The angle of the mic in relation to the singer is a single most important factor that affects the overall sound. This varies from mic to mic, of course, and also depends on the type of mic. Condenser microphone, for example, will sound brighter and harsher when the capsule is positioned directly on axis with the singer’s mouth. As the capsule is tilted forward, the sound tends to get warmer, darker, and less strident. This is because the sound hits the capsule less directly and the capsule captures more of the singer’s chest resonance. An off axis tilt can also help reduce sibilance and popping caused by plosives.
You can further minimize popping and sibilance by positioning the mic slightly above or below the singer’s mouth. A large diaphragm condenser mic positioned with the capsule pointed directly toward the singer’s mouth will tend to yield the brightest, most focused sound, but it may sound a bit harsh and “spitty.” Usually, a slight downward tilt will make the same mic sound warmer, darker, and smoother, while also reducing susceptibility to plosives. For dynamic mics at least those with cardioid patterns, the opposite is usually true On axis response is warmer and fuller, whereas off axis response tends to sound thinner and less articulate. For that reason, when recording vocals with a cardioid dynamic mic, have the vocalist sing directly into the mic.
Armed with this information, and assuming that you have selected a complementary mic for the singer, you should be able to get the sound you want without resorting to EQ. Indeed, let your mantra be “No EQ whenever possible.” Finally, be aware that the slightest change in the position of the mic or singer can alter the sound drastically. This fact becomes very obvious as soon as you start punching in. Therefore, when tracking vocals especially with a directional mic, ask the singer to make a mental note of his distance and position relative to the mic, and then to maintain that position. For an additional reference, put a strip of tape on the floor just at the edge of the singer’s toes.
