rCM-26
SUPERVISION AND DIAGNOSIS
The RCM-26 transmits all relevant amplifier data to
the IRIS-Net user interface, supervising the operating
status of the power amplifiers, the temperature in the
power blocks and in the power supply, voltages and
currents at the outputs, all protections, the mains
voltage and current consumption, pilot tone and network
status.
The impedance measurement with a 20Hz to 20 kHz
sine wave sweep and the comparison with the stored
reference data make it possible to diagnose with precision
the condition of the connected loudspeakers and
even of their individual components and cable connec-
tions. Problems are therefore detected early and the
system is able to respond in good time.
It is even easy to examine the state of loudspeakers
that are difficult to access, such as those in stadiums
or large entertainment venues. The System Check
function allows you to measure comprehensively,
and conduct a full examination of, a very large audio
system at the push of a button.
Even in live performance, the connected load is moni-
tored continuously. Any undershooting (short-circuit)
or overshooting (interruption) of the set tolerance
limits is automatically detected and reported imme-
diately.
FIR FILTERS
Although FIR filters require a massive amount of proces-
sing and are complex, they are realized in the RCM-26 in
addition to the classical filtering and signal processing
functions. Both linear-phase FIR filters and ‚zero latency‘
FIR filters, which add no further delay to the time signals
take to pass through the device, are available.
Users can create their own linear phase ‚brick-wall
X-over‘ and edit them in real time. For DYNACORD
