within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.
DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.

DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered electrician.
CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.

the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.
Create all connections while the device is off. Use the shortest possible high-quality cables for
all connections. Take care when running the cables to prevent tripping hazards.
NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.

4.1 Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐
ence unobstructedly. It will often be helpful to mount the speakers on tripods. Thus, the sound
will be evenly spread with maximum range throughout the audience area.
Always use high grade cable to connect your equipment. Otherwise you won't reach max‐
imum sound quality.
For optimum results both impedance and power handling of the speakers must match the
requirements of the amplifier. Always follow the technical specifications of the speakers! The
overall impedance of the connected loudspeakers must not deceed the minimum output
impedance of the amp. The amps max. RMS output power should be 50 % above the power
handling capacity of the connected speakers.
If you notice distortion during operation, either the amp or the speaker is overloaded. This may
permanently damage the amp or the speaker. Always reduce the volume when you hear dis‐
tortion.

6 Operation
Connect microphones to the low-impedance XLR inputs [Mic] or to the high-impedance 1/4"
inputs [Line].
Connect musical instruments to the 1/4" inputs [Line].
If desired, connect one or more speaker boxes via a suitable speaker cable to the
[External Speaker] socket on the rear panel of the unit. The overall impedance of the connected
load must not come below 8 Ω. Otherwise, the device will be overloaded.
Use the RCA sockets [CD/Tape Play] on the rear panel of the unit to connect a CD player or tape
devices for additional inputs.
Use the RCA sockets [CD/Tape Rec] on the rear panel of the unit to connect recording devices
or the like.
The unbalanced [Main Output] socket provides the master signal with line level. Here you may
connect a power amp for additional amplification.
The unbalanced [Effects Send] socket provides the combined effect signal that is tapped from
the four channels. Here you can connect an external effects device, which then takes over the
signal processing instead of the built-in reverb function.
If you route the effect signal from the [Effects Send] output into an external effects device, con‐
nect its outlet to the [Aux Input] to lead the processed signal back into the signal path.

You can connect a foot switch (not supplied) to the two-pole [Foot Switch] socket to turn the
internal reverb function on or off.
Connect the mains power connection via the supplied mains cable to an earthed mains power
wall outlet to supply the device with operating voltage.
When all connections have been established, turn on the [POWER] switch. The [Power On] LED
then lights up.
You can adjust the volume of the individual signals with the [Volume] controls in each channel.
The overall volume is set by the [Volume] control in the master section.
Turn the [Tone] control to shape the sound of the individual signals in each channel. There is
an additional 3-band EQ with [Low], [Mid] and [High] controls for the overall signal in the
master section.
You can set the reverb level for each channel separately with the [Reverb] controls. The overall
reverb level can be adjusted using the [Reverb] control in the master section.
Use the [Tape] control to adjust the playback volume of the device connected to the
[CD/Tape Play] sockets.

8 Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable equip‐
ment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a
plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short
circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hifi use.
Instrument cables with two conductors (one core plus shielding) are typical representatives of
the unbalanced transmission. One conductor is ground and shielding while the signal is trans‐
mitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at low
levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred, because this
enables an undisturbed transmission of signals over long distances. In addition to the conduc‐
tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers
the signal, but phase-shifted by 180°.
Introduction
Balanced and unbalanced trans‐
mission

Since the interference affects both cores equally, by subtracting the phase-shifted signals, the
interfering signal is completely neutralized. The result is a pure signal without any noise inter‐
ference.

9 Troubleshooting
In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:
Symptom Remedy
The unit does not work, no sound,
no indicator lights up.
Check the mains connection and the main fuse.
Disconnect the device from the mains power supply.
Open the fuse holder beneath the IEC chassis connector
(21) and check the fuse. If it's blown, replace it by a new
fuse with same specifications. Refit the fuse holder cap
and reconnect the device to the mains power supply.
If the procedures recommended above do not succeed, please contact our Service Center. You
can find the contact information at www.thomann.de.

10 Cleaning
Clean the device components that are accessible from the outside regularly. The cleaning fre‐
quency depends on the operating environment: damp, smoky or particularly dirty environ‐
ments can cause greater accumulation of dirt on the device components.
n Clean with a dry soft cloth.
n Stubborn dirt can be removed with a slightly dampened cloth.
n Never use solvents or alcohol for cleaning.
The fan grids of the device must be cleaned on a regular basis to remove dust and dirt. Before
cleaning, switch off the device and disconnect AC-powered devices from the mains. Use a lintfree damp cloth for cleaning. Never use solvents or alcohol for cleaning.
