  What is Mic level? Some mixers and active speaker have switches on the rear panel for setting each input jack or output jack for mic level (XLR) or line level (1/4″). These terms refer to the signal level or intensity. Microphone level is in the region of -60 dBV (0.001 volt) to -40 dBV (0.010 volt). (dBu and dBV are decibel measurements relative to voltage). The professional microphones output what is known as a Mic Level signal.Including moving-coil microphone and Condenser Microphone. This is a low impedance signal ranging typically from 200 ohm to 1000 ohm, nominal impedance 600 ohm, carried on a microphone cable with 3-pin XLR cable connectors. Mic level or microphone level signal is the voltage level that comes out of a microphone when someone speaks into it, typically just a few ten-thousandths of a volt. Of course, this voltage varies in response to changes in voice level and and in the talker-to-mic distance. But the signal is still quite small. Because of the

  About XLR Pinout (3-Pin, 5-Pin & 7-Pin) XLR connectors are used in audio (mic level & line level) and DMX lighting control (DMX) applications.                              3-Pin XLR and 7-Pin XLR Audio Pinout The following is the AES industry standard for balanced audio XLR wiring, commonly known as “pin-2 hot”. 3-Pin XLR connectors are standard amongst line level and mic level audio applications . The above diagram shows you the pin numbering for both Male and Female XLR connectors. 3-pin XLR Pinout: Pin1 = Shielding (Ground) Pin2 = Hot (Positive), + Pin3 = Cold (Negative), – 7-pin XLR Pinout: Pin1 = B+ Pin2 = Pattern Pin3 = 6 Volts Pin4 = Gnd Pin5 = Out Pin6 = Out Pin7 = Gnd                     3-Pin XLR and 5-Pin XLR DMX Lighting Pinout The ESTA standard known as Entertainment Technology USITT DMX512-A – Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories, also known as DMX512-A.

                  What is Line Level? A Line level is in the region of 0 dBV (1.0 volt), Line level signals have a much higher voltage output than mic or instrument level, usually somewhere around 750 millivolts.It is about 1,000 times as strong as a mic-level signal, so the two do not ordinarily use the same input. This signal travels from your pre-amp to the amplifier that powers your speakers. -10 dBV (0.316 V RMS) for consumer equipment (like MP3 and DVD players), +4 dBu (1.23 V RMS) for professional equipment (mixing desks and signal processing gear) . The 4 main connector types we see in line level audio, and in fact all of analog audio, are the 6.35mm jack, 3.5mm mini jack, RCA and XLR connector.     Connecting a line-level source (such as mixer output) to a mic-level input will cause the sound to be loud and distorted because the line signal is much stronger than what the mic input will accept. Inputs and outputs on many mixers are switchable for either mic or lin

  What is 5 pin DIN connector? A DIN connector is an electrical connector that was originally standardized in the early 1970s by the Deutsches Institut für Normung (DIN), the German national standards organization. A DIN connector encompasses several types of cables that plug into an interface to connect devices. It has an architecture that is composed of multiple pins that are within a protective circular sheath. Typically, a full-sized DIN connector has three to 14 pins with a diameter of 13.2 millimeters. In computer electronics, the DIN connector is referred to as a circular connector that is DIN standardized and used for digital interfaces like the musical instrument digital interface (MIDI), the IBM AT computer keyboard or mouse, and in analog video architectures. Original DIN standards for older connectors are no longer in print and have been supplanted with the corresponding international standard IEC 60130-9. There are seven familiar patterns with three to eight

  What is the S-video and PS/2 port? S-video (short for Super-video) is an older type of video signal that’s transmitted in varying electrical signals over wires to represent the original video. Newer video cables like HDMI transmit digital video signals in the form of numbers representing the original video signal. The benefit of digital video is that the signal doesn’t degrade from source to destination. It’s also capable of transmitting much higher resolution video. S-video is an improvement over composite video, which carries all the video data (including both brightness and color information) in one signal over one wire. S-video carries brightness and color information as two separate signals, over two wires. Because of this separation, video transferred by S-video is higher quality than that of composite video. The S-video cable transmits video through two synchronized signal and ground pairs, named Y and C. S-Video (4-pin) PS/2 port The PS/2 (Personal System/2) por

  What is the DMX512 lighting control cable (AES/EBU Digital audio Cable)? DMX cable signal is based on RS485 signal, a kind of industry-standard protocol after adjusting the transmit Baud rate. Usually there are one pair DMX512 lighting control cable and two pair DMX512 lighting control cable . Cable types that are appropriate for DMX512 usage will have a nominal characteristic impedance of 110(±22)ohms ,at frequencies from 0.1MHz to 128 times the maximum frame rate when measured at the output terminals. The signal amplitude shall lie between 2V and 7V peak-to-peak when measured across a 110 ohm resistor connected to the output terminals, without any interconnecting cable present.NOTE a typical value is 4V±10% . At the short distances, cables with higher capacitance and different characteristic impedance such as microphone cable can be used. However, the significantly lower impedance and higher capacitance of these cables distort the DMX512 digital waveforms, which in tur

  How to choose the right speaker wire/cable? The purpose of Speaker cable is the wire used for the electrical connections between amplifier sources and loundspeakers system.The transfer is accomplished through the low-voltage electrical current conducted through the wires.It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important property to look at. Today most loudspeaker systems have an impedance between 4 ohm and 8 ohm. As the resistance rises it starts to affect the system performance. Obviously there can be a reduction in the drive current to the loudspeaker as the voltage across the cable increases. The other issue is that the back EMF created by the loudspeaker needs to have a low impedance source against which to work. As the source impedance rises, so the back EMF is absorbed less. This affects the performance of the loudspeaker, particularly in the bass region where the bass may not be as pronounced

What is the advantage of low-capacitance cable? The propaudio ultra low capacitance cable lets you hear all the frequencies being produced by your guitar. High cable capacitance kills the high frequencies from your pickups, resulting in a muddy sound and the greater the signal loss. With cables that are paired, or coaxial, the two conductors with insulation or conductor and shielding in between form a capacitor, which holds an electrical charge. The electrical resistance of a guitar cable is insignificantly tiny compared with the impedance of the pickups and controls, so that won’t affect your tone a great deal, but cable capacitance is another matter altogether. A capacitor is formed whenever two electrical conductors are in placed in close proximity, and for a given spacing, the larger the surface area of the conductors, the larger the capacitance. The core and screen conductors of typical guitar cable may produce a capacitance of around 30 picofarads per foot (or 100
