HTP-120 RadioFans.CN 收音机爱 好者资料库 SKW-120/HTP-120 PANEL VIEW (Front left/right, Surround left/right) The badge can be rotated depending on the angle you position the speaker. The badge can be rotated depending on the angle you position the speaker. The satellite speakers (D-120) and the center speaker (D-120C) have colored labels on the backs for easy identification. Match the color of the label with the corresponding speaker cable when connecting the speakers. The DR-S2.2 SPEAKER terminals are also colored to match the corresponding speaker cable. Connect the cable with a colored line to the negative (-) terminal. The label colors and the corresponding speakers are as follows: Front left speaker and speaker cable:White Front right speaker and speaker cable:Red Center speaker and speaker cable:Green Surround left speaker and speaker cable:Blue Surround right speaker and speaker cable: Grey A. LINE INPUT (input jack) Connect this jack to the SUBWOOFER PREOUT jack of the DR-S2.2. B. Indicator The indicator changes from red to green when the subwoofer receives a signal. C.
