Help with QSI install 2-6-6-2

[lqdsky]

The new updated board that is in the Mallet, is a little different
from the K27. This new board has a direct output for the speakers.

I went and replaced the dummy chip with the QSI Aristo chip. Plugged the speaker
into the QSI chip, not the bachmann board.

When I give it power, I get one short burst of sound, and that is it. I also tried using the speaker out on the board and a secondary QSI chip.

Ummm, is there something that I'm missing? With the K-27... I plugged in the speaker to the QSI chip and intalled on the board and everything was working.

I'm sure it's something easy that I'm overlooking. Any suggestions?

The QSI can make this burst of sound and then nothing in several situations.

One is miswiring...

Another is that the QSI is not set for DC/Analog mode (most likely)

Another is that the QSI has not had the sound file properly programmed.

Another is that the QSI was not plugged into the socket correctly (don't ask me how I know)... really a variant of the first cause.

Thanks for the reply.
I will check everything over. As far as the chip not set to dc mode.
I thought the chip automatically recognize the current and changes on it's own?
How do I go about manually changing the setting for DC?

I do have the engine up on rollers and using a DC transformer. I will hook up my DCC system.

I'm also getting playback error with the programmer. The programmer is sending the signal, as
the firebox is blinking. Has an error in the return signal. Something is not connected.

I will go over the connections again.

Thanks

The programmer will give you an error message...

1. read the loco info...
2. try reprogramming the loco, run confidence test first
3. if that works actually reprogram loco...

Not exact wording of error messages..

Make sure lights are off (switched off), too much load will interfere with the programming

Hi

I plugged in the Aristo Sound decoder , speaker to decoder and it worked just fine.

However I had the same programming problem with error messages and I discovered by accident that a Programming Tack Booster is recommended for use in programming the QSI.  I am waiting for mine to arrive

If you use the QSI programmer, it's no problem, and they give you 2 software packages, one does the sound downloads, the other sets's cv's.

If you are trying to program this unit on a DCC programming track, you might need a booster.

Try turning off the lights first, sometimes that helps.
