In a word: "noise." The whole point of balanced lines is noise rejection, and its something they're very good at. Any length of wire will act as an antenna to pick up the random electromagnetic radiation we're constantly surrounded by: radio and TV signals as well as spurious electromagnetic noise generated by power lines, motors, electric appliances, computer monitors, and a variety of other sources.The longer the wire, the more noise it is likely to pick up. That's why balanced lines are the best choice for long cable runs. If your "studio" is basically confined to your desktop and all connections are no more than a meter or two in length, then unbalanced lines are fine-unless you're surrounded by extremely high levels of electromagnetic noise. Another place balanced lines are almost always used is in microphone cables. The reason for this is that the output signal from most microphones is very small, so even a tiny amount of noise will be relatively large, and will be amplified to an alarming degree in the mixer's high-gain head amplifier. Balanced Noise Cancellation Signal Levels and the Decibel Let's take a look at one of the most commonly used units in audio: the decibel (dB). If the smallest sound that can be heard by the human ear is given an arbitrary value of 1, then the loudest sound that can be heard is approximately 1,000,000 (one million) times louder. That's too many digits to deal with for practical calculations, and so the more appropriate "decibel" (dB) unit was created for sound-related measurements. In this system the difference between the softest and loudest sounds that can be heard is 120 dB. This is a non-linear scale, and a difference of 3 dB actually results in a doubling or halving of the loudness. You might encounter a number of different varieties of the dB: dBu, dBV,dBM and others, but the dBu is the basic decibel unit. In the case of dBu, "0 dBu" is specified as a signal level of 0.775 volts. For example, if a microphone's output level is -40 dBu (0.00775 V), then to raise that level to 0 dBu (0.775 V) in the mixer's preamp stage requires that the signal be amplified by 100 times. A mixer may be required to handle signals at a wide range of levels, and it is necessary match input and output levels as closely as possible. In most cases the ''nominal" level for a mixer's input and outputs is marked on the panelor listed in the owner's manual. Microphones Use balanced lines. Short Line - Level runs Unbalanced lines are fine if you're in a relatively noise free environment Long Line - Level runs The ambient electromagnetic noise level will be the ultimate deciding factor, but balanced is best 1 www.PyleUSA.com Most professional mixers, power amplifiers, and other types of equipment have inputs and outputs with a nominal level of +4 dBu The Inputs and outputs on home-use audio gear usually have a nominal level of -7.8 dBu (-10 dBV). Microphone signal levels vary over a wide range depending on the type of microphone and the source. Avarage speech is about -30 dBu, but the twittering of a bird might be lower than -50dBu while a solid bass drum beat might produce a level as high as 0 dBu 2 www.PyleUSA.com To EQ or Not to EQ In general: less is better. There are many situations in which you'll need to cut certain frequency ranges, but use boost sparingly, and with caution. Proper use of EQ can eliminate interference between instruments in a mix and give the overall sound better definition. Bad EQ-and most commonly bad boost-just sounds terrible. Cut for a Cleaner Mix For example: cymbals have a lot of energy in the mid and low frequency ranges that you don't really perceive as musical sound, but which can interfere with the clarity of other instruments in these ranges. You can basically turn the low EQ on cymbal channels all the way down without changing the way they sound in the mix. You'll hear the difference, however, in the way the mix sounds more spacious," and instruments in the lower ranges will have better definition. Surprisingly enough, piano also has an incredibly powerful low end that can benefit from a bit of low-frequency roll -off to let other instruments-notably drums and bass-do their jobs more effectively. Naturally you won't want to do this if the piano is playing solo. The reverse applies to kick drums and bass guitars: you can often roll off the high end to create more space in the mix without compromising the character of the instruments. You'll have to use your ears, though, because each instrument is different and sometimes you'll want the snap of a bass guitar, for example, to come through. The fundamental and harmonic frequency ranges of some musical instruments Some Frequency Facts The lowest and highest frequencies than can be heard by the human ear are generally considered to be around 20 Hz and 20,000 Hz. respectively. Average conversation occurs in the range from about 300Hz to about 3,000 Hz. The frequency of a standard pitchfork used