Allen & Heath ZED 24 Repair. Part 1 : First look

[@ColinJamesPoulter]

Thank you so much for the power Led's for my Allen & Heath ZED 24 they arrived all safe and well this morning

[@Spiderelectron]

Welcome!

[@rufusdelux3222]

Very interesting videos, my Allen & Heath ZEDi8 will not power up. I have checked the obvious, plug fuse, continuity of cables and power switch. Will I now be looking at the main power board? and where should I start first? thanks

[@Spiderelectron]

Yes - start with the main power board. Look for obvious signs of failure first. Be careful it's a switch mode supply, and can have very high voltages present even when unplugged. There is a fuse - check that. Then look at NTC1 or the bridge rectifier on the input side. If you can, test Q1. On the output side, look at D2, D3, D4 and D7.

Just got a 2nd hand zed24 and can only use post fader aux's, 1 & 2 pre fader don't send any audio, only if set to a stereo pair.

[@GiovanniMastellone]

it would be interesting to know what AD/DA chip was in this mixer.. I'm wandering to buy a ZED as my main audio card, and I'm curios to know if the AD/DA conversion is good

[@moeddl]

So could you hear the music while muted very quiet or normal? Also if you set the Main Fader to maximum can you hear noise on the Headphonejack? At my ZED 14 I can hear terrible noise

[@YOGESHPALA999]

My 2 of channels are giving lower output then other channels what should i do

[@StudioFides]

Hi! I have a A&H SQ6, and I want to know If is it the same process to open it..? I mean about pull out faders and Rotary knobs to set free the top painel

[@Spiderelectron]

HI! I've never opened an SQ6 - but I belive you can remove the top cover plate with all the faders in place - can't be 100% sure though.

G'day the brown wire from the P7 on the PSU has come loose. Cct diagram doesn't show where to reconnect. Where does that connect? Cheers

[@muneerlibya462]

please help me. When broadcasting live, I do not hear any delay in the sound, why?

[@ex1stenz]

My zed 16 have the same mute switch issue, the button doesnt switch always the led and sound cracks on and off while moving the pusbutton

[@Logan112]

Great video, does the board have a polarity button to reverse the phase on the channels?

[@benballard7521]

No it doesn't

[@brandoninhawaii]

Hello, what could the issue be if the left right meters are no longer lighting up to measure input?

[@ColinJamesPoulter]

Hi I own this mixer and my power LED has stopped working could you please tell me what the value and type of LED I need to replace it with please. Thanks so much Colin

[@Spiderelectron]

Hi Colin. Thanks for watching! My mixer is in use at the moment, but I'll try to get a moment to find the info for you. Not very often that an LED fails, so I'd check for mechanical issues such as bad solder joints too.

[@ColinJamesPoulter]

@@Spiderelectron Hi any joy on that LED I need for my mixer just need the specs so I can order a replacement cheers in advance. All the best Colin

[@Spiderelectron]

@@ColinJamesPoulter Aye - looks like a typical 3mm Blue LED at 20mA with FWD Voltage of about 3.5 V. I'd be happy to send you one FOC as I have a bunch here.

[@ColinJamesPoulter]

@@Spiderelectron Yes that be great thanks here is my email [e-mail] and I can give you my address details 😎

[@ColinJamesPoulter]

@@Spiderelectron Hi great thanks my address isThe Alcove Studio 46 Eastwood Close Hayling Islnd Hampshire PO11 9DY

[@Davidjzmusic]

Hi , I have an zed and My problem is that I have a signal in my audio editor in my pc without using any instrument.. any advice? Before was okay. Thanks

[@Spiderelectron]

Hi. It depends what the signal sounds like ;-) Is it a valid signal, leaking in from somewhere, or just noise?

[@Davidjzmusic]

@@Spiderelectron I can’t hear a noise, but I see in the screen it’s minimum but before was cero and I didn’t change anything. It’s like tic when you plug something

[@nerdhound5891]

Trying to convince my GF that I should get this. Sh'es from Kirkcaldy so this video should help :)

[@krishnamusic6897]

Hi how to connect boss digital pedal delay to Allen and heath 24 mixer (without FX)

[@bigxrecords7375]

Is this an audio interface like can I record into a daw ?

[@Spiderelectron]

It does have a USB in/out but it only supports two channels which you can select from the group buses, or main L+R. It is not like modern digital desks that can route all the channels individually into USB. It does not support digital interfaces such as Dante.

[@bigxrecords7375]

SpiderElectron oh okay then I’ll have to get an audio interface lol I was like I can’t record through it ha but yeah I have this board rn and it’s very clean I’m so In love with it

[@cartoon-galaxy8707]

Bro my allen heath Qu 32 digital mixer some times not working the touch screen and the faders and some times its all the switchs are not working and some faders are vibrate or not perfect working. How i can solve or solution pls give....

[@Spiderelectron]

It's not easy to diagnose from a distance, but it sounds like you have power supply issues. Chek all the power rails with a 'scope and look for under/over voltage and excessive ripple. Look for obvious problems like swollen capacitors and overheating.

[@yungman3033]

MY ALLEN AND HEATH ZED 32 CHANNELS 436 .ALL INDICATOR AND SIGNAL LIGHT ARE WHAT COULD BE THE FAULT..CAN YOU HELP ME ?

[@Spiderelectron]

Sounds like a power supply fault to me. I would start by checking the power supply unit. Good luck!

[@yungman3033]

@@Spiderelectron power supply is working alright 15 volts negative 15 and 48 volts for phantom is good but still i change all regulator except TL 783 i cant find it here to buy any equivalent ? still good power.

[@anil8044]

Aux1 low volume whats the problem
