Studer A1
Active Close Field Monitor
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.
