tascam us428 signal problem.

[assassinofsilence]

Hello!
          I've recently fired up my us428 after a couple of years. I'm running os9 and cubase 5. Its all installed and configured correctly I think, Ive used it lots in the past. But now I can't get any signal to or from it. The midi controller is working fine but I can't even get a signal light when I plug a jack into it. Also when I play a click track there's no sound from the line output or the headphones. Anyone else had similar problems ? Any help is greatly appreciated!

did u install the asio driver file to the cubase asio folder?

which usb port do u have the us-428 plugged into?

Hi Chris, thanx for your reply,
All your questions check positively, my oms is 2.3.8 and I have tried both USB ports, currently using no1.
(I am using a g4 PowerBook btw, its dedicated to cubase and has little other software installed)

[supernova777]

have u used the usb ports with other devices + can confirm they function ?

have u tried a different usb cable?

[assassinofsilence]

I've tried a different cable and like I say the midi controlling is fine , does that tell us the port is working fully?

[assassinofsilence]

OK,I've got something here, a very faint signal from cubase to the line out, I can just about hear it with my amp turned to max? Still no instrument signal in thou :\

[supernova777]

u need to check the sync settings of the device in whatever utility is provided for the audio interface driver

it may be stuck in a specific mode which u have to disable/enable such as SPDIF digital sync etc
i dont have one of these interfaces so i cannot be absolutely sure

[assassinofsilence]

Thx for your help Chris, i guess I will have to get the tascam soundcard checked out

[supernova777]

personally if im having trouble with a device i always test it on another os + ensure that its exhibiting the same results..
ie: try setting it up on windows, try setting it up on mac os x..
to verify whether or not its a hardware defect or a software problem

Maybe i have an idea of  what is happening here.
Go to the controllpanel. There is an option to put the tascam as midi-controller-only , without audio functions.
Maybe you have to put it into audio-midi mode.
Hope it's only this.

[supernova777]

this is why i suggested u look at the control panel..

Assassin:
can u take a screen shot and post what it looks like here?
for everyones future reference?

Here guys, man I need this thing working, its Way too quiet around here!

OK ,so, the problem was the power supply adaptor.. The replacement matched the specs of the original but only acquiring a genuine model has worked and its firing on all pistons 😁😁

Can you post a picture of original specs vs "clone" ?

Only with Boss-guitar pedals I had the trouble of " not working good" with an similar PSU.

But PSU are PSU. A 5+ volts PSU with 1 A. is a 5+ volts PSU with 1 A. 

For PSU you always have to look Voltage, Amperage and Polarity. 

For example, most BOSS guitar pedals need +9 volts, 0.2 Amp. and the negative tip inside (positive outside). But the delay pedal need 0.5 or 1 amp to work right.

Most Yamaha-Sennheiser need +12 volts, 0.5 amp and the negative tip outside(positive inside).

Boss vs Yamaha have opposite polarity. I hope you get what I mean.

Other trouble can be the shape of the PSU jacks. That is the reason generic PSU for portables have more than 6 shapes

is that about right?
ive always wanted to get one just to use the control surface part

In that picture you can see the TASCAM uses AC instead of DC for the PSU...No polarity trouble.
 
In this forum http://homerecording.com/bbs/user-forums-by-brand/tascam-user-forum/us-428-power-supply-information-318292/ says AC Adaptor PS-P428 (7.5 VAC, 1000 mA)

Any AC/AC PSU from 220 or 110 to 7.5 with more than 1 A should work.
