Operating Manual
Fredenstein F609 Tube Microphone Preamplifier
The F609 is a professional tube microphone preamplifier, using two double-triodes, one ECC802S
and one ECC803S, in a single 500 series rack module. It provides an +160V power-supply to avoid
starving the tubes. The F609 uses high quality American made input and output transformers.
Additional features are: 20db Pad, polarity control, phantom power, a two stage low-cut filter, and a
standby mode to preserve the tubes if not in use. The sound is very smooth with a big, but well
defined, low-end. The output level control allows to change the characteristic of the amp and to run
the first stages all the way up to distortion.
As all Fredenstein products, the F609 is designed by a German-American team and manufactured in
Taiwan.

Fredenstein F609 Tube Microphone Preamplifier
Installation:
Please power down your rack or box first before inserting the F609 . The power requirements
are maximum +/-16V, +/-250mA. In case you don't use a Fredenstein Bento, please make sure
your box or rack can support the current. Please consult your third party documentation in
case of any doubt.
Gain Control:
Microphone Preamplifier Gain Control, minimum +34dB, maximum +70dB.
Output Control:
Range -20dB to 0db. The 0db position is the normal linear setting.
PAD – Input Attenuator
Atcivating PAD attenuates the microphone signal by 20dB. PAD does not change the DI level.
POL – Polarity Control:
Setting the signal polarity, when turned on, the signal is inverted.
Low Cut – High Pass Filter:
Two stage low-cut filter, 50Hz or 100Hz
P48 Phantom Power:
Most FET condenser microphones as well as some other microphones with built-in amplifiers
require +48V Phantom Power. Setting the P48 switch to the right 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.
ON – Standby Switch:
Turns the F609 on (switch in upper position, green LED lit) or activates standby mode (switch in
lower position, yellow LED lit). In standby mode, the high voltage supply, the tube heaters and the
VU meter back-light are turned off. Please allow 30 seconds for the amp to be fully functional after
turning it on.
DI – Direct Input:
The most common use for the DI input is to connect instruments like guitars directly to the F609.
The input impedance is greater than 500 KOhms to insure compatibility with most instrument
pickups. After inserting an unbalanced (TS, Tip-Sleeve) plug, the balanced microphone input
through the box or rack is automatically disabled.
Please note:
As a pure analog product, the F609 does not support digital read-out on Bento D displays.
