This 18.5V x2 500mA AC-AC power supply adapter is designed as an aftermarket replacement power cord for selected Behringer XENYX mixer models, including 502, 802, 1002, UB502, UB802, UB1002, Q502USB, Q802USB and Q1002USB. It features AC120V 60Hz input and AC18.5V x2 500mA output with a mini 3-pin connector, making it suitable for compatible home studio, podcast, desktop audio and small recording mixer setups. Please note that this is an AC-AC adapter, not a DC power supply. Before ordering, compare your original adapter label, mixer input requirement and connector shape to confirm compatibility. This adapter is not intended for devices requiring DC output, 4-pin connectors, 5-pin connectors or different voltage ratings. The total cable length is about 10.4 ft, including a 3.9 ft input cord and a 6.5 ft output cord, giving you more flexibility when placing your mixer on a desk, rack or workstation. This is an aftermarket replacement adapter, not an original Behringer product.
