We investigate the interaction of an atom with a multichannel squeezed
vacuum. It turns out that the light coming out in a particular channe
l can have anomalous spectral properties, among them being an asymmetr
y of the spectrum. an absence of the central peak, as well as central
hole burning for particular parameters. As an example plane-wave squee
zing is considered. In this case the above phenomena can occur for the
light spectra in certain directions. In the total spectrum these phen
omena are washed out.
