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.
