Dear Sir,

I am very curious about this M1 "active impedance matching module".
Could you tell me anything about its schematic ?
Is it a buffer?
Maybe with a nice pot in front of it could be an even more basic line stage.

Thank you so much.
Kind regards,

beppe

Hello Beppe,

I'm afraid my knowledge of electronics is limited and the manuals for my Threshold equipment was lost in a flooded garage in 1997. What I can tell you is how the module works with the NS10. The M1 is for matching the impedance of various ( 900 to 1.5 ohms ) moving coil phono cartridges so, in my case, my Dynavector 23R plugs into the 1.5 -10 ohm input and out to the one of the NS10's magnetic cartridge inputs. It has one modification: I replaced the 6 47uF tantalum caps with Panasonic FCs. How does it sound? Real nice with quality vinyl, like say, "Art Pepper Meets the Rhythm Section,": solid, wide imaging through 15 ohm Rodgers Ls3/5a's and tight extended bass through custom Kef SP-200 EBS subs. So, yes, for impedance matching MC phono cartridges the M1 through the NS10 is great. I couldn't say for other applications.

Thank you Nelson Pass.

Check Nelson's list for Threshold SL10, you will find what your looking for on that schematic sheet.

Default NS10 specs

Hi!
Could somebody tell me the specs of the NS10?

How much gain has it? How many output voltage, impedance etc.?

Is it as strong as the BOZ?

Default Levinson JC-2

The picture on the post is of the SL 10 which has an outboard power supply. Of which most other high end manufacturers later on copied. I think the SL 10 was the first high end preamp to use an outboard power supply. Although I cannot be a 100 percent on that statement.
The Levinson JC-2 had a outboard powersupply in 1974 with the line cords vast attached to them. Later in 1975 I believe they used a PLS-150 Powersupply for it.

Can buy a NS10 pre for my second system to replace a Yamaha C2-a but I'm not sure because of the age of at least 30 years.

Greetings
