Increase (or decrease) line level output of any analog stereo source by +/-12dB. Great for increasing weak signals or balancing audio output across devices.
Works with any combination of stereo 3.5mm and RCA inputs/outputs. Left and Right channel are independently adjusted using a cross-tip or flat-head screwdriver to rotate sunken controls. This provides greater control and also the option to independently adjust two mono sources. The sunken controls also reduce the likelihood of inadvertent (i.e. customer) adjustments.
Includes UL power supply. RCA and 3.5mm cables not included.
