit.

1) Connect the input of the effect unit to the

jacks SUB OUT (54) and connect the output of the effect unit to an available line input of the mixer.

2) Use the buttons ASSIGN TO MASTER (26)

to select one of the following options: — To route the signals of the subgroups entirely via the effect unit and to add them to the sum channels from there, disen- gage all buttons. — To add the signals of the subgroups to the sum channels in the mixer and to add the effect signals of the subgroups to the sum channels, press the appropriate buttons (usually, the button L in channel SUB 1 and the button R in channel SUB 2).

3) Use the faders SUB 1 and 2 (24) to adjust the

level with which the signals of the subgroups are fed to the effect unit and, if applicable, to the sum channels.

4) Make all the other adjustments at the effect

unit and at the input channel to which the effect unit is connected.

1. the signal of each input channel

2. the total signals of send ways 1 and 2

3. the input signals of the jacks TAPE IN (23)

and of the USB port (45)

4. the signals of subgroups 1 and 2 at the out-

5. the sum signals of the mixer at the outputs

MASTER (50) The level indicators (38) always indicate the level of the signals that have been selected for monitoring.

1) To monitor an input channel, press the but-

ton SOLO (2) of the channel. The LED PEAK (5) lights up to indicate that the monitor func- tion for the channel has been activated. Addi- tionally, the LED beneath the button PFL/AFL (40) lights up: green for the monitor mode “PFL” or red for the mode “AFL”. — When the button PFL/ AFL is disengaged, the mode “PFL” (pre-fader listening) is ac - tivated. This mode can be used to adjust the level of a channel: The channel signal is monitored and indicated (mono) ahead of the fader (1) and the panorama control (7) or balance control (8). — When the button PFL /AFL is pressed, the mode “AFL” (after-fader listening) is acti- vated with which the overall channel adjustment can be checked: The channel signal is monitored and indicated (stereo) after the fader and the panorama control or balance control.

2) To monitor a send way, press the corre-

sponding button SOLO (29): for send way 1, the button SOLO next to the control AUX SEND MASTER 1 (30), for send way 2, the button SOLO next to the control AUX SEND MASTER 2 (28). Use the button PFL /AFL to select the monitor mode: When the button is disengaged, the signal will be monitored and indicated ahead of the control AUX SEND MASTER; when the button is pressed, the signal will be monitored and indicated after the control AUX SEND MASTER.

3) To monitor the input signal of the jacks

TAPE IN (23) und of the USB port (45), e. g. to check a recording, press the button CD/ USB / TAPE (32).

4) To monitor the subgroup signals (always

post-fader), press the button SUB 1-2 (32).

5) To monitor of the sum signals (always post-

fader), press the button MASTER MIX (32). Important: The buttons SOLO (2, 29) take prior- ity over the buttons BOOTH (32), i. e. when at least one button SOLO is pressed, the signals selected by means of the buttons BOOTH will not be monitored / indicated. The buttons BOOTH, however, have the same priority, i. e. when they are all pressed, the mixed signal of the corre- sponding sources will be monitored and indi- cated. 6 Specifications Inputs (sensitivity/ impedance; connection) Mic: . . . . . . . . . . . . . . 0.5 mV/1.8 kΩ; XLR, balanced Line (mono channel): . 1 mV/10 kΩ;
