CAL Specifications

ACOUSTICAL

Operating Frequency

Range

100 Hz – 16 kHz

Note: Recommended maximum operating frequency range. Response depends on loading condi-

tions and room acoustics.

Frequency Response 105 Hz – 15 kHz ±4 dB

Note: Measured free field with 1/3-octave frequency resolution at 4 meters.

Phase Response 230 Hz – 16.9 kHz ±45 °

Maximum Peak SPL CAL 96 At 90 m (295 ft), 106 dB peak

CAL 64 At 60 m (196 ft), 106 dB peak

CAL 32 At 30 m (98 ft), 106 dB peak

Note: Measured with single beam, 5-degree vertical spread, and no steering.

COVERAGE

Horizontal Coverage 120°

Vertical Beam Spread Variable, 5° to 30° in 5° increments

Vertical Beam Steering ±30° in 1° increments

Vertical Beam Splits CAL 96 Top split, bottom split

CAL 64 Center split

CAL 32 None

CROSSOVER

Crossover 2 kHz

Note: At this frequency, the transducers produce equal sound pressure levels.

TRANSDUCERS

Low-frequency and

high-frequency

CAL 96 (24) 4" cone drivers, (72) 20 mm tweeters

CAL 64 (16) 4" cone drivers, (48) 20 mm tweeters

CAL 32 (8) 4" cone drivers, (24) 20 mm tweeters

AUDIO / CONTROL

Analog Audio (3) Phoenix 6-pin male connectors for balanced audio input and loop output

Digital Audio (1) Phoenix 6-pin male connector for AES/EBU input

Note: The connector’s bottom three pins are not used.

Network / AVB (2) AVB-enabled Ethernet ports for audio streaming, and beam control and RMS monitoring via

Compass control software

Note: Second Ethernet port with provided for redundant control.

Processing Mute, gain, 5-band parametric EQ, and delay, stored in four onboard presets

Note: Processing and beam settings can be edited in Compass control software and saved in four

onboard presets.

Logic I/O Phoenix 6-pin male connector, recalls onboard presets, reports relay closures (and openings) for

fault reports; Phoenix 5-pin male connector, triggers emergency mute and input override

Display OLED button displays CAL's network addresses during startup or when the button is pushed

AMPLIFIER

Type Multichannel Class-D, one channel per driver
