Welcome to Behringer

Thank you for showing your confidence in us by purchasing the Behringer MICROPHONE PP400, a compact phono preamplifier.

Turntables have low-level signals. However, most audio units can only process line-level signals. Between a turntable and another audio unit (a mixer, an amplifier, or a recording unit), the PP400 acts as an intermediary, as follows:

  1. The PP400 equalizes a turntable signal according to RIAA specifications.
  2. The PP400 amplifies the RIAA equalized signal.
  3. The PP400 outputs a line-level signal.

Please read the safety instructions that appear at the end of this document.

Connectors and Control Elements

This section illustrates and describes each PP400 connector and control element.

V 5.0 A50-00002-78890

  1. 12 V connector: To connect the power supply unit to the PP400, use the 12 V connector. Connecting the power supply unit to the mains automatically switches the PP400 on. To disconnect the unit from the mains, pull out the main cord plug.
  2. ON LED: As soon as the unit is connected to the mains, the ON LED is illuminated.
  3. INPUT (L and R) connectors: To send a turntable signal to the PP400, you need an RCA audio cable (stereo). Use this cable to connect:
    • the left output on the turntable to the L (left) INPUT on the PP400
    • the right output on the turntable to the R (right) INPUT on the PP400
    The PP400 can output a line-level signal via one of the following connectors:
    • RCA ((4) OUTPUT L and R)
    • ¼” TRS ((5) OUTPUT)
    Do not simultaneously use both PP400 OUTPUTs.
  4. OUTPUT (L and R) connectors: To use these RCA connectors, you need an RCA audio cable (stereo). Use this audio cable to connect:
    • the L (left) OUTPUT on the PP400 to the left input on the amplifier, recording unit, or mixer. (On a mixer, use a CD or TAPE input.)
    • the R (right) OUTPUT on the PP400 to the right input on the amplifier, recording unit, or mixer
  5. OUTPUT connector: To use this ¼”, TRS (stereo) connector, you need an audio cable. Use the audio cable to connect the PP400 OUTPUT to an input on the mixer, amplifier, or recording unit. One end of this audio cable must include a ¼”, TRS connector. If the input on the mixer, amplifier, or recording unit is:
    • stereo, the other end of the audio cable must include a ¼”, TRS connector
    • mono, the other end of the audio cable must include 2 TS connectors (one for each mono input)

SERIAL NUMBER: To register your unit, use the serial number that is located on the bottom of the PP400.
