How to connect Stax adapter srd-7 to amplifier

Hello - I have just unearthed my Stax Lamda-Pro phones and the Stax adapter srd-7 - but I no longer have a clue which of the wires colored white, black,red, and green attaches to which amplifier output post. - can you shed any
light on this for me? Simple system - old NAD 7130 receiver, the usual turntable (AR), cd player(NAD) etc. Thanks. Robert Carr
Usually these are labelled on the back of the adapter. To the best of my recollection, green and white form one channel pair, and red and black the other pair. Red is probably hot (+).
Right you are. Thanks.
