Analog DAC MSB Pro I2S Input Module

** This module is a proprietary format only intended for MSB Transports. For the standard Pro I2S input that is intended for third party servers/transports please see Universal I2S module**

This is our earlier proprietary interface. We offer this input for legacy products. This interface uses a completely proprietary electrical interface and has no resemblance to common I2S on the cabling. It provides clock feedback and a medium level of isolation between source and DAC.

Maximize the performance of your classic MSB digital front end with our genuine Pro I2S Input Module. Engineered specifically to interface with the flagship transports of their era—including the Signature Data CD and the Universal Media Transport (UMT) IV—this module delivers bit-perfect, ultra-low-jitter audio data straight to your DAC.

While the our legacy DACs have been retired, we have a limited supply of these original factory modules remaining in our inventory. Whether you are replacing a lost module or upgrading your DAC to finally experience the proprietary I2S connection, this is a rare opportunity to complete your legacy MSB stack.

Key Features:

• Genuine MSB OEM Part: Manufactured in-house by MSB Technology to ensure pristine audio quality and perfect integration with your legacy equipment.

• Total Source Isolation: Keeps the noisy electrical environment of the disc drive or media transport strictly separated from the sensitive digital-to-analog conversion circuitry.

• Seamless Integration: Features our classic plug-and-play modular design. The module slides perfectly into the isolated input bays on the rear of your compatible legacy MSB DAC.

Important Note: This module utilizes MSB’s proprietary Pro I2S connection, designed exclusively to mate with MSB transports like the Signature Data CD and UMT IV. It is not compatible with third-party I2S-over-HDMI or RJ45 sources. As this is legacy factory stock, inventory is strictly limited and available only while supplies last.

Installation: Ensure your DAC is powered off and completely unplugged before swapping modules. Remove the blanking plate from an open input bay. Align the Pro I2S module with the internal guide rails, press it firmly into the chassis until it is fully seated. Connect to your transport using the dedicated MSB Pro I2S cable.
