When the output voltage of Q2 is high enough (typically around 16..20V) the relay goes to on state and the relay witches connect the speakers to the amplifier output. It takes typically around 5 seconds after power up until the relay starts to conduct (at absolute time depends on the size of C2, relay voltage and circuit input voltage).

His contention was that the linear amplifier had an actual hundreds-of-µS propagation delay from input to output, and in a basic feedback circuit amp that would not be possible. You don't need DSP or anything like that. Even a 40 degree phase delay at 1 KHz is over 100us. The filtering built into the amp could conceivably add quite a lot of delay.

Design and copyright by Tomi Engdahl 1998. This is a simple circuit which I built to one of my audio amplifier projects to control the speaker output relay. The purpose of this circuit is to control the relay which turns on the speaker output relay in the audio amplifier. The idea of the circuit is wait around 5 seconds ofter the power up until the spakers are switched to the …

Double-click on your primary audio device to bring up the speaker/headphones properties dialog, and navigate to the “Advanced” tab: At the bottom of this dialog, locate the option labelled “Allow hardware acceleration of audio with this device” and uncheck this option. By default, this will be selected, causing the problems described above.

Adjust the delay setting on your AV receiver or outboard delay unit until the echo goes away. When the delay is set correctly it will sound like one audio source is playing. Keep in mind, the audio is before the video (your brain may have trouble processing that and may make it seem as if the video is before the audio).

Here is the step-by-step process. The voltage across it is low. No bias current to Base of Q1 through R2. So, Q1 and RY1 do not work. C1 slowly charge current until full. Then, Q1 gets bias current, it works. To drive a relay pull two contacts together. Connect the speaker to the power amplifier. The delay time—we can set by C2.

Nothing is changed except connecting the sound system instead of the headphone. The delay is therefore most definitely from the sound system. TEST 1: Measuring 0-1ms. PC -> USB SOUND OUTPUT -> HEADPHONE-> MIC -> USB SOUND INPUT -> PC. TEST 2: Measuring 20-30ms. PC -> USB SOUND OUTPUT -> HIFI STEREO -> SPEAKER-> MIC -> USB …

The delay in audio is often incurred by additional processing in the AV chain. This is why the audio then appears slightly out of sync with the video. Can your TV pass through LPCM? If so, you could disable passthrough but set number of channels to 5.1 or 7.1. The Vero 4K will then decode the audio and send it as LPCM.
