FX Send and returns not 100% wet

Curious, I did a search but found nothing on the topic.

Question: On the MPC 1000, are the send FX and returns 100% wet?

Say I'm using a delay on FX2. When I turn up the send on FX2, my sound just doubles in volume. I also hear the delay.

If I turn the delay volume to zero on the return, all I get is a really loud sound (because it's doubled)

Is there a way to have the returns at 100% wet?

Thanks,
Adonis
