Frequently Asked Questions

AI
RF attenuators manage high-frequency electromagnetic signals and are rated by frequency range and power handling (Watts). Audio attenuators control sound volume levels and are rated by impedance (Ohms) and connector type (e.g., 3.5mm, RCA).
Fixed attenuators provide a single, precise reduction value and are ideal for permanent installations. Variable attenuators allow you to adjust the signal strength on the fly, making them better for testing, debugging, or dynamic mixing environments.
Match the connector to your existing equipment. Common RF types include SMA, N-Type, and BNC. Audio connections typically use 3.5mm TRS, RCA, or XLR. Ensure the gender (male/female) matches your cable or device port.
