Whether you need to protect your speakers, your hearing whilst listening to headphones or your premises license the
Drawmer SL22 Sound Level Limiter is the perfect tool for the job. By eliminating the possibility of 'unauthorised'
excessive sound pressure levels it offers strict level control and tremendous peace of mind to users in three distinct
areas:

SAFEGUARD YOUR HEARING
Conform to Noise at Work
Regulations by controlling user's
exposure to audio whilst at work
to help prevent hearing damage
Benefiting from Drawmer's 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 SL22 has
been designed to be more versatile and feature rich but at the same time just as easy to set up.
The key features are as follows:
•
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
•
Time delay relays on outputs for clean power up/down
•
Fast, simple installation.
•
Tamper-proof plate limits access to settings.
•
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 XLR's 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 statuses.
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
