- Thank you, glad the video was helpful. When connecting one mixer to another it is treated like any other line level source, so you would plug the output of the submixer into the line level inputs of the main mixer, usually using two channels - one for left and one for right. Set the output level of the submixer to 0dB and set the gain on the main mixer appropriately.

Your video has been SO helpful! Thank you so much! We have been trying to get our tablet to work at church through the sound system from the front but have been running them through the wrong direct box.

@PassThisOn123 Thanks for the question. There are several things you could try: 1. Try using another cable - it's possible that the one you have is damaged. Make sure the plug is fully inserted into your laptop. 2. Use some electrical contact cleaner on your laptop headphone output - these connectors are notorious for getting dirty and then they won't pass a clean signal. 3. Try using another input on your PA system. How are you connecting to the PA system? Through the 'tape in' connectors?

- Thanks for the question! The HA60 is a mono system which means that there is only one amplifier feeding both speakers, so you're correct on that point. I would say the best way to connect in your case would be to use a minijack to 2 x 1/4" cable as described in my video, and use two channels on the amp - this would ensure that both left and right channels of the stereo signal are reproduced correctly.

@PassThisOn123 It's possible that the mixer's power supply is causing the buzz, so try and move the laptop around to see if the noise goes away. The buzz could also be caused by lighting ballast or a problem with your AC power. Try running the laptop on battery to see if that improves things. Have you tried using a different cable?

You're welcome. If you shop on Amazon consider using my buying links, they support the channel: glbproductions.com/index.php/amazon-links-direct-boxes/

- The main insert is for sending the signal to an external device such as an equaliser or effects unit and then returning it to the amplifier, using a single connector. If you watch my video 'how to connect the Presonus ACP88' insert points are explained in greater detail.

- If you use active speakers (ie with built in amplifiers) you may have noise issues as the unbalanced connection between the laptop and the speakers will be quite long. You could use a DI box like the one shown in the video to deal with this problem though.

- Mic inputs are generally designed to handle input levels of between 0.01 and 0.1 volts. Line levels are able to handle up to 10 times that level, ie around 1 volt. There are also impedance differences, with mic inputs being low impedance and line inputs generally being high impedance. However, some karaoke mics use a 1/4" connnector because it is cheaper to produce. Do you have any issues with low volume on the mic you are using?

- Yes, you can plug a laptop directly into your power amp using a minijack to 2 x 1/4" cable. The connection is unbalanced through, so keep the cable as short as possible and no more than 3 metres.

@PassThisOn123 It might be better, but first I would try another cable of the same type, if you have one, and also try cleaning the headphone output on your laptop as described above. A loud buzz suggests some sort of grounding issue, which could be caused by a bad connection. Also, how long is the cable that you are using to connect your laptop to the PA system? Does it run across any sort of power cable or power transformer on its way to the mixer? This can also cause buzzing.

Excellent! I could not have done any better if I tried. I will pass this on to a friend. Thank you.

- Yes you have it figured out! You would need a minijack to RCA cable to connect the laptop to the amplifier, and then you're all set. 5m would be fine.

- Glad the video was helpful! I'm not sure I understand your setup: are you saying that your laptop is connected to the input of your DVD player and you are trying to play sound from the laptop through the DVD player and thence to the speakers?

One note, I've worked on computers and audio equipment for years. Bruno says here to turn the volume on your PC to maximum. I am only slightly going to disagree with him. His reasoning is sound, however many laptops and audio devices will themselves distort if volume is ALL THE WAY up. I tend to set it to 95-98% of maximum to try to reduce this 'built in' distortion. If you have a fairly high end device 100% may be fine, but usually bumping it down 2-5% will get you a better result. If your device does present this mild distortion, you will then be amplifying the noise along with the signal. Always try to reduce noise as early in the audio chain as you can. Great job Bruno, love your work.

Thanks for the comment! In the years since this video was published I have discovered the above to be true in a number of situations - depending on the quality of the headphone amp in the device and the way it relates to the mixer's input section, sometimes you get distortion when the volume is set to 100%. In such cases, I will usually set the device output to 75 or even 50 percent and raise my channel gain accordingly. I've always found a happy medium somewhere 😄

- You're welcome, glad it was educational :) You generally will not connect the laptop directly to the speakers, you will connect to an amplifier first. This amplifier may be inside the speakers themselves (ie active speakers) or a separate unit, ie passive speakers with an external amplifier. Is this the setup you have?

Thanks so much for the Info. It is priceless and will solve many of the problems I've been having connecting to my PA System. {:-)

