The SB-6 is a passive audio isolator designed to be inserted into the signal chain to block hum and buzz caused by ground loops. The SB-6 accepts both unbalanced or balanced signals and is equally suitable for electric guitar, stereo keyboard, consumer electronics and professional line-level devices. The two channels operate independently for dual mono or stereo and since the circuit is passive, no power is required. Whether you are connecting an unbalanced or balanced signal, the SB-6 will automatically convert the signal depending on the type of cable and connector you are using. You simply plug in and play.
Problem solver for stereo systems
The SB-6 helps remove noise from two channel audio systems, stereo guitar racks, and pedalboards. Two on-board isolation transformers provide a flat frequency response from 20Hz to 20kHz, while removing hum and buzz from ground loops. Dual ground lift switches help further reduce noise, and a -15dB pad allows you to handle high volume outputs without distortion. When using the SB-6 before a set of powered speakers or guitar amplifiers, a polarity reverse switch corrects frequency cancellation and ensures both speakers play back in phase with one another. The SB-6 is completely passive with no need for power, so it's easy to insert into any system to remove noise quickly.
Using the SB-6 in a stereo setup
Isolate the output from a DJ Mixer to a power amp using the SB-6 to eliminate hum and buzz caused by ground loops. Either 1/4" mono or TRS connectors may be used.
Using the SB-6 in a pro setup
When running multiple speakers, you can often encounter noise due to imperfect power systems and DC offsets. Use the SB-6 to isolate distant loudspeakers to solve the problem.
Using the SB-6 in a guitar rig
Eliminate noise in your guitar setup by isolating the guitar amp from other electronic devices. This SB-6 works great between your pedalboard or with your wireless system.
