Total is 4 amps. One Zapco 650.6(will upgrade soon), three Mosconi 2/10. How can I find out the limit on the DSP remote? Thank you,
Do I need a relay?
Hello,
We are using Helix .2 DSP and running a remote turn on out from DSP without any relay. We are about to add other 3 amps to my friend system. Do I need to add a relay to the remote turn on?
Thank you,

4 total.I interpreted 3 total but maybe I misinterpreted? 3 total will be fine.
Thank you. All Helix DSP have 500mA? My friend got the old Helix .2, where can I find those capacity?Depends on the DSP. Helix has like 500mA capacity which is a lot. Mosconi DSP on has 100mA. Amp draw is different for every Amp but is usually 50-75mA based on my research. Relay must have a diode to prevent voltage spike on power off.
Thank you, Sir. Just look at Max remote output on DSP .2 and it is 500mA.I was looking at the Helix Pro and Ultra, they both had 500mA from what I recall. This screenshot is for an Ultra. Look at Max Remot Output Current. View attachment 347352
Thank you, Sir. Will do that this weekend. Hope all not more than 500mA.this is a good point. You could measure your remote current draw of all your amps to see if you are below the threshold.
Thank you, Sir.
Thank you, Sir.With 500mA, I wouldn't worry about a relay. With a Mosconi and it's 100mA I would unless I was only running 1 amp. Just thought I would take a look at another popular DSP, the MiniDSP C-DSP 8 x 12 and its only 100mV also. View attachment 347353
I am about to build my own system now. Is idle current is an amp drawn from the amplifier? Please see attached below if the right one and it shown 3.5 A. This is Brax GX2400 amplifier.Depends on the DSP. Helix has like 500mA capacity which is a lot. Mosconi DSP on has 100mA. Amp draw is different for every Amp but is usually 50-75mA based on my research. Relay must have a diode to prevent voltage spike on power off.
I will be running One Brax GX2400, One GX2000, and two Mosconi 1/10. With Brax DSP with max. remote output current at 500 mA.
Thank you, sir. Drawing below is about right? Will be using 14 gauge for REM wire. please feel free to add any suggestions.That 3.5A is the current draw for the amplifier simply being turned on. That is not being pulled from the remote wire of the DSP. I don't see remote current draw in the specs you listed, but guestimating it's probably less than 100mA. The 500mA remote line of the DSP can probably handle the 4 amps, but if it were me, I personally would go ahead and do a relay. In addition, I would also stick a 500mA fuse on the remote out of the DSP. The fuse is cheap protection.
I was thinking about this busbar, anything better than this one?

Thank you. So will be something like picture below.Relay will go after the DSP. DSP REM Out 》Fuse》Relay 》 Amps
Thank you, sir.
Hi Bob,
Is this the right way how to wire DIODE Relay.
86 Ground
85 REM from DSP ( will be a 500 mA fuse in between REM and 85)
30 +12V constant (secondary battery) not sure if I need a fuse for this wire also
87 Amplifiers REM
This is the Diode relay https://www.amazon.com/gp/product/B07ZDJZCKW/ref=sw_img_1?smid=A5UR51Z4IJK5J&psc=1

Thank you, sir.That's a 5 pin, it may work but I don't know. Here is 4 pin and Mark @ CAF has a pretty good video on how to do it. He talks about relays around the 4 min mark.

Thank you, sir. Been searched on YouTube but don't see much on Diode relay but attached YouTube. Look at 4:45, he said that 86 is ground. I am confused. When he said 85 is positive, does he meant positive turn on from DSP in my case.Believe me you don't need relay...
Diode relay's terminal 86 should be positive...
Thank you, sir.2:19 is correct way. 5:50 is wrong, probably they missed it. Flyback diode cathode is always on positive...
By watched this YouTube again and again, still don't know how can I measure how much my REM amps drawn just like he did on this one?
I was thinking positive probe connect to REM from HU and negative probe connect to REM on the amp. Not sure if this the right way. Please advise.
