{"product_id":"sonifex-rb-hd2-dual-stereo-headphone-amplifier","title":"Sonifex RB-HD2 | Dual Stereo Headphone Amplifier","description":"\u003cp\u003eThe RB-HD2 is a high performance 2-way stereo headphone distribution amplifier for driving up to 2 pairs of professional stereo headphones from a single stereo or mono input. A switch on the rear panel enables the distribution of a mono signal to all four outputs (i.e. both earpieces of a pair of stereo headphones) via the left channel input. The stereo\/mono switch is located on the rear panel to prevent accidental knocking. The XLR-3 inputs are electronically balanced and can be wired unbalanced. There are two pre-set controls on the rear panel that adjust the level of the master input signal to the outputs. Each output is on a ¼” stereo jack socket and is designed to drive 150mW into 32 ohm to 600 ohm stereo headphones. The outputs are individually buffered with their own front panel volume control. A LED power indicator on the front panel displays the power supply connection. Stereo analogue balanced XLR inputs.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStereo analogue balanced XLR inputs.\u003c\/li\u003e\n\u003cli\u003e2 front panel headphone outputs.\u003c\/li\u003e\n\u003cli\u003eIndividual level controls for each output.\u003c\/li\u003e\n\u003cli\u003eMaster level control.\u003c\/li\u003e\n\u003cli\u003eStereo \/ mono feed selection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eAdding headphone outputs to mixer programme output.\u003c\/p\u003e\u003ch3\u003eProduct Category\u003c\/h3\u003e\u003cp\u003eHeadphone Amplifiers\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ch4\u003eAudio Specification\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e \u0026gt;20kΩ balanced bridging (main)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Input Level:\u003c\/strong\u003e +28dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Gain Range:\u003c\/strong\u003e -12dB to +20dB gain (pre-set pots)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Level:\u003c\/strong\u003e Drives 150mW into 32Ω to 600Ω headphones\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume Controls:\u003c\/strong\u003e -80dB to +11dB gain\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eConnections\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain Stereo Inputs:\u003c\/strong\u003e 2 x XLR 3 pin female (balanced, can be unbalanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 2 x ¼” (6.35mm) A-gauge 3-pole stereo jack sockets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains Input:\u003c\/strong\u003e Filtered IEC, switchable 110-120V, or 220-240V, fused, 9W max\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Rating:\u003c\/strong\u003e Anti-surge fuse 100mA 20 x 5mm (230VAC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Rating:\u003c\/strong\u003e Anti-surge fuse 250mA 20 x 5mm (115VAC)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eEquipment Type\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eRB-HD2:\u003c\/strong\u003e Dual stereo headphone amplifier\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003ePhysical Specification\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Raw):\u003c\/strong\u003e 48cm (W) x 10.8cm (D) x 4.2cm (H) (1U)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Raw):\u003c\/strong\u003e 19” (W) x 4.3” (D) x 1.7” (H) (1U)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Boxed):\u003c\/strong\u003e 53cm (W) x 20.5cm (D) x 6cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Boxed):\u003c\/strong\u003e 21” (W) x 8” (D) x 2.4”\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 1.35kg Gross: 2.0kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 3.0lbs Gross: 4.4lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSupport and Downloads\u003c\/h3\u003e\u003ch4\u003eHandbooks \u0026amp; Guides\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/ad56550c.delivery.rocketcdn.me\/wp-content\/uploads\/products\/RB-HD2\/redbox-05_hb.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRB-HD2 Handbook\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eBrochures\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/sonifex.co.uk\/brochures-guides\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eClick to visit the brochures page.\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eDeclarations\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/sonifex.co.uk\/support\/ce-ukca-declarations\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eClick to visit the declarations page.\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/sonifex.co.uk\/product\/rb-hd1\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRB-HD1 Stereo Headphone Amplifier\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eOfficial Links\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/sonifex.co.uk\/product\/rb-hd2\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eOfficial Product Page\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Sonifex","offers":[{"title":"Default Title","offer_id":53670180815189,"sku":"RB-HD2","price":445.08,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/6993\/3141\/files\/Sonifex_Sonifex_RB_HD2_Dual_Stereo_Headphone_Amplifier_01.jpg?v=1780662501","url":"https:\/\/tvpro.lt\/products\/sonifex-rb-hd2-dual-stereo-headphone-amplifier","provider":"tvpro.lt – Broadcast \u0026 Pro Video Equipment Online Store","version":"1.0","type":"link"}
