DANGER!
Danger for children

Ensure that plastic bags, packaging, etc. are disposed of properly and are not
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.
Do not use the device if covers, protectors or optical components are missing or

damaged.

DANGER!
Electric shock caused by short-circuit

Always use proper ready-made insulated mains cabling (power cord) with a pro­tective 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 regis­tered 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 suffi­cient ear protectors.

NOTICE!
Risk of fire

Do not block areas of ventilation. Do not install the device near any direct heat
source. Keep the device away from naked flames.

NOTICE!
Operating conditions

This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and

NOTICE!
Power supply

Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.

Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

4 Installation

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.

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 audi­ence 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 max­imum 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 dis­tortion.

1 [MAIN LEVEL]

Overall volume control.

2 LED [+48V]

Control LED for phantom power. This LED lights when the phantom power is turned on.

3 LED [POWER]

Control LED for power supply. This LED lights when the device is turned on.

4 [PHANTOM]

Turns on phantom power for the microphone inputs.
The phantom power leads to damage to the device if unbalanced cables are connected. Only switch on phantom

power while exclusively balanced cables are connected.

7 Plug and connection assignment

This chapter will help you select the right cables and plugs to connect your valuable equip­ment 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 trans­mitted 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 conduc­tors ‘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 trans­mission

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 inter­ference.
