请教各位大佬，下面步骤13是二类带的偏磁调整，那12这步骤是一类带的偏磁调整？LH 是一类带的意思？
小白刚入门，大家见笑了。

12.     LH Tape Bias Adjustment

·Input signal :  1kHz/10kHz (LINE IN)
·HX PRO SW :  ON
·LAdjustment location :  SFR563
Method:  Input a 1kHz signal and adjust REC LEVEL VR so that the output level of LINE OUT jack is 54mV.      Record, play back the 1kHz and 10kHz signals, and adjust SFR563 so that the output difference is 0dB + 0.5dB.
