ART CleanBOX Pro 2-Channel Line Level Converter
ART CleanBOX Pro 2-Channel Level Converter
This unique device can be used in two ways. It can convert a line level balanced signal into a consumer level unbalanced signal. It can also be used to convert an unbalanced consumer level signal into a balanced line signal. This is used to gain optimal signal strength when transferring a signal between devices with different output and input signal types.
Consumer vs. Line
A consumer level signal, also known as -10dBV, is commonly used for household audio appliances, such as a CD player, or DVD player, PC or Laptop. A line level signal, also known as +4dBV, is used for most pro audio equipment, such as keyboards, mixing consoles, and DJ mixers.
In order to maintain maximum signal integrity it is important to connect the right type of signal into a device. Inputs are usually designed to accept one signal type only, and only this signal type will result maximum signal/noise ratio.
For example: This device would be used to plug a CD Player (-10dBV) into a Pro Audio Amplifier or Powered Speaker (+4dBV) to gain maximum signal transference.
Packed Full of Goodies
As well as converting signal types, this device features a preamp for each output to give it that extra bit of juice. It also has a 1/8" stereo input/output enabling conversion to/from an iPod/laptop/PC signal. The unique power socket allows the device to be powered by a 7.5-12V AC or DCcurrent.
