Dynacord PowerH Series specs

Dynacord power amplifiers are known for their absolute reliability under the most arduous of conditions on the road. In addition to the legendary manufacturing quality that comes with the 'Made in Germany' label, the comprehensive set of protective circuits

plays an important role here: an integrated micro-controller co-ordinates proven protections against short-circuit, HF or DC at the output, back EMF, overheating and open-circuit opera- tion, the power-up current limitation and dynamic audio limiters, as well as making additional new and highly intelligent protective functions possible: for example, the temperature in the power amplifiers is monitored at no fewer than six different points and the front-to-rear ven- tilators controlled accordingly. Under abnormal thermal 'worst case' conditions, the CPU acti- vates a voltage limiter or gain reduction depending upon the requirements of the situation, so as to prevent a thermal shutdown of the power amplifiers. All corrective measures are indi- cated on the front panel and spelt out clearly on the liquid crystal display. In addition, a report is created making it possible to enquire later as to all such 'interventions', each of which is time-stamped.

The mains voltage is monitored and displayed continuously, with the devices adapting auto- matically to 230 V, for example, or 120 V. At the same time, the mains current consumption is also monitored and displayed.The user can adjust, via the front panel display, the threshold value of the automatic circuit breakers. In the event of possibly overloading the mains, the amount of amplification is reduced to prevent the circuit breakers tripping. Any short-circuits at the output of the power amplifier are detected early on, even at low levels. The protecti- ve circuit is activated and the error report in question appears simultaneously on the front dis- play. In the event of excessive high-frequency overload, there is an automatic level reduction to protect the power amplifier itself and also the loudspeaker components connected.

The large, backlit liquid crystal display delivers comprehensive status information, error reports and measurements as well as allowing you to control the basic

settings and (with the IRIS-Net™module integrated) select presets as well.

In addition to extreme reliability and forward-looking operating security, the PowerH power amplifiers are impressive for their outstanding audio perfor- mance. The THD, intermodulation distortion (IMD-SMPTE) and dynamic intermodu- lation (DIM) are all well below 0.05% and therefore far below the limit of audibility. All the components of the switching power supply are so safely dimensioned that they are capable of delivering the maximum peak output current of 70 A continuous- ly, thereby allowing the power amplifier to operate as a stable voltage source even at extremely low loads. PowerH power amplifiers therefore have a significant amount of

headroom at their disposal, which results in superior dynamics even at low loads.

PowerH power amplifiers leave nothing to be desired in the way of connectors. For the inputs, XLR IN/parallel OUT sockets are provided along with additional Phoenix connectors. The input sensitivity is selectable between 0 dBu, +6 dBu and 32 dB Constant Gain. In addition, there are switches for bridged operation

and parallel / dual as well and, naturally, a Ground Lift switch.

A latching PowerCon connector is provided for the mains power line, which prevents the plug being yanked out accidentally. The power outputs are implemented as Speakon sockets with parallel binding posts. In terms of connectivity, therefore, PowerH power amplifiers satisfy all the demands of both mobile applications and pro audio fixed installations.

PowerH Series specifications
