Thank you for your contact. I am glad the set arrived and the face plate was undamaged. I think that you have the level set way too high on that circuit, and I would suggest lowering it all the way, engage the circuit and gently raise the level. The preamp, left here exactly as the ad described it. I also insured the shipment, which I did at no cost to you....so there is full insurance available from the postal service if it arrived in a damaged condition.
Let me know if the suggested operational change cures your complaint.
With my thanks,
上記の方法で問題が解決できたかどうかぜひお知らせください。
以上よろしくお願い致します。
