I need to record a choir in a hall to bring back to my semi pro studio to add to a track Im doing. Have tried a Zoom H4n but quality not good enough. Can anyone suggest something I could buy to get better quality? I dont want to use a laptop as my father needs to use it in his studio after iv'e finished (he's 83 years old) so he needs something simple to use!! Do you suggest adat/dat/minidisk?Also I would need some decent mikes that can be used for the choir and later in his studio.Any suggestions please?
