2 Channel Variable Passive Studio Attenuator Pad – Balanced Line to Mic Level Control Box

Professional passive 2-channel variable studio attenuator pad designed for precise level matching in professional recording environments. This high-end variable line attenuator safely reduces hot +4 dBu studio line-level signals down to mic-level or line-level outputs, preventing clipping in audio interfaces and converters.

Perfect for studio recording, gain staging, analog saturation workflows, and outboard gear integration, allowing you to drive your mic preamps harder while maintaining a clean, controlled signal path.

What is a Variable Studio Attenuator?

A variable studio attenuator (also known as a line level pad or signal attenuator box) allows adjustable reduction of audio signal level between devices. Unlike fixed pads, a variable attenuator pad gives you flexible control over gain staging and saturation levels in your studio chain.

This 2-channel passive attenuator is designed for both balanced TRS and unbalanced audio systems, making it ideal for professional and hybrid studio setups.

Drive Your Gear Harder – Without Clipping Your Converters

The 2 Channel Variable Line/Mic Level Audio Attenuator Pad is a premium dual-stereo balanced studio tool. With 2-in and 2-out 1/4″ TRS connections, it functions as both a load box and a variable line-to-mic level pad.

Using high-grade Vishay precision metal foil resistors, this passive attenuator ensures a fully transparent signal path with no frequency loss or coloration, even when switching between attenuation levels.
