The Drawmer SL2120 is a hard limiter to ensure sound levels don’t exceed a specific volume. Designed for clubs where a noise restriction is in place. It can also protect you speakers from anyone trying to turn up the volume without your pemrission. Takes only minutes to install. Tamper-Proof bracket (available separately) to lock-in the XLRs and conform to Local Authority regulations. Dual 16 segment Left/Right bargraphs for ’at a glance’ level metering. ’Protection’ processing 16 segment bargraph display. No sound quality loss even during heavy protection processing. Once installed and calibrated completely eliminates the possibility of ’unauthorised’ volume levels. Eliminates sound system abuse and the resulting cost of chassis speaker re-cones, HF diaphragm replacements and amplifier repairs. Reduces ’call-out’ costs of sound system service/repair engineers. Reduces sound system ’down time’ and the consequential loss of venue income. Isolation transformer output option.
