IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions
2. Keep these instructions
3. Pay attention to all warnings
4. Follow all instructions
5. This professional device needs to be installed by qualified personnel only.
6. Danger: Exposure to high sound levels may cause a permanent hearing
loss. Individuals vary considerably to sound pressure level induced
hearing loss but nearly everyone will lose some hearing if exposed to
high sound pressure levels for a sufficient amount of time. Therefore
it is recommended that all persons exposed to equipment capable of
producing high sound pressure levels, such as this amplifier, be protected
by hearing protection while installing or operating this unit.
7. Make sure to only use power outlets conform to the power requirements
listed on the back of the unit.
8. Do not connect the inputs / outputs of amplifiers or consoles to any
other voltage source, such as a battery, mains source, or power supply,
regardless of whether the amplifier or console is turned on or off.
9. Do not drive the inputs with a signal level higher than that required to
drive equipment to full output.
10. Do not run the output of any amplifier back into another input.
11. This unit has NOT been designed for use in mobile applications, such
as: mobile discobars, mobile PA systems, Live bands, audio rental
systems,… Using it in such application will lead to product damages and
safety risks.
12. Do not use this apparatus near water
13. Clean only with dry cloth.
14. Do not block any ventilation openings. Install in accordance with the
manufacturer instructions.

15. Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
16. Do not defeat the safety purpose of the polarized or grounding plug.
Always use the device with a grounded mains power plug. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
17. Protect the power cord from being walked on, pinched or damaged.
Particularly at the plugs, connectors and at the point where they exit
from the apparatus.
18. Only use attachments/accessories specified by the manufacturer.
19. Unplug the apparatus during lightning storms or when unused for long
periods of time.
20. Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart or rack is used,
use caution when moving the cart/apparatus combination to avoid injury
from tip-over.
21. Refer all servicing to qualified personnel. Servicing is required when the
apparatus has been damaged in any way, such as power supply cord
or plug is damaged, liquid has been spilled or objects have fallen into
the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.
22. WARNING: To reduce the risk of fire or electric shock, do not expose this
apparatus to rain or moisture. The apparatus shall not be exposed to
dripping or splashing and that objects filled with liquids, such as vases,
shall not be placed on apparatus.
23. WARNING: The mains plug/appliance coupler is used as disconnect
device, the disconnect device shall remain readily operable.

24. This lightning flash with arrowhead symbol within an equilateral triangle
is intended to alert the user to the presence of non-insulated “dangerous
voltage” within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock.
- Warning: To reduce the risk of electric shock, do not remove cover (or
back) as there are no user-serviceable parts inside. Refer servicing to
qualified personnel.
- The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and maintenance
instructions in the literature accompanying the appliance.
25. Protective earthing terminal. The apparatus should be connected
to a mains socket outlet with a protective earthing connection.
26. Correct Disposal of this product. This marking indicates that this
product should not be disposed with other household wastes
throughout the EU. To prevent possible harm to the environment
or human health from uncontrolled waste disposal, recycle it responsibly
to promote the sustainable reuse of material resources. To return your
used device, please use the return and collection systems or contact the
retailer where the product was purchased. They can take this product for
environmental safe recycling.
27. No naked flame sources, such as lighted candles, should be placed on
the apparatus.
28. Do not install this equipment in a confined or building-in space such
as a book case or similar unit, and remain a well ventilation conditions
at open site. The ventilation should not be impeded by covering the
ventilation openings with items such as newspaper, table-cloths, curtains
etc.

1. Channel 2 unbalanced input and link RCA connector: connect
the line level input signal for channel 2 here. Line level is 0 dBV.
Input and link RCA connector are internally connected 1 to 1.
2. Channel 2 overload led: when this led lights up, you are
overloading the input. Lower the input signal immediately to
prevent the amplifier from shutting down.
3. Channel 1 unbalanced input and link RCA connector: connect
the line level input signal for channel 1 here. Line level is 0 dBV.
Input and link RCA connector are internally connected 1 to 1.
This connector is also used in the bridge mode.
4. Channel 1 overload led: when this led lights up, you are
overloading the input. Lower the input signal immediately to
