• Single Ended output = 11.3 dB
• Balanced Output = 5.5 dB
• Single Ended Output = 3.5 dB
• Balanced Output = -2.3 dB
• Single Ended Output = -9 dB
• Balanced Output = -14.8 dB
All outputs are the same for single ended and balanced:
• 32 ohm = 205 mW
• 50 ohm = 320 mW
• 300 ohm = 68 mW
• 600 ohm = 34 mW

Theorem 720 DAC® Product Manual
We’ve uploaded the latest PC driver version 1.67 to our site.
Please uninstall the older driver (either ver 1.60 or 1.61) and install the new version 1.67 to receive support for Windows 8. Both the old drivers and this new one support 24/192 files.
If you have both an AlgoRhythm Solo -dB and Theorem 720 DAC, you may need to install the driver for each device, but the second install is only about 1 second. Be patient with the first install.
