DENSEN B-330
POWER AMPLIFIER
DESCRIPTION
The B-330 is a direct descendent from the top of the line B-350 monoblocks.
The B-350 monoblocks act as the internal reference at Densen.
Basically, the B-330 is a stereo power amp based on the B-350's technology, and uses the distinct monoblock cabinet with its recessed heatsinks as the basis for an extremely affordable reference power amplifier.
The B-330 contains several exciting features. Externally on the backpanel there is a switch to adjust the gain, so it either works perfect with a traditional preamp or with a CD with variable output.
There is also a D-Sub15 connector, allowing for Link connection to other Densen products, and for auto power on/off.
The D-Sub connector can be daisy-chained in multiroom systems.
B-330 is also prepared for the SAXO electronic crossover. This is done by mounting the crossover internally in the B-330 in a socket. The SAXO crossover will fit all passive speakers on the market.

MOON SERIES
330A Stereo Power Amplifier
Significant Design Features:
· 12 Volt Trigger input and output
· A "no overall feedback" design resulting in genuine real-time amplification, a more accurate
musical reproduction with respect to tonality, virtually non-existent intermodulation distortion
and the elimination of common phase errors resulting from feedback
· An oversized power supply
· Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal
loss, yielding an improved power transfer and lower regulation factor. The result is increased
current speed and better dynamics
· Balanced differential circuitry
· Class A output to 5 watts for greater efficiency
· Proprietary MOON Bipolar output transistors with unprecedented gain linearity resulting in
improved bass response and even more accurate sonic reproduction
· A high damping factor yielding superior musical dynamics, improved signal speed and refined
timbre accuracy
· RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
· PCB w/ pure copper tracings & gold plating that yields low impedance characteristics
· Extremely rigid chassis construction to minimize the effects of external vibrations
· Accurate matching of the very finest high quality electronic components in a symmetrical
circuit design
· Designed to be powered up at all times for optimal performance
· Low operating temperature to ensure a longer than normal life expectancy.
