Aleph 1.2 Power Amplifier
Picture of the Aleph 1.2 Aleph 1.2 Owner's Manual

The Aleph 1.2 is the largest amplifier from Pass Laboratories and expands upon
the vision of pure high power, idling at 500 watts and delivering 200 watts in
single-ended Class A.
Single-ended Class operation is often referred to as the "king of Class A"
because it has the smoothest transfer curve and operates at the lowest
efficiency of the family of Class A topologies. Properly designed, a single-
ended amplifier exhibits second and even order harmonic structure, similar to
the transfer characteristic of air, where the phase of the signal and
harmonics reflects the subtle difference between acoustic compression and
rarefaction. The price paid for this performance is in high idle current and
dissipation, generally three to five times the output rating.

The Aleph 1.2 conforms to the Pass philosophy of having absolutely minimal
parts in series with the signal path. The input signal travels through a
resistor to the input Mosfet transistor, and from there through another
resistor to the parallel output Mosfets, and from there through a power
resistor to the loudspeaker. There are only two sets of gain devices and three
resistors between the input and output. This minimalist topology is supported
outside of the signal path by regulated current sources which separately bias
the input and output stages.

The Aleph 1.2 is unlike the original Aleph 1 in two important ways. First, it
has only two gain stages instead of the original three. With one less gain
stage, there is less information lost within gain devices and in feedback.
There is improved intimacy between the input and output, resulting in greater
immediacy, detail, warmth, and depth.

The amplifier also does not have the auxiliary pull circuitry which allowed
the Aleph 1 to deliver very high currents into low impedance loads. This is a
purer approach, however it does not allow for greater power below 4 ohms. The
amplifier will drive and is stable into any load impedance or reactance
including a direct short, and delivers clean audio into very tough loads.

The current source which biases the output stage is a new design which
maximizes the performance of the output stage into reactive loads. It helps to
optimize the load-line of the single-ended output devices, lowering
distortion. The design of this current source is protected by US patent
application.

The Aleph 1.2 uses power Mosfets for both gain stages. These Mosfets were
chosen because they have the most ideal transfer curve for an single-ended
Class A design. Mosfets also allow high current operation with low circuit
complexity, delivering high performance in a minimalist topology.

The input P channel and output N channel Mosfets are carefully selected from
the same manufacturing lot codes and matched to a tolerance of 2%. Precision
metal film resistors are used throughout.

The Aleph 1.2 has been designed for maximum reliability and years of trouble
free operation. The input gain devices are pulse rated 8 amps and are followed
by output devices with pulse ratings of 50 amps each. The amplifier employs
3.6 kilowatts of power Mosfet output devices and massive heat sinking rated
at .05 degree per watt. During active operation the amplifier consumes 500
watts, so that each output device is operated at 14% of its rated power. The
Aleph 1.2 is protected from overheating by a 75 degree C. thermal switch, and
from internal failure by a slow-blow fuse.

The amplifier is powered by a toroidal transformer rated at 10 times the
amplifier's output rating which charges 100,000 uF of supply capacitance to
500 Joules. This unregulated supply feeds the output transistors with a full
power ripple of about 1/2 volt.

The amplifier is equipped with a balanced input featuring a common mode input
noise rejection of -60 dB, accomplished through a passive network tied
directly into the input stage of the amplifier, not with additional active
input circuitry. Unbalanced input is accommodated through RCA connectors.

The ultra-high bias current, the transconductance character of the Mosfets,
and the simple design topology all combine to deliver an amplifier having high
power and strong "bench" performance while still delivering the emotionally
involving warmth and depth associated with the finest tube amplifiers. The
sound of the Aleph amplifiers has been recognized world-wide as the most
natural obtainable from solid state amplifiers.

评述: 比尔兄,不想试试音乐传真的垫板?stable 1,好东西啊,我一口气买了3块,宽松、温
暖、丰润,解析力也大为提高。适合cd、前级。我垫在黑胶、前级和cd上,感觉升了几
级。拿到三位朋友家放毒,次次成功,三位全无幸免毒翻在地,乖乖交出银两买来解药。
哈哈。
