QtPro products quick comparison guide
This article offers a side by side comparison of the QtPro products currently available from Biamp. Consult the table below to review information on the number of emitters, zones, types of emitters, and other relevant details when considering how to design a space. At the bottom of the article, a link is provided for requesting a quote and more information on difficult to design areas.

Emitter spacing guide
All QtPro lines use Qt Emitters. Follow these guides when outlining the space where sound masking is required
| Ceiling / Mounting height | Emitter grid spacing |
|---|---|
| Less than 9' (2.7 m) | 8' x 8' (2.6 m x 2.6 m) |
| 9' to 12’ (2.7-3.6 m) | 10’ by 10’ (3 m x 3 m) |
| 12' & above (3.6 m +) | 12’ by 12’ (3.6 m x 3.6 m) |
For more information on laying out the emitters see our install guide here.
