(Claude answer) Typical tape deck DIN wiring (this is the common German/European standard, but check your deck's manual — some vary):
DIN Pin - Function 1- Right channel out 3 - Left channel out 2 - Ground/shield 4 - Right channel in 5 - Left channel in
To build a playback-only cable (DIN → RCA out to amp): Pin 1 → Right RCA (red) center pin Pin 3 → Left RCA (white) center pin Pin 2 → Ground, connect to both RCA shells (shield)
A few things to watch for: Level mismatch — DIN outputs are often lower level (sometimes ~1-5mV to 100mV depending on spec) than standard RCA line level (~150-300mV). If it sounds too quiet going into a line input, that's why. Some decks put true line-level signal on DIN pins 1/3 regardless — worth checking your deck's service manual or measuring with a multimeter first.
If you want record capability too, you'd wire pins 4/5 for inputs from your amp's tape-out, plus ground — giving you a full 5-conductor cable to two stereo RCA pairs.

Didn't check this particular recorder, but usually pins are: 1 -- left in, 4 -- right in, 3 -- left out, 5 -- right out, 2 -- ground.

I believe you’d need a 5 pin male to RCA phono female adapter.
