Note 1 :
Loop the audio signal to a maximum of 6 to avoid signal distortion. In case that more amplifiers are required in
the system, use a signal distribution amplifier.
Note 2 :
Always ensure cable size, particularly the incoming cable from battery is sufficient enough to cater for the load
during battery takeover when the mains failed. As a rule of thumb, a 2.5mm cable shall not be linked to more
than 6 power packs.
Note 3 :
AFS only applies to 100V line output. Should you decide to turn of the feature utilising the internal changeover
relay, always connect the output at 100V line terminals. At any one time, never use different outputs simultane-
ously.
Note 4 :
The amplifier that need to be accorded top priority for changeover should be connected first to the standby
amplifier output. If the changeover occurs at the first unit, the remaining shall not be provided with back up
output.
In order for changeover to take place, AFS feature must be turned on.
