{"product_id":"rapcohorizon-sl-4","title":"RapcoHorizon SL-4 Rack Mount 4-Channel Active DI Box","description":"\u003cp\u003eThe RapcoHorizon SL-4 is engineered for live and studio environments where multiple unbalanced Hi-Z sources — keyboards, drum triggers, synths, or other line-level instruments — must be converted to balanced Lo-Z signals for a console or stagebox. Built into a cold rolled steel chassis for superior RF shielding and long-term road durability, it occupies a single rack space and eliminates the need to stage multiple individual DI boxes across a show or session.\u003c\/p\u003e\u003cp\u003eEach of the four channels is equipped with a front-panel Hi-Z input, a loop-thru jack for monitoring or amp feeds, a ground lift switch to eliminate hum from ground loops, and a -20dB pad switch that accommodates both instrument-level and line-level sources without signal overload. The rear panel provides a Hi-Z 1\/4\" input\/output, an XLR male balanced Lo-Z output, and a balanced 1\/4\" output per channel, delivering flexible patching configurations that simplify complex multichannel setups.\u003c\/p\u003e\u003cp\u003eFor production teams managing keyboardists, electronic drum rigs, or playback systems, the SL-4 consolidates four channels of transformer-isolated DI conversion into a clean, rack-integrated solution. It delivers the same per-channel functionality as four individual SL-2 direct boxes in a fraction of the rack footprint, making it a practical choice for touring, installed sound, and broadcast environments where efficiency and signal integrity are both required.\u003c\/p\u003e","brand":"RapcoHorizon Int RHC Holding","offers":[{"title":"Default Title","offer_id":52446650826936,"sku":"64375","price":489.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/64375_RAPHOR-SL-4_ALT01.jpg?v=1783628816","url":"https:\/\/soundpro.com\/products\/rapcohorizon-sl-4","provider":"SoundPro","version":"1.0","type":"link"}
