Luxman R-5030

AM/FM Tuner-Amplifier

A new (in 1981) budget tuner amplifier. Computer Analyzed Tuning (CAT) system establishes the optimum receiving condition automatically. Amplifier section employs the Duo-Beta Circuit for improved audio performance.

Features:

Flasher Tuning System Indicator

In case of FM reception, this indicator shows the direction of tuning. When a broadcasting station is coming near, the indicator begins flashing. Turn he tunning knob slowly to the direction shown by the indicator, and the flashing ceases at a point where the precise tuning point is obtained. At this time, the indicator shows the signal strength of the station  just tuned in. When 3 or more indicators light up, stble reception in stereo mode is feasible.

C.A.T. off Switch

Thanks to our innovative C.A.T. (Computer Analized Tuning) circuitry, this tuner-amplifier always provides an optimum reception according to the ambient conditions. Specifically, the anti-birdie and noise canceller circuits are sensing the electric field strength, interference by other stations, etc.
