Hello all! I purchased a Sonos Playbase and Connect. I have hooked my Linn Sondek Turntable into a Little Bear T8 preamp through the MC ports then into my Sonos Connect live in port. I am getting a VERY low sound and quality. Can anyone please help me?

So its a Linn Turntable with MC cartridge. RCA cable run from tuntable to the MC port on the pre-amp (switch on AMP is turned to MC). Then the OUT RCA jacks from pre-amp run to the Connect input.

Setup that way and audio is low. Have you looked at the level in the sonos app...settings...room...line in.

Does hooking the Turntable up direct to Sonos produce the exact same low sound or are you getting more sound going via the pre-amp.

Yes I checked all of that and the sounds is VERY low either way. I changed my room line in setting to 9. still VERY low sound....:(

IF the sound is the same plugged direct into connect or via the pre-amp. That tells me the pre-amp isn't doing anything. Is the light on beside the on/off switch beside where you plug in the pre-amp?

Check the cartridge.. wires, CW, pre amp settings (if any) etc. Have a Marantz tt-15s1 (with MC and Schiit Mani phono pre) plugged into the Line In of a pair of Play 5 in stereo and it sounds pretty damn good. (for the $)

But isn't this a MC to MM preamp? i.e. intended to take a MC input and boost it to MM levels, presumably also carrying out any necessary RIAA adjustments?

If so, then it's nowhere near the output necessary to drive a line level input, so I would expect it to sounds very soft indeed.

You could try changing the line in source level in the controller - AFAICS level 10 is the most sensitive, but I can't see what the settings actually equate to, so that may still be far too soft.

If it is like the usual MC+MM suitable preamps, it will take either the lower voltage MC signal or the higher voltage MM signal and boost both to line level suitable for the line in jack on the Connect. It does not seem to be doing this - was the preamp checked for defects? Does it work with other downstream kit, but not with Connect?

You'd have to ask the OP, but looking at the specs on a web site it implies that the output voltage is 3-8mV, which is far too low for a line input.
