Drawmer SL22 Sound Level Limiter
Drawmer SL22 Sound Level Limiter
Benefiting from Drawmer’s more than 30 years involvement in designing industry standard dynamic processing devices, and especially the experience gained from its sister product, the popular SP2120 Speaker Protector, the Drawmer SL22 has been designed to be more versatile and feature rich but at the same time just as easy to set up.
The SL22 front panel features an integral security plate to ensure that adjustments to maximum volume levels are implemented by authorised personnel only. Once removed two front panel pre-sets are exposed and available for adjustment by the installer. The first calibrates the protect indication to the incoming audio and dictates the point at which ’protection’ processing commences. The second sets the absolute volume level to which the sound system is allowed to perform. If the SL22 receives increased signal levels, the transparent ’protection’ circuitry is activated which maintains the specified system volume level without degradation in sound quality. With the security plate replaced a security label can be placed across (supplied) to provide further security and show evidence of tampering with the settings. In addition, on the right side of the panel three LED indicators complement the simple setup with simple and ‘at a glance’ monitoring.
Drawmer SL22 Features:
- Limited speaker and headphone outputs
- Once installed and calibrated completely eliminates the possibility of ’unauthorised’ volume levels.
- No sound quality loss even during protection processing.
- Large LED level indication for ’at a glance’ monitoring of signals and warnings.
- Fast, simple installation.
- Time delay relays on outputs for clean power up/down.
- A security label is supplied to further secure the calibration settings and show evidence of tampering.
- Tamper-Proof bracket (available separately) to lock-in the XLRs and conform to Local Authority regulations.
- Reduces ’call-out’ costs of sound system service/repair engineers, sound system ’down time’ and the consequential loss of venue income, as well as the reputation of the venue.
- External control of Dim and Mute for connection to Fire Alarms or remote operation.
- Trigger output when in PROTECT mode.
- Logging inputs for both ALERT and PROTECT status.
