This is an automatic mixer that automatically turns on only channels with input signals. It is ideal for adding microphones to video conferences (up to about 12 channels).

■ Type: Auto-matching mixer
■ Signals from multiple input microphones can be selectively output as needed.
■ By selecting manual mode, all automatic operation is stopped and the mixer can be used in the same mode as a regular mixer.
■ Up to 25 units (100 microphones) can be cascaded.
■ Input Impedance: MIC 8kΩ, LINE 50kΩ, AUX 50kΩ, LINK 20kΩ
■ Output Impedance: Balanced/LINE 200Ω, MIC 300Ω, Unbalanced 400Ω, LINK 100Ω, PREAMP OUT 750Ω
■ Maximum Input Level: MIC -24dBV, LINE +27dBV, AUX +17dBV
