Hello all
Apologies if this is in the wrong section.
I have a Quad 99 pre amp and 99 CDP. I found it sounds best using RCA interconnects vs the Quadlink cable. Of course this disables the standby mode function, which is now missed.
Has anyone tried to alter a DB 15 cable so that only the necessary pin for bring in or out of standby is connected?
I've seen a few forum posts that state pin 7 is responsible for this function between the 99Pre and the 909 (but that would be the Ampbus connection), I need the pinout for the pre>CDP (Quadlink not Ampbus)
99 pre pinout
Does anyone know which pin i should be targeting?
Thanks in advance!

Try checking for continuity between pin 15 of IC 29 and a pin on the output? That seems to be the standby controller if I’m reading it correctly?
That Standby pin goes to the Ampbus connector, which goes to the 909 power amp.
Its the Quadlink pinout that I'm looking at, these are the connectors that go between the pre/CDP/tuner.
The Standby function doesnt seem to be listed on the Quadlink

Is it possible that it's a digital signal that triggers the standby? Is the signal from the CD Player to the Pre analogue or digital? Are the RCA outputs disabled when the connector is plugged in?
Otherwise, you could go the other way and lift the analogue pins on the connector so that the analogue signal goes over the RCA not the Quadlink connector?

"Otherwise, you could go the other way and lift the analogue pins on the connector so that the analogue signal goes over the RCA not the Quadlink connector?" - this is what I'm trying to do. Only have the required pin to bring in/out of stanby using the Quadlink and audio to go over RCA.
Not sure if its a digital or analogue signal. you have to select a different input when using audio from RCAs vs audio with the Quadlink
I've seen a few forum posts where people are doing this between the pre and 909 (Ampbus) but cant find anyone thats done this between the pre and CDP!
