Text of the page (random words):
icrophones adjustments may be required to achieve compatibility between different manufacturers 37 the apple plaintalk microphone jack used on some older macintosh systems is designed to accept an extended 3 5 mm three conductor phone connector in this case the tip carries power for a preamplifier inside the microphone it cannot accept a standard microphone without a preamp if a plaintalk compatible microphone is not available the jack can accept a line level sound input normally 3 5 mm three conductor sockets are used in computer sound cards for stereo output thus for a sound card with 5 1 output there will be three sockets to accommodate six channels front left and right surround left and right and center and subwoofer 6 1 and 7 1 channel sound cards from creative labs however use a single three conductor socket for the front speakers and two four conductor sockets f this is to accommodate rear center 6 1 or rear left and right 7 1 channels without the need for additional sockets on the sound card some portable computers have a combined 3 5 mm trs toslink jack supporting stereo audio output using a trs connector or toslink stereo or 5 1 dolby digital dts digital output using a suitable optical adapter most imac computers have this digital analog combo output feature as standard with early macbooks having two ports one for analog digital audio input and other for output support for input was dropped on various later models 38 39 some newer computers such as lenovo laptops have 3 5 mm trrs headset sockets which are compatible with phone headsets and may be distinguished by a headset icon instead of the usual headphones or microphone icons these are particularly used for voice over ip video edit different length 3 5 mm trrs connectors equipment requiring video with stereo audio input or output sometimes uses 3 5 mm trrs connectors two incompatible variants exist of 15 millimetres 0 59 in and 17 mm 0 67 in length and using the wrong variant may either simply not work or could cause physical damage attempting to fully insert the longer 17 mm plug into a receptacle designed for the shorter 15 mm plug may damage the receptacle and may damage any electronics located immediately behind the receptacle however partially inserting the plug will work as the tip ring ring distances are the same for both variants a shorter plug in a socket designed for the longer connector may not be retained firmly and may result in wrong signal routing or a short circuit inside the equipment e g the plug tip may cause the contacts inside the receptacle tip ring 1 etc to short together the shorter 15 mm trrs variant is more common and physically compatible with standard 3 5 mm trs and ts connectors recording equipment edit stereo devices which use plug in power the electret capsules are wired in this way many small video cameras laptops recorders and other consumer devices use a 3 5 mm microphone connector for attaching a microphone to the system these fall into three categories citation needed devices that use an unpowered microphone usually a cheap dynamic or piezoelectric microphone the microphone generates its own voltage and needs no power devices that use a self powered microphone usually a condenser microphone with an internal battery powered amplifier devices that use a plug in powered microphone an electret microphone containing an internal fet amplifier these provide a good quality signal in a very small microphone however the internal fet needs a dc power supply which is provided as a bias voltage for an internal preamp transistor plug in power is supplied on the same line as the audio signal using an rc filter the dc bias voltage supplies the fet amplifier at a low current while the capacitor decouples the dc supply from the ac input to the recorder typically v 1 5 v r 1 kω c 47 μf if a recorder provides plug in power and the microphone does not need it everything will usually work ok in the converse case recorder provides no power microphone needs power no sound will be recorded pdas and mobile phones edit all iphone models from the first generation to the 6s and se first generation use a four conductor trrs phone connector center for a wired headset three or four conductor trs or trrs 2 5 mm and 3 5 mm sockets are common on older cell phones and newer smartphones respectively providing mono three conductor or stereo four conductor sound and a microphone input together with signaling e g push a button to answer a call these are used both for handsfree headsets and for stereo headphones 3 5 mm trrs stereo plus mic sockets became particularly common on smartphones and have been used e g by nokia since 2006 they are often compatible with standard 3 5 mm stereo headphones some computers now also include a trrs headset socket compatible with the headsets intended for smartphones the four conductors of a trrs connector are assigned to different purposes by different manufacturers any 3 5 mm plug can be plugged mechanically into any socket but many combinations are electrically incompatible for example plugging trrs headphones into a trs headset socket trs headset into a trrs socket or plugging trrs headphones from one manufacturer into a trrs socket from another may not function correctly or at all mono audio will usually work but stereo audio or the microphone may not work trrs standards edit two different forms are frequently found both of which place left audio on the tip and right audio on the first ring for compatibility with stereo connectors where they differ is in the placement of the microphone and return contacts the first which places the ground return on the sleeve and the microphone on the second ring is standardized in omtp 40 and has been accepted as a national chinese standard ydt 1885 2009 it is mostly used on older devices such as older nokia mobiles older samsung smartphones and some sony ericsson phones 41 and products meant for the chinese market 42 43 headsets using this wiring may be indicated by black plastic separators between the rings 44 43 the second which reverses these contacts with the microphone on the sleeve is used by apple s iphone line until the 6s and se 1st and has become the de facto trrs standard to maintain compatibility with these products 45 46 47 it is now used by htc devices recent samsung nokia and sony phones among others this is referred to as ctia ahj and has the disadvantage that the mic will be shorted to ground if the body of the device is metal and the sleeve has a flange that contacts it headsets using this wiring may be indicated by white plastic separators between the rings 44 43 if a ctia headset is connected to a mobile phone with omtp interface the missing ground will effectively connect speakers in out of phase series resulting in no voice on typical popular music recordings where the singers are in the center in this case if the main microphone button is held down shorting across the microphone and restoring ground the correct sound may be audible 43 standard tip ring 1 ring 2 sleeve devices using this standard ctia ahj left audio

