A typical application might be to provide common headphone feeds for guests in a radio studio, with a separately derived feed, perhaps including talk-back, for the presenter.\u003c\/p\u003e\n\u003cp\u003eThe main stereo input is on XLR-3 connectors on the rear panel which are electronically balanced and can be wired unbalanced. A stereo\/mono input select switch on the rear panel sums left and right outputs to provide a mono feed to the headphones. The unit can receive an override audio signal via a jack socket for each output channel. Plugging in the jack plug will divert the headphone output from the master audio signal to the audio present on the jack plug. The override audio inputs can also be individually configured as parallel outputs of the front sockets, by setting internal jumpers. The master volume control adjusts overall level of the 6 outputs and does not affect the level of channels using the override inputs. The master volume can be disabled by internal jumpers.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.sonifex.co.uk\/images\/redbox\/rb-hd6_block_diagram_598px.jpg\" alt=\"RB-HD6 Diagram\" width=\"500\" height=\"639\"\u003e\u003c\/p\u003e\n\u003cp class=\"caption\"\u003eRB-HD6 Block Diagram.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.sonifex.co.uk\/company\/logos-images\/productimages\/redbox\/rb-hd6_block_diagram_300dpi.jpg\" target=\"_blank\"\u003eSee larger image \u0026gt;\u003c\/a\u003e\u003c\/p\u003e\n\u003ctable width=\"590\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" class=\"table02\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003ch2\u003eTechnical Specification For RB-HD6\u003c\/h2\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003ch4\u003eAudio Specification\u003c\/h4\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"142\" height=\"21\"\u003eInput impedance:\u003c\/td\u003e\n\u003ctd width=\"448\"\u003e\u0026gt;20kΩ balanced bridging, \u0026gt;10kΩ unbalanced override\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eOutput Level:\u003c\/td\u003e\n\u003ctd\u003eDrives 150mW into 32Ω to 600Ω headphones\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eIndividual Volume Control:\u003c\/td\u003e\n\u003ctd\u003e-60dB to +18dB gain\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eMax Input Level:\u003c\/td\u003e\n\u003ctd\u003e+28dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eOverride Inputs:\u003c\/td\u003e\n\u003ctd\u003e+3dBu for full volume at +18dB gain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eMaster Vol Control:\u003c\/td\u003e\n\u003ctd\u003e±10dB gain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\" colspan=\"2\"\u003e\n\u003ch4\u003eConnections\u003c\/h4\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eMain Stereo Inputs:\u003c\/td\u003e\n\u003ctd\u003e2 x XLR 3 pin female (balanced, can be unbalanced)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eInsert Inputs\/Parallel Outputs:\u003c\/td\u003e\n\u003ctd\u003e6 x ¼” (6.35mm) A-gauge 3-pole stereo jack sockets (unbalanced)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eOutputs:\u003c\/td\u003e\n\u003ctd\u003e6 x ¼” (6.35mm) A-gauge 3-pole stereo jack sockets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eMains Input:\u003c\/td\u003e\n\u003ctd\u003eFiltered IEC, switchable 110-120V, or 220-240V, fused, 9W max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eFuse Rating:\u003c\/td\u003e\n\u003ctd\u003eAnti-surge fuse 100mA 20 x 5mm (230VAC)\u003cbr\u003eAnti-surge fuse 250mA 20 x 5mm (115VAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\" colspan=\"2\"\u003e\n\u003ch4\u003eEquipment Type\u003c\/h4\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eRB-HD6:\u003c\/td\u003e\n\u003ctd\u003e6 way stereo headphone distribution amplifier\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003e \u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\" colspan=\"2\"\u003e\n\u003ch4\u003ePhysical Specification\u003c\/h4\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eDimensions (Raw):\u003c\/td\u003e\n\u003ctd\u003e48cm (W) x 10.8cm (D) x 4.2cm (H) (1U)\u003cbr\u003e19” (W) x 4.3” (D) x 1.7” (H) (1U)\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eDimensions (Boxed):\u003c\/td\u003e\n\u003ctd\u003e58.5cm (W) x 22.5cm (D) x 7cm (H)\u003cbr\u003e23” (W) x 8.9” (D) x 2.8” (H)\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003eNett: 1.35kg Gross: 2.0kg\u003cbr\u003eNett: 3lbs     Gross: 4.4lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Sonifex","offers":[{"title":"Default Title","offer_id":49434502136055,"sku":"RB-HD6","price":740.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0422\/1291\/7402\/files\/rb-hd6_600px.jpg?v=1739794657","url":"https:\/\/www.305broadcast.com\/products\/sonifex-rb-hd6-6-way-headphone-distribution-amplifier","provider":"305broadcast","version":"1.0","type":"link"}
