For your convenience, the RD500\/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB \/ octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.The RD500\/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD500\/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer output directly from the driver’s seat.\u003cdiv style=\"margin-top:40px; padding:30px; border:3px solid #008060; border-radius:15px; text-align:center; background:#fff;\"\u003e\r\n                \u003ch2\u003eAcquista su Car Audio Centre\u003c\/h2\u003e\r\n                \u003cdiv style=\"font-size: 32px; font-weight: bold; color: #333; margin-bottom: 20px;\"\u003e299 GBP\u003c\/div\u003e\r\n                \u003ca href=\"https:\/\/www.awin1.com\/cread.php?awinmid=67434\u0026amp;awinaffid=356591\u0026amp;ued=https%3A%2F%2Fcaraudiocentre.co.uk%2Fproducts%2Fm-jl-audio-jlrd500-1%3Fvariant%3D45592402886937\" target=\"_blank\" rel=\"nofollow\" style=\"display:inline-block; background:#008060; color:#fff; padding:18px 40px; font-size:20px; font-weight:bold; text-decoration:none; border-radius:10px;\"\u003e\r\n                    GO TO OFFERS\r\n                \u003c\/a\u003e\r\n               \u003c\/div\u003e","brand":"Car Audio Centre","offers":[{"title":"Default Title","offer_id":58226380177789,"sku":"45592402886937","price":299.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0937\/0812\/4541\/files\/jl-audio-41780641726745.jpg?v=1780087856","url":"https:\/\/search.negozishop.it\/products\/jl-audio-rd500-1-rd-500w-monoblock-class-d-subwoofer-amplifier","provider":"Search Negozishop","version":"1.0","type":"link"}