both ctia and omtp yd t 1885 2009 modes 60 some devices transparently handle many jack standards 61 62 and there are hardware implementations of this available as components 63 this is accomplished in some cases by applying a voltage to the sleeve and second ring to detect the wiring the last two conductors may then be switches to allow a device made to one standard to be used with a headset made to the other 64 trrrs standards edit new trrrs standard for 3 5 mm connectors was developed and recently approved by itu t 65 the new standard called p 382 formerly p mmic outlines technical requirements and test methods for a 5 pole socket and plug configuration compared to the legacy trrs standard trrrs provides one extra line that can be used for connecting a second microphone or external power to from the audio accessory p 382 requires compliant sockets and plugs to be backwards compatible with legacy trrs and trs connectors therefore p 382 compliant trrrs connectors should allow for seamless integration when used on new products trrrs connectors enable following audio applications active noise cancelling binaural recording and others where dual analogue microphone lines can be directly connected to a host device it was commonly found on sony phones starting with the xperia z1 xz1 and xperia 1 ii switch contacts edit this section does not cite any sources please help

jacks all are 3 5 mm except the gold plated plug which is 2 5 mm one of the 3 5 mm jacks is two conductor and the others are three conductor in this collection the tan colored jacks have normally closed switches panel mounting jacks are often provided with switch contacts most commonly a mono jack is provided with one normally closed nc contact which is connected to the tip live connection when no plug is in the socket and disconnected when a plug is inserted stereo sockets commonly provide two such nc contacts one for the tip left channel live and one for the ring or collar right channel live some designs of jack also have such a connection on the sleeve as this contact is usually ground it is not much use for signal switching but could be used to indicate to electronic circuitry that the socket was in use less commonly some jacks are provided with normally open no or change over contacts and or the switch contacts may be isolated from the connector the original purpose of these contacts was for switching in telephone exchanges for which there were many patterns two sets of change over contacts isolated from the connector contacts were common the more recent pattern of one nc contact for each signal path internally attached to the connector contact stems from their use as headphone jacks in many amplifiers and equipment containing them such as electronic organs a headphone jack is provided that disconnects the loudspeakers when in use this is done by means of these switch contacts in other equipment a dummy load is provided when the headphones are not connected this is also easily provided by means of these nc contacts other uses for these contacts have been found one is to interrupt a signal path to enable other circuitry to be inserted this is done by using one nc contact of a stereo jack to connect the tip and ring together when no plug is inserted the tip is then made the output and the ring the input or vice versa thus forming a patch point another use is to provide alternative mono or stereo output facilities on some guitars and electronic organs this is achieved by using two mono jacks one for left channel and one for right and wiring the nc contact on the right channel jack to the tip of the other to connect the two connector tips together when the right channel output is not in use this then mixes the signals so that the left channel jack doubles as a mono output where a 3 5 mm or 2 5 mm jack is used as a dc power inlet connector a switch contact may be used to disconnect an internal battery whenever an external power supply is connected to prevent incorrect recharging of the battery a standard stereo jack is used on most battery powered guitar effects pedals to eliminate the need for a separate power switch in this configuration the internal battery has its negative terminal wired to the sleeve contact of the jack when the user plugs in a two conductor mono guitar or microphone lead the resulting short circuit between sleeve and ring connects an internal battery to the unit s circuitry ensuring that it powers up or down automatically whenever a signal lead is inserted or removed a drawback of this design is the risk of inadvertently discharging the battery if the lead is not removed after use such as if the equipment is left plugged in overnight design edit examples of jack configurations oriented so the plug enters from the right the most common circuit configurations are the simple mono and stereo jacks a and b however there are a great number of variants manufactured 66 a two conductor ts phone connector the connection to the sleeve is the rectangle towards the right and the connection to the tip is the line with the notch wiring connections are illustrated as white circles a three conductor trs phone connector the upper connector is the tip as it is farther away from the sleeve the sleeve is shown connected directly to the chassis a very common configuration this is the typical configuration for a balanced connection some jacks have metal mounting connections which would make this connection and some have plastic to isolate the sleeve from the chassis and provide a separate sleeve connection point as in a this three conductor jack has two isolated spdt switches they are activated by a plug going into the jack which disconnects one throw and connects the other the white arrowheads indicate a mechanical connection while the black arrowheads indicate an electrical connection this would be useful for a device that turns on when...
