Behringer MicroPHONO PP400 User Guide

BEHRINGER MICROPHONO PP400
WELCOME TO BEHRINGER
Thank you for showing your confidence in us by purchasing the
BEHRINGER MICROPHONO 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.
Fig. 1: PP400 connectors and control elements
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.
ON LED:
As soon as the unit is connected to the mains, the ON LED is
illuminated.
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:
V the left output on the turntable to the L (left) INPUT on the
PP400
V 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:
V RCA ( OUTPUT L and R)
V ¼" TRS ( OUTPUT)
 Do not simultaneously use both PP400 OUTPUTs.
OUTPUT (L and R) connectors:
To use these RCA connectors, you need an RCA audio cable
(stereo). Use this audio cable to connect:
V 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.)
V the R (right) OUTPUT on the PP400 to the right input on
the amplifier, recording unit, or mixer
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:
V stereo, the other end of the audio cable must include a
¼", TRS connector
V 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.
