Answer:
The SBS-40 is the 40-channel configuration in the Hitune Bass SBS modular series. Larger facilities requiring greater room capacity use the higher-channel siblings: the SBS-60 (60 channels), SBS-80 (80 channels), or SBS-100 (100 channels).
Hitune Bass manufactures the SBS school broadcasting platform across multiple channel increments to align with differing institutional scales. The SBS-40 shares identical two-way talkback, All Call capability, dual 230V AC / 12V DC power architecture, and chassis materials with its sibling models, differing primarily in switching channel capacity:
- SBS-40: 40 selective room channels (recommended for schools, colleges, or departments with up to 40 instructional zones).
- SBS-60: 60 selective room channels.
- SBS-80: 80 selective room channels.
- SBS-100: 100 selective room channels for extensive multi-building or multi-wing commercial installations.
