8. Connection and control elements
Also pay attention to the fold-out page.
a) Mono channel accesses
1) Microphone input „MIC“ (XLR socket)
The mono channel accesses have a low-noise, high-quality symmetric
XLR microphone input each. You can connect your microphone to this
microphone input with its high headroom. The input is suitable for
dynamic or condenser microphones.
A condenser microphone usually requires an extra voltage supply inasmuch as it does not have its own voltage supply, e.g. a battery. The
mixing desk supplies this so-called phantom feed to the microphone
input at the push of a button (PHANTOM switch (27)).
The phantom feed of the mixing desk is 48V. Before you
turn on the phantom feed, check that this corresponds to
the required voltage of the condenser microphone. Also
note the corresponding details on phantom feed in point
„PHANTOM switch (27)“.
Observe the technical data (output level) of the connected
microphone. Do not connect any microphones that do not
harmonise with the mixing desk input.
Do not connect any asymmetric microphones when the phantom feed
is activated.
2) LINE input LINE IN
Each mono channel access has a symmetric LINE input. You can connect a playback source with
LINE level to this 6.3 mm jack socket, e.g. a keyboard. The input is suited for symmetric as well as
asymmetric connection.
Please note that only one signal type may be connected per mono channel access. Either connect LINE or the microphone input. Do not use the inputs LINE (2) and MIC (1)
simultaneously.
Observe the technical data (output level) of the connected playback device. Do not connect any devices that do not harmonise with the mixing desk input.
3) LOW-CUT filter button
By pressing this button, you activate a high-pass filter for the mono channel access. This filter helps
to eliminate deep frequency signals (e.g. humming).
The filter has the following parameters: 18dB/octave/ -3dB 75 Hz.

8. Connection and Control Elements
(4) GAIN control
With the GAIN control, you amplify or weaken the input signals of the respective channel. The input
level should be selected in such a way that the PEAK display of the channel does not or only infrequently light up.
The GAIN control scale shows two different sections. The control range between –10dB and –60dB
refers to the signals on the microphone input. The control range between +10dB and –40dB refers
to the signals on the LINE input.
If you turn the control clockwise, the level of the input signal increases, if you turn it counter-clockwise, it reduces.
Please also not the instructions in the chapter „Setting the input level“.
5) EQ section (equalizer)
Each mono channel access has a three-band equalizer for sound setting. This consists of a HI control, a MID control and a LO control. With the equalizer, you influence the sound of the signal and
can therefore give it a very soft or hard sound.
Setting „-15“ = maximum decrease of the trebles or midtones or basses
Setting „+15“ = maximum increase of the trebles or midtones or basses
HI control:
With the HI control you can
Raise the trebles of the
respective channel or
lower them.
Parameters: 12kHz +/- 15dB
MID control:
With the MID control you can
Raise the midtones of the
respective channel or
lower them.
Parameters: 2.5kHz +/- 15dB
LO control:
With the LO control you can
Raise the basses of the
respective channel or
lower them.
Parameters: 80Hz +/- 15dB
In position „0“, the signal is played back neutral.
The equalizer settings can also be made in connection with the LOW-CUT filter (3).
6) AUX1 control (AUX POST)
With this control, you set the signal ratio of the respective channel access at the AUX1-SEND (23)
output. The control is post-EQ, meaning the signal is picked up behind the equalizer section.
If the control is all the way to the left (turning counter-clockwise), no signal is picked up at the
AUX1-SEND output. In central position, the signal is transmitted to the AUX1-SEND output without
level change. In the range from 0-15dB, the signal is amplified in accordance with the control setting.
7) PRE/POST switch
With this switch, you set the PRE/POST property of the AUX1 control.
If the switch is depressed, the AUX1 control is PRE fader, meaning the control works with a signal that
is picked up before the channel level control. The channel level control and the MAIN fader do not influence the signal which is sent to the AUX1 SEND output. The signal level on the AUX1 SEND output is
set by the AUX1 control.
37
8. Connection and Control Elements
The PRE fader setting is often used when the monitor mix or a monitor system are controlled with the AUX signal.
