Description
Passive Stereo Line Isolator
The StageBug SB-6 is a two-channel passive audio isolator designed to accommodate both balanced and unbalanced signals and effectively eliminate noise when used with instruments, consumer electronics, or professional line-level devices.
Features
- Isolator for balanced and unbalanced signals
- Eliminates hum and buzz caused by ground loops
- Exceptionally linear from 20Hz to 20kHz
- Automatically configures for hi-Z or lo-Z signal chains
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.
StageBug SB-6 Applications
- 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 ¼" 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.
Specifications
The SB-6 is a passive isolator that has been designed to work with both balanced and unbalanced signals. As detailed in the graphs below, the SB-6 is exceptionally linear throughout the audio range and exhibits nearly flawless phase shift even in the lower registers. Very low distortion from -40dB to +10dB makes the SB-6 ideally suited for instruments, consumer audio devices and pro-balanced audio signals, while the compact size makes it easy to integrate in just about any situation.
