{"product_id":"sonifex-cm-lur1-balanced-to-unbalanced-audio-converter","title":"Sonifex CM-LUR1 | Balanced to Unbalanced Audio Converter","description":"\u003cp\u003eThis product allows the connection of a stereo balanced line input via RJ45 with StudioHub+™ pinout to a stereo unbalanced output on stereo phono connectors. It is transformer balanced, with a 2:1 ratio, so 6dB of attenuation is added to the input to help interface with the lower signal levels associated with consumer outputs. This unit is a passive version of the RB-LU4 (though only 1 x stereo channel), and provides you with an alternative to having to interface a balanced output to an unbalanced input via specialist cables (either by shorting the non-phase to ground or disconnecting it). It is particularly useful where a shared balanced audio feed needs interfacing to an unbalanced input on one or more pieces of equipment. Using a CM-LUR1 or CM-LUX1 galvanically isolates the audio, allowing you to connect via phono cables to an unbalanced input without compromising the distributed feed. The stereo analogue input is on a female RJ45 connector with the following standard StudioHub+™ pin assignments:\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStereo balanced line input via RJ45 with StudioHub+™ pinout.\u003c\/li\u003e\n\u003cli\u003eStereo unbalanced output on stereo phono connectors.\u003c\/li\u003e\n\u003cli\u003eTransformer-balanced input with 2:1 ratio.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eCreates a connection of a stereo balanced line input via RJ45 with StudioHub+™ pinout to a stereo unbalanced output on stereo phono connectors.\u003c\/p\u003e\u003ch3\u003eProduct Category\u003c\/h3\u003e\u003cp\u003ePassive Converters\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ch4\u003eAudio Specification\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput\/Output Level Ratio:\u003c\/strong\u003e 02:01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput\/Output Impedance Ratio:\u003c\/strong\u003e 04:01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Input Level:\u003c\/strong\u003e +28dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Output Level:\u003c\/strong\u003e +22dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz to 20kHz, +0\/-0.5dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise:\u003c\/strong\u003e \u0026lt;-115dBu A-wgtd\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion Ref +8dBu (Output):\u003c\/strong\u003e \u0026lt;0.01%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Mode Rejection:\u003c\/strong\u003e \u0026gt;80dB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eConnections\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced Line Input:\u003c\/strong\u003e 1 x RJ45 female StudioHub+™ pinout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnbalanced Line Output:\u003c\/strong\u003e 2 x RCA phono connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eEquipment Type\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCM-LUR1:\u003c\/strong\u003e Balanced to unbalanced audio converter, RJ45 input\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003ePhysical Specification\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Raw):\u003c\/strong\u003e 7.7cm (W) x 8.3cm (D) x 4.2cm (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Raw):\u003c\/strong\u003e 3.0” (W) x 3.3” (D) x 1.7” (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 0.22kg Gross: 0.33kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 0.49lbs Gross: 0.73lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSupport and Downloads\u003c\/h3\u003e\u003ch4\u003eHandbooks \u0026amp;
