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
-Housing design: (19") 48,3 cm rack installation
-Height unit: 1 U
-Power connection: Mains Input Socket (M) IEC connector (M) mounting version Power supply cord with safety plug (M) (provided)
