Audio Transformer Neutrik NTE10/2 50000 Ohm 1.2V

Neutrik NTE10/2 50000 Ohm 1.2V is an audio transformer designed for signal coupling, impedance matching and galvanic isolation in professional audio systems. With a specified primary impedance of 50,000 ohms and a 1.2 V rating, this compact transformer provides electrical separation between stages or devices to reduce hum and ground-loop interference while maintaining signal integrity. It is intended for installations in mixers, preamplifiers, audio interfaces and similar equipment where high input impedance and reliable isolation are required.

Advantages

The transformer offers galvanic isolation to prevent ground loops and associated noise without altering the waveform characteristics of the audio signal. Its high specified impedance supports sensitive input stages and helps maintain correct impedance relationships between connected devices. The design supports low-level signal transfer with minimal distortion and consistent performance across the audio band. Durable construction ensures stable operation in professional and installation environments.

Suitable for

• Connecting line-level outputs to high-impedance inputs
• Isolating audio equipment to eliminate hum and ground-loop noise
• Use in mixers, preamps and audio interfaces for signal coupling
• Installations requiring impedance matching between stages

Key specifications

• Primary impedance: 50,000 ohm
• Rated voltage: 1.2 V
• Function: audio signal coupling and galvanic isolation
• Application range: line-level and low-level audio signals
• Typical use: professional audio equipment and installations

How to use

Install the transformer according to the equipment manufacturer's guidelines and standard audio wiring practice. Connect the input (primary) to the source device output and the output (secondary) to the receiving device input, observing correct polarity where applicable. Ensure secure mechanical mounting and appropriate shielding or placement to minimise electromagnetic interference. Verify levels after installation and adjust gain staging on connected devices to accommodate the transformer's impedance and rated voltage.

Recommendations

For best results, use the transformer in combination with proper gain staging: set source and destination device levels so the transformer's 1.2 V rating is not exceeded, and confirm that the high input impedance suits the downstream circuitry. Maintain cable shielding and grounding practices for the overall system to complement the transformer's isolation properties.
