Studer A-3 Brochure
Studer A3
Active Near Field Monitor
The Studer A3 is a high precision active near field monitor. Applying “Group delay com-
pensation“ and “Negative output impedance“ to a near field speaker represents a true innovation
in design philosophy, which makes the A3 speaker an impressive performer in its class.
The high SPL that can be produced over the whole frequency spectrum alongside the impressive
frequency response is quite unique for a speaker of that size.
The Studer A Series speakers are also ideal for surround applications. “The Group Delay Compen-
sation“ 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 A3 introduces a new standard of precision and will certainly change
your perception of near field speaker performance.
Key Features:
l
High Sound pressure Level over the whole
frequency spectrum.
l
Flat frequency response.
l
High accuracy impulse behaviour due to
“Negative output impedance“
l
Highly precise Stereo Image as a result of
the “Group delay compensation“
l
Designed for horizontal and vertical use.
l
Prepared for stand and ceiling mounting.
l
Protection circuit for each of the drivers.
l
Separate amplifier stage for each driver
(bi-amplified).
l
Rubber mounted non resonant power am-
plifier.
