Solid State AM/FM MPX Stereo Receiver
Highest quality, low-noise silicon transistor are used in the advanced circuitry of the new SX-9000, the world's first receiver to include its own reverberation amplifier. There's plenty of power - 240 big watts (at 4 ohms) to handle any program material with ease. Sensitivity is 1,6 µV, a figure that ensures you'll get more stations, more clearly, always. The high-performance SX-9000 isreally versatile; you can use two tape decks with it, two record players, two headsets, two microphones. The microphone mixing feature makes this a receiver that invites your participation, in mono or stereo. You,, too, make music with the SX-9000. there's also a switch for selection of tone colors, in addition to the normal bass and treble controls. Tape-to-tape dubbing is simplicity itself.
The SX-9000 is the receiver that gives you circuitry on a par with professional designs plus the greatest variety of audio enjoyment available anywhere.
Features
A Multi-Purpose, Easy-to-Use Design
The SX-9000 was designed to give you a high degree of versatility in operation. You can, for example, use two microphones, tape decks and two headsets, with the SX-9000. all controls are rationally placed for easy use. The circuitry is quite advanced, on a par with professional designs.
Clean-Lined, Contemporary Appearance
The SX-9000 looks good, too. The front incorporates a folding panel that adds to its distinctive design. When in operation, the smoked glass dial window lights up with subdued illumination, and the source also lights up for quick identification.
High Performance Tuner
The SX-9000 employs the latest circuitry, including FET and ICs. The result is a professional receiver of exceptional sensitivity and stability.
Pre-Set Tone Colors
In addition to the normal bass and treble controls, there is a 4-position tone color selector knob. This provides quick switching from "flat" to "soft", "bass" or "vivid". These characteristics are symbolized in an illuminated window in the dial face.
Tape-to-Tape Monitoring
Two buttons on the front panel allow easy, one-touch monitoring of tapes "A" or "B" when you use the SX-9000 to copy directly from one tape to another.
Foolproof Microphone Use
When either microphone knob is set to Off, the unit operates in parallel to provide monophonic signals for both speakers without having to set the mode switch.
Reverberation Effect.
Also included is a reverberation effect knob. The degree of "echo" is easily read in the "Reveberation" window in the dial face.
Special "Overload Protection"
You can play up to three different pairs of speaker systems through the SX-9000 in combinations A, B, C, A+B, A+C, B+C. If all three are accidentally turned on, however, the "Overload Protection" goes into action and the speakers are automatically shut off.
Earphone versatility
Because the SX-9000 has two "Earphones" output jacks, two people may listen simultaneously with earphones withpout having to go through an accessory junction box.
