I am confused, i just read the manual for this unit and it is the same as the studio preamp....meaning stereo out operation....how is it you had to mod it to do something it already does? (yes the individual channels come out mono, but they sum to a stereo output after the effects loop...meaning all effects and signals already come out stereo(frankly any division of the signal before the effects loop is pointless, because the signal is fed mono into any effect and then the effect adds its stereo mojo.....unless what you did was to make a stereo effect unnecessary and make the unit feed into the stereo outs without an effect to split the signal.....which to my way of thinking is also unnecessary......or did you go with both units feeding out at the same time so you get a different signal from each side....ie, mark ii right and mark iii left).....please clarify)JD said:I have loved the sound of my quad pre but the mono output of Ch1 & 2 has bugged me so I decided to seperate the preamps so I could run them in stereo.
I installed another input for ch2, removed the reverb and eq/reverb mixer circuit, used the recording outs for new outputs after the eq circuit of each channel.
I used 2 short cables from the new outlets to the effects returns which makes them separate channels bypassing the mixer circuit
I removed LDRs 2, 3, 4, 5, 6, 7,14 and 15, as these were used to allow switching between Ch1 and 2.
I always had a problem with volume and high end loss when using Ch1 and 2 together before now they sound great together.
I installed pull switches for lead mode, with LDRs bypassed the clean channel is always engaged so it works the same as the preamps in the Mark amps, I run the TC Electronic mimiq pedal in front of the quad into 2 x cabs sounds great its a keeper for sure.
