This Morph 4k really isn't bad. Here's a quick test of a Mortal Kombat arcade pcb. The sharpness of the colour is magnificent.

Genlock was just added. Really a nice improvement:)

Magiclock (AKA “Genlock”) added to Morph 4k
We've refined the Magiclock mode for better performance:

This mode lowers output latency and decreases/ removes dropouts between resolution or console switches.

Get the no signal drop experience like triple buffer, while having the lowest lag possible.

Evening all. Looking for some help on this.

I have the Morph and any console that is connected to it via RBG SCART will produce a crackle on the audio on certain games. I have the Morph connected to a 4K DELL OLED via HDMI and all the RGB cables are high quality from RGC store. Anyone else get this and know of a fix? Ended up getting HDMI in my N64 to escape it, but cannot do that for the SNES.

If you use discord I would recommend that you join the Pixel FX discord channel and ask there. There are a lot of people willing to help out with stuff like this

Thanks. I don't use Discord! From what I've been reading, seems the Nintendo consoles audio signals are a little 'hot' and can cause distortion in a way other systems may not. A workaround I saw was to split the audio out into a dedicated stereo speaker set, so I'm getting one of these to test that out.

Have you tried removing and re-instering the Analog Bridge and the AV port cart a few times? The connectors used sometimes has some white dust in them that might cause this.

Do you have your consoles connected through Hydra 2 RGB Scart switch? Morph 4K is known to clip analog audio with N64 consoles. When you add hydra 2 rev scart switch to the chain it clips audio with all consoles going by my testing:

An audio controller should fix the issue as long your scart switch or scart cable has RCA/3.5mm jack audio output.
For example:

Unfortunately it can't be fixed fia firmware update

I've heard reports of this and I have been trying to replicate this here so far no luck every system I've tried has worked without clipping. On the N64 does it have this issue if you use the composite out + RCA via SCART? I don't have a RGB modded N64 on hand so I can't try that.

As Wobbling says there's definitely a known design fault with some of the Hydra switches that cause it to boost audio too high.

It should be a relatively easy fix to change the SCART backplate to add e.g a resistor to prevent this if I could just find a system that actually exhibited the fault for me.

I have tested it with a N64 RGB modded and without any mods directly connected to the Morph 4k using S-Video or RGB scart cable. In both cases the Morph 4K clips audio. It's easy to recreate the issue by launching a race and hit acceleration in RR64 as shown in the video. Give it a try Other consoles like SNES, MD, PS1, Saturn I have no issues with when connected directly to the Morph 4k.

So to my understanding there are 3 cases where audio clipping occurs with the Morph 4k:

1. N64 - modded and unmodded consoles. Other reports in the retro community confirm the issue.
I would guess it's the same hardware design flaw as with Retrotink 2K first batch:

2. Modded consoles but not all. Confirmed by reports.
3. Hydra 2 boosts audo which results in worse audio clipping and affects other consoles. Even with the R4k you can hear audio clipping when connected through the Hydra 2.

RIght, guess I'm hunting for composite cables tomorrow then lol.

[woodenman]

Not using Hydra or anything else. Just direct SCART from console to Morph. Happens with composite using SCART adapter, but I can always remove those audio cables and feed them to a Hi-Fi. Don't want composite image tho!!

[BuckoA51]

That might be a faulty bridge then, the Morph is definitely more sensitive to over-boosted audio but most consoles output line level audio within spec anyway, except N64 it seems.

[BuckoA51]

Right, so, tried my N64, fired up Ridge Racer 64 and went into sound test, no clipping.. tested the specific sound effect WP mentioned, still nothing... so did as advised and started a race and... yep there it is.

Pretty specific circumstances but it's there. Now at least I can replicate it I can work on getting a fix.
