10. Connecting Instructions for the ACCESS System
10.1 Wiring
The speaker is equipped with two parallel EP-5 or with Speakon NL4 connectors.
Make sure that all units are switched off and all controls are turned down be-fore con-
necting your ACCESS system.
−
We recommend the use of high-quality speaker cables provided by Kling & Freitag.
− For connections to the power amplifier inputs, please use 2-pin shielded micro-
phone cable with high-quality connectors.
−
Avoid ground loops (see next chapter)
− Please pay attention to the respective pin diagrams in this manual!
− To ensure an in-phase operation and, consequently, a homogeneous sound, make
sure that the +/- polarity of the speakers at the amplifier is correct.
− When simultaneously using power amplifiers from different manufacturers, be sure
to use the correct specific pin configuration. It may be necessary to modify the pin
configuration on the power amplifiers or on the connectors leading to them.
−
-To avoid loss of power, the cables should have a minimum wire gauge of 2.5 mm²
- more for longer cabled distances. A minimum wire gauge can be easily calculated
with the following formula:
Make sure that the EP-5-‘Male’ socket with the exposed contacts (male) is used
as input to avoid physical contact with dangerous currents!
If several loudspeakers are connected, the signal can be linked through from one loud-
speaker to the next. Please make sure that the total impedance of the loudspeakers R(
Ω) is
not lower than the minimal impedance indicated on the power amplifier.
