Balanced / Unbalanced Line Level Converter
Balanced / Unbalanced Line Level Converter
The MCM Custom Audio Model 555-8485 Line Level Converter is an essential interface in sound systems that utilize a combination of professional audio gear, with consumer home theater equipment, PCs, laptops and portable MP3 players. The 555-8454 Line Level Converter incorporates four independent low noise audio amplifier circuits, to provide two stereo audio channels. Channel 1 Accepts L/R RCA type unbalanced consumer line level inputs, electronically balances the signal, amplifies it to pro-sound line level, and supplies it to two male XLR output connections. Channel 2 Accepts L/R XLR balanced inputs, electronically converts them to two unbalanced channels, and provides attenuated signal to L/R RCA outputs. Both channel 1 and 2 include level controls for fine adjustment of each pair. Note: The advantage of higher gain, balanced audio signals with pro-sound gear is its immunity to induced noise and interference. Since the signal is balanced on two lines, any interference that is introduced on the line is cancelled out at the destination. Additionally, the higher signal level insures better signal-to-noise ratio on the line. Therefore, if this device is to be used on consumer equipment that is a great distance from the amplifier or mixer input, it should be located as close to the source as possible. That will allow the distance of signal to be sent at the higher, balanced level.
