Detailed Description Up 4O
Up 4O is a 4-inch ceiling loudspeaker supplied without a back can for installations where cavity depth is limited. Its full-range driver provides 130° conical coverage for background music and speech. An integral fixing system secures the speaker in the ceiling.

This model is designed for 70 V and 100 V distributed systems, with the selected transformer tap determining its load. The rated power is 10 W AES. Its published response with the specified preset is 87 Hz–15 kHz within ±3 dB, with the recommended high-pass setting listed in the technical table.
The tap selector sits behind the removable grille. Grille 1 is available when a bezel-less finish is required. Check the cut-out and mounting depth for the chosen ceiling, and use the listed processing settings when matching the speaker to the system amplifier.
