| Connector Type | |||
| Your choices are... | |||
| BNC | The "Bayonet Neil-Concelman" or "Bayonet Navy Connector" or "Baby Neil Connector," depending on the information source. Karl W. Concelman is believed to have created the "C" connector. The BNC was designed for military use and has gained wide acceptance in video and RF applications to 2 GHz. The BNC uses a slotted outer conductor and some plastic dielectric on each gender connector. This dielectric causes increasing losses at higher frequencies. Above 4 GHz, the slots may radiate signals, so the connector is usable, but not necessarily mechanically stable up to about 10 GHz. Both 50-ohm and 75-ohm versions are available. | ||
| XLR Connector | XLR type connector, 3-pin, balanced. | ||
| 1/4'' Phone Plug | 1/4" Phone jacks are essentially connectors used in audio systems: audio cables, amplifiers, speakers, etc. The diameter of the jack is 0.25". | ||
| 1/8'' Phone Plug | 1/8" Phone jacks are essentially connectors used in audio systems: audio cables, amplifiers, speakers, etc. The diameter of the jack is 0.125". | ||
| Modular Connector | Typically an RJ or 4P4C connector usually used with telephone handsets. | ||
| USB | USB connectors are used with universal serial bus (USB) ports. They can be used to connect USB products together, or to connect USB wires and peripherals to other standard port types. | ||
| RCA | RCA Connectors are round, press-on connectors commonly used for consumer-grade audio and composite video connections. In most recent home stereo equipment, the jacks are color-coded as follows: red (audio-Right), black or white (audio-Left) and yellow (composite video). | ||
| Other | Other unlisted, specialized, or proprietary connector. | ||

| Sound Pressure Level | Sound pressure level (SPL) that the device can deliver. This is a rating provided by the manufacturer that may correspond to a maximum or nominal SPL at a certain frequency within the dynamic range. Value is given in decibels, typically in dB(A) or using the A-weighted value. Specification frequencies and conditions can be found on the manufacturer product data sheets. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Nominal Input Power | Typical design power used for driving the device. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Impedance | Input impedance for a device is optimally matched to the output impedance of the driving amplifier for most efficient and truest sound replication. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Frequency Response | The frequency response, or dynamic range, is the range of frequencies over which the device will operate while still meeting its performance specifications. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Dynamic Range | Dynamic range is the range of sound pressure levels (dB) for which the device will meet its performance specifications; it is limited on the low end by the inherent noise of the acoustic system and on the high end by the maximum sound pressure level. The standard unit for measuring sound pressure level (SPL) is the decibel (dB) with a reference pressure of 20 micro Pascals (20 μPa), which is the human hearing threshold. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Weight | Weight of the device, including any enclosure or attached features. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

|
| ||
| Frequency Response | Frequency response is the range of frequencies for which the device maintains a constant sensitivity within defined boundaries. Variation from this "linear" or "flat" sensitivity is given in dB; bounds that the define the linear frequency response will be in the form of ±3dB, -1dB/+4dB, etc. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Dynamic Range | Dynamic range is the range of sound pressure levels (dB) for which the device will meet its performance specifications; it is limited on the low end by the inherent noise of the acoustic system and on the high end by the maximum sound pressure level. The standard unit for measuring sound pressure level (SPL) is the decibel (dB) with a reference pressure of 20 micro Pascals (20 μPa), which is the human hearing threshold. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Microphone Sensitivity: | Measure of how responsive or "hot" a microphone is. Sensitivity may be given in millivolt output per Pascal of sound pressure, or may be specified in dBV (dB), in which case it is typically a negative number. A correctly specified signal should exceed the inherent noise of the system yet not overload the preamplifier. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Impedance | Impedance is the resistance to flow of alternating current. Low impedance microphones exhibit values such as 100-500 ohms, whereas high impedance microphones can be 10,000 ohms or more. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
