4. CONNECTIONS
WARNING: To prevent the risk of electric shock, do not connect the loudspeaker with the amplifier switched on. The protective cover over the terminal strip is a safety
feature per CE requirements. Replace this cover after making the signal connections.
1.Remove the insulating cover from the loudspeaker input terminal strip.
2.The positive (+) input terminal of the loudspeaker connects to the positive (+) output of your power amplifier.
3.The negative

4.Using a small phillips screwdriver, secure the connections.
5.Replace the insulating cover over the loudspeaker input terminal strip.
CAUTION:
SUSPENDING THIS SYSTEM SHOULD BE DONE BY QUALIFIED TECHNICIANS FOLLOWING APPROPRIATE SAFETY STANDARDS

• The recommended conductor gauges are | 14 | 8 | 15 | |
listed for AWG (American Wire Gauge) and |

16 | 8 | 25 | ||
Metric WG (Metric Wire Gauge). Note that | ||||

smaller AWG numbers = larger conductors | ||||
and smaller Metric WG numbers = smaller | 25 | 30 | 60 | |
conductors. The Metric WG is equal to ten |

times the nominal conductor diameter in millimeters.
• For cable lengths over 200 feet / 60 m at 8 ohms, and over 100 feet / 30 m at 4 ohms, the conductor sizes needed for less than 0.5 dB power losses are rarely practical for physical and cost reasons. As a practical compromise for these situations the recommended conductor gauge is 10 AWG or 25 metric.
