MAINTENANCE AND WARRANTY
While we have chosen the best components to make this product as rugged and reliable
as possible, some parts in audio products (potentiometers, faders, switches) are subject
to wear which is a matter of operation cycles, and not of time.
In many cases, malfunction of electro-mechanical parts occurs due to dust
contamination, which may require cleaning of such parts. As the inside of such
parts is not accessible, a common practice is to use cleaning fluids in the shape
of sprays. Please be reminded that many of such fluids contain chemicals which
may wash away the dust but at the same time corrode or damage contact
surface and may cause cosmetic damage to other parts. We hence explicitly
exclude any claims for exchange of damaged part due to mechanical
or chemical impact.

PLACEMENT TIPS
Avoid placing loudspeakers in the corners of a room. This increases the low-frequency
output and can cause the sound to be unclear and indistinct.
Avoid placing loudspeakers against a wall. This, too, increases the low frequency
output, though not as much as corner placement. However, if you do need to reinforce
the low frequencies, this is a good way to do it.
Avoid placing the active speakers directly on a hollow stage floor. A hollow stage can
resonate at certain frequencies, causing peaks and dips in the frequency response of
the room. It’s better to place the speakers on a sturdy table or tripod stands.
Position the speakers so the high-frequency drivers are two to four feet above ear level
to the audience to maintain high frequency quality.
