Tech Specs (from the Drawmer website):
The Drawmer SP2120 Speaker Protector offers both strict level control and tremendous peace of mind to the contractor, installer and venue in the knowledge that, as its name suggests, the 1U, two channel processor eliminates the possibility of ’unauthorised’ excessive sound pressure levels on speaker systems (as caused by spikes and pops in the system, or by over-enthusiast DJs/engineers) which could result in damage to both chassis drivers and amplifier electronics.
In addition only the maintenance engineer and the venue manager hold a key. The unit also gives a wide variety of venues, such as clubs, theatres, pubs, schools, universities etc. the opportunity to comply with the local legislation regarding noise levels.
