Dynacord Professional Power Amplifiers manual

PowerH Series

circuits at the output of the power amplifier are detected early on, even at low levels. The protective circuit is activated and a report on the fault in question appears simulta- neously on the front display. In the event of excessive high-frequency overload, there is an automatic level reduction to protect the power amplifier itself and also the loud- speaker components connected.

The large, background-lit 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 performance. The THD,

intermodulation distortion (IMD- SMPTE) and dynamic intermodulation (DIM) are well below 0.05% and therefore well 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 conti- nuously (H 5000), thereby allowing the power amplifier to operate

as a stable voltage source even with extremely low loads. PowerH power amplifiers therefore have a significant amount of headroom at their disposal, which results in superlative dynamics even with low loads.

PowerH power amplifiers leave nothing to be desired in terms of connectivity. For the inputs, XLR IN/parallel OUT sockets are provided along with additional Phoenix connectors. The input sensitivity is switchable between 0dBu, +6dBu

and 32dB Constant Gain. In addition, there are switches for Bridged Mode and Parallel / Dual as well, naturally, as 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. The signal of Output B is additionally available on pins ±2 of Output A, so that with

4-pin wiring a two-way system can be driven. Parallel to these, additio- nal binding posts are provided. In terms of connectivity, therefore, PowerH power amplifiers satisfy all the demands of both mobile applications and pro audio fixed installations.
