Stereo line isolator rack 19" Omnitronic LH-082 2-channel

Omnitronic LH-082 is a 2-channel stereo line isolator for 19" rack mounting that provides galvanic isolation between audio sources and destinations. Designed for professional audio environments, the unit reduces hum, ground loops and interference, helping to maintain clean signal paths in studio and live sound setups. The compact rack format and straightforward signal routing make it compatible with mixers, amplifiers and outboard processors where reliable isolation is required.

Advantages

The LH-082 offers two fully isolated stereo channels in a single 19" rack unit, ensuring separation of left and right signals to prevent cross-talk and interference. By using passive galvanic isolation, the device lowers the risk of ground loop hum without changing signal characteristics or requiring external power. The robust rack housing and standard connectors deliver consistent, long-term operation in studio racks and touring systems.

Suitable for

• Isolation between mixers and amplifiers in live sound rigs
• Connecting outboard processors to mixing consoles without introducing ground loops
• Studio patchbays and rack chains where clean line-level signals are required
• Broadcast installations where interference reduction and signal integrity are important

Key specifications

• Form factor: 19" rackmount, 1U height
• Channels: 2 stereo channels (left/right per channel)
• Isolation type: galvanic isolation (passive transformers/isolation circuits)
• Input/output: balanced line-level connectivity compatible with mixers and processors
• Frequency response: suitable for full audio bandwidth (audio range)
• Construction: metal rack housing for professional use

How to use

Install the LH-082 into a standard 19" rack and secure it using the front-mounting holes. Connect the line-level outputs of the source device (for example a mixer or processor) to the inputs of the corresponding LH-082 channel, and then connect the channel outputs to the destination device such as an amplifier or another console input. Ensure balanced wiring where supported; passive galvanic isolation will then prevent ground loop currents and reduce hum. No external power is required for normal operation.

Usage recommendations

Place the isolator close to either the source or destination in the signal chain to minimize cable runs. When integrating into complex racks, label inputs and outputs to maintain clear signal routing and periodically check connectors for secure contacts to ensure consistent isolation performance.
