3 Product Summary The Meyer SB-1 Parabolic Sound Beam is the first device that propagates sound waves with SPLs that decrease as little as 3 d B per doubling of distance for more than 300 ft, across a five-octave frequency range, with a consistent and narrow beam width.
4 The minimum electrical service amperage required by a system of SB-1s is the sum of the maximum continuous RMS current for each speaker . We recommend allowing an additional 30% above the minimum amperage to pre- vent peak voltage drops at the service entry .
5 AC T roubleshooting If the Active lamp does not light after connection to an AC source for three seconds, the problem is probably in the power supply . In the unlikely case that the circuit breakers trip (the white center buttons pop out), the amplifier or power supply may be malfunctioning.
6 Fans and Cooling System The SB-1 uses a forced-air cooling system with two fans to prevent the amplifiers from overheating. A variable -speed primary fan runs continuously with an inaudible operating noise of 22 dBA at 1 m at its slowest speed. The speed of the primary fan begins increasing when the temperature of the heatsinks reaches 42°C.
7 Lay the positioning yoke on the ground so that the hole closest to the front of the yoke is aligned with the 3 / 4 ” threaded rigging hole on both sides of the SB-1 . Place the split washer on the 3 / 4 ” grade rigging bolt and then place the flat washer on top of split washer so that the split washer is closest to the bolt head.
8 Cover Removal and Installation The Dish cover is held in place by four sets of C-brackets and locking pins as shown below . It is easier to remove the dish cover if the pins and brackets are not supporting the entire weight of the cover .
9 While keeping a firm grip on the pod insert one of the legs into a c-bracket so that the holes in the legs are aligned with the holes in the c-bracket. Then insert a pin through the holes while pressing down on its button head. When the first pin is in position attach the leg opposite to the first one.
10 • T o r educe the risk of electric shock, disconnect the loud- speaker from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the loudspeaker to a two-pole, three wire grounding mains receptacle.
