  We investigate the interplay of quark and meson degrees of freedom in a
physical state representing a near-threshold resonance for the case of multiple
continuum channels. The aim is to demonstrate the full complexity of
near-threshold phenomena. It turns out that those are especially rich, if both
quark and meson dynamics generate simultaneously weakly coupled near-threshold
poles in the S-matrix. We study the properties of this scenario in detail, such
as t-matrix and production amplitude zeros, as well as various effects of the
continuum channels interplay.
