You can set the SL130 so the RED LEDs flash when the sound level is below the"LO" set point where people in the audience may not be able to hear. When the sound level is above the "LO" set point, the GREEN LEDs indicate the sound level is acceptable. You can reverse the Red and Green LEDs activation per user color preference. Wall, desk or tripod mount with optional 15ft (5m) microphone extension cable for remote monitoring. User settable high or low limit (30 to 130dB) with output to drive external relay module.
