BVRAMB Ambient Noise Sensors
Care should be taken in the positioning of the
BVRAMB
ambient noise sensors, they need to
be as close to the ambient noise source as possible, and as far away from the loudspeakers
as possible. Do not position them in the dispersion angle of the loudspeakers, or close to a
permanent noise source (air conditioning, fruit machines etc) In high ceiling rooms position
the sensor so that it closer to the floor than the ceiling
Cables should be 3-core fire rated, with a conductor cross sectional area of 1.0mm or
greater.
Two
BVRAMB
ambient noise sensors can be wired in parallel on the same circuit; a 4K7
compensation resistor is fitted at the
BVRCI
card. See following fig 1 for typical connection
details.
