Description
Stellavox’s website suggests that the SP9 is the only professional portable tape recorder in the world in which format, functions and tape alignment can be changed instantly by simply exchanging plug-in head blocks and accessories.
The cost for transforming a mono machine into a stereo version with time code is only the expense of a new plug-in head block and modules.
