Yamaha v675 and Logitech z-2300


Novice Member
Hi All,

I have just recently started to upgrade my viewing/listening pleasure in the Lounge. So got me an LG 42 led, yamaha v675 and want to use my old pc speakers (logitech z-2300), until i can afford proper speakers. Problem is that the input to the pc speaker is in the form of a 3.5mm jack which is connected to a power on/volume hub.

My idea was to get a 3.5mm 'female' jack to RCA/phono and then connect it to AV receiver audio output (RCA/phono) but i've been stopped in my tracks by a word of concern from a friend about suitability and possible damage to the AV receiver itself (which got me disturbed hence need for experienced advise) because of using pc speakers on the yamaha v675. So please below are the respective specs to help your informed advice/suggestion.

The Logitec speakers have their own amplification built in (the are 'active'). As a result the least worst connection would be from the receivers headphone output (or the equivalent on the TV) to the line in on the speakers. You could connect to the tape output too. This would bypass the receivers volume control. Either way, you shouldn't use the speaker connections on the Yamaha until you have suitable speakers.
