"This new system represents a big improvement over the 15-year-old version it replaced," says Charles Cassell of Audio-Video Group. "We've all been quite pleased with the sonic upgrade in every aspect of reinforcement at services and other events held in the sanctuary." Four Inter-M power amplifiers (two model L1800 and two model L2400) are rack-mounted with the system's dbx DriveRack digital processor in an adjacent equipment room. They drive the system's six D.A.S. Audio DS8 full-range loudspeakers flown above three seating sections, with two loudspeakers providing dedicated coverage to each section. In addition, one of the L2400 channels is dedicated to a single D.A.S. Audio 18F 18"-loaded subwoofer.
"The price point is one of the attractive aspects of the Inter-M amplifier line, where you can get a lot of performance at a very competitive cost," notes Cassell. "However, we were also attracted to these amplifiers because of their low rate of AC power consumption. This was a situation where available power was limited, so it was important that the new system not overload the building's electrical system."
Other features of Inter-M's L Series amplifiers include a 2-ohm-load stable design, selectable high-pass filtering on each channel, clip limiter circuitry and forced air cooling.
