Pass Laboratories Pass Aleph 60, Руководство пользователя

Страница: 3 / 12

The Aleph 60 uses 12 output devices, the same as in the original Aleph series, and are
matched in the same manner, taken from the same lot codes and matched to about 2% Vgs.
The power supply incorporates much improved line noise filtering in both differential and
common mode, which filters out incoming noise and reduces noise emission by the amplifier.
The Aleph 60 uses 12 computer grade power supply capacitors for 120,000 uF of capacitance
and a 600 watt toroidal power transformer.
One of the biggest differences in the Pass Aleph 60 is the type of chassis and heat sink used.
The Aleph 2 was machined entirely from aluminum extrusions stock. While this resulted in a
unique and very functional appearance, it had several drawbacks. First it was very expensive.
Also, it allowed very limited space for access to input and output terminals on the rear of the
amplifier, and required the on/off power switch to sit in the rear underneath the wiring. It has
been said that ownership of the original Alephs was proof of the owner’s dedication to sound
at the cost of convenience.
The Aleph 60 has a new, more conventional, chassis with heat sinks on the side, a faceplate
with a power switch, and a regular sheet metal type chassis. In addition to being more
convenient, this approach costs less, and we have passed the difference on to the customer.
The final result is that the Aleph 60 performs slightly better than the original Alephs and costs
less.
The Volksamp version of the Aleph 60 is produced under license from Nelson Pass and Pass
Laboratories Inc., and is distributed and serviced by Pass Labs Domestic Sales Inc. and Pass
Labs Foreign Sales Inc.
Thanks you for purchasing it. Enjoy.