If the switch is depressed, the AUX1 control is POST-fader, meaning the control works with a signal
that is picked up after the channel level control. In this switch position, the signal is influenced by
the AUX1 control and the channel level control.
The POST-fader setting is often used when an effect device (e.g. reverb) is controlled
with the AUX signal.
8) AUX-2 control
With this control, you set the signal ratio of the respective channel access at the AUX2-SEND (23)
output. The control is post fader, meaning the control works with a signal that is picked up after the
channel level control. The signal is influenced by the AUX2 control and the channel level control.
If the control is all the way to the left (turning counter-clockwise), no signal is picked up at the
AUX2-SEND output. In central position, the signal is transmitted to the AUX2-SEND output without
level change. In the range from 0-15dB, the signal is amplified in accordance with the control setting.
(9) PAN control
The PAN control is a kind of balance setting for the mono signal. With this control, you set the distribution of the channel signal at the left and right output.
If the control is set to LEFT, the mono signal of the channel is only output on the left output. In the
position „RIGHT“, the mono signal of the channel is only output on the right output. In center position (indicated by a small stop), the channel signal is output evenly on the left and the right output.
10) SIG-LED
The „signal present LED“ is lit when the input signal exceeds –20dBu. This indicates that there is an
input signal.
11) PEAK-LED
The PEAK LED is lit when the level of the input signal is too high.
If the input level is too high, the signal gets distorted. As a consequence, the downstream devices are oversteered or damaged. See the chapter „Setting the input level“.
12) Channel level control
With the channel level control, you can set the level ratio of the respective channel access at the
MAIN outputs. The channel fader sets the level of the respective channel access in the mix.
Position „“ = minimum channel level in the mix
Position „10 dB“ = maximum channel level in the mix
The channel control should be set to the position „“ when the input is not used. This
reduces interference like e.g. noise.

8. Connection and Control Elements
b) Stereo channel accesses
Stereo channel accesses partially have the same controls/switches as the mono channel accesses. For a detailed description refer to the mono channel access.
13) LINE input MONO L/R
The stereo channel accesses have two asymmetric 6.3 mm jack sockets for signals with LINE level each. Via these two jack sockets, you can
connect a stereo playback source, e.g. a CD player. For stereo mode,
both inputs MONO/L and R must be accessed with a LINE signal.
Jack socket MONO/L = input for the left stereo signal or
the mono signal
Jack socket R = input for the right stereo signal
The stereo input can also be operated in mono. In this case,
feed the mono signal at the jack marked with MONO/L.
If only the left input is connected, the device plays in mono.
78
When both inputs are connected, the device plays in
stereo.
Do not connect any devices that do not harmonise with the
mixing desk input. Also see the „Technical Data“.
14) Level switch –10/+4
With this switch you can adapt the stereo LINE input to the level of the
playback source. You can chose between the two standard input level
values –10dBV and +4dBu. In the setting –10dBV, the input is more
sensitive.
Switch depressed = input level +4dBu
Switch not depressed = input level -dBV
Observe the technical data (output level) of the connected
playback device. Do not connect any devices that do not
harmonise with the mixing desk input.
15) EQ section (equalizer)
Each stereo channel access has a three-band equalizer for sound setting like the mono channel
access. For a detailed description, see mono channel accesses, point „(5) EQ section)“.
16) AUX1 control (AUX POST)
See mono channel accesses, point „(6) AUX1 control“.

18) AUX-2 control
See mono channel accesses, point „(8) AUX2 control“.
(19) PAN control
The PAN control is the balance setting for the mono signal. With this control, you set the distribution of the left and right channel signal. Only the left input signal is played back if the control is
turned to the “LEFT” position. The right input signal is played back when the control is set to
„RIGHT“. In central position (indicated by a slight stop), the left and the right channel signal are output evenly.
20) Channel level control
See mono channel accesses, point „(12) channel level control“.
c) MASTER section
21) Stereo EFX-RETURN-1 inputs
These inputs are used as return feed points for
the signal of effect devices. This means, signals
sent to an effect device, e.g. via the AUX-SEND
outputs, can be returned to the mixing desk via
the EFX-RETURN inputs.
