5.2 Output Modes
The D70 PRO SABRE offers versatile output options:
- RCA Single-Ended Output: Standard analog output.
- XLR Balanced Output: Professional balanced analog output.
- Simultaneous Output: You can choose to turn on only the desired output channel (RCA or XLR), or both outputs simultaneously. This is useful for connecting to two different systems or for bi-amping setups.

5.3 Output Level Selection
The D70 PRO SABRE supports different output voltage levels to match various audio equipment:
- XLR: Choose between 4V and 5V output.
- RCA: Choose between 2V and 2.5V output.
This flexibility allows you to adapt to more devices and optimize performance based on your system's requirements.

5.4 Integrated Preamp Function
In addition to the fixed output level DAC mode, the D70 PRO SABRE also features a "preamp" mode. In this mode, you can directly adjust the volume and output to a power amplifier or active speakers, eliminating the need for a separate preamplifier.

5.5 Independent Volume Memory
The D70 PRO SABRE can memorize the output volume for "Single Ended" (RCA), "Balanced" (XLR), and "All" (both) modes independently. The next time you select a specific output mode, the device will automatically revert to the last used volume setting for that mode.
