The Fredenstein Bento 6S is a high performance module carrier for Fredenstein Series 600 modules or API-500 compatible plug-in cards. The unit can accept a maximum of 6 modules.

The Bento 6 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 0.15A, 533mA per slot which is about 3 times more than the standard calls for.
 
Low Noise
The Bento 6S power supply is also designed for extremely low noise largely due to state of the art switching regulators that operate above 200 kHz, which is typically higher in frequency than most conventional switching regulators. They also follow “green” guidelines that minimize power consumption to only what is needed.  Other features include the capability to drive very large capacitive loads. Most other switching supplies might oscillate if presented with large capacitors to charge. The Bento 6S ramps up in a controlled manner (typically 0.2 seconds). Also unlike most +/- switching regulators, both the +16V and -16V are regulated separately and provide separate current protection.
 
Auxiliary Audio Inputs and Outputs
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.
