Bosch Releases New Version of IRIS-Net

Bosch Security Systems released the latest version of its IRIS-Net PA control software, which includes new features in the areas of flexibility, performance, configuration, control, and monitoring.

Bosch Security Systems released the latest version of its IRIS-Net PA control software, which includes new features in the areas of flexibility, performance, configuration, control, and monitoring, according to the company.

The new software release expands functionality for the Electro-Voice NetMax N8000 Digital Matrix Controller Task Engine by adding new logic blocks, such as delay, timer, and debounce, as well as functions for controlling Electro-Voice RCM-810 modules.

Bosch official say the addition add greater flexibility when programming complex logic sequences for customer applications. The inclusion of the RCM-810 functions allows a user to configure the GPIs and GPOs of the RCM-810 module to interact with the logic functions of the NetMax Task Engine, making it possible to expand the existing GPI-/O ports on the N8000 hardware for remote digital control interface, the company says.

Another new feature is the inclusion of a new speaker protection algorithm for RCM-26 and Tour Grade Series amplifiers. According to the company, the Thermal Energy Protection and Management (TEMP) Limiter is an advanced DSP algorithm that is able to calculate and track the voice coil temperature and apply specific gain reduction as needed to maintain the temperature of the components within safe margins. This method differs from applying RMS limiting or peak limiting, because it is a dynamic behavior that has been tailored to how the program material, DSP, and amplifier interact with the transducer components, as opposed to applying a set of control rules to the drive level based on the electronics, the company adds.

The TEMP Limiter works with the specific characteristics of the transducers it drives based on a behavior model derived from specific transducer characteristics and parameters measured and created by Electro-Voice loudspeaker engineering, company officials explain. The combination of the TEMP Limiter with the existing Peak Anticipation (PA) Limiter completes the loudspeaker protection package.

Bosch officials say that because the TEMP Limiter replaces the Compressor output channel, old projects using the Compressor parameter should be checked for proper function, because the parameter will be removed after update. Projects created with IRIS-Net v2.3.0 can't be used with RCM-26 devices with old firmware; however, projects created with the Project Generator are not affected by this change and can be used with IRIS-Net v2.3.0.

Other new features for use with NetMax include an Analog Delay block, Calendar Entry block, the ability to use common CobraNet parameters as I/Os, reduced DSP cycles for EQs of N8000 with more than eight bands, and supervision of RCM-810 remote amplifiers using N8000.
