5 Installation and starting up

Unpack and carefully check that there is no transportation damage before using the unit. Keep
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.

Establish all connections as long as the unit is switched off. Use the shortest possible high­quality cables for all connections.

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.

5.1 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.

7 Operation

Connect microphones to the low-impedance XLR inputs (MIC, 3) or the high-impedance 1/4"
inputs (MIC/LINE, 4).

Connect musical instruments to the 1/4" inputs (MIC/LINE, 4).
Connect the speaker boxes via the supplied speaker cables to the [SPEAKER OUT] sockets (19)

on the rear panel of the unit.
Use the RCA sockets [TAPE PLAY] (20) on the rear panel of the unit to connect CD player or tape

devices for additional inputs.
Use the RCA sockets [TAPE REC] (21) on the rear panel of the unit to connect recording devices

or the like.
The unbalanced [MAIN OUT] socket (15) provides the master signal with line level.
The unbalanced [REVERB OUT] socket (14) 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.

Use the unbalanced [AUX IN] socket (13) for additional inputs, or to lead the processed signal
from an external effects device back into the signal path of the power mixer.

You can connect a foot switch (not supplied) to the two-pole [FOOT SW] socket (12) to turn the
internal reverb function on or off.

Insert the plug of the mains cable (18) into an earthed mains wall outlet.

When all connections have been established, turn on the device using the main switch (9). The
power LED (10) lights up.

You can adjust the volume of the individual signals with the [VOLUME] controls (5) in each
channel. The overall volume is set by the [VOLUME] control (17) in the master section.

Turn the [TONE] control (1) to shape the sound of the individual signals in each channel. There
is an additional 3-band EQ with [LOW] (6), [MID] (7) and [HIGH] (8) controls for the overall signal
in the master section.

You can set the reverb level for each channel separately with the [REVERB] controls (2). The
overall reverb level can be adjusted using the [REVERB] control (16) in the master section.

Use the [TAPE] control (11) to adjust the playback volume of the device connected to the

9 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.

10 Cleaning

Clean the device componetns 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.
