Luxman T-110

 Ultimate High-Fidelity Stereo Component Model T-110 FM/FM-MPX Tuner

New compact tuner for FM only reception. An epoch-making new approach to styling departs from the conventional concept of tuners which have normally treated product dimensions to equal those of the matching amplifier.

Unlike conventional tuners, the entire dial plate is designed as a unity with tuning and signal strength meter - in other words tha dial scale isplaced in the meters.

The dial scale and letters are of etched aluminium foil. An additional feature is in the special tuning pointer which blinks at interstation settings and lights up when stations are tuned.

 Features of circuitry

Included in the front end is a 5 gang variable capacitor, a low distortion oscillator and MOS FETs in the RF amp and mixer stages, which ensures an amazing characteristic exceeding 100 dB in all kinds of rejection ratio such as image, spurious response and IF.

To obtain good selectivity and low distortion at the same time, the IF stage employs 2 sets of 4-complement linear phase LC block filter and a cerammic filter.

The combination of LC block filter and a ceramic filter compensates mutual delay time and helps lower distortion and increases selectivity. Specifically, the distortion figure is below 0,08% 9both streo and monaural) -  unprecedented in tuners in this price bracket.

Also, selectivity is excellent in the event that both the desired signals and interfering one are stereo.

Other, IF stages are composed of ICs of large scale integration.

 The MPX circuit uses PLL ICs .

A special PLL IC is provided which yields low distortion equivalent to that of discrete circuit adoped in the T300.

An IC for pre amp is used in the last stage of the audio amp to achieve the lowest possible distortion.

Additional features are high output multi-path detector circuit, 4-CH output terminal and attenuator circuit for RF input.

In addition, to remove the unpleasant "thump" noise at the time of on/off operation of power switch, time delay is provided until the circuit is put into operation.
