If the SB-7 does not need power, how does it work?
The SB-7 is completely passive. It takes the amplified signal from the headphone amplifier and manages it using a mix of preset and variable resistive components. These do not introduce any form of coloration or distortion.
Why did you not include an LED indicator?
Because adding an LED would require adding a power supply which would increase the cost. Large studios will need many of these, so we decided to make it as small and affordable as possible.
How do I reverse the mute so that it affects the right ear?
You could rewire your headphones… or simply turn them around. For artists that use only one active phone, the stereo fit is not important, so this is really not a problem.
How does the mono switch work?
It combines the left and right channels using a passive summing mixer.
Can I use both the ¼” and the 3.5mm outputs at the same time?
Yes. Although there is no way to differentiate the level going to each one.
Can I use more than one SB-7 in series to split a headphone feed?
Yes, but this requires some compromise. To do this, connect the first SB-7 as described on the using page, then send the output to the second SB-7 using either the ¼” or 3.5mm output. Note that the first SB-7 will control the level and decisions such as muting one side or collapsing the stereo signal to mono.
Can I use the output from my PC to drive the SB-7 and a set of full sized headphones?
Yes. Simply set the level to full and you will not notice any drop in level.
For practicing, can I plug a guitar into the SB-7 and then a set of headphones?
No. As the SB-7 is completely passive, it does not have a headphone amplifier built in. Pickup for great sounding results!
