About: Whirlwind IMCOML 2-to-1 Line Combiner

Use the line level combiner when you want to create a mono mix from a stereo source but need to keep the original stereo signals isolated. It's great for feeding a DAT player or CD into a mono system or single channel on a board.

This unit not only combines two line-level signals into one line level output, it also compensates for the 6dB of gain that occurs when two in-phase signals are combined. A handy ground-lift switch breaks the shield connection between the inputs.

  • Connections are female XLRs in, male XLR out. 
  • Frequency response:±0.3dB 20Hz-20kHz
  • Total harmonic distortion + noise: Less than 0.025% at 1kHz
  • Isolation between inputs: Greater Than 42dB
  • Insertion loss: -0.6dB, 50 Ohms source impedance -3.8dB, 200 Ohms source impedance
  • Output level: -3.8dB with both channels at 0dB sine wave input, in phase
  • Maximum input level: +28dBm
  • Input impedance: 600 Ohms
  • Output impedance: Less than 100 Ohms
