Thankyou

Hi,

Are you sure it's not your audio interface that's causing the problem? I had the same thing with my Apogee Ensemble years ago, it would lose its firewire connection to my Mac for a couple of seconds when any other electrical device (lights, water cooker) got turned on that was connected to the same voltage group.

Funnily enough it did a couple of days ago without the oil radiator plugged in! So you may be right. It only happens when I have connected the kemper via spidif . But not with kemper disconnected at the kemper or mac end.

When the heater turns on, the voltage is dropping by 2 volts.
The voltage at my place is 250v and its dropping to 248v. I wouldnt have thought that was significant enough, but I’m open to being corrected.

I have a feeling its the interference that is causing the problem.

I will try recording the through the balanced outputs this weekend.

Thanks again.

Thankyou both for you replies and help in finding the issue. I will get my fluke tester out and check the voltage.

I do use the external power supply on the 8i6 already.

I also bought genuine SPIDIF cables.

I will also look into using audio cables too.

Really appreciate your help and the time you have put into helping me.

Cheers

I tried a few things today.

First up I plugged all my equipment in a Monster HTS800 power conditioning extension lead.

Logic without Kemper attached and on internal clock. No problems

Logic with Kemper connected via SPDIF. The issue happens - mutes the sound only for about 2 seconds when the heater is turned on. ( turning the thermostat round until the heater comes on)

Kemper on its own with guitar through headphones (Logic and Mac not connected) No issue

Plugged the heater into another socket on a different circuit still has the problem

Brought in another oil heater (smaller one) and it did the same.

Took the heater into the house and plugged in, with the Kemper attached to Logic via SPIDIF in the outbuilding. No problem

I found someone online who had the same problem with SPDIF and another piece of sound equipment. But no resolution to the problem.

My SPIDIF cables are less than 2 metres long, so its not like they are huge. I wonder if they are picking up interference?

??

I will try that out!

Thankyou.

Thankyou for helping. I am using powered focal speakers to monitor.
I have the power rack Kemper.
All I have on that circuit is the mac/monitors/monitor speakers/focusrite. Kemper and the Oil radiator.

Regarding call an electrician I am one lol.

Its on a 32 amp ring that only powers that room and items.

So plenty of power.

These sort of issues arent what I usually deal with.

The kemper doesnt actually go off. Its just the audio sound. So wondered if it was some kind of interference.

Im considering splitting the ring into two separate radial circuits so that the heater can be on its own socket. But I wanted to check if anyone had this issue before I try it.

Thankyou again

This is a weird one. (And my first post!)

I have a oil heated radiator in my little home studio. (Garage conversion)

It is plugged into the same socket as the Kemper.

It has a built in thermostat that turns the heater on when it gets below a certain temperature.

When it comes on I lose my sound for a couple of seconds.

I have my kemper connected to my focusrite 8i6 via SPIDIF. And that to my Mac mini running logic X.

Any ideas??

cheers
