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 ). A cross-section of at least
2
2.5mm is recommended for distances up to 10m; 4 or 6mm
gives the required section, assuming 4% losses:
Cross section in mm
Always respect polarity. All connections are Speakon® type. The pin-out is indicated in the
diagram. The back panel connexion plate has a second Speakon® connector to connect
loudspeakers in parallel. Together with this manual you'll find a spare Speakon® connector.

6. RECOMMENDED AMPLIFIER

Following table shows the output power of the amplifier adequate to each acoustic system:
DACORD T108i between 150 and 300W
DACORD T208i between 300 and 600W
DACORD H206i between 220 and 440W
DACORD H208i between 300 and 600W
DACORD SB212 between 700 and 1400W

7. PRE-AMPLIFYING MIXERS

Avoid excessive gain adjustments in the equalizer or tone control sections.

8. PLACEMENT

Consider following general rules:
Place the acoustic enclosures on solid and firm surfaces. The Sub bass speakers will
prove more effective if placed on the floor horizontally, instead of flying, elevating or placing the unit
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.
