STUDIO BOARD & MIX When you mix a song be in considerate that you want to bring the listener on journey throughout the mix.  Focus on each instrument throughout the track.  To control readers on the mixing board Control surface - set up Set input and output  SENNHEISER MD 421 II    - Cost $379.95 made in Germany Overall Cardioid Polar Pattern Dynamic Microphone - D oes not require 48V Phantom Power to operate however the presence of 48V Phantom Power should not adversely affect the operation of the MD 421-II. Frequency Response - 30Hz to 17,000Hz ( live engineers, use it as default for saxophones and trumpets , and it is paired well with the SM 57 for Guitar Cabs ) Effective feedback rejection Clear sound reproduction 5 Position Bass Control - S( cuts the low end by approximately 6dB below 500 Hz) to M   What is the maximum Sound Pressure Level (SPL) for the MD 421-II?   ...

Sound Waves, Acoustic Treatment and Bass Placement

Sound Waves 1.  What is a  sound wave Sound is produced when something vibrates .  Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively. The shaded bar above it represents the varying pressure of the wave. Lighter areas are low pressure (rarefactions) and darker areas are high pressure (compressions). One  wavelength  of the wave is highlighted in red. This pattern repeats indefinitely. The wavelength of voice is about one meter long. The wavelength and the speed of the wave determine the pitch, or frequency of the sound. Wavelength, frequency, and speed are related by the equation speed = frequency * wavelength. Since  sound travels at 343 meters per second  at standard temperature and pressure (STP), speed is a constant. Thus, frequency is determined by speed / wavelength. The longer the wavelength, the...
