Fredenstein Artistic Microphone Preamplifier SE
The Artistic microphone preamplifier is the first member of the Fredenstein Value Line of 500
series compatible products. The Artistic Pre SE features top of the line performance at a very
affordable price. ey component to achieve this performance level is our fully discrete gain stage
and DI input. As all Fredenstein products, it is not a copy of an older design, but a completely new
circuitry manufactured in SMT technology.
A 2M Ohms high impedance direct input is located on the front-panel, it accepts balanced and
unbalanced signals, the rear microphone input is automatically disconnected when a plug is inserted
in the DI connector.
The features include a maximum gain of 65 dB, a 20 dB Pad, switchable polarity, low-cut filter,
and Phantom-Power support. Our new eight LED Peak-Meter with a 50 dB range gives the user a
precise reading of the operating conditions.
As all Fredenstein products, the Artistic Pre is designed by a German-American team and
manufactured in Taiwan.
Installation:
Please power down your rack or box first before inserting the Artistic Mic-Pre SE. Please scecure
the SE firmly to the rack with two M3x7 or M3x10 flat head screws. The power requirements are
not very demanding at a maximum of +/-50mA and the Artistic Mic-Pre SE should work in weaker
racks as well.

Gain Control:
Microphone Preamplifier Gain Control, minimum +20 dB, maximum +65 dB
POL – Polarity Control:
Pushing the POL switch selects the polarity, when lit (blue), the output polarity is reversed.
Otherwise the true, non-reversed, polarity is selected (normal operation).
PAD – Input Attenuator:
Setting the PAD switch (orange light) activates a 20dB attenuator at the input allowing line level
signals to pass through the preamplifier (note: Pad is not affecting the DI input)
Lo -cut – High Pass Filter:
When lit (green), frequencies under 120Hz will be softly attenuated.
P48 Phantom Po er:
Most FET condenser microphones as well as some other microphones with built-in amplifiers
require +48V Phantom Power. Setting the P48 switch (red light) enables +48V through the balanced
microphone line. Please check your microphone documentation if you are not 100% sure. Enabling
P48 on microphones not designed for P48 might cause severe damage to the microphone. The DI
input is not supplied with Phantom Power.
DI – Direct Input:
The most common use for the DI input is to connect instruments like guitars directly to the Artistic
Pre. The input impedance is greater than 100 Ohms to insure compatibility with most instrument
pickups. After inserting a balanced (Tip-Ring-Sleeve) or an unbalanced (Tip-Sleeve) plug, the
balanced microphone input through the box or rack is automatically disabled.
