Sennheiser SI1015/NT
2 Channel Transmitter Modulator, Half-Rack


The SI1015 modulator accepts line level input via an XLR connection and drives the SZI1015 (medium area) and SZI1029 (large area) emitter panels. By generating higher than usual sub-carrier frequencies, the SI1015 avoids the interference generated by electronically-ballasted fluorescent lights. A selector switch can be set for single or dual-channel operation, and the SI1015's external power supply provides DC power for two SZI1015 emitters or one SZI1029-24.


  • New, higher sub-carrier frequencies to avoid interference
  • Rack-mountable
