Built for Distributed Audio Systems
The ITC T-105 100V ceiling speaker is designed for distributed audio installations where multiple speakers may be installed throughout a building.
Its integrated 70V/100V transformer makes it suitable for commercial PA systems and helps simplify multi-speaker installations. The transformer-based system can reduce line losses over longer cable distances and allows multiple loudspeakers to be connected in parallel.
Selectable Power for Flexible Installation
The T-105 provides three selectable power levels at 100V:
1.5W / 3W / 6W
For 70V systems, the available taps are:
0.75W / 1.5W / 3W
This allows installers to select the appropriate output level according to the room size, speaker quantity and ambient noise requirements.
Clean In-Ceiling Design
The speaker is designed to sit inside the ceiling rather than taking up wall or floor space. Its white grille and compact profile provide a discreet appearance suitable for offices, corridors, classrooms, hotels and commercial spaces.
