Hera, will not only log the average and peak RMS sound pressure level over a time period, but Hera will also detect and log attempts of system tampering (for example disconnection of the microphone). The logs can be easily consulted by any user directly from the front panel or retrieved on a computer and printed out.

Hera also offers two logic outputs that may be used to control external devices or mains cut-off if a certain threshold is being exceeded. This threshold value may be scheduled to allow for different sound levels at set times.

All settings are pin code protected and can easily be set from the devices' front panel. Apex Hera is delivered with a measurement microphone and this is factory calibrated for perfect accuracy.

Hera also offers an automatic calibration function for remote microphone distance compensation. This is imperative in most venues, since the measurement microphones should be placed out of reach.

Optionally you can connect the Apex Leto large remote display to the Hera so that the audience, band or DJ may have visual sight on the sound pressure levels at any time.

The Hera may be used together with the Apex Argos sound level limiter. The Argos will then be slaved onto the Hera's measurement and threshold. Use the Hera together with the Apex Argos, they will be your neighbours dream team!
