Switchcraft RMAS1
1x3 Mic Splitter


A passive 3-way transformer-isolated microphone splitter ideal for sending a single balanced audio input to 3 unique destinations. The RMAS1 features 100% isolation from noise and a truly uncolored audio output. It is ideal for connecting microphones, DI's, keyboards, etc. to multiple destinations such as monitor, FOH and recording consoles. In a broadcast situation it can be used to provide 3 isolated feeds from one source for ENG and news conferences.

  • Mu-metal shielded transformers eliminate ground loops, improve CMRR and block phantom power from interconnected equipment for ultra-clean audio paths free of hum and buzz
  • Direct output allows proper connection to pass phantom power for condenser microphones and active DIs
  • Ground lift switch on each isolated output for additional grounding flexibility
  • 40dB pad for use with line level equipment
  • Premium Switchcraft ferrite-shielded XLR connectors for extra EMI/RFI protection
