INSTRUCTION MANUAL
Thank you for choosing another quality product from Amperes Electronics.
DP2000 Series are the new models of amplifiers which had been further refined to meet the market demands. DP2406 is
a quad channel version with 60W 100V output per channel whereas DP2212 shall be dual channel with output capacity of
120W 100V per channel.
Class D power engine is the core driver of the DP2000 series, which has various advantages over conventional circuitries,
among them are the higher amplification efficiency thus emitting lesser heat and current draw, flatter frequency response
and able to withstand higher operating temperature while maintaining its amplification characteristics.
It is most suitable for application in Matrix paging setup, where multiple channels of amplifiers are required. In system
which has small load for each channel, DP2000 amplifiers shall be the right choice as the unit count shall be greatly
reduced, which translates into rack space savings.

1. CHANNEL 1, 2, 3 & 4 INDICATION LEDs
Mains LED for incoming mains supply & protect LED is to indicate if the unit is switched to protection mode. Clip
LED shall lit if the incoming signal is too high whereas others to indicate signal level in two level i.e. -40 dB &
-10 dB.
2. MAINS SWITCH
For switching mains ac supply and the corresponding LED shall lit accordingly. Mains LED shall not lit if the back
up DC supply is available.
3. MAINS AC CORD
Mains AC cord comes with standard British 3 pin plug with fuse rating of 5A.
4. DC 24V INPUT
The unit operates on 24V DC. It is preferred that the unit to be supplied directly from the uninterrupted power
source. ie: Back up batteries. Alternatively, connect it to regulated power supply unit which is in turned has back
up supply.
5. SPEAKER OUTPUT TERMINAL ( CHANNEL 1, 2, 3 & 4 )
Outgoing terminals to speakers available in 4 Ohm, 70 and 100V line for usage with transformer coupled
speakers. The total speakers combined should have impedance higher than stated in the corresponding output
terminals to avoid overloading.
Loudspeakers with suitable matching transformer can be connected to the 30 or 70 or 100V line outputs in
parallel. However the total load should not exceed the nominal power output rating of the amplifier.
Do not parallel two power amplifiers in order to gain higher power rating as this may cause overloading in the
event that any one of them failed.

The above diagram depicts the air flow pattern for amplifier cooling system. Cool air is pulled from the side vent holes and
warm air shall be dissipated via the continous rotating fan.
Please ensure these vent holes are not blocked in order to keep the operating temperature at optimum. Allow a breathing
space of 100 mm for each vent outlet.
For installation in rack, we recommend that internal rack ventilation fans are installed, one for cool air intake and the other
for heat dissipation.
The optimum operating temperature of the unit shall be kept at approximately 40 degree Celsius.
Application example using one duty amplifier with one standby unit connecting to two zones of speakers.
