An amplifier is\nused to enhance sound signals. It is electrically powered and operates when\nconnected to a power supply. The amplifier increases the amplitude of a signal.\nThey are necessary when sound needs to be transmitted in a large room. This is\nquite difficult to accomplish with some speakers.<\/p>\n\n\n\n

Preamplifiers are devices that transmit strong output signals to amplifiers. They do this by converting a weak signal into the strong output signal. As such, the output signal is supposed be strong enough to be noise-tolerant. Without it, the noise will be deafening. Therefore, the preamplifier produces strong output signals which are used to amplify sound by the amplifier. <\/strong><\/p>\n\n\n\n

The Difference Between A Mixer And An Amplifier?<\/strong><\/h2>\n\n\n\n

Mixers are\ndevices used to combine different sound signals. This is done to produce one\ncoherent sound. The coherent sound is then sent to the amplifier as a signal.\nMixers can have inputs such as microphones which are used by singers. They are\nused in many applications. Some of them are;<\/p>\n\n\n\n

• Sound\nreinforcement systems Nightclubs<\/strong><\/li>
• Recording\nstudios<\/strong><\/li>
• Public\naddress systems<\/strong><\/li><\/ul>\n\n\n\n

  There are so\nmany others in which mixing consoles are used. They are very common especially\nin areas of entertainment. Mixers are very important in developing the desired\nsound. It is used to convert and mix different sound signals into one seamless\nand perfect sound.<\/p>\n\n\n\n

  On the other\nhand, amplifiers are needed to enhance sound signals to further distances. When\nentertaining many people some speakers, are not able to transmit the sound\nsignal to everyone. Amplifiers are therefore needed to get the job done. They\nreceive the needed sound signals from the mixer. Then, they amplify the sound\nsignal to reach further areas<\/p>\n\n\n\n

  The main\ndifference between the mixer and the amplifier is that; the mixer is used to\ncombine two different sound signals to produce one seamless signal. While the\namplifier is used to increase the sound signal reach further areas.<\/p>\n\n\n\n

  What Is\nThe Use of an Audio Amplifier?<\/strong><\/h2>\n\n\n\n

  An audio\namplifier is used to increase the power of a signal. The signal is a\ntime-varying current or voltage it is a two-port electronic circuit that uses\nan electronic power supply. The power supply is used to increase the amplitude\nof the signal. It therefore produces a generally more powerful signal at its\noutput. The amount of amplification is given by its gain. The gain is the ratio\nof the output voltage to the input. The power gain of an amplifier is usually\nmore than one.<\/p>\n\n\n\n

  An amplifier\ncan be an independent device on its own. It can also be within a certain piece\nof equipment. Amplifiers are very important in today\u2019s modern days. It is\ntherefore widely used in very many technologies. Amplifiers are therefore\nessential in sending sound signals in far areas. Therefore, they come in handy\nin enhancing the audio experience, especially when sound is needed in further\nareas.<\/p>\n\n\n\n

  What Does\na Pre Amplifier Do?<\/strong><\/h2>\n\n\n\n

  A preamplifier converts weak signals into strong output signals. The output signal must feature enough strength for a noise-tolerant output. It should also be strong enough to be processed by a speaker or a power amplifier. The preamplifier is important or else the sound will be too loud or distorted. What it mostly does is to amplify the signal from analog sensors. It is also placed close to these sensors to prevent the effects of interference and noise.<\/p>\n\n\n\n

  An ideal\npreamplifier should have a constant gain, high input impudence and low output\nimpudence. It is used to increase signal strength without degrading the signal\nto noise ratio. The noise performance of a preamplifier is quite critical. When\nthe gain is high, the sound to noise ratio (SNR) of the input signals\ndetermines the SNR of the output signal. It is also determined by the noise\nfigure of the preamplifier.<\/p>\n\n\n\n

  How to\nConnect a Mixer to an Amplifier and a Pre Amplifier<\/strong><\/h2>\n\n\n\n

  The following\ncan be done according to the following processes;<\/p>\n\n\n\n

  1. The mixer and the\namplifier should be off. This prevents shot-circuiting the devices.<\/li>
  2. Connect the plugs on\nthe end of the stereo cable then connect the white plug in the left jack and\nthe red plug in the right.<\/li>
  3. Insert the plugs on\nthe other end of the amplifier.<\/li>
  4. Turn on the equipment\nand set the amplifier selector knob.<\/li><\/ol>\n\n\n\n

     Later the\namplifier can be connected to the preamplifier as follows;<\/p>\n\n\n\n

     1. Inspect your equipment\nto be sure of compatibility.<\/li>
     2. Connect the cords of\nthe amplifier and the preamplifier into the designated plug-ins.<\/li>
     3. Plug one end of every\nconnector cable into the output plugs on the back of the preamplifier.<\/li>
     4. Connect the cable’s\nother end into input plug holes of the amplifier.<\/li>
     5. Connect your source\nequipment to the preamplifier\u2019s input plug-ins, and connect the speaker\u2019s to\nthe amplifier.<\/li><\/ol>\n\n\n\n

        Connecting\nMixer to Amp to Speakers<\/strong><\/h2>\n\n\n\n

        The mixer\nshould first be connected to the amplifier as follows;<\/p>\n\n\n\n

        1. The mixer and the\namplifier should be off. This prevents shot-circuiting the devices.<\/li>
        2. Connect the plugs on\nthe end of the stereo cable. (The white plug should be connected in the left\njack and the red plug in the right).<\/li>
        3. Insert the plugs on\nthe other end of the amplifier.<\/li>
        4. Turn on the equipment\nand set the amplifier selector knob.<\/li><\/ol>\n\n\n\n

           After\nconnecting the mixer to the amplifier, the amplifier should then be connected\nto the speaker in the following ways;<\/p>\n\n\n\n

           1. On the back of the\namplifier, one should look for the speaker inputs.<\/li>
           2. Connect your speaker\nwires to these outputs, one on each output.<\/li>
           3. The speaker wires are\nusually just bare wire ends. Make sure the left and right output speaker wires\nare connected to their corresponding left and right speakers. <\/li><\/ol>\n\n\n\n

              Mixer to Amp Cable<\/strong><\/h2>\n\n\n\n

              This process is\neasily broken down into four easy steps as follows;<\/p>\n\n\n\n

              1. The mixer and the\namplifier should both be turned off. This helps in preventing the\nshort-circuiting of the devices.<\/li>
              2. Connect the plugs on\none end of the stereo cable to the audio jacks on the mixer. (The white plug is\nto be connected to the left audio jack and the red plug to the right).<\/li>
              3. Insert the plugs on\nyour other end into the amplifier\u2019s audio jacks.<\/li>
              4. Turn on the equipment\nand set the amplifier selector knob to the set of audio jacks connecting it to\nthe powered mixer.<\/li><\/ol>\n\n\n\n

                 Conclusion<\/strong><\/h2>\n\n\n\n

                 The amplifier\nand the preamplifier might seem to be similar devices because of their\nsimilarities in names. However, that is not the case. These two devices have\nproved to have to independent roles. Moreover, there is no device which is more\nimportant than the other. They are all very important in providing the ultimate\naudio experience. When both device are used correctly and connected well, the\noutcome will be one that will never be forgotten.<\/p>\n\n\n\n

                 Those that use\nthese devices in their everyday lives are witnesses that these devices are\nincredible. They should all be appreciated for their importance.<\/p>\n","protected":false},"excerpt":{"rendered":"
