How many musicians can use this system simultaneously?
Up to 12 compatible channels per group with group and channel scan for easy set-up.
Why internal antennas?
For ideal signal strength, antennas on a wireless system need to be set up in a certain way. The internal antennas on the BLX receiver are already set in this ideal way, offering up to 100 m operating range and optimal signal strength.
Additionally internal antennas cannot be broken during setup, use or transport.
Is the setup really that easy?
Yes, with one button you can start the group and channel scan, which gives you the best open frequency. Adjust the transmitter to the same channel and you’re ready to go.
What does “Linearity” mean?
The proportion between input signal of the transmitter and output signal of the receiver is always constant.
How does the BLX receiver perform compared to wired?
The frequency response of the wireless microphone is almost identical to the frequency response of a wired mic. Also the dynamic performance is almost the same.
