Description
Very nice deck w/ low hours that plays for a few seconds w/ sound then shuts off. It does not F/F or Reverse as it needs 2 belts. But here I own a few fine examples left over. These are not the run of the mill out of the corner shop, craigs list, social media listing nor garage sale much less out of a trunk. This has been retired like everything pictured yet this for the top tape deck only and no it was never played on top of a power amp. I am... and I am (sorry as some may assume so with the last picture) and I will tell you as a past owner I have seen far worse starting to pioneering a true Incorporated Audio salon with vintage LPs. And a Hard rock Cafe level of posters, autographs, gold record awards to rare tubes, vintage guitars & amps, vintage synthesizers to recording equipment. But mostly high-end audio. Super GX Heads Usher in The Age of Metal TapeSuperficial modifications would have been totally inadequate to bring about the greatly improved performance achieved in the GX-F90. for this, Akais engineers went to the heart of the matter - the heads. The Super GX Head follows in the tradition of the immensely successful GX and new GX heads. It employs improved crystal ferrite as the core material, a super-hard substance which provides longer head and tape life. The heads of the 3-head system maintain optimum individual gap widths for better recording and playback characteristics with virtually no azimuth loss. Another advantage is that it enables direct tape monitoring. All this makes the Super GX Head ideal for metal tapes, with their greater dynamic range and improved Signal-to-Noise Ratio. Greater performance is obtained from conventional tapes, too. Two-Motor System for maximum Stability.High torque and minimal ripple, resulting in Wow and Flutter of less than 0,08 (DIN) are the major advantages of the GX-F90s transport mechanism. The Direct Capstan Drive system employs a coreless/FG Servo DC motor incorporating a Sample-and-Hold circuit for the capstan and a coreless DC servo-controlled motor for the reel drive. FL Display BAR MetersReflecting the latest trend in electronics, the conventional needle-type level meter has been replaced in the GX-F90 by a 48-segment fluorescent meter. Using 2 colours to indicate levels below and above 0 dB, it shows either the peak level or VU reading at the press of a button. The advanced digital circuitry provides level readings of much higher accuracy than the mechanical type. Playback - Its All AutomaticLet the instant Programme Locating System find the song you want to play. The system detects the beginning of the song by the volume level and the time constant and then commences playback automatically. The song can also be played repeatedly by setting the index counter to 000 and pressing the Repeat and Memory buttons. For continuous playback, press the Repeat button and at the end of the tape it will rewind to the beginning and resume playback. Illuminated IC Logic Control ButtonsThe feather-touch logic controls light up when touched. And with the Pause button on, when you press a mode button, the button will flash, to indicate the next mode. Whats more, you can switch directly from one mode to another without having to press the Stop button. Operating the deck is thus exceptionally fast and simple Calibration Tone Switch and AdjustersA Cal Tone button is provided which activates a built-in oscillator to supply a 400 Hz recording signal for recording calibration adjustment. Use this reference signal when performing re-calibration with the two Rec Cal adjusters to match the characteristics of the tape being used. An especially useful feature when making Dolby NR recordings. Dolby NR System and MPX FilterMuch has been written about the unique Dolby NR system, and how it greatly improves the sound of cassette tapes. It is exemplified by the GX-F90s Dolby NR system which works by raising low level signals prior to recording and then lowering them proportionately on playback. This results in sharply reduced tape hiss and an improved Signal-to-Noise Ratio of up to 10 dB above 5 kHz. The Dolby effect can be monitored during recording to cut the disturbance caused by the 19 kHz pilot signal during FM stereo broadcast recording with Dolby NR system, this deck ha an MPX Filter Switch. The ability to turn off the filter at all other times ensures full wide range frequency response. The Akai A.D.R. SystemThis system designed by Akai automatically adjusts recording equalization at high frequencies while at the same time suppressing intermodulation distortion Sound that is crystal clear over the entire frequency band is obtained.