The EFX-RETURN inputs can be connected to a
mono or stereo effect device.
Stereo connection:
Connect the left output of the effect device to
the EFX-RETURN input marked „1LEFT/MONO“.
Connect the right output of the effect device to
the EFX-RETURN input marked „1 RIGHT“.
Mono connection:
Connect the mono output of the effect device
to the EFX-RETURN input marked „1
LEFT/MONO“. The socket marked „1 RIGHT“
is not occupied. Then the mixing desk automatically distributes the mono signal to both
MAIN output channels.
The EFX-RETURN-1 signal is assigned to MAIN
mix. Pressing the button EFX1-TO-AUX1 (42)
additionally also feeds the EFX-RETURN-1 signal
to the AUX1 signal path.
22) Stereo EFX-RETURN-2 inputs
These inputs are used as second feed points for the signal of effect devices. This means, signals
sent to an effect device, e.g. via the AUX-SEND outputs, can be returned to the mixing desk via the
EFX-RETURN inputs.
40
77
10. Raccordement
The EFX-RETURN inputs can be connected to a mono or stereo effect device.
Stereo connection:
Connect the left output of the effect device to the EFX-RETURN input marked „2 LEFT/MONO“.
Connect the right output of the effect device to the EFX-RETURN input marked „2 RIGHT“.
Mono connection:
Connect the mono output of the effect device to the EFX1-RETURN input marked „2 LEFT/MONO“.
The socket marked „2 RIGHT“ is not occupied. Then the mixing desk automatically distributes the
mono signal to both MAIN output channels.
The EFX-RETURN-2 signal is assigned to MAIN mix. Pressing the button EFX2-TO-AUX2 (39) additionally also feeds the EFX-RETURN21 signal to the AUX2 signal path.
23) AUX-SEND-1 & 2 outputs
These two asymmetric 6.3 mm mono jack sockets carry the total of the individual channel signals
in dependence on the AUX 1 and/or AUX 2 control setting at the respective channel access.
You can connect effect devices or the monitor system to the AUX-SEND outputs.
24) TAPE-IN input / TAPE-OUT output
You can connect a recording device, e.g. a cassette deck or a reel-to-reel player to these stereo
cinch sockets and record/play back the mixing desk signal.
The white socket „L“ is for the left signal, the red socket „R“ for the right signal.
TAPE-OUT output:
The MAIN MIX signal of the mixing desk is supplied at the TAPE-OUT output. However, the output
level is independent of the MAIN MIX fader setting. The level is controlled by the channel level controllers, the GAIN controllers and the channel sound controls.
TAPE-IN input:
At the TAPE-IN input, you can feed the signal of the recording device back to the mixing desk.
Only connect devices to the TAPE inputs/outputs that work with a normal cinch level.
25) CONTROL-ROOM outputs (CTRL/OUT)
You can connect an amplifier or active loudspeakers to these asymmetric 6.3 mm mono jack sockets. These outputs are usually used to control a monitor system in the control room.
The MAIN MIX signal resp. TAPE-IN signal is applied at the CONTROL-ROOM outputs. The position
of the switches (31) and (32) decides which signal is played back.
76
The socket marked with „L“ carries the left signal, the socket marked with „R“ the right signal.
41
10. Raccordement
The level of the CONTROL-ROOM output is set via the level control „CONTROL-ROOM and
PHONES“ (33).
26) Headphone output HEADPHONES
A set of stereo headphones can be connected to this 6.3 mm socket. The input signals can be preheard on the headphones or you can listen in on the output signal.
Broche 1 = masse (blindage)
Broche 2 = plus + (hot)
Broche 3 = négative - (cold)
The output level of the headphone output is set via the level control „CONTROL-ROOM and
PHONES“ (33).
Only use headphones with a minimum impedance of 32 Ohm. Do not use any mono
headphones or headphones with an impedance below 32 Ohm, as this may damage
the mixing desk.
Turn the volume at the headphone output to minimum before plugging in or unplugging headphones or before switching the mixing desk on or off. Otherwise there is
the risk of an excessive volume at the headphones output. This might damage your
hearing.
