Product description HK L.U.C.A.S Alpha MAX
For mobile sound reinforcement, subwoofers, tops and power amplifiers need to be matched without making setup unnecessarily complicated. The HK Audio L.U.C.A.S MAX System combines these components in an active 2.1 PA with integrated amplifier and controller electronics: a 15-inch subwoofer powers two satellites, which connect via Speakon.
The subwoofer houses a Class D amplifier delivering 1,200 W RMS for the bass and two more, each delivering 400 W RMS, for the satellites. The DDO™ system controller matches the signal processing to the speakers; multiband limiting and a subsonic filter are also part of the system electronics. Once you have set up and connected the system, you can use the designated controls and setups to adapt it to the application at hand.
Use the control panel to choose one of five sound presets: Speech lowers the subwoofer level for speech reinforcement, while Live 1 and Live 2 offer different emphases on bass and vocals. DJ 1 is tailored to CD playback, while DJ 2 also takes MP3 sources into account. A Mute setting is also available. Select presets using the Up/Down buttons; the display shows the configuration. A Gain control adjusts the input level, Balance changes the level ratio between left and right, and Subwoofer Level lets you adjust the bass relative to the satellites. The Ground switch can separate the signal ground from the chassis ground in the event of hum.
Two balanced XLR inputs are available for signal input, along with two parallel XLR outputs for routing the signal onward. The satellites connect to the two Speakon NL4 speaker outputs. According to the system specifications, the 15-inch neodymium woofer covers 40 to 130 Hz; each satellite features a 10-inch neodymium speaker and a 1-inch compression driver. The CD horn has a 60° x 40° dispersion pattern, and the passive crossover operates at 2.2 kHz with a slope of 12 dB per octave.
The satellites can be aimed at the audience using the 36 mm DuoTilt™ pole-mount flange, which offers two tilt angles of −7.5° or −15°. The subwoofer has an M20 threaded plate and comes with castors as standard. The castors make it easier to transport the 39 kg subwoofer; the two satellites weigh 11 kg each. The system weighs 61 kg in total.
With 2,000 W of total power, five presets and integrated signal processing, this active system is suitable for mobile DJ setups, live music and speech reinforcement. The matched combination of a subwoofer and two satellites is suited to events where you want to use a complete PA with clearly defined connection and setup options.
