ONKYO Integra T-466NII
¥ 49,000 (released in 1975)
Commentary
An FM/AM tuner designed with an emphasis on basic performance.
A low-noise FET and a frequency-linear four link varicon are used in the front-end section to achieve 1.9 μ V (IHF) interference rejection characteristics.
In addition, the Narrow-type AFC circuit, which increases frequency stability, is combined with the use of a local variable capacitor and detector, which are less affected by temperature and humidity drift, to prevent tuning deviation.
A linear-phase-type ceramic filter and a differential-type IC are used in the IF section to obtain sufficient limiter effect.
The MPX section uses a PLL circuit that is less susceptible to degradation due to temperature and humidity. It is combined with a low-pass filter that improves internal separation to improve separation.
The tuning mechanism is the same as that of the T-455NII.
Equipped with a multi-path output terminal that is convenient for determining antenna position.
Equipped with a 4-ch detection output terminal capable of supporting FM4ch broadcasting.
Outputs are equipped with a Route 3 of level variable / level fixed and DIN terminals.
A triple tune filter is used in the IF stage of the AM part to increase the selectivity.
