The module will trigger on any program material, with paging sources being the most common. The TX-PCR1 includes both an open-collector SLAVE output to control other modules or equipment and a DPDT high power switching relay suited to switching speaker loads. The amplified audio source is connected using a detachable terminal block. A front-panel switch is provided to select the source type: 25 V, 70 V or 100 V. The 25 V setting may be used for an 8 ohm, 75 Watt maximum, amplified source. Input sensitivity is adjusted on a single-turn trimmer. In the clockwise position, the SENSITIVITY trigger threshold is 30 dB below the switch-selected constant voltage. A red LED illuminates whenever the audio level exceeds the trigger threshold, facilitating the sensitivity adjustment.\u003c\/p\u003e","brand":"AVGear.com","offers":[{"title":"Default Title","offer_id":44835141255367,"sku":"C1682-93","price":79.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/7865\/6199\/files\/RDLTX-PCR1PagingControlledRelaySwitchesBetween25_70and100VInputs-1_8d054633-3107-4970-8d5f-935b9323b36e.jpg?v=1742833726","url":"https:\/\/www.avgear.com\/products\/rdl-tx-pcr1-paging-controlled-relay-switches-between-25-70-and-100v-inputs-c1682-93","provider":"AVGear.com","version":"1.0","type":"link"}
