5. CONNECTIONS

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 specially important
when the distance is long and the load impedance low (4-8 Ω). A cross-section of at least 2.5mm
recommended for distances up to 10m; 4 or 6mm
required section, assuming 4% losses:
Cross section in mm
Always respect the polarity. All models have a Euroblock connector, and a second connector
(Euroblock or Speakon®, depending on model), thereby facilitating the parallel connection of speakers.

6. RECOMMENDED AMPLIFIER

Following table shows the output power of the amplifier adequate to each acoustic system:
ARQIS 105: between 70 and 150W RMS
ARQIS 106: between 120 and 250W RMS
ARQIS 108: between 150 and 300W RMS
ARQIS 205: between 150 and 300W RMS
ARQIS 208: between 300 and 600W RMS

7. PLACEMENT

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.
