13. Operating the ACCESS SYSTEM
− Make sure to observe the instruction in the loudspeaker’s manual as well as in the
included safety and mounting Instructions for loudspeakers and accessories.
− Switch off all equipment and turn off all controls.
− Wire the ACCESS System according to the pin diagrams as shown before.
−
Now switch on the peripheral equipment first (mixing console, effects etc.), fol-
lowed by the ACCESS Controller and the power amplifiers. Always use the before
mentioned switching order. Otherwise switching noises may damage the system.
−
If there is interference, turn off all appliances in the reverse order and check all
cable connections.
−
Turn up the input controls of the amplifiers. If there is interference, turn off all
appliances in the reverse order and check all cable connections.
−
Next, turn on the ACCESS Controller and the other peripheral equipment and
make sure there is no interference.
−
Now put a low level signal into the system and check for the correct function of
the ACCESS System. In doing so, all amplifier input controls need to be turned off
again. Turn on the control for the left high channel and check that the correct
high signal is coming out of the high chassis in the left speaker. The Sense LED for
the high channel of the respective ACCESS C5 Controller will light up green at a
level of at least ---40dB. If the wrong LED lights up or a wrong (i.e. high signal from
a bass speaker) or distorted signal occurs, then there is a mistake in the wiring.
−
The system is now ready to operate. The power amplifiers can now be turned on
all the way (see also LEVEL). Use the LEVEL control on the ACCESS Controller to
set the level of the ACCESS System to the desired setting.
− The levels on the mixing console can now be turned up. When turning off the sys-
tem, the input controls for the power amplifiers should be switched off first followed
by the amplifiers. After that, the other appliances can be turned off.
