CAL Column Array Loudspeakers

The loudspeaker shall be a self-contained, steerable, column array system with discrete array modules, each comprised of two 4-inch cone drivers, six 20-mm tweeters, and multiple class D amplifier channels. Onboard processing shall include 5-band parametric EQ, delay, and gain.

Horizontal coverage shall be 120 degrees. Vertical spread shall be variable from 5 to 30 degrees in 5-degree increments. Vertical beam steering shall be from ±30 degrees in 1-degree increments.

Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating frequency range, 100 Hz to 16 kHz; frequency response, 105 Hz to 15 kHz ±4 dB; phase response, 230 Hz to 16.9 Hz ±45 degrees.

Three Phoenix 6-pin male connectors shall be included for balanced analog audio input and loop output. Audio input shall be electronically balanced with a 10 kOhm impedance
and accept a nominal 0 dBV (1.0 V rms) signal. An additional Phoenix 6-pin male connector shall be included for AES/EBU digital input. An AVB-enabled Ethernet port shall
be included for input from digital audio streams.

Power requirements shall be nominal 100, 110, or 230 V AC line current at 50 to 60 Hz. UL and CE operating voltage range shall be 100 to 240 V AC. The AC power connector shall be powerCON 20.

The loudspeaker shall include two control ports: one Phoenix 6-pin male connector for selecting onboard presets and reporting loudspeaker faults; and one Phoenix 5-pin male connector for triggering emergency mute and input override.

The two Ethernet ports shall provide computer control of the loudspeaker via Meyer Sound’s Compass control software. The Compass control software shall also include RMS remote monitoring of loudspeaker performance parameters.

Loudspeaker components shall be mounted in an extruded aluminum enclosure available in white, black, and custom colors. Weather protection and a user panel cover shall be included for outdoor installations. Brackets shall be included for fixed mounting on walls and columns.

The loudspeakers shall be the Meyer Sound CAL 96, CAL 64, and CAL 32.