27) PHANTOM switch
With this switch you can activate the phantom feed voltage for the microphone inputs (XLR sockets) of the mono channel accesses. The phantom feed is required for condenser microphones that
do not have their own voltage supply (battery). The red +48V LED lights up when the phantom power is activated. The voltage is +48V DC. If you are in doubt about whether your microphone is compatible, consult a microphone specialist.
Only switch the phantom feed on/off, when the mixing desk is turned off. This prevents the on/off switching noise of the phantom feed from damaging the downstream devices. Plug in the condenser microphones before turning on the phantom feed.
Do not plug in/unplug microphones when the phantom feed is turned on. Switch off
the phantom feed beforehand, otherwise the mixing desk or connected devices may
become damaged. The phantom feed needs approx. 1 minute until it has dropped to
„0V“ after turning it off. Therefore, do not connect a microphone directly after turning the phantom feed off.
The phantom feed effects all microphone inputs. As soon as the phantom power
switch is turned on, a voltage supply runs to every microphone input. Therefore, it is
not possible to operate asymmetric and symmetric condenser microphones at the
same time. Do not plug in any asymmetric microphones when the phantom feed is
activated as this leads to damage.
28) PHANTOM LED
The PHANTOM LED lights up when the phantom feed for the microphones is turned on.
29) POWER LED
When the device is switched on, the operating indicator lights up.

30) Balance indicator
The balance indicator displays the level of the left and right MAIN output signal. Even with loud
music passages, this display should not exceed the 0dB value. This prevents oversteering the signal.
An excessively high signal level leads to signal distortion, a too low signal level to a bad
signal/noise ratio.
32) 2TK CONTROL-ROOM & PHONES switch
If this switch is pressed, the signal, which is applied at the TAPE-IN output is (24) played back on
the CONTROL-ROOM output (25) and the headphone output (26).
This allows you to control the signal of the recording device connected to the TAPE IN inputs.
33) Level control CONTROL-ROOM & PHONES
With this control, you set the output level on the CONTROL-ROOM output (25) and the headphone
output (26).
Control setting „“ = minimum output level
Control setting „MAX“ = maximum output level
74
31) MAIN-MIX CONTROL-ROOM & PHONES switch
If this switch is pressed, the signal, which is applied at the MAIN output is played back on the CONTROL-ROOM output (25) and the headphone output (26).
34) 2TK TO MIX switch
If this switch is pressed, the signal, which is applied at the TAPE-IN input (24), is fed at the MAINMix.
This allows you to control the signal of the recording device connected to the TAPE IN inputs at the
MAIN output.
35) 2TK-LEVEL level control
With this control you set the level of the TAPE-IN input.
Control setting „“ = minimum input level
Control setting „MAX“ = maximum input level
An excessively high signal level leads to signal distortion, a too low signal level to a bad
signal/noise ratio.
36) MAIN-MIX fader (MASTER)
Using this fader, you can set the mixer output level at the MAIN OUT output.
Fader setting „“ = minimum output level
Fader setting „10dB“ = maximum output level
An excessively high output level can oversteer the downstream device and lead to a
distorted signal.
43
8. Connection and Control Elements
37) AUX2-SEND level control
With this control you can set the level of the AUX2-SEND signal total, which you branched off from
the individual channel accesses with the aid of the AUX 2 control, at the AUX-SEND2 output.
38) AUX1-SEND level control
With this control you can set the level of the AUX1-SEND signal total, which you branched off from
the individual channel accesses with the aid of the AUX 1 control, at the AUX-SEND1 output.
39) EFX2-TO-AUX2
When this switch is depressed, the signal, which is applied at the STEREO-EFX-RETURN2 input
(22), is played back at the AUX-SEND2 output (23).
40) EFX-RETURN2 level control
With this control, you can set the level of the signal, which is fed via the stereo EFX-RETURN-2
inputs (22).
Control setting „“ = minimum level
Control setting „+20dB““ = maximum level
41) EFX-RETURN1 level control
With this control, you can set the level of the signal, which is fed via the stereo EFX-RETURN-1
inputs (21).
