SI 29-5
Sennheiser SI 29-5 is 5-Channel Modulator
This modulator's five audio channels can be easily programmed to any of the 32 narrow-band channels, and several units can be cascaded to make systems of up to 32 channels.
Monitoring is no problem due to integrated IR transmission diodes and clear LED displays for all modulator functions.
