I don't think I've ever seen a demodulator with a volume control.

Why not! Looks very cool! I wonder what the unlock button is for?I don't think I've ever seen a demodulator with a volume control.

I don't think I've ever seen a demodulator with a volume control.
I would assume that the 4-channel mode is auto. The carrier level might be automatic like the Marantz CD-400B (a good feature IMHO).The volume control is a very good feature. In my system, CD-4 volume is controlled by the amplifier volume controls and matrix volume can be controlled by the volume control on the decoder. Just one control for all channels. CD-4 requires changing four controls on the amps- decidedly unhandy. My amps have meters to match the channels but it's still a pain.
I see that demodulator doesn't have "4 channel auto".

Yeah, the separation pots look like even smaller screw-head types than on the back of the JVC 4DD-5. Maybe the ceramic was only meant for stereo, as this unit can have three turntables connected, and do both stereo and CD-4? Think of it as THE all-in-one phono amp (except for moving coil) that Technics may have made for the Japanese market?ceramic for CD-4..!?
"low" and "high" magnetic means it can handle MC as well as MM?
the separation adjustment pots look to be a fiddly recessed screw-head type?
Did you find the user's manual for either the SH-3480 or 3580? I'd be interested to see it if so.What does the "cartridge bias" switch actually do?
Found it:
"It is designed to supply a bias current to the semiconductor cartridge connected to Phono1 when the bias selector switch on the back panel is turned on.
If a MAG type cartridge is accidentally connected to Phono1, this bias current will flow, which is not desirable. To prevent such mistakes, when setting Phono1, a mechanism is adopted in which the selector does not turn unless the Lock button is pressed. I will.
The COM terminal which can share Phono1 and 2 is carried.
When a player is connected to this terminal, both semiconductor MAG type cartridges can be used properly simply by exchanging the shell and switching the selector."
So I guess it allows to have two sc carts or two mag carts connected.
No, just used translate on the audio-heritage webpage, here is the page for the 3580:Did you find the user's manual for either the SH-3480 or 3580? I'd be interested to see it if so.
Why is the PCB on the LHS positioned at a jaunty angle?

Could there be something on that board that runs hot, and they just wanted some air space (you know more discrete ?)Why is the PCB on the LHS positioned at a jaunty angle?

That little green board, near the middle looks bent over also.
Maybe they redesigned this board and it ended up being larger than the provided hole and fixation points. Tilting it allows a larger board to be fitted.Why is the PCB on the LHS positioned at a jaunty angle?
