Aug 10, · Yes, generally you plug into a PA (public address) system that consists of an amplifier and speakers. Most of today's professional singers also use .
Microphones typically produce fairly low output levels. Therefore, a microphone always requires a preamp that amplifies its low level output to line level. Most audio interfaces already have built-in preamps, which are usually good enough to get started.
You may want to get an external preamp for better sound quality, later on. The how to cut a book into art is absolutely crucial: The XLR part is for microphones, the TRS part is either for line sources or instruments, but not for microphones.
If you plugged your mic into the TRS input, it would either be noisy or not work at all. You can access the microphone preamp only via the XLR input. Condenser microphones require external power for their internal electronics. The international standard is P48 phantom power a Neumann invention, by the way. Just about any microphone w, these days, is equipped with phantom power. Sometimes there is a global switch for all microphone inputs; more expensive devices often come with individual P48 switches for each input.
As a general rule: Always connect your mic s first, before you turn on phantom power. Hot plugging while P48 is already activated can harm your mics. Also, never put anything between your mic and your microphone input. Also, puttting mic inputs on a patchbay is not recommended. Always connect your mic directly to the XLR mic input. Dynamic microphones, i. As long as everything is wired correctly, phantom power does not affect dynamic mics, at all.
A studio microphone operates with a balanced output: There are three pins: hot, cold and ground. The signal is between hot and cold; ground is connected to the cable shield. Phantom power is a DC voltage, whose positive side is applied to both signal pins. Sounds like a lot, but it is not micropohne, really: The voltage is applied via large resistors 6. Never put an XLR plug into your mouth, though! Even a 9V battery can potentially kill you, if you put it to your wet tongue.
Many audio interfaces come with combo jacks. For microphones, always use the XLR part, the TRS part is either for line signals or for instruments such as guitar or bass. Phantom Power: The positive side is applied to both signal lines via two resistors R2. More Know-How. TLM A true Neumann at an affordable price.

Choosing the Correct Input
All you have to do is press the button labeled “P48”, “48V”, or “Phantom Power”. Sometimes there is a global switch for all microphone inputs; more expensive devices often come with individual P48 switches for .

Dec 28, · Connect the microphone cable to your mixer/preamp at input one. You may have a "line" or "mic" switch above the volume knob or slider. Use the "mic" position. The "line" position is normally used for music sources such as a CD or Cassette player.

Aim the speakers so that the left speaker covers the left side of the audience and the right side speaker covers the right side of the audience. This is for mono use. If you choose stereo, you'll need two sound sources such as a left and right channel of music.
One microphone should always be hooked up mono. Place your single cardioid microphone on its stand where you plan to place the person speaking but never in front of the speakers. When you place the microphone in front of the speakers, your chances of producing feedback that squealing sound are greatly enhanced. A microphone placed behind the sound system has a much better chance of rejecting feedback. The cardioid microphone is another name for a directional microphone.
Its pick up pattern is directed away from the back of the mic and helps to reduce feedback as well. Another type of mic would be an omni which has a pickup pattern that's close to equal in front and in back of the mic. Not a good mic for preventing feedback in your system. You may have a "line" or "mic" switch above the volume knob or slider. Use the "mic" position. The "line" position is normally used for music sources such as a CD or Cassette player.
If you have a gain control knob, sometimes called trim above the slider or volume knob, set it at halfway for now. It's a good starting point to allow enough signal into this input and should keep you from "overloading" the input from too much signal.
If there is no mono input on your amplifier, you may use the left channel of the amp to drive both speakers assuming you have enough power in the amp or "Y" the Left and Right inputs to the amplifier. This means that the mono out of the preamp is "Y" connected to both left and right amplifier inputs. Set the amplifier volume controls to minimum until we get a good level coming out of your preamp. Connect the output channels of your amplifier to the left and right speakers.
Keep cables neat and taped down. They are easy to trip on and cause injury to someone. Now that you're all connected, you can set levels. Take the mic and talk normally into it. Watch the meter on the preamplifier as you raise the slider or volume knob up slowly. Raise the input one control until you reach the maximum allowable setting on your meter. If you get into the red, lower your gain setting on the "input gain" knob. Never run your input way down low and your master way up high. This will only overload your console and give you distorted sound.
Your meters should "Peak" at 1 or 2 or just when the first red LED lights up. When you go higher, your asking for distortion or that "fuzzy" sound in the speakers. When you've got your proper settings on the preamplifier, slowly turn your amplifier volume controls up until a good listening volume is achieved.
If your mic goes into feedback, lower the volume or move the mic further away from the speakers. It depends. If it is XLR then you'll need a microphone interface. Yes No. Not Helpful 1 Helpful 7.
