The ART AV Direct Audio/Video Direct Boxis the perfect solution you need for connecting multimedia sources such as MP3 players laptops DVD players and HiFi equipment to a single XLR microphone level input. It eliminates the need for an AV room with a handy level control knob that is ideal for setting the volume of the component at the source. This DI box also features a switchable 4.8 kHz high-cut filter and ground lift to eliminate all the annoying unwanted noise that is commonplace in environments where longer cabling and multiple power sources are used. The AV Direct is versatile and ready for whatever source you need to connect with input connections including a stereo RCA 1/8-inch and 1/4-inch TRS line inputs as well as a 1/4-inch and bare wire pressure clip speaker level inputs. Transformer isolated from XLR output means that amplified speaker levels can be tapped off and sent to a regular microphone level input.
