Question about Fender Passport P-51 Consumer Microphone

Fender Passport P-250

I have the Fender Passport P-250, I loaned it out and they told me they tried to run it with weak power (Approx. 30v A/C) without success. Now all I get is the red L.E.D. marked PROTECT on the front panel above the Power switch and nothing more. I checked the fuse It is ok. Is there anything else I can do to reset this unit?

    Same problem, protect light is on. I checked the power output transistors and they appear okay (none shorted). That was my first guess, as the Protect light usually means a DC voltage on the output. Any schematics out there? I'm thinking possibly an incorrect voltage on a preamp output or a stuck op-amp in the Protect circuit.

Sorry about the delayed response, I just noticed this posting.

The protect indicates a problem with the output section of the amplifier. Effectively the amp has been shutdown to prevent further damage. Although the unit should not have been working (at least not well) at 30V, unless they htried to run it at full volume, there should not have been damage. The outputs are blown and this unit requires repair. If I remember these units correctly, there are 8 output transistors, most of which may require changing. WIthout seeing the unit and taking some measurements, I can not say for sure, but expect $40-$70 in parts.

Can I place my Fender Passport P-150 SPEAKERS ONLY on another system as ''extra speakers'' to a larger system. The larger system is a Samson XM910 900 Watt.


The speakers are 8 ohm (three 2 ohm in series in each cabinet).

You can connect them in parallel with others HOWEVER you cannot go below 4 ohms a side with your amp. This means you could use ONE other 8 ohm speaker in parallel with one of the passport speakers PER side.

Since the amp can vastly exceed the passport speaker rating you need to be careful to not overpower the passport speakers. One way to HELP regulate the level to the passport speakers is to use a LONG small gauge speaker cable on the passport speakers. Use a 50 foot 16 gauge speaker cable while using heavier, shorter cables on your mains.

With your Samson I would use mains rated at 300 Watts CONTINUOUS power, or at least maintain discipline in volume level to [revent speaker damage.

ALWAYS loop your speaker cables through handles of the enclosure to prevent them being pulled out during use which will destroy your amp... VERIFY the plugs are seated before pwering the system.

When the the Fender Passport 250 is plugged into the computer through the stereo out, there is feedback/buzz in addition to the sounds the microphones pick up, even when the mikes are off.


If there is a 120hz buzz then there is a ground loop between the computer and the passport. You need to get a ground isolator to go between the two. If the buzz is deeper the may be a audio ground off or the hum is comming from the power supply

Pluged into the wrong voltage


Hi,


You have to replace the power supply with exact voltage and amperage.
Be careful next time.

How do I open a fender passport 150 speaker cabinet?


There are screws running down the sides of the front panel which you will have to remove. The circuit board is secured to the front panel by the nuts, washers etc. that the controls and jacks are fastened with. Once you get the panel; loose gently move it forward so you can see any connections to the circuit board. Make careful note of all of these and draw diagrams. You will have to completely remove the panel from the enclosure and then the circuit board from the panel. The jack in question will be mounted on the circuit board and soldered to it on the reverse side. You will need to unsolder it, obtain an exact replacement, solder in the replacement and replace the board on the panel and the panel back in the enclosure. Make sure everything is connected exactly the way it was originally. Hope this helps.

Fender Passport makes loud chirpping knocking sound after on for only 5 10 minutes


I have one that is doing the exact same thing. It's at a Fender
Authorized Service Center now. Hopefully dude can find the
problem. Fender says there is a 5 year warranty on it, so I
expect them to make good on their promise. Did you get
yours fixed?
