请教小白版主关于Lavry DA10的跳线问题

以前问过一次，DA10的手册上有PIN2接地、PIN3接地的两种接法，接哪种最好。小白给了拍了张图：



这张图和我预想的一样，XLR/RCA的转换头PIN1和PIN3一般都是相连的，所以“PIN3接地”这种接法最合适。

但是，Lavry的技术支持是这么说的：

--------------
Just to clarify: for unbalance operation without changing the internal jumpers of the DA10 set for “Balanced Operation”YOU must wire the cable as follows Either:

A.) Front panel switch set to “Normal” for normal polarity.
Connect Pin 3 to the center pin of the RCA (or tip of a mono ¼” plug).
Connect Pin 2 to nothing.
Connect Pin 1 to the shield and the outer conductor or the RCA (or “sleeve” of a mono ¼” plug)

Or

B.) Front panel switch set to “Invert” for normal polarity.
Connect Pin 3 to nothing.
Connect Pin 2 to the center pin of the RCA (or tip of a mono ¼” plug).
Connect Pin 1 to the shield and the outer conductor or the RCA (or “sleeve” of a mono ¼” plug)

The DA10 XLR’s are wired for Pin 3 “+”

So Diagram (1) on the link is the closest to what you what to do, except that Pin 2 is the most desirable connection (instead of Pin 2).

Most adapters connect Pin 3 to Pin 1.

Dan lavry也提了一句：pin 2 and 3 are "interchangeable" when you set the invert switch to the proper position

也就是说，照图上跳线以后，polarity开关要放到“Invert”档位上？

具体跳哪一个还要看转接头的接脚怎么个连法.

有一个很简单的检验方法,
试试两个都跳一下,
有声的证明连对,无声证明连错了.

DA10很有意思的一点是,你不去改跳线,就用XLR转RCA听,照样会出声，但音场狭窄,打不开,其他方面没什么毛病. 而跳线后声场就一下子豁然开朗了.

leve:你摘引的,都是在"不动跳线"的情况下(without changing the internal jumpers ),应该对POLARITY做的设置. 我机器里都把跳线动了,就不用管POLARITY了.
