Risk of damage to chassis drivers and amplifier electronics, whether by spikes and pops in the system, or by over-enthusiastic DJs and engineers, is here eliminated by the Drawmer SP2121 Speaker Protector. Its two-channel processor offers strict level control to prevent the possibility of "unauthorised" excessive sound pressure levels on speaker systems - and since only the maintenance engineer and venue manager hold a key, all parties concerned can have complete peace of mind.
The SP2120 front panel features an integral security lock to ensure that maximum volume levels are never adjusted by anyone except key holders. In 'unlocked' mode two front panel pre-sets are exposed and available for adjustment by the installer: the first calibrates the 16 segment Left/Right bargraphs to the incoming audio, dictating the point at which 'protection' processing commences; and the second sets the absolute volume level to which the sound system is allowed to perform. If the SP2120 receives increased signal levels, the transparent 'protection' circuitry is activated which maintains the specified system volume level without degradation in sound quality. An ingenious solution to an age-old problem, the SP2120 is one piece of gear no live venue should be without.
