Note :

Changeover :

Duty amplifier with higher priority for changeover must be placed nearest to the standby unit. ie. first output

connection from standby amplifier must be connected to this unit.

Standby fault changeover only available at 100V line outputs. Thereby to utilise this feature, speaker

connections must be terminated at 100V output terminals.

If the system consists of various ratings of power amplifiers, always allocate standby unit with the highest

power rating, to avoid overloading in the event that changeover takes place.

An example of application with

single source to amplifiers, with

one unit being a standby unit.

For Uninterrupted Paging System

or Matrix application, please

Application of PC monitoring of

amplifiers is optional.

In PC monitoring, each

power pack must be

addressed.Up toa maxof 16

nos of power packs can be

monitored.

To avoid signal distortion in

looping the audio, usage of

signal distributor (DA2208) is

strongly recommended

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.
