The distance range is about 30 cm. Additionally the module is equipped with a Gate output with adjustable threshold level. Controls\/Inputs\/Outputs: antenna input, offset (knob for zero adjust), 2 x CV out, 2 x LED (for CV control positive\/negative and zero offset adjust)\u003cbr\u003eTo simulate the original Theremin two A-178, a VCO (e.g. A-110) and a linear VCA (e.g. A-130 or A-132) are required. But of course the A-178 can be used to control other functions in the A-100 (e.g. filter frequency, modulation depth and\/or speed, tempo, attack\/decay time and so on).\u003cbr\u003eThe \u003cspan class=\"492123115-11012008\"\u003eCV output voltage of the A-178 can range - according to the setting of the front panel controls - from -10V...+10V.

The module has to be disassembled. An additional hole for the new BNC connector has to be drilled or punched into the panel e.g. right from the existing antenna socket above the Offset control (the existing hole of the 3.5 mm miniature socket cannot be used for the BNC connector). Then the module has to be assembled again and the new BNC connector has to be connected to the old socket. Pay attention that an isolated version of the BNC socket has to be used.

Antenna and hand form a variable capacitor with a very small capacity in the pico Farad range. The electronics of the module is puzzled out just for this capacity range. If a cable is added the capacity range changes totally and the module will no longer work ! But it's possible to mount the complete module with antenna at the desired position, e.g. into a small case that holds one or two of the modules. For this a longer bus cable is required. If you are not able to manufacture such a cable yourself we may offer a suitable cable upon request. Please tell us the desired length for a quotation of such a cable.\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eSimilar control voltage modules:\u003ca href=\"http:\/\/www.doepfer.de\/a179.htm\"\u003e\u003cbr\u003e\u003c\/a\u003e\u003ca href=\"http:\/\/www.doepfer.de\/a198.htm\"\u003eTrautonium\/Ribbon Controller A-198\u003c\/a\u003e \/ \u003ca href=\"http:\/\/www.doepfer.de\/a177.htm\"\u003eFoot-Controller A-177-2\u003c\/a\u003e \/ \u003ca href=\"http:\/\/www.doepfer.de\/a174.htm\"\u003eJoy Stick A-174-1\u003c\/a\u003e \/ \u003ca href=\"http:\/\/www.doepfer.de\/a1742.htm\"\u003eWheels Module A-174-2\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd align=\"left\" valign=\"top\"\u003e\u003chr size=\"1\"\u003e\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd colspan=\"2\" align=\"left\" valign=\"top\"\u003e\r\n\u003cp\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eBreite\/Width: 8 TE \/ 8 HP \/ 40.3 mm\u003cbr\u003e\u003c\/span\u003e\u003cspan style=\"color: #000000; font-family: Arial; font-size: small;\"\u003eTiefe\/Depth: 40 mm (gemessen ab der Rückseite der Frontplatte \/ measured from the rear side of the front panel)\u003c\/span\u003e\u003c\/p\u003e\r\n\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e","brand":"DOEPFER","offers":[{"title":"Default Title","offer_id":41517911605421,"sku":"doepfer-a-178v-vintage-edition","price":138.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/products\/a-178v.jpg?v=1651483769","url":"https:\/\/www.detroitmodular.live\/products\/doepfer-a-178v-theremin-control-voltage-source-v2-vintage-edition","provider":"Detroit Modular","version":"1.0","type":"link"}
