Guard system for limiting the sound pressure level
- Tamper-proof 2-channel sound level limiter with measurement microphone to meet legal noise regulations e.g. in discotheques
- For insertion between mixer and PA amplifier(s)
- Guards the speaker level and gradually attenuates the output signal to the preset maximum SPL, muting can be switched on
- 3 operating modes can be selected: limiter with muting after 60 seconds, muting after 60 seconds, limiter
- Threshold control for setting the maximum admissible SPL
- 3-color LED indicators warn of impeding muting when level is exceeded
- Connection possibility for external warning indicators (optional)
- Inputs and outputs via balanced XLR connectors
- Trimmer and mode selector for on-site calibration behind removable cover plate
- All audio connectors and controls can be sealed
- Rack installation, 1 U
