Question about Fender Passport P-51 Consumer Microphone

1 Answer

Passport 250 PD dropped face first and it loosened the inside speaker connection

Thank you for your wisdom.  I found a plastic plug in the back of the cabinet but when I remove it no srcew head, just a casing mark.  There are two screws in the front nothing more.  I thought if I removed the rubber trim around the front of the cabinet the speaker grill might pop out, but that did not work.  Thanks again, Tom B.

I have experience with the original Passport 250 as leader of the design team. To get inside of the speaker cabinet, you will need to remove a couple of small screws that hold in the grille at the top and bottom of the cabinet face. Once these screws are removed, you will need to carefully pry out the grille from its pressure fit in the plastic noting how it is placed so you can reassemble the grill later. Once the grille is removed you will notice several holes located around the outer perimeter of the speaker panel. Inside these holes, you will find the screws that secure the front of the cabinet (part with speaker attached) with the back of the cabinet housing. Once you have all of the screws removed, you can separate the front panel from the housing and fix the wires or dislocated parts such as crossovers, etc.

Once repaired, use the reverse method to reassemble the cabinet. Don't tighten the cabinet screws excessively as they can strip the plastic.

I hope this repair works for you.

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.

Could a bad cable connection make a fuse blow in my fender passport 250, or cuase any problemmwith ouput from my speakers...?


A shorted speaker cable could cause this... however, what you do is to replace the fuse BUT wire a 150 Watt lamp in series with the power input... This acts as a resetable fuse for testing. If the lamp stays lit, you still have a failure.

I have fender passport pd-250 the protect light on and the power light geos off


One or more of the power transistors are shorted. There are eight transistors in the amplifier section - 2 high & 2 low for each channel. This unit is difficult to open up to work on.

Unplug unit and check speakers with a multimeter to make sure they are not shorted.
Take off front panel (8 screws).
Remove power supply shield with yellow tape (2 screws).
Remove 2 screws holding top of power supply, loosen bottom screws.
Replace front and hold in place with a couple screws.
Turn unit around.
Remove screws holding heatsink (6 screws)
Open rear storage door.
Carefully pull amp section out, being careful of tightly routed wires. Note any connectors you disconnect.
The amplifier is the board on the top, the power supply is in the silver box.
Push the power supply forward and loose the black screws holding the amplifier board bracket closest to the heatsink.
Loosen the top brass screws holding bracket to heatsink and remove the bottom screws.
Remove all eight of the screws holding the transistor brackets & transistors to the heatsink. Look and take careful note of how the plastic insulators weave through the transistors. If you get this wrong, you can short out the whole amplifier when you turn it on.
Slide the amplifier board down and out where you can get to the bottom. Note the wires and connectors going to the small protect board over the amplifier.
Check the transistors with a multimeter to find the shorted ones. Remove and replace bad transistors. These are connected in pairs.
Reassemble in reverse. Be careful of reconnecting wires and insulators. Don't test until the amplifier PCB is back in place and you're sure of all wires. If the PCB is touching the power supply, you'll short it out.

Good luck, I told you this wouldn't be easy!

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.

Hello...I am an owner of the Fender Passport PD-500 Sound System


Replace the fuse only once. If it blows right away, then servicing is required as continued replacement will likely damage more inside.

Most of thes have a fuse holder that is a part of the input power socket. There is a little rectangular panel adjacent where the cord connects with a tab that you gently pry out and carries a small fuse. Replace the fuse and re-install the carrier.

These units are very hard to work on due to packaging.

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

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.