Control setting „“ = minimum level
Control setting „+20dB““ = maximum level
42) EFX1-TO-AUX1
When this switch is depressed, the signal, which is applied at the STEREO-EFX-RETURN1 input
(21), is played back at the AUX-SEND1 output (23).
d) Rear side
43) MAIN jack socket outputs
The MAIN Mix output signal is applied at the symmetric (balanced) 6.3 mm jack socket outputs.
The socket marked with „L“ carries the left output signal, the socket marked with „R“ the right output signal. You can connect the input of your amplifier to these outputs.
44
73
8. Connection and Control Elements
44) MAIN XRL outputs
The MAIN Mix output signal is applied at the symmetric (balanced) XLR outputs. The MAIN-XLR output carries the same signal as at the MAIN jack socket outputs. The socket marked with „L“ carries the left output signal, the socket marked with „R“ the right output signal. You can connect the
input of your amplifier to these outputs.
45) ON/OFF switch
The mixer is switched on and off using this switch.
Switch in the „ON“ position = mixing desk is switched on
Switch in the „OFF“ position = mixing desk is switched off
The external power pack still consumes a slight power quantity when the on/off
switch of the mixing table is set to „OFF“. In order to completely separate the device from the power net, you have to pull the power plug of the power pack out of
the outlet.
Before you turn the device on or off, set all level controls for the outputs to minimum.
46) AC-POWER connection socket
The low-voltage plug of the supplied plug-in power unit is connected to this socket.
47) External power pack
Power pack for the voltage supply of the mixing desk
9. Setting up the device
The mixing desk is suitable for table top use or for mounting in a 19“ (483 mm) rack system.
When setting up with other equipment, make sure that the appliance is well ventilated. Keep a sufficient distance to heat sources. Do not place the device directly next
to heat sources, e.g. an amplifier. Do not point any strong beams or light sources
onto the device. This may lead to overheating (risk of fire).
The heat extraction of the device may not be obstructed. Never place the device on
a soft surface such as, for example, a carpet or a bed etc. Do not cover up the ventilation openings of the device. The air circulation may not be obstructed by objects
such as magazines, table cloths, curtains or similar. This hinders the heat extraction
from the device and can lead to overheating (risk of fire!).
For rack installation an additional ventilator may be necessary to cool the resulting
heat from other appliances.
Do not drill any holes or screws into the housing in order to attach the appliance
somewhere, this will damage it and even impair its safety.
72
45
9. Setting up the device / rack mounting
When installing the product, ensure that it is on a safe stand which is itself on stable ground. If the appliance falls down, it may injure persons.
Make sure that the connection cable is not being pinched or damaged by sharp
edges. Always lay the cables so that no-one can stumble over them or become
entangled in them. There is risk of injury!
The cables must have a sufficient length. Avoid mechanical strain on the cables. This
may damage the cables or the device. Danger of fatal electric shock!
When selecting a place to set up the appliance, make sure that direct, intensive sunlight, vibration, dust, heat, cold and moisture are avoided.
No devices with strong electric or magnetic fields, e.g. transformers, motors, wireless telephones, walkie-talkies, PCs, etc. may be located in the vicinity of the mixer
as these can influence the mixer. The mixing desk may also cause interference with
radios or TVs. Make sure there is as great a distance as possible to such devices.
Due to the variety of paints and polishes used for furniture, it cannot be ruled out
that the feet of the device may leave visible residue on the furniture. Therefore the
device should not be placed on valuable furniture surfaces without sufficient protection.
Observe the following operating conditions:
Temperature: +5°C to 35°C
Humidity: 25% - 85% relative air humidity
Table top use:
Place the mixing desk on a straight, level surface. The mounting surface may not be sensitive to
heat. Keep sufficient free space around the mixing desk to ensure heat dissipation.
Use in a rack system:
There are two installation angles included in
the delivery, which you can use to install the
mixing desk in a 19“ rack. The installation
angles are screwed onto the sides of the mixing desk. Loosen the three screws on the
right and the left side of the mixing desk.
Attach the two installation angles with the
same screws. Tighten the screws again.
Only use original screws for attaching the installation angles. Do not use any other
screws.
