Technics SL1500C Has 2 output choices:
1) Phono (and has an earth lead)
2) Line

I was advised to use the Line output of deck and phono of Amplifier (Arcam SA30).

I plug the line into the Arcam Phono (MM) sockets and I get background noise straight away. Then when I try to play a record its very loud and distorted.

I have not used the earth lead.

Is my amp faulty or should I be using phono??

I would be most grateful for advice.
 
You should not be using line out of the Technics into the phono input of the Arcam.

Technics phono out into Arcam phono in.
Or
Technics line out into Arcam line in.

You can then decide which of the two options sounds better to you.
@Gray is correct.
What you are currently doing is amplifying the cartridge signal twice.
No wonder it's noisy.
Whoever gave you the "advice" should be promptly ignored.... 🙂
Always an issue when someone buys a turntable with inbuilt phono preamp when they don't actually need it.....
On another matter the earth lead is there to be used.

If the op wishes to bypass the the 1500c phone stage they may have forgotten to the toggle switch on the back.
The advice is not bad per say but the OP or whoever has forgot a step.

though the id be include to use the one in the 1500c it designed from the ground up for the 1500c and optimised for it, its very fine sounding.
 
If we believe the advice the OP said he was given, then the advice is very bad because it's completely wrong 😉

Just as well he hasn't damaged his speakers.
(Best to read supplied instructions rather than rely on advice of course, but that's not the point).
Similar to the Cyrus post I suppose. Read the manual if you’re not sure.

Definitely phono out of the Technics to phono in of the amp and switch set to off (the switch furthest away from the plug - the closest one is for the auto-lift).

Also, if it is of any help, there is a little "hidden" auto-off setting in the Technics. If you toggle the tonearm auto lift switch to off, then toggle it to on again while pressing simultaneously the 33 and 45rpm buttons, it will enable not just the tonearm auto lift at the end of a record, but will also make the platter stop spinning (and, it seems, the whole TT to switch off - the latter function I am not to sure about but hey).

Many thanks to all who replied. I have now connected phono to phono + attached earth wire + switched the white switch at the back>>>>and the sound is good. Much appreciated - thanks.

Only played about 5 records so far but none of them lift off at the end. So need to investigate that.

(My old deck was a Technics SL1300 and was fully automatic - lifted off at the end no problem)

It does take a while. I had read 30 seconds - not measured it with just the auto-lift, but since doing the full auto off I have (in my head) and it is more like a minute...

So it rarely kicks in for me, but still good to know that if I ever forget (I can't "just" listen to music, I am always also doing something else, like right now) it's there as a safety net.

That seems to be a long time for an auto off facility, however if you find it useful all is good.

Yes I do.

Anyway, on another note, you don't get to agree with someone berating me and then continue "chatting" with me as if nothing happened.

I am funny like that, you see...

So what I said to Dave or whatever his name was applies also to people who liked his comment - which sole aim was to, as above, berate /make fun of me.

So long...

If you think that's berating you're on the wrong forum.
I was sincere in that some people require functions that others wouldn't, and I was stating the obvious, not chatting, simple as.
Please feel free to "ignore" me if you wish that way you cannot stop people posting comments but you don't have to read them.

Ridiculous. It's a forum, what do you expect? Please feel free to ignore me too. I've had plenty of spats with members in the past but I'd never hit the ignore button on any of them. I value everyone's experience and advice far more than my fragile feelings. If you are this way inclined then forum's are not for you.

My thanks for your comments.
I do try to assist rather than offend however some members are clearly a tad to tender to realise that, you, in your various guises, have been around long enough to hopefully appreciate that.

Ah OK.

I didn't understand that this being a forum, I should expect people to like comments which are exclusively and unprovoked patronising comments and personal attacks towards another forum user (as the comment in question, which made no other point but to pass me off as a simpleton or an "audiophool".)

Gotcha.

And actually not just I should expect it but also welcome it and dare not complain about it!!!

Yes yes yes of course. How silly of me to think that a forum is a place where you come to exchange ideas and opinions whilst respecting other users as you would in real life!

Maybe I am indeed a simpleton!

but old high output cartridges didn´t need pre-amplifier to sound loud and by the way neither all others sold ´till the year 2000, this is a new old thing as the new turntables ´till 5.000€ excluding the cartridge that costs to sound average the same amount, it´s sad but the truth
 
I forget to refer that gold note bellagio that as a gold note cartridge really sounds good but a pre-amplifier is needed and to keep the total quality of the output sound of the turntable it needs to be a expensive pre-amplifier or like some friends of mine that spend a lot of money in a turntable than buy a 30€ chinese tube pre-amplifier from Douk , the funny thing is that in the box comes with several actual chinese brands and a check in the litle square with douk brand at the side amongst others so what differs from the other brands it´s only the check on the brand selected, this bought from china and the sound is amazing bad, a tube pre-amplified device with a explanation that if you buy this or that tube it will sound better but is it better as in good or better as in garbage level of sound, a friend also bought a Arcam C49 and a amp. PA720 with some very good sounding Elac speakers and a gold note turntable too, the Pianosa with gold note cartridge it sounds real good with a pre-amp Rphono ,but he bought also a cd player from Arcam the CD27, what is that , it sounds really bad, but when he puts a SACD it sounds amazing ,well maybe to make people prefer sacd to the conventional cd, i refer to thi as i thought that arcam due to their bad quality amplifiers released in the 90´s had closed doors as today they look like garbage of so good materials they were built, i kept using a Pioneer and everyone that buy´s it today become amazed by it´s sound quality and released in 89 a good year for hi-fi at least is what it seems to me ,but about Arcam, it seems they are trying to improve themselves in this days, as regular materials with sober look have more apeal then the old 90´s very god amplifiers that today looks like garbage in a living room and i would never buy one or bought one , even sony had better amplifiers from esprit series

yes for the phono a phono input with earth conected, i found myself with a diferent problem, havng two excelent phono inputs i have to use a pre-amplifier connected to aux input so two inputs fior the phono are there for nothing , well i connected again my other 70´s turntablers and kept using the phono inputs it even a a litle knob to increase volume on the phono selector but not enough for a new good turntable with a expensive cartridge , also one could use the monitor on his recording device to increase the volume but not even with it you can year it sounding ok, well new equiopment was bought as i didn´t had bought nothing since 1996 , when i bought a thorens TD2001 that is stopped now because of some failure but not thinking in send it to repair as i have others that sound really good, again from the 70´s and a technics as i have several models from 72 to 79 only from technics, i bought three turntables in the 80´s none is working but while they worked they did sounded great , a technics, a pioneer and a mission cyrus, this last looked so minimalist that i was amazed by it´s sound this when cyrus was still called mission cyrus and all sounded good but the speakers for it are maybe the best 4 ohms speakers except the 89 AT-100 from cerwin-vega, any good amplifier not having usable tone contrls sound good with this mission s+peaketrs that recentelly sa a pair sold by 150€on Ebay and others that don´t have a 1/5 of the quality are sold for almost 2.000€ , the market was always very strange in what concerns to hi-fi
