Architect and Engineer Specification
The system shall be a multiple-driver, full-range portable loudspeaker system with internally-supplied power
amplification and active equalization for multiple operating modes as follows:
The transducer complement shall consist of 32,
curved articulated array loudspeaker, coupled with a modular 10" x 18" (254 mm x 457 mm) RaceTrack low-
frequency driver mounted in a ported bass enclosure. The loudspeaker array shall be wired in a series/parallel
configuration.
The nominal horizontal beamwidth of the loudspeaker shall be 180° and the nominal vertical coverage shall
be 0°. The system's power stand shall incorporate a ported venting system for the low-frequency driver. The
power amplification for transducers shall be supplied by an integral two-channel onboard amplifier providing
1000 W for low-frequency transducers (Sub2) and 480 W for high-mid array transducers (L1 Pro32).
The onboard digital mixer shall consist of three input channels. Channel 1 and 2 shall provide a combination
XLR or 1/4" TRS connector (mic/instrument/line) with treble, bass equalization, and reverb effects. Phantom
power (48 V) shall be available via a push button to enable and disable. Both channels shall provide selectable
equalization presets for microphone and instruments. Channel 3 shall provide a 1/8" TRS (stereo-summed,
line) connector, 1/4" TRS (line) connector. The same channel shall provide
high-definition AAC codec with a Bluetooth pairing button provided. All three channels shall have a dedicated
channel mute button. The output connector of the onboard mixer shall consist of one XLR balanced line-level
output connector. The onboard mixer shall provide a ToneMatch RJ-45 connector to receive digital audio and
send power via ToneMatch cable for Bose T4S/T8S ToneMatch mixer.
The enclosure of the power stand shall be constructed of high-impact polypropylene. The arrays shall be
constructed of high-impact ABS. The subwoofer shall be constructed of high-impact polypropylene and birch
plywood.
The system's array outer dimensions shall be 83.5" H × 13.8" W × 22.5" D (2120 mm × 351 mm × 573 mm). Its
net weight shall be 28.9 lbs (13.1 kg). The system's subwoofer dimensions shall be 27.3" H × 12.5" W × 21.7" D
