Detailed Description Up 3
Up 3 is a compact ceiling loudspeaker for background music and speech in commercial spaces. A single 3-inch full-range driver provides 130° conical coverage. The steel back can and integrated mounting hardware form a complete ceiling-installation assembly.

The speaker handles 20 W AES and can operate on an 8 Ω amplifier channel or a 70 V or 100 V distributed line. Transformer taps are selected using the rotary control behind the removable grille. The datasheet specifies a response of 95 Hz–15 kHz within ±3 dB when used with the stated preset.
Grille 1 provides an optional bezel-less appearance, while Pendant 1 adapts Up 3 for a suspended installation. Select the amplifier and loudspeaker preset for the chosen operating mode, including the recommended high-pass filter. The specification table gives the ceiling opening, mounting dimensions and supplied installation accessories.
