INSTALLATION
The LRF-04 must be installed by a qualified person or firm, according to existing regulations
(ministerial order no. 21712 issued by the Spanish Development Ministry, dated 26/10/1999
for Spain). If not, the guarantee is annulled and
will not be responsible for either
the malfunction of the unit or for any damage directly or indirectly caused to other units
connected to the LRF-04.
The LRF-04 is correctly installed by following these steps:
2.1 Connecting the LRF-04
In order for the LRF-04 to cover the entire sound chain, it must be inserted into the
reproduction chain between the mixing desk and the crossover (see diagram). The back
panel of the LRF-04 features symmetrical (XLR or Cannon connector) and non-symmetrical
(RCA connector) inputs and outputs.
It is vitally important to make sure that the electrical installation to which both the LRF-04 and
the equipment forming the reproduction chain are connected is earthed and complies with
low-tension regulations currently in force.
2.2 Placing and connecting the sensor
The sensor is placed on the ceiling of the establishment at a point equidistant from the
speakers, using the drills provided. Once the sensor has been placed, it is connected to the
LRF-04 by the connecting cable also provided. Should you need a longer cable than the one
provided, get in touch with any official
distributor. Once the sensor has been
connected to the LRF-04, the lid is screwed in place.
