What would happen if I plug in a mono/TS phone jack into a balanced output socket that requires a TRS phone jack?

These sockets and plugs are designed to work in exactly this way. When you plug a 'TS' plug into a TRS balanced jack socket, the "ring and sleeve" are bridged. This is exactly the correct way to ...

What is the difference between headphone jack and line out on Zoom H5 Audio Recorder?

It's not a good idea, because the levels on both the line output and the headphone output are much too high for the camera mic input. If you were to turn the volume down on the headphone output, you'...

Why we require high voltage swing at the output of line drivers?

Headroom, mainly. Your peak voltage is 1.736 volt only when you have a sine wave signal of exactly +4 dBu (0VU on professional equipment). That never happens in the real world.. 0 on the meters is ...

Understanding various input lines types for mixing?

Here's a great summary of the different signal levels: Mic level is the lowest, or weakest, level signal of the four and requires a preamplifier to bring it up to Line level. Instrument level ...

Converting a 3.5in mic input to line level portably

Most microphones output about 0.0006 volts while line level is about 1 volt or 1.23 The device you want is a microphone preamp to bring the microphone signal up to Line level. If you get one with 1/4"...

Does a non-powered mixer have the same level of output regardless of number of inputs used?

There seems to be some essential misunderstanding of gain staging here. The output is the sum of the inputs, plus or minus the fader gains. 8 ins, 2 outs with all the faders pushed to the max will ...

In my experience this is a hardware issue. The sound is when the input hardware of the PC getting too hot signal and clipping. The first step to try then is to decrease the "gain" of the ...

Sending line-level signal to two devices

I suggest you put some resistors here just to be on the safe side, like this: L_IN1<------|2k|------+------<L_OUT L_IN2<------|2k|------+ R_IN1<------|2k|------+------<R_OUT R_IN2<--...

Mixer XLR out vs Line out

The biggest and most relevant difference is that one uses an XLR connector and the other uses a 1/4” TRS connector. This is helpful because you might want to plug the outputs into something that has ...

Guitar pedals + sound card: What's wrong with the combination?

It will not cause any damage to your pedals - as you can see from that video, you can pop effects in there quite happily as an FX loop. Having delay or reverb in their own effects loop isn't ...

Is my synthesizer too quiet?

Sounds like your signal is too low. This can come, e.g. from impedance mismatch (i.e. output and input aer a bad couple). Sometimes using the headphone output helps. A preamp inserted might help. ...

10-15 dB lower input audio level on audio interface than output level on source

One meter is displaying dBV and the other is showing dBFS. which is what was suspected by Hobbes. Typical line level for dBFS is going to be between -18 and -12. So no big deal like audionuma said. It ...

Do some dedicated sound cards have a "stronger" line-out signal than on-board chips?

There are sound cards with higher line out level, these are interfaces with a pro line out whose nominal level is + 4 dBu (compared to the -10 dBv of a consumer line out). That's around 1.2 V vs 0.3 V....
