LUXMAN C-1000

Commentary

A control amplifier using transistors.

The equalizer uses a cascode, differential and direct coupling method to improve linearity, stability and signal-to-noise ratio in the high frequency range.
In addition, a class A inverted Darlington push-pull configuration is adopted for the final stage so that it is not affected by the load condition connected after the equalizer stage. In addition, a constant current drive is provided at important points to improve the linearity of the transistor itself and to improve the bare loop gain to ensure the full differential function.

The intermediate amplifier section and tone control section also employ the cascoded direct-coupled method to improve linearity, stability and signal-to-noise ratio in the high-frequency range.
The tone control part uses LUX system NF type with 3-point switching of bending point frequency, and it is also possible to defeat.
The output section uses a two chip emitter-follower circuit, and by using one chip for constant current drive, linearity is improved over a wide band.

Highly reliable CAN type transistors are used for all stages, and ± 2 power supply system with constant voltage is used for all stages.
