Pros & Cons
👍 Pros
- This Williams Sound WIR TX90 offers both a two-channel integrated modulator and emitter, streamlining setup for hearing assistance systems.
- It supports multiple frequencies (2.3/2.8/3.3/3.8 MHz), allowing flexibility in channel selection and reducing interference.
- The inclusion of a TFP 010 Power supply means it comes with the necessary power component right out of the box.
- A BKT 024 wall/ceiling mount is provided, facilitating flexible installation options in various environments.
- The WCA 079 50 ft. power cable offers ample length for positioning the transmitter optimally within a space.
👎 Cons
- As an infrared (IR) system, line-of-sight is required between the emitter and the receiver, which can be obstructed by objects or walls.
- The specified frequencies are within the IR spectrum, which might be susceptible to interference from strong ambient light sources or other IR devices.
- While the 50 ft. power cable is generous, larger venues might require additional cable extensions or power sources.
- The system is designed specifically for hearing assistance, limiting its versatility for broader audio transmission applications.
- The two-channel limit may not be sufficient for environments requiring multiple language feeds or complex audio routing.