46
71
9. Setting up the device / rack mounting
After the installation angles are attached, you can install the mixing desk in a 19“ rack. A rack with
openings on both sides is recommended, to allow problem-free installation and connection. There
are four attachment holes each in the installation angles. Attach the mixing desk with 8 sufficiently
dimensioned screws in the rack.
There are various possibilities for integrating the mixer in your system. The connection diagram
shows you one possibility.

The mixing desk is turned on via the On/Off switch. Before connection, disconnect
the mixer and all other devices which are to be connected to the mixer from the
mains voltage (pull mains plug out of the socket). Use only suitable shielded cables
for connection. The use of wrong cables may cause interference and infringe on
safety.
Cables are important connection links in the system, therefore use high-quality, wearresistant cables with high-quality plugs. Do not install the inputs and outputs of the
mixing desk directly next to mains cables. If necessary, cross the cables at a right
angle to prevent interference.
To avoid distortion or mismatching that may damage the appliance, only reproduction
appliances with a cinch output may be connected to the cinch inputs of the mixer. For
this, observe also the connection values in the section “Technical Data”.
The mixing desk requires different types of connections like 3-pole XLR plugs, 6.3 mm jack plugs and
cinch plugs. Some of these plugs are symmetric, others asymmetric, some in stereo and some have
a dual function. The following description provides an overview.

General notice on the plug connections:
You can also connect an asymmetric device to most symmetric inputs. For this purpose, you can
either use a mono jack plug or a stereo plug where the ring and the shaft are connected. With XLR
connection with asymmetric design, PIN1 (ground) and PIN3 (minus) are connected.
a) Mono microphone input
Either condenser or dynamic microphones can be connected to the the microphone XLR input
sockets via a symmetrical line. You can add a phantom voltage for a condenser microphone if necessary. The input is suitable for symmetrical and asymmetrical connection.
Only connect microphones to the microphone inputs, no other signal sources. Do not
use an asymmetric XLR connection when the phantom feed is activated as this may lead
to damage.
48
69
b) Mono LINE input
You can connect a playback source with LINE level to this symmetric 6.3 mm jack socket input, e.g.
a keyboard, a drum machine, etc. The input is suited for symmetric and asymmetric connection.
Please note that only one signal type may be connected per mono channel access. Either connect LINE or the microphone input. Do not use the inputs LINE (2) and MIC (1)
simultaneously.
c) Stereo LINE input
You can connect a stereo playback source with LINE level to the two asymmetric 6.3 mm jack sockets of the stereo inputs, e.g. a CD player. For stereo mode, both inputs MONO/L and R must be
accessed with a LINE signal.
The stereo input can also be operated in mono. In this case, feed the mono signal at the jack
marked with MONO/L. When both inputs are connected, the device plays in stereo. If only the left
input is connected, the device plays in mono.
Jack socket MONO/L = input for the left stereo signal
Jack socket R = input for the right stereo signal
d) Stereo EFX-RETURN inputs
These inputs are used as feed points for the signal of effect devices. This means, signals sent to an
effect device, e.g. via the AUX-SEND outputs, can be returned to the mixing desk via the EFXRETURN inputs.
The EFX-RETURN inputs can be connected to a mono or stereo effect device.
Stereo connection:
Connect the left output of the effect device to the EFX-RETURN input marked LEFT/MONO. Connect the right output of the effect device to the EFX-RETURN input marked RIGHT.
Mono connection:
Connect the mono output of the effect device to the EFX-RETURN input marked LEFT/MONO. Then
the mixing desk automatically distributes the mono signal to both MAIN output channels.
These two asymmetric 6.3 mm mono jack sockets carry the total of the individual channel signals
in dependence on the AUX 1 and AUX 2 control setting at the respective channel access. You can
connect effect devices or the monitor system to the AUX-SEND outputs.
f) TAPE IN input / TAPE OUT output
You can connect a recording device, e.g. a cassette deck or a reel-to-reel player to these stereo
cinch sockets and record/play back the mixing desk signal. The white socket „L“ is for the left signal, the red socket „R“ for the right signal. Use standard cinch cables for connection.
