Single Head TK-790H - No sound coming from the head speaker

Any idea what I could be doing wrong?

Thumps when I power on, no beep from the radio or anything.

Got the little pin thing out that plugs in to the back of the radio but still doesn't do anything.

Help is appreciated.

you need to plug the short jumper into the molex connector in the back. i believe the pins are 2 and 6 if you need to make a jumper but im not 100% so if someone here *cough* code3cowboy could confirm.

If I remember correctly, it's pins 3 & 6. 2 & 6 are for a cab speaker. Looking at the plug with the two notches on top they are numbered 1,2,3 then 4,5,6.

Yes, jumper pins 3 & 6 on back of radio for a control head speaker.

Is this a basic head and you are trying to use the internal speaker, or are you using an external speaker to the head (basic or full function)?

What I don't like is "thumps when power on". This would indicate that the speaker is indeed connected to the audio PA (either the A side or the B side). Do you have a button for programmed for public address or speaker A/B. Either of these will switch to another speaker output. Speaker A/B will put a small "SP" on the display. Public address will say that instead of channel name (makes it obvious).

If that is not the case then there may be problems deeper in the radio.
