This auction is for a GR Type 1560-P40 Microphone-Preamplifier and microphone capsule. This can be used in a stand alone application or it can be used on a GR sound analyzer such as a 1654. For use w/o a GR instrument it requires about 8 to 15 volts to operate the preamp. This uses a 3 pin XLR connector. Pin 1 is ground. Pin 2 is the DC power(+ 8 to 15v or so) and pin 3 is the preamp output. I tried this out and it works fine. Shipping will be for 2 lbs. by UPS or USPS Priority Mail I'll ship overseas(inc. HI and AK) via USPS Priority Mail International California residents must add 8.00% sales tax.

For example, in connection with telephone and hearing aid testing. It is prepolarized, which enables connection to CCLD input conditioning. Uses· ... moreCoupler measurements· Hearing aid testing· Telephone testing· Connect to CCLD input Features· Sensitivity: 12.5 mV/Pa· Frequency: 8– 10 000 Hz· Dynamic range: 17.5– 160 dB· Temperature: 30 to 125˚C( 22 to 257˚F) Polarization: 0 V Use of pressure-field microphones For measurements to be made in small. Closed couplers or close to hard reflective surfaces, a pressure-field microphone is the best choice. An application that illustrates such usage is where a set of pressure sensing microphones are positioned at different points across an aircraft wing. A complete picture of the pressure variations across the wing surface can then be established. Pressure-field A pressure-field is characterised by a sound pressure that has the same magnitude and phase at any position within the field. Microphone Pressure Sensitivity refers to this type of field. Pressure fields can be found in enclosures or cavities that are small compared to the wavelength. Such fields occur in couplers applied for testing of earphones or calibration of microphones. They also occur in most types of sound level calibrator and in pistonphones. Robustness.

General Radio Type 1560-P40 Preamplifier& Microphone Tip For sale- a General Radio Type 1560-P40 Preamplifier and Microphone Tip. I guess that is an apt description. I think the 1560-P40 is just the long cylindrical part and the actual microphone plugs onto the end opposite the XLR connection. BONUS! I have four preamps with microphone tips installed. Plus an additional four microphone tips, so I will include an extra tip at no extra charge. Four of each are pictured. Price is for one and one. I don’t see what I would consider to be a model number on the microphone tip anywhere. There are numbers but I think they are serial numbers rather than model numbers. And in fact they may not be a microphone at all. If that is the case you have my apologies. But they certainly look like microphones. And GenRad or GR as they are often referred to ... moredoes produce microphones as well as acoustic test instruments. So it isn’t much of a stretch to call them what I think(as opposed to what I know) they are. None of the microphones has been tested. And NO warranty is offered. However. IF you pay the asking price and find it has a problem you cannot live with within 14 days of receipt you may return it. Returns are ONLY allowed on Buy It Now Purchases. Accepted Best Offers are strictly an as is sale. No returns allowed. Return would be for a refund of the purchase price. Not including shipping costs. Just so that we are clear on that. This is an item that has not been thoroughly tested. As such it may work fine or it may have problems. So any purchase entails a certain degree of risk. If you Buy It Now your risk is limited to the shipping costs both ways. If you submit an offer you do so knowing that you cannot return it. In either case it is up to you to decide whether the risk level is acceptable to you. And if not you need to pass on this particular item. If you pay the asking price I can probably throw in an XLR cable. But I can’t guarantee you what shape it will be in. Please check out my other listings for more interesting

Such as Brüel& Kjær Types 4144 and 4145. And ½" diameter Types 4165 and 4166, provide for the majority of noise measurements to IEC, IS0 and ANSI standards. However, for measurements around the 20/1Pa reference pressure, a very low noise floor in the 1/3-octave bands between 20Hz and 20 kHz is needed. The microphone and preamplifier system, with a noise floor of typically-2,5dB(A) provides for this area without compromising the useful frequency range ... moreand omni-directivity of a microphone intended for precision measurements. With narrow-band analysis. The noise floor falls to approximately-16dB for 1/3- octave bandwidth at 1 kHz, and-34dB for 3,16Hz bandwidth at 1 kHz. The system is thus well-suited to both laboratory and industrial applications ranging from hearing research to the measurement of very-low-level machine noise. The system for very low-level sound measurements comprises Type 4179. The Type 2660 and a ½” to 1” adaptor DB-0375. Type 2660 is presented in a mahogany case designed with space for the Type 4179 and adaptor, so that the system may be stored together. Type 4179, also has its own mahogany case(which fits in the larger case) for separate storage when required. The microphone is supplied with its own calibration chart. And a plastic cover for protecting the diaphragm from dust when the microphone is not in use. Microphone Preamplifier Type 2660. While designed especially for use with Type 4179, may also be used with other microphones. It has a function selector which is set to“4179 +20dB” for Type 4179. And either“Lin. 0dB” or“Lin. +20dB” for other condenser microphones. It accepts ½" micro
