Power Consideration for 30W Models

T-7707BM, T-7707M, and T-7707DH feature 2x30W amplifiers. For maximum output, use the optional 24V DC power adapter. PoE (802.3af) can deliver approximately 15W per channel – sufficient for most applications. For full 30W, DC adapter is recommended.

Wireless Mic Range

The 2.4GHz wireless microphone system provides up to 30m range in open areas. In classrooms with walls and obstacles, typical range is 15-20m – sufficient for most teaching environments. Multiple receivers can be used in adjacent rooms without interference.

Typical Classroom Installation
