ALS 120 recording poor

I am trying to get the microphone on a ISA card from 3D Melody with the Avance Logic ALS 120 to work. This is for an elementary school and they have bought 20 of these cards for some (old) Vectra HP VE 5/75.
The microphone recording level is normal, but is very low. When it is increased the static becomes unbearable and also affects all audio.
Any help would be greatly appreciated. The drivers are current.
