Important Safety Instructions

Before pushing your loudspeaker volumes to the edge, take a few minutes to read

these instructions carefully. This little time might avoid claims afterwards.

1. Keep this manual for future reference.

2. Clean only with dry cloth.

3. Do not operate near heaters or place it on other apparatus which produce a lot of heat.

4. Take care for the speaker leads. Never use damaged leads and install them in such a way that no one can walk on it.

5. Only use accessories speciﬁed by the manufacturer.

6. Make sure the mounting surface can easily support the speaker’s weight.

7. Use only industry-accepted rigging tools and methods.

8. Choose the right speaker for the right job.

9. Use sufﬁcient loudspeakers and avoid death spots.

10. No main power shall be connected to the loudspeakers.

11. This apparatus should only be serviced by qualiﬁed personnel. If not, the warranty might be void.

12. Removal of the grill causes risk to loudspeaker damage.

13. Use cables of the right gauge, certainly for long runs.

14. Use cables with clear colour codes and maintain polarity throughout the whole system.

15. Switch ampliﬁers on with the volumes turned completely down to avoid loud clicks and clacks.

16. Avoid loud feedback for this is a main speaker killer!

17. Please check the units’ condition after unpacking. If the outside of the carton box has been damaged, inform your shipper

immediately.

Music colours our lives but too much sound might damage yours and other’s hearing permanently!

Being exposed to loud sound levels over a long time can cause severe hearing loss. Don’t forget to consult the local

law directions regarding producing sound in public places. In some countries ear protection is obliged when the

continuous sound level over 8 hours time is 80dB (A). Each halving of time allows an increase of 3dB.

Too weak ampliﬁers can burn your speakers

By pushing your ampliﬁer or its inputs too much, your amp can produce more power than the power published in his manual.

This power is not always clean and can be very distorted. When such signal is fed into your loudspeakers for a longer period,

damage can be the result. Don’t cut in the budget of your ampliﬁer. A loudspeaker can demand to ten times the average power

to reproduce those smashing sonic bursts you are kicking on. If your ampliﬁer has enough reserve power, your sound will remain

clear. When you squeeze your amp’s throat, he’ll be pushed to produce sounds which will kill your tweeters ﬁrst.

Protection systems are not built to be activated all the time, they are there to warn you and to give you a safe margin!

Safety information

Overload Protection

All MASK models have a unique overload protection, which only comes into the signal

path when needed. When too much power is fed into your MASK, ﬁrst a red led will

blink. When you neglect this warning, the overload protection will disconnect the signal

going to the loudspeakers and the red led will remain on. Turn down the level and after

about 5 seconds cooling down your favourite music will be heard again. When you

don’t want to work on your client’s nerves, don’t activate the overload protection !
