Quartz Digital Synthesizer Tuner TX-3
The TX-3 has everything you've come to expect in a high quality quartz digital synthesizer tuner, and then some. Features include preset of up to 8 FM and 8 AM stations for instant one-touch tuning, and automatic next station tuning at the push of a button. Manual tuning is provided through a rotary knob which allows total control and surprisingly accurate Operation when compared to the awkward up/down tuning controls found an less innovative tuners. Auto IF (Intermediate Frequency) Bandwidth assures the finest sound from each and every station received. Normally set wide for the highest fidelity obtainable, narrow bandwidth is automatically set at the very instant that sufficient interference is detected. This assures an absolute minimum of reception distortion. dbx SNR noise reduction, using the same principle that our landmark "Studio` use noise reduction systems introduced, eliminates hiss and annoying high frequency noise which can be heard in virtually all FM programming. The Optimum in FM reception is yours thanks to a variable frequency single-pass processor that removes only unwanted noise, without affecting frequency response or separation of the music signal. Finally, in the event that the signal is too weak, an Auto Hi-Blend mode is automatically engaged to eliminate excessive noise.
Versatile controls such as mono/stereo option, muting, and output level are included, along with full remote control capability through the CX-3 MkII control amplifier's remote controller. Assuring a pleasing blend with this full System of dbx components, the TX-3 also features wooden side panels.
