SM58 to mobile phone

(At your risk).

Please reduce volume before playing.

Signal path:

Outdoors at SNFCC park -

Shure SM58 at 24in, 45o above head towards nose of singer - 

German Transformer 500 Ohm to 50 KOhm, primary inductance 230mH -

Pleiades K117 JFET microphone preamplifier (schematic on a previous post) -

Apple 3.5mm to USB C adaptor (with Philips in ear headphones connected to)

Xiaomi Redmi Note 13 Pro + 5G

Notes:

To my mind when I listen to it with the Sennheiser HD-580 headphones, it sounds bass or mid bass heavy. The Shure Unidyne B may do the trick as in my experience it can sound with flat frequency response from my mind as producer to my mind as listener without the need to add a frequency response EQ or filter after the microphone.

We need to use a much quieter outdoors place.
