Question about Shure 520DX Professional Microphone

Open Question

520DX cable noise

The cable is quite noisy when handled & not a short but acting like a piezo transducer....apparently there is something called resistive termination that can correct or eliminate the problem? I don't know how to go about this procedure/process

Makes large thumping/chirping noise when turned on. Its not even connected to the receiver


Since you have said the speakers make this sound when "turned on", I'm going to assume there's some form of power amplifier attached (internal, external or otherwise). Based on the minimal information provided here, this simply sounds like the normal reaction of a speaker when the amplifier is turned on. In short, an audio speaker is a type of "transducer" and when power is applied (thru some form of amplifier), the cone reacts to the power surge and causes a thump, pop or other noise. Turn on your TV for example and you'll usually hear a small pop from the speakers...and a larger/more powerful amplifier is likely to make a louder noise. Without further information, in most cases this is quite normal.

Assuming there is an external power amplifier, my advice would be to turn the volume on the amp (regardless of whether there's a receiver connected) to 0 before turning the power on. If it still makes such a noise, it's possible the volume control of the amp may require cleaning.

Good Luck!

My humminbird 898c is stuck on the loading screen, won't turn off or anything, any ideas?


First steps (you may have done done) check all wiring connections ,transducer, power,ext. at both ends. Attempt power up again. No change. Call 1-800-633-1468 with model & serial #'s. OR Disconnect all cable connections from unit and with a strip of aluminum foil short out all the connections on the 898c.(not the cable). Attempt power up again. If unit will let you go to 'System Status' screen & record. Hope your unit works.

How do i install backup alarm


You could get a 12 V sonalert from supply house like Newark:

MALLORY SONALERT SC628 TRANSDUCER PIEZO 2 9KHZ 80DBA 28VDC
it's $20 and works from 6 to 28 VDC.
Just wire it to the car's backup lights and you're set.

Parker fly acoustic pickup quit. When the red button is depressed all my gain is gone from the magnetic pickups and from the acoustic pickup.


If you are using a mono (2 contact) guitar cable then the output from magnetic & piezo pick-ups should be mixed together. If you are using a stereo cable (3 contacts - tip, ring sleeve) then it will be stereo with one signal sent down each core of the cable with common/ground on the sleeve.
If you are using a stereo cable into a mono amp socket it is possible that a short is occurring, which would cut the signal. I would also check your cable for poor/ shorting connections. The signal level could also drop if the pick-ups were out of phase with each other.
For more information on balancing the levels between the pick-ups see the user's manual here

Whenever I use one of the cleaner amp models i get an aggravating buzz. The buzz only occurs when I play and is not constant. (The buzz is not there when I'm not playing). At first I thought my strings...


Try moving your guitar around and oriented differently as it MAY be picking up magnetic fields from equipment in the area. Some pickups really are sentive to interference.

The effects for modeling MAY have a noise gate that requires a certain signal level before unmuting which would explain why you have to be playing to open the gate and hear noise that is really there all teh time but muted.

I just bought a Fender VF3 electric violin. It


The piezo pickups for violins REQUIRE a high impedance input preamp.

The measured impedance of My wife's violin is on the order of 2 megohms.

It sounds like you are having cable connection problems. If you don't have a preamp right at the vilin, then use a VERY short high impedance instrument cable.

Most of the Focusrite mic preamps I looked at had input impedance around 5K ohms which is unsuitable for the piezo pickups.

Here we use an Autolycus pickup on an acoustical vilin and an X2 wireless system. The transmiter has a very high input impedance and the resulting system sounds like a violin.

Some amps themselves DO have a high input impedance, but many designed for guitars do not. Long cables, especially low impedance ones, load the piezo pickup with capacitance which clobbers the high frequency response.

I bought a pick up for my violin. But when I plug it in and play. I get a rubbing sound coming through the speakers, like the pick up is picking up the bow strokes rather than just the notes... Its sounds...


Yes, and it will pickup "handling noise" as well.

A hint I can offer is to try a mute. One of the bent wire ones with weights that clips over the strings in back of the bridge..

I have found a perfect match for my wife's violin. We use an Autolycus pickup and an X2 wireless link. NOTE: the piezo pickups require a VERY high impedance input amplifier. You MUST use a very short cord or all the highs get wiped out.

We got the Autolycus from the source in New Zeeland (about $70). The fellow has a website with a sound clip. Search Google for Autolycus violin and you should find it. Do listen to the sound clip. The little piezo clips on the top where the sound post is with a plastic clip that reaches through the treble side F hole.

I had to make my own cable for the X2 wireless as it has a TRS 1/8 connector and the signal is on the ring and the tip and sleeve are ground. The Autolycus comes with an RCA jack on a pigtail. The X2 has a very high impedance input at the transmitter which is ideal for the Autolycus pickup. We use a Berhinger ACX1000 acoustic amp. It actually sounds like a violin.

Use good quality strings is important. The X2 system is a digital transmission at near CD quality.

One of the drum pads is disconnected. when i touch the wires it still makes a sound, but i can't seem to refit the pad into its place and it still functon


You might try taking the pad apart to see if the piezo transducer has come loose or if there is a bad connection at the transducer or the jack.

Annoying noise from inside my Vaio


I had the same problem with my Vaio, and I called in Sony Support and they called in a technician who came to my house in 2 days! Apparantly Sony got a batch of defective fans and if you are still under warranty they will replace it for free. Good luck!
