So, a couple of questions I've been asking myself these past few weeks from my last post here. Regarding the general noise floor of the console, I've decided I should recap my power supply to see what my baseline for other channel repairs might be. I've never recapped any old electronics, but...

I ended up taking the apogee out the rack and removed the odd numbered jumper pins (1-16) on the DAC output card for “pin 2 hot unbalanced operation” I also added an air gap between the console PSU and apogee. This seemed to fix my input and output issues.

Yup you’re correct. It’s interesting to me that an interface from 20ish years ago, I couldn’t get all the required information even from the company directly. If it weren’t for that forum I never would’ve figured out this problem. Thanks for the help on this guys. All the information I can get...

Small update because I’ve been so busy. I removed the apogee from the rack and took out the accessory DAC output card. I removed the odd numbered shorting pins for “pin 2 hot unbalanced output” and reinstalled the card. (this solution I found in a forum on gearslutz) also this information I...

So from top to bottom. M520 direct outs 1-16 normalled to Msr 16 inputs Msr 16 tape outs 1-16 normalled to M520 tape in 1-16 Non normalled 4 track output and input (red) (5-6 N/A) (7-8 Rca Stereo master A normalled to monitor amp inputs) (9-16 Rca 1-8 m520 program groups normalled to...

I’m just confused as to how the direct out is bleeding back a distorted harmonic into the fader when turned up yet no bus is assigned. But only when making a patch from the direct out

Thanks for taking the time to inform me about this stuff. Hm. So what do you suggest my options are, if you’re saying this extra cable is redundant?

I have my m520 direct outs on an unbalanced patch bay normalled to the line ins on my MSR 16. The input of my apogee AD8k is on a balanced patch bay with TRS (bay) to XLR. The output of the apogee is fully normalled to line inputs 12-20.

Interesting I have not tried this! But get this - my power supply has a 3 prong cable! So somebody must have modded it at some point? I have a morley hum eliminator that I use when recording stereo amps that I could use to try to incorporate your proposed solution but I know disconnecting the...

I will also say the apogee is sitting directly on top of the tascam psu in my rack. There is no grounding scheme or anything going on in my rack. I just have 4 patch bays (3 unbalanced tascams and one balanced nys) My furman conditioner, a midiverb, behringer 8 channel headphone amp, presonus...

Hey thanks for the response! I'm not sure how to go about bonding the chassis? What does this mean and how does it effect things? How would I bond them? I do have them plugged into the same furman power conditioner. I'm not sure if there's anything weird, all in all, I bought the console for...

Hey guys, a bit of a doozy here.... I have a tascam m520 and I'm trying to plug the direct out (out of a patchbay) to the input on an Apogee AD 8000 AD/DA convertor. Problem is that there is a slight distortion harmonic introduced to the signal in the background when making this patch happen, I...

So for instance, guitar on channel four, aux 1 gain turned all the way up, aux set to pre fader, aux 1 master fader turned all the way up, aux out 1 to the headphone amp input and again everything turned all the way up. Very very faint signal from the headphone amp output. I know the headphone...

Yes I have the manual and have read the aux section. That’s what I’m saying haha, I thought it worked just like that. Those faders were all the way up. Everything on 11 (lol)

there is only an aux out. The auxiliary bus is monitored via the main stereo master A or B. I’m taking that aux out and plugging it into the headphone source input and the signal is super quiet. The manual for the console says that these aux outs are -10db consumer line level outputs

I'm assuming the 520 has both input trim and aux master out controls. Initial individual input pre fader gain to the aux rail is dependent on where the input trim is set. Final output gain for everything sent to a given aux bus will depend on that aux master's out setting. So the only way to...

maybe a dumb question but right now I have a tascam M520 - > aux out 1 -> behringer ha 8000 direct in. The signal is very very quiet. When I go into the main in of the behringer, (or direct in) from the stereo master B, I get the proper volume. It was my understanding you can use the 4...

Hey awesome thread ! maybe a dumb question but right now I have a tascam M520 - > aux out 1 -> behringer ha 8000 direct in (8 channel headphone amp with a respective direct in for each headphone output.) The signal is very very quiet. However, when I go into the main in of the behringer...
