## mic_sm57_specs.jpg The image is a technical specification sheet for an SM57 microphone. It provides detailed information about its features and performance characteristics. ### Textual Information: - **Model:** SM57 - **Frequency Response:** 40 - 15,000 Hz - **Polar Pattern:** Cardioid (unidirectional) - **Output Impedance at 1 kHz:** 310 Ohms - **Output Level at 1 kHz:** -54.5 dBV/Pa (1.9 mV) - **Construction:** - Die cast metal handle with a dark gray matte finish. - Polycarbonate grille with stainless steel screen. - **Net Weight:** 284 g (10 oz) ### Graphs and Diagrams: 1. **Frequency Response Graph:** This graph shows the microphone's sensitivity across different frequencies, ranging from 40 Hz to 15 kHz. The x-axis represents frequency in Hertz, while the y-axis indicates the output level in decibels relative to a reference pressure (dBV/Pa). There is a clear peak around 2 kHz and a gradual decline at higher frequencies. 2. **Polar Pattern Diagram:** This diagram illustrates how the microphone's sensitivity varies with directionality. The x- and y-axes represent angles in degrees, ranging from -90 to +90 degrees (left to right). The lines indicate different frequency ranges: 1 kHz, 1000 Hz, 2 kHz, 4 kHz, 8 kHz, and 20 kHz. The cardioid pattern is evident as the sensitivity drops off significantly outside a narrow angle range in front of the microphone. 3. **Output Impedance Diagram:** This graph shows how the output impedance changes with frequency. It's represented by two lines: one for the solid line (1 kHz) and another for the dotted line (10 kHz). The x-axis is labeled "Frequency," and the y-axis represents impedance in Ohms.
