as well as on a permanent contact with them, the ARQIS line of speakers is designed
for fixed installation, especially in environments in need of a compact speaker offering
high output, easy installation, long-term reliability and excellent sound quality.

The connection cables which connect the amplifiers output and the speaker should be
of good quality, have sufficient conductor area and be as short as possible. The latter
fact is especially important when the distance is long and the load impedance low (4-8
). A cross-section of at least 2.5mm2is recommended for distances up to 10m; 4 or
6mm2for longer distances. Following formula gives the required section, assuming
4% losses:

Always respect the polarity. All models have an Euroblock connector, and a
second connector (Euroblock or Speakon®, depending on model), thereby
facilitating the parallel connection of speakers.

Consider following general rules:
Place the speakers on a solid and firm surface. Subwoofers placed directly and
horizontally on the ground have a higher output than hanged or directly on the floor,
but vertically. No obstacles should stand between the enclosures and the audience.
The high frequencies are very directive compared to the low frequencies, so that any
obstacle will impair their response. In case large audiences must be addressed, a
better long distance sound propagation will be achieved if the enclosures are flown
high enough.
IN ST AL LA TI ON
In the ARQIS series, the best way to install the enclosure was studied for each model.
Each model from the ARQIS range is supplied with the optimal installation system.
ARQIS205 / ARQIS208 / ARQIS110 / ARQIS 112 / ARQISSB10 / ARQISSB15 also have
built-in M8 rigging points for suspension from a compatible structure or "truss" using
steel cables.
IMPORTANT NOTE
The equipment must in no case be suspended using its carrying handles (if any); use
the appropriate accessories for each application. Whenever a ceiling/wall mounting
bracket is used, it is mandatory to add a redundant safety system. Use wire ropes,
slings or chains of the appropriate diameter to prevent the fall of the speaker in case
the main mounting system is pulled out.
