Safeguard protection for your ears and your speakers.
The Drawmer SL22 is the line between your sound and safety. Protect your speakers and your hearing, or avoid nasty noise complaints and violations at your venue with the SL22 Sound Level Limiter. By eliminating the possibility of unauthorized 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 the level of the dedicated headphone output to prevent hearing damage to anyone wearing headphones on a regular basis - DJs, sound engineers in recording studios, students listening to audio via various media. Additional connectors on the rear can be used for remote data logging or to trigger external warning devices.
Conform to Regulations
The need to conform to Local Authority Regulations is absolutely imperative, none more so than in the area of noise control. Many products on the market claim to do the job but these often take the form of a crude switch, either turning off the power or disconnecting the speakers, both of which are very disruptive in any event.
The SL22 is different, it controls the volume, but in a transparent, unobtrusive way, that you will struggle to notice. Not only is it responsive and versatile but does so in a secure manner meaning that tampering is extremely difficult. Other features include remote dimming of the volume, as well as the connection to a fire alarm system, reducing the volume automatically during a fire and allowing the alarm to be heard more clearly.
Protect Your Speakers
Whether in a large arena with a PA system and multiple speakers, or a bar or theatre, there are few things more troublesome than blowing a speaker cone or amplifier electronics. The SL22 has been specifically designed to transparently catch those unwanted SPLs and protect your gear. Not only will it save money by reducing the cost of speaker repairs, but also reduce call-out costs of sound system service/repair engineers, lower sound system down time and the consequential loss of income, as well as the reputation of the venue.
