Know before you buy
Yes, the MasterPhono is designed to handle both cartridge types. It features dedicated inputs and selectable gain settings ranging from 40dB to 70dB to ensure optimal performance regardless of your cartridge's output level.
The dual-chassis design physically separates the power supply from the sensitive audio circuits. This isolation significantly reduces electromagnetic interference and noise, resulting in a cleaner, more precise signal path.
The MasterPhono offers ten different impedance settings, including a 'Custom' option, allowing you to fine-tune the load to match your specific cartridge's requirements. You can experiment with these settings to find the balance that provides the most accurate frequency response and tonal character for your system.
No, the MasterPhono is an all-analog device and does not feature an analog-to-digital converter. The USB port is included exclusively for future software updates and feature enhancements to the preamp's internal control systems.
Yes, the unit provides both balanced XLR and single-ended RCA outputs. Using the balanced XLR connections can help reduce noise and interference, especially if you are running longer cable lengths to your amplifier.
The analog meters are designed for monitoring signal levels and assisting with system calibration. They provide a visual reference to ensure your gain staging is set correctly for your specific cartridge and listening environment.
