Advantages of a using the Fire 92 line array:
Studiomaster Professional Fire 92 has several advantages over the horizontally stacked speaker systems normally used for covering large
events. These are:
•
Higher direct to reverberant ratio due to directional nature of the system and therefore better intelligibility.
•
Increased feedback rejection due to increased directionality in vertical plane and therefore more acoustic gain available.
•
Frequency response is uniform over the coverage area.
•
Because of increased HF throw of the system, need for delay stacks is eliminated or reduced.
•
Even sound pressure level can be achieved over the entire listening area by proper articulation of the vertical array formed by Fire 92.
•
More stage space available as Fire 92 arrays are flown.
The Fire 92 system can be configured in any of the following vertical formations:
•
Straight Array - all modules are without tilt.
•
Curved Array - upper modules are curved up towards ceiling and lower ones are curved down.
•
J Array - upper modules are without any tilt and lower ones are curved down.
•
Spiral Array - The topmost module/ modules is/ are without tilt and the subsequent modules have increasing tilt with the lowest having
maximum tilt with varying splay angles 3

WARNING: To prevent risk of electric shock, do not connect the speaker with the amplifier
switched on. Before using the speaker, make sure that all connections are made correctly
to prevent accidental short circuit from giving rise to electric sparks.
Speakon Connectors:
There are two Speakon connectors. One socket is used for audio signal input from amplifier output and other
socket can be used as output for parallel connection of another speaker.
HF Switch:
HF switch is used to long throw or short throw on the application. In HI position HF is increased by about 2dB compared LO
position.