Hi Bruno, Much respect for you and appreciate the videos. I see you recommend against using stereo to mono adapters to sum the channels together. Well I agree these adapters are usually exceedingly poor quality and tend to create noise from poor connectivity. I have even had an RCA male connector pull the shield ring off these adapters which just goes to show that they are just press fitted separate bits of metal, not a continuous conductor. In my experience with single point audio, interconnect noise, buzz etc usually comes down to poor shield continuity, high resistance, even just inadequate shield gauge compared to signal gauge for the run length. I suspect that when these Y connectors are noisy, it's more likely due to the quality of manufacturing than anything else. However I am well aware that the usual recommendation is a resistive network and many people say there is a signal level issue if you tie L&R signals directly together. However I got to thinking about this in terms of it essentially being a parallel connection, where say you connect 2 DC cells in parallel, the voltage remains unchanged and that is the same as 2 channel peaks in phase. Now I understand the out of phase signals give destructive interference such as +1v -1v = 0v but all this is essentially what happens when we assign 2 channels to the same group or output channel of a mixer. So next, I decided to do a test and setup a stereo pink noise signal on 2 RCA outputs, measuring around 250-260 mV RMS. Then I bridged the 2 RCAs in parallel, just the same as one of those cheap converters and measured exactly the same signal levels, 250-260 mV RMS. So what's the problem not using a resistive network? There doesn't appear to be one at all. I have made up and used Y connections many times before with no issues at all. I get exactly the same phase issues and exactly the same audio quality summing to mono with a desk as I do with a DIY Y connection into 1 channel, no distortion at all and no gain issues. I had assumed that was due to the lower domestic signal standard and the pro desk headroom but no, my multi-meter says the channel signal level is unchanged by this. So, am I to assume all this talk about having to do resistive networks to sum stereo to mono is an industry myth to sell product? Have you tested this yourself, if so what is your opinion? Hmm, using resistive networks to sum to mono is just so ingrained but I see little evidence of a real need, no damaged equipment, no measurable difference in sum signal voltage and no obvious difference in sound at equalised output level unless the connections are faulty. Maybe I'll do a null test just to satisfy my own curiosity.

Thanks for the comment Ken. I'm going to direct you to the seminal article on this topic on the Rane website: www.rane.com/pdf/ranenotes/Why_Not_Wye.pdf The other issue which is not directly addressed in the article is summing two unbalanced outputs together into a single balanced input using a minijack to XLR or minijack to TRS adapter wired incorrectly - this typically results in the loss of whatever information is panned to the center in a stereo mix, often the lead vocal! I have seen this problem time and again in live sound, which is another reason why I give this warning. You seem to know what you are doing and have tested setups for your particular application, so if all is well do carry on.

Thanks! I was able to cancel my order for the minijack to XLR and ordered the cable you talk about in your video. Do you know what the "Link" connector is on the back of my passive speakers that came with my PA kit? I would guess it's to daisy chain speakers off one another. But is that connection in series or parallel? If it's parallel it will drop the load on my amp down.

Thank you! Very useful!

No that sounds perfectly normal. There is no 'correct' setting for the gain/trim knob, it depends on the level of the input signal.

Thanks for all your videos. Very informative. You mentioned that the laptop computer volume should be set to maximum. Would this also be the case for phones, mp3 players, etc (assuming their output is not too 'hot' for the mixer input). I wondered if setting at maximum would risk distorted output from the phone, etc, if the little internal amp went into clipping, or does that not happen with these little devices?

Hi Bruno, wonderful videos. We use them to train our novice sound volunteers in our church. I have a question: We hook a laptop to the PA and are currently using 1/8" stereo out of the laptop (headphone jack) which splits to two mono XLR cables which we plug straight in to a 2 channel DI box. The problem I've noticed is quite a bit of hiss coming from the laptop channels. Any ideas?

+Zstanman Glad to hear the videos have been useful! If you or your church would like to support the channel please consider signing up to become a patron at www.patreon.com/glbproductions?ty=h Every little bit helps! In answer to your question, there are several things you can try: 1. Make sure that the volume on the laptop is set at maximum, this generally gives the best signal to noise ratio. 2. Try a different, passive DI box - if the DI is active it may be the one that is causing the noise. 3. Try a different laptop - laptop audio outputs are not designed for hi quality sound and some are very noisy indeed. 4. Plug the laptop directly into the mixer's line inputs using a minijack to 2 x 1/4" jack cable and see what the results are. This will bypass the mixer's mic preamps which are another possible source of noise.

- You're welcome, glad you could order the right cable. Minijack to XLR cables often cause more problems than they solve, and it's best to run the output from a device like an iPod into a line input rather than risk overloading the more sensitive mic input. The 'link' connector is for daisy-chaining as you said, and it will be wired in parallel. However in this case, since the system is mono, daisy-chaining the speakers results in the exact same load as connecting them directly to the amp :)

Hello!! First thing I want to do is Thank You.. for taking time out of your day to make these videos. They are extremely helpful. I just have a question. I have all of our media players ( laptops, iPads and iPhones ) set to mono output. I use the 3.5mm TRS to 2 6.5mm TR R&W cable. I normally connect that to the stereo/mono unbalanced inputs like line 5/6. I have the pan set at center. Is this the correct way? Should I be forcing our media players to output a mono signal? We mostly do mobile DJ with just media playback.

@GLBProductions

Great to hear from you! Yes your method of connection is correct - if your PA system is stereo, there is no need to force the media players to mono output, unless your left and right speakers are so far apart that most of the audience is effectively only hearing one of the speakers.

You mentioned "sensitive" mic input? Is there a difference between the "line" vs. "mic"? We have a microphone we will be using from our Vocopro Karaoke system off our Home Theater but it has the standard 1/4 connection. Should be get a XLR to XLR cable for the mic to use the "Mic" connection for that channel?

It depends on your source material and the type of DI you connect to but in some cases you will lose whatever is panned centre in the mix such as the lead vocal. This type of adapter also shorts the outputs of the two channels together, which can damage the output of the laptop or CD/DVD player.
