Does samson db1800 have a fuse for speaker

Do you have the manual ? If not here is link to the Free pdf file....

they have a service # also

These are passive speakers, so if there is a fuse at all it will be as a high frequency protection circuit on the crossover.

Have you checked the power supply section? Also look out for any IC's in the amp stages. They can go causing that kind of fault.

push on the speaker lightly to see if it moves in and out easly if not the speaker could be blown if thats ok pull the speaker out of the box and check out the terminal see if they are worn

Usually that lamp part ONLY protects the tweeter. If the woofer doesn't generate sound, then you probably blew the speaker as well. This speaker is rated at 250 Watts PROGRAM... that means your amp you drive this with should be no bigger than about 150 Watts RMS or you can blow the speaker. You should be able to get reasonable sound for a 20 foot square room with this unit.

Heat.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Turn the volume down? Feed it cleaner source material?

You don't say under what conditions you're blowing them or if any of the informative indicators are warning you of impending doom. The Samson is capable of cooking just about any home speaker.

The following conditions will cause the Protection LED to go on:

• Initial power-up: For approximately five seconds after initial power-up, the

protection circuitry is activated and the speaker output is muted. If everything is

operating normally, you will hear an audible click at the conclusion of this brief

period, as the protection circuitry is deactivated and the S1500 / S2000 begins

delivering signal to connected speakers (at which point you'll hear a click). It is

normal for the Protection LED to fade gradually after the amplifier is powered off.

• Overheating: A temperature sensing device in the S1500 / S2000 will cause

the protection circuitry to be activated (and the Protection LED to go on)

whenever the operating temperature of the unit rises above a safe level. To

guard against this problem, make sure the S1500 / S2000 receives adequate

ventilation on all sides and that both the front and rear panels are unobstructed.

• Severe overcurrent conditions: This occurs whenever the signal being input to

the S1500 / S2000 rises to a level above 20% THD (Total Harmonic Distortion).

• Shorted speaker cables: This will occur if, due to faulty wiring, the hot and

ground signals being output by the S1500 / S2000 short one another.

• Output impedance drops below 2 ohms: This can occur if the S1500 / S2000

is connected to inappropriate speaker systems (see the "Setting Up and Using

Your S1500 / S2000" section on page 5 in this manual for more information).

• DC voltage detected at speaker output: The most likely cause of this is an

internal failure.

In general, any time the Protection LED lights up (other than during the

approximately five seconds following initial power-up), there is reason to be

concerned. If this occurs, turn the S1500 / S2000 off immediately and carefully

check all wiring and external devices in order to locate and correct the condition

that caused the LED to light up in the first place.

Hi there
To answer your question;
If it is not indicated near the fuse holder then look closely at the metal end caps of the fuse.
The value will be written on one of them,
It may look like 2A/250v for 2amps.

Hope this help
Cheers

There's a fuse input just underneith the mains input plug.A small screwdriver will open the small latch.You can get new fuses at Maplins.

Hi There,
Manufacturers install protection devices in their audio systems that are there for that purpose, any loud 'thump' or 'crack' trips the protection device so the loud speaker wont be burnt out. Speakers are expensive so the manufacturer does his best to allow you to listen to very loud sound and yet provided protection in case you exceed the sound rating of the output protection device.
In your case it sounds like the protection device has done its job but has not reset, to allow more listening...
Check the operational manual that came with the amp system to see if there are re-set instructions available to you....
If you dont have the reset detail, then phone/e-mail the manufacturer to obtain the reset information...

If there is no resetting you can do as a consumer then it should be no problem for a service shop to do the reset for you...
It may be a simple internal fuse that has blown but if its not accessible from the outside then I dont suggest you go inside and make changes unless you are skilled and trained in electronic servicing...

Cheers for now YUBEUT
