My Laney Lv300 Tube Fusion Combo amp, doesn't have a Line-In, as such. It merely has one "Input" on the front, for the guitar and a pair of FX sockets, as an FX Loop (FX Send and FX Return). It also has one "Speaker Out" socket, for connection to an 8ohm-plus extension speaker.
What I need to know is this, is there any way for me to connect an MP3 player for example, to this amp?? I know that it is a Valve Driven Pre-amp Combo and that the two inbuilt 12" Celestions may not be the correct ones to give me an excellent audio out for general music, but my requirement is just to be able to generate an acceptable audio outside, for a forthcoming Open Day. I do also understand that the potential Stereo output from the MP3 player will have to be resolved to mono.
I do have a pair of 8ohm PA speakers that I can use as well. I plan to plug one extension speaker, into the single provided extension socket and I also plan to install a separate second output socket, into the rear of the amp cabinet, using a switched 1/4" Phone socket, that should then isolate the inbuilt speakers, when the extension is plugged into it. That will allow me to run at the minimum 4ohms that the amp requires.
Any thoughts, comments or suggestions on the best way to do all of this, would REALLY be appreciated. The speaker mod, I am sure that I can resolve, but the method of connecting an MP3 type player into the amp, to play music for the masses on that day, is something that I am desperate to sort out.
Thanking you in advance for ANY help with this....John.
I have managed to partially answer my own question. I dug out an old Vestax PCV-150 that I have and ran a 3.5 stereo jack from the player, which terminates in 2 phono jacks that I plugged into one of the Line input banks on the Vestax. The output from the Vestax, has been taken from one of the two "Sub-Master" 1/4" sockets, connected through a standard guitar lead, into the Laney amp Input. I plan to try using a "split lead "Y" connector", which will allow me to use both of the Sub-Master Outputs from the Vestax, as soon as I have one available, whilst still using the guitar lead into the amp.
Latest update.... I purchased a 1/4" "Y" split lead recently and connected the joined "Y" end, into both of the Sub-master output connectors on the Vestax. As previously, I then connected the remaining portion of the "Y" lead, into the Laney Input. This appears to now work exactly as I need it to. Thank you to everyone that has posted comments here, to help me with this. I hope that this post ends up being of help to others, in a similar predicament to myself.
