It's the other way round: Inputs on 'pro audio cards' are primarily
designed for line levels, some even allow you to change the reference
level to interface with broadcast equipment worldwide. Connecting
instruments directly (or any other device with different impedance
and/or level) is the exception. That's what preamps are for.
