CAL INSTALLATION OVERVIEW output level — up to a maximum peak SPL of 106 dB at Below is a basic overview for installing and using the CAL 90 meters with CAL 96 — over an operating frequency range loudspeaker. It is recommended that you read the remainder of 100 Hz to 16 kHz.
Blue = neutral AC INPUT CONNECTOR Brown = hot CAL receives AC power from its 3-pole powerCON 20 lock- ing connector. Located on the unit’s rear panel, the connec- tor is rated at 20 A and provides locking connections to avoid accidental disconnections.
1. Audio output is muted. If CAL shuts down due to either low or high voltage, its power supply automatically powers up again after three sec- 2. Voltage is detected and the power supply mode is auto- onds, so long as the voltage has returned to its normal oper- matically adjusted as necessary.

CAL Factory Presets Override and Mute A summary of the beam settings for the CAL factory presets is shown in Table 2. CAL ships from the factory with these Override presets loaded into the loudspeaker. The presets can be Mute edited and overwritten with the Compass control software.
USER PANEL COVER dard computer Ethernet port, network router, or network A user panel cover is included with CAL to protect the con- switch with a CAT-5e cable. CAL’s Network / AVB ports are nectors from dust in indoor installations and the weather AVB-enabled and use the IPv6 protocol for network commu- elements in outdoor installations.