to tune guitars and other instruments is 440Hz (this corresponds to the "A3" key on a piano tuned to concert pitch). Double this frequency to 880Hz and you have a pitch one octave higher (i.e"A4" on the piano keyboard). In the same way you can halve the frequency to 220Hz to produce "A2" an octave lower. Boost with Caution If you're trying to create special or unusual effects, go ahead and boost away as much as you like. But if you're just trying to achieve a good-sounding mix, boost only in very small increments. A tiny boost in the midrange can give vocals more presence, or a touch of high boost can give certain instruments more "air." Listen, and if things don't sound clear and clean try using cut to remove frequencies that are cluttering up the mix rather than trying to boost the mix into clarity. One of the biggest problems with too much boost is that it adds gain to the signal, increasing noise and potentially overloading the subsequent circuitry. Fundamental: The frequency that determines the basic musical pitch. Harmonics: www.PyleUSA.com Multiples of the fundamentalfrequency that play a role in determining the timbre of the instrument. 3 4 www.PyleUSA.com Ambience Your mixes can be further refined by adding ambi· ence eflecls such as reverb or delay.The internal effects can be used to add reverb or delay to individualchannels in the same way as exlernal effects processors.(Refer to page 15). Reverb and Delay Time The optimum reverb time for a piece of music will depend on the music's tempo and density, but as a general rule longer reverb times are good for ballads, while shorter reverb times are more suited to up tempo tunes. Delay times can be adjusted to create a wide variety of ''grooves". When adding delay to a vocal, for example, try setting the delay time to dotted eighth notes corresponding to the tune's tempo. Reverb Tone Different reverb programs will have different ''reverb tone" due to differences in the reverb time of the high or low frequencies. Too much reverb, particularly in the high frequencies, can result in unnatural sound and interfere with the high frequencies in other parts of the mix. It's always a good idea to choose a reverb program that gives you the depth you want without detracting from the clarity of the mix. Reverb Level It's amazing how quickly your ears can lose perspective and fool you into believing that a totally washed-out mix sounds perfectly fine. To avoid falling into this trap start with reverb level all the way down, then gradually bring the reverb into the mix until you can just hear the difference. Any more than this normally becomes a "special effect". The Modulation Effects: Phasing, Chorus, and Flanging All of these effects work on basically the same principle: a portion of the audio signal is ''time-shifted" and then mixed back with the direct signal. The amount of time shift is controlled, or "modulated", by an LFO (Low-frequency Oscillator). For phasing effects the shift is very small. The phase difference between the modulated and direct signals causes cancellation at some frequencies and reinforces the signal at others and this causes the shimmering sound we hear. For chorus and flanging the signal is delayed by several milliseconds, with the delay time modulated by an LFO, and recombined with the direct signal. In addition to the phasing effect described above, the delay modulation causes a perceived pitch shift which, when mixed with the direct signal, results in a harmonically rich swirling or swishing sound. The difference between chorus and flanging effects is primarily in the amount of delay time and feedback used--flanging uses longer delay times than chorus, whereas chorus generally uses a more complex delay structure. 5 www.PyleUSA.com Chorus is most often used to thicken the sound of an instrument, while flanging is usually used as an outright "special effect" to produce other worldly sonic swoops. Compression One form of compression known as "limiting" can, when properly used, produce a smooth, unified sound with no excessive peaks or distortion. A common example of the use of compression is to "tame" a vocal that has a wide dynamic range in order to tighten up the mix. With the right amount of compression you'll be able to clearly hear whispered passages while passionate shouts are still well balanced in the mix. Compression can also be valuable on bass guitar. Too much compression can cause feedback, however, so use it sparingly. Most compressors require several critical parameters to be set properly to achieve the desired sound.The MG compressor makes achieving great sound much easier: all you need to do is set a single ''compression" control and all of the pertinent parameters are automatically adjusted for you. 6 www.PyleUSA.com Caution! · To prevent fire or shock hazard, do not expose the unit to rain or moisture. · Do not open the top cover (or the rear section), high voltage exist inside the unit dangerously.
