Quantum QP2000 Series of power amplifiers are the latest generation of power packs that had been developed
through years of experience, countless feedbacks and limitless fine tuning of its predecessors, thus offering a
new and unique audio amplification product.
QP2000 series are available in the power range of 125, 250, 275 and 500W 100V line ratings with 2 hu height.
Control parts had been made contemporary with digital settings via front panel or through custom built software.
Various and known protection features are incorporated such as auto fault sensing (AFS), in built standby
amplifier changeover, temperature sensing and many more.
You shall be very certain that this is the final product you would ever search. We make it available without you
paying high price for a premium product that works exceeding your expectation.

5. RS485 DATA LINK
RS485 data port for parameter reading or controls from PC or external triggering panel. For PC link, a USB-RS485
converter shall be required whereas the software is available free.
6. AMP. FAULT CONTACT
A dry contact shall be available if the amplifier is detected as faulty. This allows activation of external changeover or
enable external notification panel.
7. AUDIO INPUT SIGNAL
The amplifier accepts line balanced audio signal and a link XLR connector is available to connect in parallel to the next
amplifier.
8. VENTILATION FAN
It is a variable speed temperature dependant fan with air blows from inside out. The fan can be set to auto or always
on mode. See “Setting Up the Unit” in the following sections.
9. AC MAINS INPUT
Operating voltage is 220 to 240V ac ; 50 hertz. Use suitable fuse for replacement.
10. DC INPUT TERMINAL
24V DC back up supply from batteries are connected to these connectors. Use suitable cable size to avoid overheat-
ing of cables.
11. AUDIO LINE OUTPUTS
Outputs from the units are available in 100 / 70V line and also for 4 Ohm speakers.At any one time, connect only one
terminal.
12. STANDBY AMPLIFIER CONNECTOR
QP2000 series are equipped with Auto Fault Sensing feature with Standby Fault Changeover relay incorporated.
Outputs from a standby unit is connected to these terminals and connected to the next duty pack in series. Please
refer to the section “ Connecting Standby Amplifier ”.

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

note on the link

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.
