Omnitronic Spl-1 Spl Guard + Measure Mic

Guard system for limiting the sound pressure level

Features
Tamper-proof 2-channel sound level limiter with measurement microphone to meet legal noise regulations e.g. in discotheques
For insertion between the 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 to warn of impeding muting when the 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 the removable cover plate
All audio connectors and controls can be sealed
