## Questions & Answers

**Q: I had recently purchased this unit and jist waiting to arrive but how toconnect my active subwoofer to this amp. Hoping for your advise.. Thanks a lot**
A: Hope your active subwoofer has "speaker level inputs" as the only sub out on this amp is powered and not line level.

**Q: Can the sub out be bypassed for a 2.0 system?**
A: You dont have to use the sub channel, so yes.

**Q: how do i know which Hz my crossover knob is currently set to? I see no indication on the front. Just the knob.**
A: Crossover is 50-120hz. You have 70hz to play with, straight up on the adjustment should net you 85hz. Hope this helps.

**Q: What is the output of the amp on the stereo channel (not the sub) with an 8 ohm load?**
A: Probably 25 watts as it would be half of what the channel is capable with a 4 ohm load.
