Copyright by STUDER Professional Audio AG The Studer A1 is a practical and compact active close field monitor. Easily carried around and installed the A1 will be most practical if you need precision monitoring in small spaces. The innovative design which involves Group delay compensation and Negative output impedance of the power amplifiers make this speaker an outstanding performer in its class. Particularly impressive is the ability to produce flat frequency response even at high SPL. The Studer A Series speakers are also ideal for surround applications. The Group Delay Compensation makes the Studer series of speakers ideal for Surround Sound. Mixing and matching of speakers is possible while correct phase response is maintained. For all applications the A1 will exceed your expectations with its size to performance ratio. Key Features: lMetal handle for stand mounting and easy handling. lVolume potentiometer on the frontpanel. lHigh Sound pressure Level over the whole frequency spectrum. lFlat frequency response. lHigh accuracy impulse behaviour due to Negative output impedance lHighly precise Stereo Image as a result of the Group delay compensation lDesigned for horizontal and vertical use. lPrepared for stand and ceiling mounting. lProtection circuit for each of the drivers. lSeparate amplifier stage for each driver (bi-amplified).
