Question about Fishman SA220 Solo Performance System Speaker PA Active

Open Question

My fishman solo amp has started making a static hissing noise when i turn it on. Does this with or without mics conected.

Just started having static in the background when i turn it on. Its a constant noise that is very noticeable when volume is turned up. Turning the base all the way up and treble all the way down helps some but its still there.

SOURCE: where is the fuse located in the fishman solo amp

The fuse is inside and if it blows, there is something wrong that caused the failure and MUST be repaired as just changing the fuse MAY do additional damage.

SOURCE: Low volume from Fishman Loudbox

I have seen defective XLR cables so check it with an ohmmeter. It is possible the mic input preamp has been damaged. If that is the case, the unit will have to be repaired.

Mpc 1000 loud static


Maybe try adjusting the MASTER level?

Good Luck

Other settings
Adjusting the master level You can adjust the level of the headphone and the stereo out by turning the MAIN VOLUME knob. The MAIN
VOLUME changes the analog signal level. This will also adjust the entire level of the MPC1000 digitally.
01. Press the [MODE] key and then the [PAD 10] (OTHER).
It switches to the OTHER mode.
02. Press the [F1] (GLOBAL) key.
The GLOBAL page will be displayed.
03. In the Master level field, set the level.
You will set the digital signal level, which will be sent out to the DA converter. The MPC1000 can output up to
32 sounds simultaneously. There is the great difference in the level when you play single sample and play 32
sounds. If you increase the value in the Mater level field, you can increase the entire level of the MPC1000 to
create more powerful sound with less noise. However, if you playback many sounds at the same time, the
level may be overloaded, which may cause distortion. If you decrease the value in the Master level field, you
can prevent distortion when you play many sounds at the same time. However, you cannot have a good
result in respect to the noise or punch of the sound. Set the appropriate value in the Master level field
depending on the application.

I had major static sounds from my yamaha stagepas 500. I plugged in an acoustic guitar into the mixer while running a keyboard and 2 vocal mics. I started getting crackling sounds. I changed the patch...


Chances are there is nothing wrong with the mixer. IF you accidentally turned on Phantom power, that would cause the problem. Phantom is ONLY used with condenser mics and a few DI boxes. Turning it on can create noise unless balanced lines are used everywhere.

I feel that the 'normal' background hiss is a problem that I would like to minimize with the sennheiser IEM 300. I'm currently using the IE 4 ear phones. Would a different/better earset with maybe a...


No, that will not help. The his is a function of the receiver NOT receiving a signal from the transmitter as they apparently do NOT have a "squelch" circuit to mute the receiver noise when no signal is being received. The noise level when no signal is received is pretty high and apparently the volume control is not enough to reduce the hiss.

To solve this, LEAVE the transmitter ON and make yourself a switch at the receiver. DO this using one of those little in line lamp switches that fit on zip cord. Make one on a short length of zip cor with mating connectors to fit the received jack and the headphone plug. Don't worry about unshielded wire as the impedance is very low. Then you use this switch to mute the headphones when you want to. There are other switch types you can use, I am just suggesting what might be readily available to you.

Sennheiser SHOULD have include a mute switch on their unit as turning the power off on the receiver would be a pain. They could have used a volume control with switch to kill the audio line out... simple solution... oversight on their part.

Fender Hot Rod Deluxe Volume Fluctuations. My amp (fender hot rod deluxe) will occasionally have volume fluctuations when I'm playing. The changes usually occur when I've moved my setup from one place...


First thing would be try another guitar with the amp. This will eliminate if it's a problem with the guitar or the amp itself. If the guitar is working properly then check all the tubes to be sure they are all seated into there slots completely. Depending on how much use they have been played it may be a good suggestion to then replace your tube's. Occationally the tubes will start loosing power, making sound fluctuate up and down or distortion sounding static in background noise. You will notice a big difference with newer tube. But remember the bias must be set correctly to match the new tubes so they won't over heat. You can check out youtube for setting the bias. Anyway this is my suggestion and I wish you good luck.

I have a behringer xenyx 1204usb mixer with a mxl 990 mic and i have problems with static. thats all i have hooked to the mixer so i dont think its a conflict. i have tried recording in audition, pro...


Yep ! First thing is to eliminate any processing resource "hogs" that **** respources and can cause buffer overruns. Eliminate Antivirus, antispyware, and network communication and wireless network programs running in the background while recording.
Next make sure that ALL equipment is powered from the same receptacle or power source. In your case that should be the mixer and the PC.
Next remember that the condenser mic picks up everything... I have 5 of those mics and seemingly noise free environments turn out to have little things that generate fast rising pulses that you don't notice till they are recorded.
Lastly, the air here is very dry and plain old static electricity is rampart... Lady shuffling her feet was sending pulses through the mic cable at our church. They are NOT audible until they get into the sound system as clicks.
I have found that trying to record directely to a USB stick often has ooverruns and clicks... also burning a CD from stick to the CD results in noise due to buffer underuns. Burn from Hard drive to CD and make sure all the other hog programs are shut off.

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?


I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

My xp-50 is emitting a noise when the keys are pressed


If the level is very low, this is what is known as "digitizing noise".

The waveforms from synths being digital in nature, have sharp edges that are filtered. There is a fine line between filtering too much and too little.

There is ALSO the statistical noise that is present in electronic devices that you can notice when you turn the volume way up.

These are all NORMAL and the nature of the beasts.

What causes the static background noise in my keyboard?


Hi,

It sounds as though you have a static electricity problem in your volume pot. Although there are sprays on the market that you can use for all of the electrical switches on your keyboard which removes and suppresses static electricity, one way to make sure this is the problem is to slide your volume slider to maximum, then minimum, up and down about 10 to 20 times, if the scratchy sound begins to diminish, you knwo the problem lies there. As a matter of fact, if you do it long enough, the sound may go away altogether, although without a good spray of electronics cleaner or electrical contact cleaner (which you can find at stores like home depot or online, even eBay), the sound will return.

If this is not the case, and the scratchy static sound does not go away or depreciate, it could be your cords or even static on the pc board inside the unit. If you are confident that you can crack the case on your board without causign damage, then get a screwdriver and open the case (all screws are located on teh bottom of the unit) and give it a good spraying with electrical contact cleaner on all of the contacts and even a once over on all of the circuit boards. Do not wet the circuit boards with too much spray, rather, give them a light misting.

For areas where you plug in, like your 1/4 inputs, your midi ins and outs, and headphone jack, spray the contact cleaner inside the holes. You don't have to worry about spraying too much in these areas. Just do not oversaturate.

Hope this helps, and thanks for using FixYa

Alesis SR-16 distorted sounds


The distorted and low volume output plus noise is usually caused by using the wrong power supply adapter. The Alesis SR-16 takes a 9V "A/C" supply not "DC". The A/C supply provides a negative voltage swing which wouldn't exist with a DC supply. So check and make sure you have 9V A/C output supply not DC.
