Fredenstein Bento 6D Rev. A Module Carrier
The Fredenstein Bento 6D is a high performance portable module carrier for Fredenstein Series 600
modules or API-500 compatible plug-in cards The unit accepts a maximum of 6 modules
The Bento 6D features several important upgrades compared with third party products:
Universal power supply: Mains voltages range from 90V AC to 240V AC, 50 to 60 Hz
Increased output currents: +-16V DC 1 6A and +48V DC 0 1A (530mA per slot)
LCD Display: Monitoring the power-supply status and, if certain Fredenstein modules are used, like
F600A, F601A, F603A/B, F604, and the F607, all operating parameters oft theses modules are
displayed in real time as well For example, if you are operating a F603A/B EQ, all selected
frequency ranges and the exact gain of each band are displayed This feature simplifies working
with the F600 modules substantially Only Fredenstein offers such functionality:
Auxiliary Audio Inputs and Outputs
Built-in compatibility switches for non-conforming modules
Built-in Audio Routing: Modules can be daisy-chained by simply flipping switches on the back-
panel
Compressor buss linking: Compressor modules can be linked by engaging switches on the back-
panel as well
Multi-Layer Backplane: Increased signal integrity and lower noise floor
Ground-lift switch: In case of ground loops, the audio ground and the protective ground can be
disconnected Please use only if absolutely necessary
Installation:
Electrical Safet Warnings:
Do not open the enclosure, hazardous voltages are present inside!
There are no user serviceable parts inside.
Alwa s disconnect the mains cord before installing or removing modules!
If ou need to replace the mains fuse, make sure the replacement has the same
rating (2AT 250V, slow blow).
Please disconnect the mains from your Bento 6D before installing or removing modules Make sure
each installed module is well seated in the receiving connector and the module is secured by
fastening the two mounting screws (size: M3)

If certain non-Fredenstein modules are used, which bridge several pins on the connector and
connected the contacts on the top and button side, the double switches, located directly besides the
slot connectors, can both be turned off (lower position) to avoid interference between the module
and the digital interconnect For Fredenstein modules, both need to be in the ON (upper) position
Operation:
After installation of the modules connect the mains cord to the Bento 6D IEC socket located on the
back-panel and than connect the mains cable to a grounded outlet Now turn the Bento 6 on by
operating the I/O switch (also part of the IEC socket on the back) After performing a brief self-test,
the Bento 6D will display all three supply voltages
In case you want, for example, route the audio signal from a mic-pre in slot 1 to a EQ in slot 2 and
then to a compressor in slot 3, turn the switches located in the lower part of the back-panel between
the slot 1 and 2 and slot 2 and 3 in the link position (Please be aware that this disables the slot 2
and the slot 3 input XLR connectors) Slot 1 input will be the microphone input and the slot 3
output will be the audio output of the complete chain
In case you are using multiple compressors which make use of the compressor link buss (Pin 6),
you can link two adjacent slots by putting the buss switch in the I position You have the flexibility
to have 5 buss segments for operating five Stereo compressor setups by engaging buss switches
between the slots 1 & 2, 3 & 4, and 5 & 6 or any other combination including a global buss if you
engage all buss switches (5 1 configuration) If you are using different types of compressors, you
must keep them on separate segments of the buss
In case of severe ground loops you might engage the ground-lift to alleviate such problems But it is
always recommended to resolve the grounding problems at their source and keep the ground-lift
switch disengaged (OFF position)
The AUX Input and AUX Output connectors can only be used with modules especially designed for
Bento module carriers, like the Fredenstein F604, F605, F606, and F607
