LEAK 2200
a price point -- unknown (around the 1975 time)

The Integrated Amplifier from which the tradition since point one was inherited.

The output stage of pure complimentary OCL and the constant current drive type Class-A driver stage are used for a power amplifier part, and it is designed carry out the stable operation influenced by neither a temperature change, nor a load variation, a shocking noise, etc. by applying the deep stable direct current NFB.

The protection network which protects a loudspeaker and an output transistor in case of outages, such as output-terminal short-circuit and an excessive input, is prepared.

Since the circuitry which has a difference input in the equalizer stage is used and the direct current NFB is applied to the overall, the operation stabilized strongly shockingly has been realized.

functionalities, such as the BTL circuitry which even a switchpoint comes out and can take out a monophonic output, and a loudspeaker matrix switch which can take out the hole tone effect, are carried.
