Our latest release of ControlSpace Designer v5.13 introduces enhancements for PowerShareX amplifiers in commercial applications for larger crowds and or requiring third-party control and monitoring.
The audio system is mission-critical in delivering information to the entire audience. Businesses prioritize continuous operation and minimal downtime by implementing system health monitoring and a backup strategy that includes features like failovers or redundancies. The system autonomously monitors its health, and in the event of a primary device failure, a synchronized backup device seamlessly takes over until the issue is resolved.
This improves system reliability, minimizes the risk of disruptions, and guarantees a reliable and high-quality audio experience for the audience. Considering the expense of backing up devices in an audio system, attention is usually directed towards the components that undergo the most stress in the system, including audio cables, network infrastructure, power amplifiers, and loudspeakers.
ControlSpace Designer v5.13 also improves integration with third-party audio and control systems for integration into larger systems. PowerShareX functionality has been broadened to include enhanced health monitoring, backup strategy features, and improved integration with third-party systems. For a detailed exploration of these new features, watch our video series, where each enhancement is covered individually.
In the event of interruptions to the audio input source, PowerShareX will smoothly transition to the designated backup source, adhering to a four-level priority scheme.
The automatic input source failover feature empowers the system designer to program four levels of priority for each input. When an interruption occurs, PowerShareX will seamlessly failover to the second prioritized source. If no source is available, it will sequentially switch to the third and then the fourth prioritized source.
This feature enables you to actively monitor the frequency response of the impedance observed by the loudspeakers connected to the amplifier’s outputs.
A test signal is inserted into the output signal processing chain and used to measure the output load impedance and current from 20 Hz to 20 kHz.
When a loudspeaker cable is severed or becomes disconnected from the amplifier, a significantly higher impedance value would be measured. In contrast, measurements close to zero ohms would likely indicate an output short-circuit. In either case, a fault alarm is produced.
You can enhance loudspeaker system monitoring with three additional advanced alarms for each amplifier output.
The first is the Pilot Tone Voltage Alarm, which sends a pilot tone over the loudspeaker line and measures the voltage. If it exceeds the defined threshold, an alarm is triggered.
The second is the Pilot Tone Load Alarm. Similar to the voltage alarm, it measures load impedance instead of voltage and triggers an alarm when it falls outside the defined range.
The last monitoring feature is the Nominal Impedance Alarm, which stores a reference measurement for the nominal impedance of the loudspeaker load with a user-defined threshold. If the measured load falls outside the stored range, the device generates an alarm.
When an alarm is triggered, it activates alarm and fault indicators, as well as general-purpose outputs.
PowerShareX amplifiers now have improved digital sensitivity adjustments and an added analog trim setting to optimize your system’s gain structure.
