QP2000 | Quantum Series Power Amplifiers
General Schematic Diagram
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
contact us for further details.
Application of PC monitoring of
amplifiers is optional.

In PC monitoring, each
power pack must be
addressed. Up to a max of 16
nos of power packs can be
monitored.
To avoid signal distortion in
looping the audio, usage of
signal distributor (DA2208) is
strongly recommended
