PowerH SERIES

1.4 Features and Description

The power amp H2500/H5000 is part of Dynacord's new PowerH SERIES, which marks a milestone in the
design and the production of high-performance power amplifiers. The innovative 3-stage Grounded Bridge
Class H Topology with "floating" switching power supply unit offers very high and stable output with
extreme high efficiency on an extremely high performance level at minimum weight. PowerH amps are
ideal for driving professional touring, high-end Concert-Sound and Pro-Sound applications.
Next to classical protections, this new design employs the multi-stage ATP system (Advanced Thermal
Protection) for the first time, which in most cases prevents the power amplifier from switching off when the
temperature exceeds a critical level. The newly designed MCS system (Mains Current Supervision)
prevents power amplifier breakdown caused by the activation of the automatic circuit breaker.
For this, among other things, the MCS system uses the highly precise measurement of the RMS value of
the actual mains current consumption. Information about the status of the power amplifier and its internal
protections is provided on a LC-display. By utilizing the optionally available remote control module that is
compatible with IRIS-Net™, this power amplifier additionally offers comprehensive remote monitoring and
remote control functions plus a universal 2-channel digital audio controller (DSP) including highly precise
FIR-filtering and digital speaker protection algorithms.

1.5 Responsibility of the User

Speaker System Damage
PowerH power amps provide extremely high power output that might be dangerous for human beings as
well as for the connected speaker systems. High output voltages can damage or even destroy the
connected speaker systems, especially, when the PowerH amplifier is operated in bridged mode. Prior to
connecting any loudspeakers, make sure to check the speaker system's specifications for continuous and
peak power handling capacities. Even if amplification has been reduced through lowering the input level
controls on the amplifier's front panel, it is still possible to achieve full power output with a sufficiently high
input signal.
Dangers at the Loudspeaker/Power Outputs
PowerH amplifiers are capable of producing dangerously high voltage output that is present at the output
connectors. To protect yourself from electric shock, do not touch any blank speaker cables during
operation of the power amp.
HF-Interference
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection agains harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or televsion reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
