求助:请大家帮我解释下这段文字的含义…
在line6 pocket pod的说明书里,对于箱体的设置有下面一段说明:
A - feeding a power amp input closed back (ideal for 4x12 cab)
B - feeding a power amp input open back (ideal for 1x12)
C - (default) feeding an instrument input open back (ideal for 1x12 or 2x12)
D - feeding an instrument input closed back (ideal for 4x12)
Direct - feeding a recording device, mixer, live P.A., etc. not connected
因为我不太了解吉他音箱,对于这段说明有几个问题:
1.“feeding a power amp input”是不是说关闭外接音箱的箱头(preamp),用pocket pod作为箱头?
2.“close back”和"open back"是什么意思?
3.在"Direct"模式的含义是什么?不是说直通到P.A,而关闭了pocket pod自己的箱头箱体吧?
