I need the millivolt output recommendation

If you are experiencing low volume output from your Icon IC 41 Pro speaker/microphone, there could be a few possible causes. Here are a few things you can check:

1. Check the volume settings: Make sure that the volume on your speaker/microphone is set to the maximum level and that the volume on any connected devices (such as a phone or computer) is also set to the maximum level.
2. Check the audio source: Make sure that the audio source (such as a phone or computer) is not set to a low volume level.
3. Check the cables: Make sure that all cables are properly connected and that there are no loose or damaged connections.
4. Check the battery: Make sure that the battery of the speaker/microphone is charged or replace the batteries if necessary.
5. Check the speaker: Make sure that the speaker of the speaker/microphone is not damaged or blown. A damaged speaker can cause a low volume output.
6. Check the microphone: Make sure that the microphone is not covered or obstructed. A covered microphone can cause low volume output.

If none of these steps resolve the issue, I would recommend contacting the manufacturer's customer support for further assistance. They may be able to provide additional troubleshooting steps or may recommend a qualified technician to repair the speaker/microphone.
It's worth noting that if the speaker/microphone is under warranty, you should contact the manufacturer to have it repaired/replaced.

I can help you with some basics

If I were to guess from the information you submitted, your Thorens, which needs a specific phono input, is now plugged into a high level input, such as an AUX, DVD, CD etc. These inputs are for a 300 Millivolt input device. Your magnetic cartridge is no where near 300 Millivolts; never measured it, but would have to say a 1/10 of that. If your receiver doesn't not have a label that says "phono", you will need a phono preamp to amplify the output of your Thorens, with the very low input, to an output of 300 Millivolts. These preamps are sold just about everywhere, Best Buy, Radio Shack, etc.

Hi there,

From any port on a powered USB hub, you can draw up to 500 milliamps at 5 volts. This gives two and a half watts to play with; the peak draw of the SP-692p probably won't exceed two watts.

Hope this initial info/idea helps.

Let me know for any clarifications.

The click you hear is most likely the speaker protection circuit relay due to the protection circuits being triggered. In the event of a dc voltage appearing across the speakers the protection circuit isolates the the speaker terminals from the output stage.
Dry joints on the relay is not uncommon and causes false triggering. Check both pos' and neg' supplies are present at the output transistors / ic. Connect a dc volt meter across the speaker output terminals if a voltage of more than a few millivolts appears just before relay clicks then check the ouput stage for dry joints, leaky transistors and resistors having increased in value.

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

They run @ 12 volts 850mA. So an adapter with center pin positive at around 1A(1000mA) would give it enough "headroom". This means it would run cooler and last you longer. Amperage consumption is determined by the power it is producing, how loud you are playing the setup.

Model: PPI-0930-UL
INPUT: AC 120V 60Hz
OUTPUT: DC 9V 300mA
Polarity: Neg.outside, Pos.inside

Radio shack carries a universal kit with choices of many different voltage and milliamp combination. Bring your DVD player to them, and they can help find the one that best suits you.
