  • What is the input voltage of the P7?

    The P7 operates at DC 12V/≥2A. Using over voltage can cause damage, while insufficient current may affect normal operation.

  • Can I connect a turntable directly to the P7?

    Before connecting, please check if your turntable has a built-in phono preamp. If so, use the RCA input to avoid unwanted noise.

  • Can the RCA and XLR outputs be used at the same time?

    Yes, they output at the same time, with their volume and tone controlled simultaneously.

  • Is the high-pass filter active in RCA input mode?

    No. The high-pass filter is only available in phono input mode.

  • Can I swap op-amps and replace the tubes in the P7?

    Yes, P7 uses 3 NE5532 op-amps, replaceable with 2604, 2134, MUSES02, etc. Ensure correct installation before powering on due to high voltage. Supports PSVANE 12AX7-S, Shuguang 12AX7B, 7025, or 12AX7 tubes. Replace tubes only when powered off.
