FAQ — Sphinx v3
Does the Rogue Audio Sphinx v3 include a remote control?
Yes. The Rogue Audio Sphinx v3 Integrated Amplifier includes a solid metal hand-held remote control configured specifically for precision volume adjustment and mute control.
Can I use low-output Moving Coil (MC) cartridges with the built-in phono stage?
Yes. The v3 phono stage features internal DIP switches that allow you to adjust gain (44dB for MM, 60dB for MC) and resistive load settings to perfectly match your specific turntable cartridge.
Does this amplifier have pre-outs for a powered subwoofer?
Yes. The rear panel features both fixed and variable RCA outputs, making it easy to connect active subwoofers or external power amplifiers.
How often do the 12AU7 preamplifier tubes need replacement?
Because the preamplifier tubes are run comfortably within their conservative operating parameters, the included 12AU7 tubes typically offer 3,000 to 5,000 hours of listening enjoyment before needing replacement.
