Las Vegas, NV (July 17, 2012)—TransAudio Group, a distributor of high-end pro audio products, has announced the release of the new Drawmer SP2120 Speaker Protector, a volume management unit designed to protect against loudspeaker and amplifier damage while providing compliance with any local noise level restrictions.
The Drawmer SP2120 aims to prevent sound system abuse and protects loudspeaker and amplifier damage due to excessive volume levels. Users can only adjust the controls on the two-channel unit by unlocking the front panel of the unit with a key.
Once unlocked, users can adjust the controls on the unit and calibrate the 16-segment left/right input bargraphs to a level at which protection processing is activated. A second preset on the unit allows the controller to set the maximum permitted SPL. Once the key is removed, the settings cannot be changed. The unit is inserted into the signal chain before the amplifier stage of a sound system to provide transparent maintenance of the pre-determined sound level through a combination of constant circuitry and automatic gain control (AGC).
A Tamper-Proof Security Panel is optionally available to prevent the removal of the rear panel XLR connectors. It can be retrofitted to any S2120 model with a serial number of 0845 or higher. Optional isolation output transformers are also available.