68
49
TAPE-OUT output:
The signal of the mixing desk is supplied at the TAPE-OUT output. The stereo cinch output is connected to the input of the recording device, e.g. cassette recorder, reel-to-reel player or CD
recorder.
TAPE-IN input:
At the TAPE-IN input of the mixing desk, you can feed the signal of the recording device back to the
mixing desk. The TAPE-IN input is connected to the output of the recording device.
g) CONTROL-ROOM output
You can connect an amplifier or active loudspeakers to these 6.3 mm mono jack sockets. These
outputs are usually used to control a monitor system in the control room.
c) Section MASTER
h) Headphone output
At this 6.3-mm jack bushing, a commercially available headphone with a 6.3mm jack bush can be
connected.
Only use headphones with a minimum impedance of 32 Ohm. Do not use any mono
headphones or headphones with an impedance below 32 Ohm, as this may damage
the mixing desk.
Turn the volume at the headphone output to minimum before plugging in or unplugging
headphones or before switching the mixing desk on or off. Otherwise there is the risk
of an excessive volume at the headphones output. This might damage your hearing.
i) MAIN jack socket outputs
The MAIN Mix output signal is applied at the symmetric (balanced) 6.3 mm jack socket outputs.
You can connect the input of your audio amplifier to the MAIN output of the mixing desk. The
socket marked with „L“ carries the left output signal, the socket marked with „R“ the right output
signal.
j) MAIN-XLR outputs
The MAIN Mix output signal is applied at the symmetric (balanced) XLR outputs. You can connect
the input of your audio amplifier to the XLR MAIN output of the mixing desk. The socket marked
with „L“ carries the left output signal, the socket marked with „R“ the right output signal.
k) Connection of the Voltage Supply
The mixer and all connected devices have to be switched off. Ensure that all the electrical connections and connection cables between the appliance and any extension
cables conform to the regulations and comply with the operating instructions. In
order to completely separate the device from the mains voltage, you must unplug its
mains plug. Therefore, the mains outlet must be easily accessible to unplug the
mains plug without obstruction.
When connecting up make sure first that the voltage data on the type plate of the
power pack is compatible with the mains voltage available. Incorrect settings will
lead to a lot of damage. Use the supplied power pack, do not connect another
power pack.
50
67
10. Connection
If extension cables are used, be certain that they have the sufficient electrical load
capacity. When using extension cables, also observe the safety notices for the mains
cable and the instructions by the manufacturer of the extension cable.
Plug the low-voltage plug of the power pack into the AC-POWER connection socket (46) at the mixing desk and tighten the coupling ring. Insert the plug-in power unit into a (230V~/50Hz) mains
socket (230V~/50Hz).
11. Initial operation
Only put the appliance into operation when you have become familiar with its features and these operating instructions. Check again that all connections are correct. Do not put the product into operation if it is damaged.
Listening to music at excess volumes may damage your hearing.
The amplifier for this equipment should always be the last to be turned on and the
first to be turned off. This prevents undesired noises (that can arise when turning
the mixing desk on and off) that can also damage the amplifier and the loudspeakers.
Make sure that the connected devices are not overloaded. Reproduction should not
be distorted under any circumstances. If distorted music signals can be heard
although the volume on the amplifier has not been set too high, switch off the mixer
immediately and check the connection. If you can find no errors in the connection,
please contact a specialist.
The device may only be operated by persons familiar with the operating instructions.
Keep other persons and children away from the mixing desk.
66
Non-observance of the order described in the following when switching the mixer on
and off could damage the loudspeakers or the connected amplifier.
Switching on:
• Make sure that all level controls for the outputs are set to minimum volume.
Switch on first those playback appliances that are already connected to the mixer.
• Turn on the mixing desk, the operating LED lights up.
• Switch the connected amplifier on last.
• This appliance is now ready for operation.
Switching off:
• To switch off the mixing desk, turn the volume of all mixing desk outputs and the amplifier first
of all to minimum.
• Switch off the amplifier.
51
11. Initial operation
•
•
Turn off the mixing desk and then the playback devices (CD player etc.).
If you do not require the mixer for a longer period, disconnect the mains plug from the socket.
b) Adjusting the input level control
Using the input level controls, match up the mixing desk input to the output signal of the playback
device connected.
