It is available with a pro-audio EQ (Option P) for high fidelity operation or with the standard EQ which emphasizes the frequencies that define speech intelligibility for auditory assistance and other personal communication applications. The AutoSmart-Tuning (AST) function makes it possible for the listener to use the same receiver to attend multiple programs at church, school classes, tour guide presentations, and for personal auditory assistance.\u003c\/p\u003e \u003cp\u003eThis unique receiver will automatically turn itself on and initiate its AutoSmart-Tuning process when the earphone is plugged in. The PR-75a receiver selects the closest appropriate transmitter in its vicinity and then sets itself to this channel. A convenient, one-button tuning control will cause the PR-75a to reinitiate the AutoSmart-Tuning process allowing the receiver to re-tune to a different compatible transmitter at venues where multiple transmitters are in use. Additionally, the PR-75a can be programmed for a set frequency or for a preset group of frequencies that can be accessed in sequence using the one-button tuning control (Program B).\u003c\/p\u003e\u003ch2\u003eFeatures:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUnique Self-Tuning\u003c\/li\u003e\n\u003cli\u003e100 Hours Battery Life\u003c\/li\u003e\n\u003cli\u003eStereo or Mono Headsets\u003c\/li\u003e\n\u003cli\u003eFlash Memory Technology\u003c\/li\u003e\n\u003cli\u003eRugged and Durable Design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAudio Output: Headset output 200 mW average (Impedance as low as 16 ohm)\u003c\/li\u003e\n\u003cli\u003eConnectors:\u003c\/li\u003e\n\u003cli\u003eStereo\/mono 3.5 mm audio output\u003c\/li\u003e\n\u003cli\u003e2.5 mm stereo connector for I\/O data programming\u003c\/li\u003e\n\u003cli\u003eMulti-Function LED Indicator:\u003c\/li\u003e\n\u003cli\u003eChannel-seeking\u003c\/li\u003e\n\u003cli\u003eReceived signal\u003c\/li\u003e\n\u003cli\u003eNo signal\u003c\/li\u003e\n\u003cli\u003eLow battery\u003c\/li\u003e\n\u003cli\u003eControls:\u003c\/li\u003e\n\u003cli\u003eVolume control (50 dB range)\u003c\/li\u003e\n\u003cli\u003eAutomatic turn-on when headphone is plugged in and turn-off when headphone is removed\u003c\/li\u003e\n\u003cli\u003eOne-button channel control (AST)\u003c\/li\u003e\n\u003cli\u003eAudio Frequency Response: 100 Hz to 10 kHz\u003c\/li\u003e\n\u003cli\u003eDeviation Acceptance: Up to ±50 kHz\u003c\/li\u003e\n\u003cli\u003eAntenna: Integral with headphone cable (no external antenna)\u003c\/li\u003e\n\u003cli\u003ePower Requirements: 2 AA 1.5 volt alkaline batteries or rechargeable Ni-MH (NH-2400)\u003c\/li\u003e\n\u003cli\u003eDimensions: 1 1\/6\" x 2 1\/2\" x 3 1\/4\" (27 mm x 57 mm x 83 mm)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Comtek","offers":[{"title":"Default Title","offer_id":42490710261938,"sku":"CTK PR75A","price":271.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/8122\/2322\/products\/Comtek-PR-75a.jpg?v=1680110957","url":"https:\/\/www.performanceaudio.com\/products\/comtek-pr-75a-autosmart-tuning-receiver","provider":"Performance Audio","version":"1.0","type":"link"}
