PRODUCT DESCRIPTION
The PWR-DSP3 answers the needs for a high power yet high quality plate amplifier module. Based on the synergetic
and innovative technology from DSP4YOU and PASCAL Audio, the module is a turnkey solution for multi-way
powered speakers. Third generation Class-D amplification, Digital Signal Processing (DSP) and the Audio Video
Bridging (AVB) are just examples of the embedded technology of this breakthrough product. With an impressive
maximum rating of 2400W (ch1) and 700W (ch2&3), be sure to find no compromise on audio quality from studio/ Hifi
systems to Pro-A/V applications.
Last but not least, the optional Audio Video Bridging (AVB) allows streaming of multiple uncompressed, low latency
and synchronized audio channels over Ethernet networks. Extended cable length, noise immunity and flexible routing
are some of the many obvious advantages of AVB. With our live amplifier health monitoring (load, temperature, clip),
live changes of the DSP settings and ZeroConf support, the PWR-DSP3 is a true Plug&Play device easily configured
over Ethernet or Wifi networks: A setup summarized by three words: Plug, discover, control.

Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon
them or against them, paying particular attention to cords and plugs, and the point where they exit from the
Amplifier Unit.
Lightning
For added protection of the product during lightning storms, or when it is left unattended and unused for long periods
of time, unplug it from the wall outlet. This will prevent damage to the product due to lightning and power-line surges.
Disconnection from the mains power supply can only be achieved by removing the plug from the mains socket and
by external disconnection of all poles from the mains.
Interference of external objects and/or liquids with the appliance
Never push objects of any kind into this product through openings as they may touch dangerous voltage points or
short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the amplifier.
Accessories
Do not place this product on an unstable cart, stand, tripod, bracket, or table. The product may fall, causing serious
injury, and serious damage to the product. Any mounting of the product should follow the manufacturer’s instructions,
and should use a mounting accessory recommended by the manufacturer.
Connecting
When you connect the Amplifier Unit to other equipment, turn off the power and unplug all of the equipment from
the supply source. Failure to do so may cause an electric shock and serious personal injury. Read the user's manual of
the other equipment carefully and follow the instructions when making the connections.
Sound Volume
Reduce the volume to minimum before you turn on the amplifier to prevent sudden high levels of noise which may
cause hearing or speaker damage.
Output connectors
WARNING: Output connector marked with the lightning flashes indicate high voltages that are potentially
life threatening. Wiring to these terminals requires installation by an instructed person and the use of readymade leads or cords. Custom wiring should only be carried out by qualified personnel.
To prevent electric shock, do not operate the product with any of the conductor portion of the speaker wire
exposed.
NOTE: For reasons of safety and performance, use only high-quality fully insulated speaker cables of stranded copper
wire. Use the largest wire size that is economically and physically practical, and make sure the cables are no longer
than necessary.
Precautions when connecting to MAINS IN and MAINS LINK
When mounting or connecting the product always disconnect it from mains. Only connect the product to an
appropriate AC circuit and outlet, according to the requirements indicated on the rating plate.
If a power cut occurs while the amplifier is switched on, it will restart automatically once the power supply has been
restored. All settings prior to the loss of power will be maintained.
IMPORTANT: Always connect the Product to mains through the MAINS IN connector on the Amplifier Unit.
IMPORTANT: Always use ready-made mains cables with original POWERCON connectors when connecting the
product to mains.
IMPORTANT: When disconnecting the Product from the mains, always disconnect at the mains end first, before
disconnecting the powerCon connector at the Product end.
IMPORTANT: Only connect additional Products to the MAINS LINK connector keeping within the specified power
rating. Always use ready-made mains link cables with original POWERCON connectors.
DO NOT REMOVE MAINS CONNECTOR GROUND, IT IS ILLEGAL AND DANGEROUS.

2. LINK OUT on PowerCON 20AMP connector (NAC3FCB) for linking to another amplifier within limits of your AC circuit.
The powerCON is a locking 3 conductor equipment AC connector with contacts for line, neutral and pre-mating
ground contact. It replaces appliance couplers wherever a very rugged solution in combination with a locking
device is needed in order to guarantee a safe power connection. Connector is to be purchased separately
.

2.4 Feature description
2.4.1 PWR-DSP3 Amplifier specifications
The PWR-DSP3 is an amplifier with total of 2400W limit by its power supply. The following electrical specifications show
the typical operating
Thermal specifications
NOTE: Channel 2 and 3 of the amplifier are single Ended amplifier designs which can pump back energy on the
power supply. At low frequencies this can cause asymmetrical power supply voltage rails, resulting in premature
clipping of the amplifier outputs or over-voltage protection of the power supply. When channel 2 and 3 are used to
amplify low frequency signals E.G with monitors, please take following actions.
Input for channel 2 should be inverted inside the DSP. This will cancel the supply pumping between channel 2 and 3.
In order to have outputs of channel 2 and channel 3 in phase, the output of channel 2 should be phase inverted by
interchanging the + and – connections for the speaker. Please see drawing below.
