Detailed Description
Detailed Description
We designed the LGB-4 to solve an increasingly frustrating problem - how to get the same output level from multiple devices, especially when some devices have inherently low outputs (such as smart phones, tablets, portable audio players and even some media streamers and computer sound cards). The LGB-4 is a perfect partner for whole-house audio systems that include multiple audio inputs. The LGB-4 significantly reduces the volume level changes that otherwise occur when switching between sources.
Each input/output combination on the LGB-4 actually has an adjustment range of -12dB to 0 to +12dB. So you can also attenuate a stronger than normal signal.
