Digital remote inclinometer – with a remote sensor in the bumper and a meter unit at ground level to ensure
precise aiming of the cluster. A typical unit for this purpose is the Schaevitz Anglestar.
Audio Analysis Software – strongly recommended but perhaps not absolutely essential. SDA EASERA, or SIA
SmaartLive, SmaartPro or Spectrafoo enable rapid and detailed analysis of the acoustical performance. EASERA
and SmaartLive offer the additional benefit of enabling you to adjust FOH EQ on the D26 Digital Controller while
observing the results in a dual-FFT window on your laptop. Consider taking a training course in using one of
these tools if you are not already competent with them – it will pay dividends in increased performance and in
your general knowledge of the principles underlying sound reinforcement.
Testing and Maintenance
Transducers:
Your Renkus-Heinz Line Array system is a precision piece of equipment that needs periodic maintenance in order
to give long and reliable service. We recommend regular testing of all cone, compression and CoEntrant drivers,
preferably using a suitable test rig and process testing software or at least a sine wave generator and careful
listening test coupled with a visual inspection.
Hardware:
There are several critical points in the cabinets. Of primary concern are:
a) The machine screws attaching the enclosure to the flying hardware
b) The screws attaching the field-replaceable horn flare to the front of the enclosure (STLA & STXLA only)
These fasteners should be regularly checked and tightened as necessary.
Cleaning:
The exterior of the cabinet and the rigging system can be cleaned with a damp cloth soaked in mild soapy water.
On no account use solvent-based cleansers , which may damage the finish of the cabinet. After cleaning, the
rigging system must be treated with a suitable lubricant (such as Scottoil FS365, a water-based lubricant with a
mixture of machine oil, surfactant and anti-rust treatment) to prevent rusting.
