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
