#277939 - 04/07/10 08:55 AM Line Out
Gilles C. Gilles C. Professional Forumite! Registered: 09/04/10 Posts: 409 Loc: Dunstable, UK	I was wondering about the Line Out socket on my combo Marshall amp. As a keyboard plaer, I know what a line level output is but on a guitar amp, is it intended as an output for recording or connection to a PA mixer channel - thus avoiding using a mic - or is it used to connect a speaker cabinet? Or both? _________________________ Fender Telecaster Standard (MIM) Vintage V100HB (Les Paul style) £48 Squier SA-105 acoustic Behringer X V-Amp Marshall Valvestate 80V

english_bob english_bob Unregistered	^ Sounds about right, but you would need to check if it's speaker simulated- guitar speakers aren't remotely "hi-fi" (as you'll discover if you ever try to play music through a guitar amp) and essentially act as a fairly harsh high- and low-pass filter in that they don't reproduce those frequencies well, if at all. A non-speaker-simulated output from a guitar amp will sound harsh and trebly and won't be suitable for much of anything, unless you're after that particular sound as a special effect. Some pro-level effects units only operate with a line-level signal, so if there's a corresponding "line in", then it's essentially an effects loop. Edited by english_bob (05/07/10 03:01 AM)

The amp in question has both a Line Out and an FX loop with send/return sockets. How can I tell whether the Line Out is speaker simulated? _________________________ Fender Telecaster Standard (MIM) Vintage V100HB (Les Paul style) £48 Squier SA-105 acoustic Behringer X V-Amp Marshall Valvestate 80V

If that doesn't work out, post the model number of your amp and I could have a search on tinterwebs try and find out for you if you like? If its a modern amp its almost definately 'speaker emulated'. You could also try listening and try and determine from that whether its simulated or not by whether it sounds really shrill and high ended or not. Then again, most line outs I've used dont sound great anyway so maybe thats not such a scientific way of finding out. In almost all situations I will mic a guitar cab rather than use the line out. I'm a great believer that the speaker is one of the most important parts of an guitars 'tone'.

Gilles C. Gilles C. Professional Forumite! Registered: 09/04/10 Posts: 409 Loc: Dunstable, UK	It's a Marshall Valvestate 80V Model 8080 which, despite its name, is a solidstate amp. The generic Valvestate manual says: Quote: "The low level signal from this socket is specially filtered to enable you to link directly into recording or PA mixing equipment and to still achieve the Valvestate!guitar sound." Does that mean it is speaker emulated? _________________________ Fender Telecaster Standard (MIM) Vintage V100HB (Les Paul style) £48 Squier SA-105 acoustic Behringer X V-Amp Marshall Valvestate 80V

Scrooge Scrooge Old Timer Registered: 30/11/02 Posts: 1259 Loc: Aberdeen	Yes, that should mean that the output has some sort of 'speaker emulation' circuit on it. How acceptable it sounds is another story $;\)$ Steve. _________________________ I've always prefered natural sounds to the synthetic...and valves grow on trees, dammit!

Gilles C. Gilles C. Professional Forumite! Registered: 09/04/10 Posts: 409 Loc: Dunstable, UK	Which leads me to another question: what is the 'best' way to mic a combo amp? Single mic? Two mics? Type? Distance? Angle? _________________________ Fender Telecaster Standard (MIM) Vintage V100HB (Les Paul style) £48 Squier SA-105 acoustic Behringer X V-Amp Marshall Valvestate 80V

I'm sure you'll get all kinds of different answers from different people. Assuming the combo has a single speaker, my own preference is to use a single mic aligned coaxially with the speaker, i.e. lined up directly with the centre of the cone and pointing at it, about a cone-radius away. So if it's a 12-inch speaker, about 6 inches away. The mic must be able to handle the high sound pressure level without distortion, as the amp will be turned up to a normal playing level. It may be necessary to put an attenuating pad in the mic cable to avoid overloading the mic input. When recording I prefer to capture as clean a sound as possible and make any changes afterwards, e.g. EQ and adding room ambience. Miking for live performance may be different; I don't know, I've never tried it. Dave

Scrooge Scrooge Old Timer Registered: 30/11/02 Posts: 1259 Loc: Aberdeen	When I mic a guitar live I like to position it roughly halfway between the cone centre and the edge of the speaker, close to but not touching the grille/cloth. I'm not a recording guy, but whenever I do mess around with it I like to emulate the old close-mic with a dynamic - distance-mic with a condensor idea as best as I can with whatever equipment I have available. The best way to get a good sound when recording by far though is to experiment with placement till you get the right sound you want. As always with all things when mixing, its worth keeping in mind that what sounds best acapella doesn't always sound best in the mix! Mics to look at for close-micing (and live) are the good ole SM57 (good all rounder), Sennheiser E906 or E609 (warmer, better for country/mellower styles of music) and the Audix i5 (good for metal).
