Introduction
Foreword
Hera offers sound level monitoring and logging of events. As a
standalone unit it can be used as a cut-off device, as is required
by some authorities. Combined with the Argos the combined
units will act as a sound level controller with measurement and
logging function.
Hera, will not only log the average and peak RMS sound level
pressure over a time period, but Hera will also detect and log
the 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.
Dear customer,
Thank you for buying the Apex Hera.
Hera is a microprocessor based sound level controller. Hera can be used either as a standalone unit or combined
with the Apex Argos. Applications include noise level control in bar, theatre, concert venue,… as well as compliance
with Directive 2003/10/EC “Noise at work”.
Product highlights
• Factory calibrated for accurate measurement
• All settings may be made from the front panel and are
pin-code protected
• Two separated logic outputs for controlling external
devices and mains power cut relays, all set/reset times
are adjustable
• Average and peak RMS sound level logging over an
user adjustable time frame
• System tamper detection and logging
• 14-days sound level log (when measurements are
logged at 15 minute intervals)
• Ability to schedule multiple threshold parameters
covering any time or day of the week
• Easy computer log read-out through standard serial
port
• Optional remote large level display
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 deported
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. 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 !