• Make sure that all level controls for the outputs are set to minimum volume.
• Set the control „GAIN“ (4) to the left-hand stop position (minimum).
• Set the equalizer control to the center position.
• Apply an audio input signal.
• Slowly turn the GAIN controller clockwise; the SIG-LED (only mono channel access) starts to blink.
With the GAIN control, set the input level in such a way that the PEAK display (only mono channel access) only lights up occasionally or not at all. If the PEAK display lights up, the input signal
is distorted. Reduce the input level.
• If the equalizer setting is changed, it might be necessary to adjust the input level.
• Repeat the setting for all input channels.
• Make sure that the signal never sounds distorted. If this is the case, reduce the level.
The LINE inputs of the stereo channel accesses are not equipped with a GAIN controller.
Adjust the input level with the level switch (14) to the mixing table. Again, the signal may
never sound distorted. If this is the case, reduce the level.
c) Output level
Make sure that the connected loudspeakers and the amplifier are not overloaded.
Reproduction should not be distorted under any circumstances. Set the level of the
mixing desk at the different output in such a way that downstream devices are not
oversteered. Monitor the mixing desk output level with the balance control at the
mixing desk. This should not exceed „0dB“, and the +3dB display may only light up
briefly. The balance level of the mixing desk only shows the MAIN MIX level. The level
of the other outputs is not displayed. Therefore, also observe the balance control of
the connected devices. These may not oversteer. Reduce the mixing desk level or the
input sensitivity of the connected devices.
Make sure the volume is at a suitable level. Excess volume may damage your hearing or the devices.
If the music signal is distorted in spite of the fact that the volume on the amplifier is
not at a high setting, and all the settings on the mixer are correct, then switch off
the mixer immediately and check all connections. If you can find no errors in the connection, please contact a specialist.
52
65
12. Handling
Never plug in the mains plug immediately when bringing the appliance from a cold room
to a warm one. The condensation that forms could destroy the device or lead to an electric shock. Allow the device to reach room temperature before connecting it. Wait until
the condense water has evaporated. This can take some hours.
Avoid operation under adverse ambient conditions, e.g. excess air humidity, dampness,
excess (above 35°C) or too low ambient temperature (below +5°C), dust and flammable
gasses, vapours or solvents.
13. Replacing the Fuse
Fuses may only be replaced when the mains plug has been pulled out and with fuses
of the same type, the same triggering characteristics and the same nominal power.
The use of “fixed”, repaired fuses or bridging the fuse bracket is not permitted.
Only an expert may change the fuse and must be familiar with the corresponding risks and regulations.
14. Care and maintenance
The safety instructions below must be noted before the device is cleaned or maintained:
Unplug the mains plug from the mains socket! Only a specialist who is familiar with
the risks and relevant regulations may carry out repairs or open the appliance.
All connected appliances must be disconnected from the mains before servicing or repairs (pull out
mains plug) can be carried out. The device is maintenance free. For this reason, you should never
open it. If you do open it, the guarantee will be rendered invalid.
Heavy contamination or excess dust may reduce the device insulation. Then the device is no longer
safe to operate and must be separated from the mains voltage. A very dirty device must be cleaned
by an expert.
The outside of the device should be cleaned with a clean dry cloth or brush only. Do not use abrasive cleaning agents or chemical solutions which could damage the housing or impair operation.
Check the technical safety of the appliance regularly, e.g. for damage to the housing or mains
cable etc.
If you have reasons to assume that safe operation is no longer possible, then disconnect the appliance immediately and secure it against inadvertent operation.
64
53
14. Care and maintenance
It can be assumed that safe operation is no longer possible if:
• the mixing desk, the power pack or the power cable show visible damage
• the device no longer functions or not correctly
• the device has been stored under unfavourable conditions for a longer period of time
• the device has been subjected to heavy transport strain
• the device came in touch with liquid, e.g. rain.
15. Troubleshooting
By purchasing this system you have acquired a product that has been designed to the state of the
art and is operationally reliable. Problems and malfunctions may, however, still arise. We should
