14.3 SETTING UP THE INITIAL WIRING
First connect the power supply of the ClubMix to the console. All faders must be down and the Phones control
at 12 o'clock with a headphone set connected.
Connect the power amps or headphones to the Phones outputs and check for any hum buzz or interference. If
this is allright proceed.
b. Now the inputs can be wired up. Check every channel that is wired to your equipment individually. Carefully
listen for noise and/or hum.
c. Connect stereo tape recorders microphones and all other equipment one by one and all signal processors
one at the time and keep checking that your system stays clean. If not carefully check for a ground loop.
14.4 SHIELDING/EARTHING OF AUDlO EQUIPMENT
The shield of any audio connection should be connected at one end only. If not ground loops and high
frequency crosstalk will be the result.
Connect the shield as a general rule to the signal source end. In high R.F. area's it is wise to ground the other
end of shield via a 0.01 uf capacitor. This will be a short circuit at high frequencies but not at low frequencies.

I is essential to study the signal flow chart carefully. This will help to isolate problems in the ClubMix. If you
follow the signal from input to output jacks it is possible to locate a fault.
If a fault is located, inform your dealer or us and we will assist you by phone. If this will not help return the
channel or master to your dealer, or the factory and we will be happy to repair it within 24 hours. Many faults
can be found by logical thinking and replacing integrated circuits, which is very easy. They are all socketed .
