I got a super prompt and helpful response from The Man Himself, Pat Quilter. Here's what I learned (paraphrasing Mr. Quilter) about using the SuperBlock as a preamp:
-- The Line Out roughly corresponds to the “-10dB” consumer level with about 2V peak on full Master, which should normally drive a power amp to full scale.
-- If the Mac has an XLR input it should work well.
-- If connecting to an unbalanced input, connect tip to XLR Pin 2.
-- I can also use a mono ¼-inch cable to pick up the headphone signal, as an alternative.
-- The FR/Cab Sim switch will affect this signal so you can select the position that gives the best results to your ear.
-- Once I have this going, I can also try using the 25W output of the Superblock for comparison.
-- The Mac will probably have a tighter tone since it is a hi-fi amp with a good damping factor, compared to the “warm loose” sound of the Superblock amplifier.
Now, this is from the Mc50 manual:
-- The input sensitivity of the Mc50 is 0.5 volt for 50 watts output.
--The input impedance is 200,000 ohms.
-- There is a gain control in the input circuit to permit the use of input voltages up to 30V.
-- The input jack marked 0.5 volt input is located below the gain control.
-- Plug the shielded lead from the input source in the input jack.
In my case, one wild card is that I had the input converted to a 1/4" mono jack and I know nothing further about how exactly it was done except that it worked perfectly with my FYD BF TR preamp.
I do have one of these already on hand: https://www.amazon.com/gp/product/B07S6 ... UTF8&psc=1
Can anyone help me make sense of this all? Thanks for any and all help!
