Routing signal the other way, from a +4 dBu output to a -10 dBV input, can overload the inputs on consumer gear. However, you’ll usually end up with a cleaner signal if you boost the gain within your pro audio gear, as opposed to overdriving the outputs of your consumer gear. This lets you make use of both consumer and professional-level audio equipment.Ĭonnecting a -10 dBV output to a +4 dBu input will always increase the noise floor. If you’re working solely with pro audio gear, most of it likely calls for a +4 dBu line level signal, but some pro audio gear might have a switch that allows you swap inputs between a -10 dBV and +4 dBu mode.
