{"product_id":"rdl-st-vca3-voltage-controlled-amplifier","title":"RDL ST-VCA3 Voltage Controlled Amplifier","description":"\u003cp\u003eThe ST-VCA3 is used in applications requiring smooth audio level control from a remote control panel, potentiometer or dc voltage (0 to 10 V). Installation in series with the audio input of a power amplifier allows remote control of that amplifier™s level. For installations where it is preferred to keep the audio localized in the rack, audio controls are extended outside the rack from the ST-VCA3. Many installations benefit from avoiding long-term potentiometer wear from audio running through the potentiometer. An ST-VCA3 with external dc control provides virtual immunity from scratchy audio. Audio\/video system control units often provide 0 to 10 Vdc control outputs that can directly control audio levels using an ST-VCA3. The ST-VCA3 is primarily intended for line-level attenuation a high quality utility microphone preamplifier is included in the module. If remote control of a microphone preamplifier is desired, such as a wall mounted level control for a microphone jack, the ST-VCA3 may serve as a remote controlled microphone preamplifier.\u003c\/p\u003e\u003cul\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cli\u003eAudio Level Control from a DC Voltage\u003c\/li\u003e\n\u003cli\u003eAudio Level Remote Control\u003c\/li\u003e\n\u003cli\u003eTwo Wire with Shield or Three Wire Control\u003c\/li\u003e\n\u003cli\u003eVCA with Microphone or Line Level Input\u003c\/li\u003e\n\u003cli\u003eVCA with Line-Level Output\u003c\/li\u003e\n\u003cli\u003eVCA with LED Metering of Operating Level\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":49567624852,"sku":"237933","price":669.52,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2241\/9163\/products\/4b8086a3a10da132655b4dd9877957fe.jpg?v=1504263840","url":"https:\/\/collection-import-export.myshopify.com\/products\/rdl-st-vca3-voltage-controlled-amplifier","provider":"collection-import-export","version":"1.0","type":"link"}
