Proel DB1P

D.I. Proel DB1P passive speaker

• the innovative mechanical design of the D.I. Box involves the use of an aluminum and rubber case for the corners, for maximum protection, even in the harshest conditions
• when the rubber corners are removed, you can see two markings that allow the connection of two D.I. units. Box, which can then be mounted in a standard 19-inch rack-type unit.
• this unique feature is extremely convenient for engineers who need a large number of D.I. units. Box within the same application
• D.I. units Box transforms audio signals from unbalanced to balanced, reducing the possibility of electrical disturbances on the line, especially in the case of connections that require very long cables
• Proel's DB series includes three different models of D.I. units. Box, high performance: active, with one channel (DB1A), passive with one channel (DB1P) and active with two channels (DB2A)
• by their design, the units in the DB range from Proel ensure a clean transmission of the signal, without interference or impedance compatibility problems, from the musical instrument to the mixing equipment, even in the case of very long cables
• on the front panels are mounted a wide range of connectors (XLR, JACK and RCA, depending on the model), allowing an easy connection between a variety of sources (keyboards, guitar, bass, music players of any type)
