BHI GroundBreaker GB8S 8 Ohm stereo audio isolator

Tired of hum, interference, or RF ingress in the audio signal of your radio installation? The BHI GroundBreaker GB8S i is a compact 8 Ohm stereo audio isolator that helps prevent ground loops and RF interference in the audio path. The GroundBreaker provides galvanic isolation between your radio and connected audio equipment, so unwanted ground currents can no longer flow directly from one device to another.

This GB8S is the stereo version within the BHI GroundBreaker series. Unlike the GB8M mono version, the GB8S features two separate audio channels. This makes it particularly suitable for equipment with a 3.5 mm stereo connection and installations where the left and right channels must remain separate.

Less hum and RF interference in your audio

When a transceiver, scanner, DSP unit, computer, or other audio equipment is connected together, differences in grounding can cause a ground loop. The result can be audible hum, distortion, or RF bleed-through, for example during transmission.

The BHI GroundBreaker offers a simple solution to this. By isolating the grounds of the connected devices from each other, the direct electrical connection via the audio path is broken. You do not need to make complicated modifications to your equipment: the GB8S is simply placed between the audio output of the radio and the connected device.

What do you use the BHI GB8S for?

The BHI GroundBreaker GB8S 8 Ohm stereo is suitable for use, among other things, between a transceiver or scanner and a stereo DSP unit, active speaker, or other suitable audio equipment. The GroundBreaker can also help prevent a ground loop via connected equipment in a connection between radio equipment and a PC sound card.

With stereo DSP equipment or equalizers, the GB8S has the advantage that both audio channels remain separate. This makes it suitable, for example, for setups where different audio signals are processed via the left and right channels.

The main features:

• 8 Ohm stereo version with two separate audio channels
• Helps reduce RF interference, ground loops, hum, and unwanted audio bleed-through
• Galvanic isolation between radio and connected audio equipment
• 3.5 mm stereo connections for easy integration into the audio path
• Loadable up to a maximum of 500 mW per channel

Simply place between your equipment

Installing the GroundBreaker is simple. Place the GB8S in the audio path between the external speaker or headphone output of your transceiver or scanner and the input of, for example, a suitable DSP unit or active speaker. In many situations, no additional cables are needed, depending on the connections of the equipment used.

The galvanic isolation can also be important when audio devices use different grounds. Instead of connecting them directly electrically, the GroundBreaker keeps both sides of the audio path separate.

Pay attention to the maximum power

The BHI GB8S is loadable up to a maximum of 500 mW per channel. Therefore, do not use it as a connection where the full speaker power of a transceiver is sent to a passive speaker. The GB8S is intended for suitable audio signals to, for example, a DSP unit, active/amplified speaker, or headphones, within the specified load capacity.

Do you want to tackle hum, ground loops, or RF interference in a stereo audio path without complicated modifications to your installation? Then the BHI GroundBreaker GB8S 8 Ohm stereo is a practical plug-and-play solution. Order the BHI GB8S from Deltron.nl and ensure a reliably isolated audio connection in your radio installation.
