The B-350 is Densen's top of the line power amp. The new B-350 contains
a completely new output stage, built using Densen’s unique "DMCD"
technology (patent pending). This makes the B-350 extremely fast and
precise, while retaining unlimited control of the speakers. The bandwidth
has also been improved and the B-350 goes straight to 400.000Hz, resulting
in improved slew-rate and an extremely fast and detailed sound.
The B-350 is built using surface mounting teqniques, and the components
are mounted to a precision of 0.02mm using silver solder. All solderings
are carried out in an artificial nitrogen atmosphere to avoid oxidation
of the solderings. The power supply is massive and consists of a
750VA transformer and has a storage capacity of 100.000uF with 4
seperate rectifiers, 2 of which are capable of 3.000VA. Unusually
for an amplifier, not all the capacitors are mounted in a capacitor
bank, as some are located next to the output stage for faster power
delivery. All resistors are laser-trimmed metalfilm from Vishay
with a precision of 0.1%. The B-350 delivers 125W at 8 ohm, and
250W in 4 ohm.
No local or global feedback is one of the key issues with the B-350.
This technology is further improved with Densens new patent pending
DMCD (Dense Mass Current Distribution) circuit. By using the DMCD
circuit, the current is at all times present at the output terminal.
This results in an extremely low output impedance and a truely non-feedback
amplifier.
The printed circuit board is made of teflon and is doublesided,
allowing the signal to be placed on one side and groundplane on
the other, thereby optimising interference free signal transfer.
The B-350 contains several exciting features. On the backpanel
there is a switch to adjust the gain, so that the B-350 works perfectly
with a traditional preamp, as well as a CD-player with variable
output.
There is also a D-Sub15 connector, allowing for DenLink connection
to other Densen products, such as auto power on/off. |
