{"product_id":"sonifex-rb-ma1-single-microphone-amplifier","title":"Sonifex RB-MA1 | Single Microphone Amplifier","description":"\u003cp\u003eThe RB-MA1 consists of a low noise microphone pre-amplifier for converting mic level signals to line level, or for driving long lines from microphones to mixing equipment. The connections and controls are on the rear panel. The microphone input is an XLR-3 type and is electronically balanced. The gain for the input can be adjusted by a recessed pre-set potentiometer which allows for the use of both dynamic and powered microphones. The line output is of an XLR-3 type and is electronically balanced. It can be wired unbalanced by grounding the non-phase signal, allowing you to feed both balanced and unbalanced equipment. There is a switch to control a high pass filter (low frequency roll-off at 125Hz) and to provide phantom power at +48V to the connected microphone. Balanced Neutrik XLR mic input.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBalanced Neutrik XLR mic input.\u003c\/li\u003e\n\u003cli\u003eBalanced Neutrik XLR line output.\u003c\/li\u003e\n\u003cli\u003eMic input gain adjustment.\u003c\/li\u003e\n\u003cli\u003e+48V phantom power.\u003c\/li\u003e\n\u003cli\u003eHigh pass (rumble) filter.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eTo amplify additional microphones in a studio talks area, court room microphone amplification.\u003c\/p\u003e\u003ch3\u003eProduct Category\u003c\/h3\u003e\u003cp\u003eMicrophone Amplifiers\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ch4\u003eAudio Specification\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Input Level:\u003c\/strong\u003e -10dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Output Level:\u003c\/strong\u003e +28dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Frequency Roll-Off:\u003c\/strong\u003e 125Hz @ 6dB\/octave\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eE.I.N.:\u003c\/strong\u003e 130dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Mode Rejection:\u003c\/strong\u003e \u0026gt;60dB typically\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz to 20kHz ±0.1dB (600Ω load, ref 1kHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 2kΩ nominal balanced\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e \u0026lt;50Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain Range:\u003c\/strong\u003e Adjustable 36dB to 75dB gain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion:\u003c\/strong\u003e 0.01% THD @ 1kHz, ref +8dBu output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhantom Power:\u003c\/strong\u003e 48V\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eConnections\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 1 x XLR 3 pin female (Balanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 1 x XLR 3 pin male (Balanced, can be unbalanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains Input:\u003c\/strong\u003e Filtered IEC, switchable 110-120V, or 220-240V, fused, 6W 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-MA1:\u003c\/strong\u003e Single microphone 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 28cm (W) x 10.8cm (D) x 4.2cm (H) (1U)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Raw):\u003c\/strong\u003e 11” (W) x 4.3” (D) x 1.7” (H) (1U)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Boxed):\u003c\/strong\u003e 36cm (W) x 20.5cm (D) x 6cm (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Boxed):\u003c\/strong\u003e 14.2” (W) x 8” (D) x 2.4” (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 0.90kg Gross: 1.35kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Nett: 2.0lbs Gross: 3.0lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSupport and Downloads\u003c\/h3\u003e\u003ch4\u003eHandbooks \u0026amp;
