Dynamic 150 + 150 Watts Power Output, Generous High-power Design


The Spec-4 employs DC construction which excludes capacitors from the NFB circuits and uses a dual transistor differential amplifier with a current mirror circuit in the 1st stage. This provides a stable operation and also high gain over a wide frequency range. The pre-driver stage is a class A amplifier circuit with a regulated current circuit for the load. This makes for high-gain amplification with superior linearity. Furthermore, there is an overdrive limiter and power limiter circuit which is designed to protect the power transistors and make for added reliability.


The power stage employs a 3-stage Darlington pure complementary parallel SEPP circuit.


The SPEC-4 delivers Continuous Power Output of 150 watts per channel, min. RMS, at 8 ohms from 20 Hertz to 20,…
