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.

The XLR-3 line output is electronically balanced and can be wired unbalanced by grounding the non-phase signal, allowing you to feed both balanced and unbalanced equipment. For each channel there are independent switches to control a high pass filter (low frequency roll-off at 125Hz) and to provide phantom power at +48V to the connected microphone. An LED power indicator on the front panel displays the power supply connection. 2x Balanced Neutrik XLR mic input.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2x Balanced Neutrik XLR mic input.\u003c\/li\u003e\n\u003cli\u003e2x Balanced Neutrik XLR line output.\u003c\/li\u003e\n\u003cli\u003eFront panel level adjustment.\u003c\/li\u003e\n\u003cli\u003eFront panel bright LED metering.\u003c\/li\u003e\n\u003cli\u003eCoarse mic 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, converting a mic to a line signal where mic and amp are a long distance apart.\u003c\/p\u003e\u003ch3\u003eProduct Category\u003c\/h3\u003e\u003cp\u003eMicrophone Amplifiers\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ch4\u003eAudio Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Input Level:\u003c\/strong\u003e +4dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Output Level:\u003c\/strong\u003e +28dBu\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 Balanced\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\u003eGain Range:\u003c\/strong\u003e Adjustable 12dB to 80dB gain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eE.I.N:\u003c\/strong\u003e -128dBu, 20kHz BW, max gain, Rs=200Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion:\u003c\/strong\u003e \u0026lt;0.01%, +8dBu, 20Hz – 20kHz, 40dB gain, 20kHz bandwidth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Mode Rejection:\u003c\/strong\u003e \u0026gt;66dB @ 1kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhantom Power:\u003c\/strong\u003e 48V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz to 20kHz +0\/-0.2dB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eConnections\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 2 x XLR 3 pin female (Balanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 2 x XLR 3 pin male (Balanced, can be unbalanced)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains Input:\u003c\/strong\u003e Filtered IEC, 110V-120V, or 220-240V switchable, fused, 9W maximum\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-MA2G:\u003c\/strong\u003e Dual microphone amplifier with gain\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003ePhysical Specifications\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 58.5cm (W) x 22.5cm (D) x 7cm (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (Boxed):\u003c\/strong\u003e 23” (W) x 8.9” (D) x 2.8” (H)\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;

Programme feeds, auxiliary feeds and a talkback feed can be taken and monitored. The RB-MTV1 has four inputs and two outputs. It has a mono microphone input on XLR with switched coarse gain and variable fine gain control using a multi-turn preset potentiometer to give an overall gain range from +20dB to +80dB. There is also a switched LF rumble filter, switched +48V phantom power and switched level limiting control. A rear-panel multi-turn preset potentiometer allows adjustment of the threshold at which the limiter begins to operate, from -8dBu to +26dBu. There is an indication of the limiter activity using a blue LED and the microphone level is monitored by a simple 5 LED meter. The meter can be configured to either show the MIC signal activity in normal operation, i.e. when TALK is pressed the meter is off, or the meters can permanently show the MIC activity even when the TALK button is on or the MIC button is off.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWide mic input gain range.\u003c\/li\u003e\n\u003cli\u003eHigh pass filter, +48V phantom power.\u003c\/li\u003e\n\u003cli\u003eSwitchable level limiter with threshold control.\u003c\/li\u003e\n\u003cli\u003eMic level metering.\u003c\/li\u003e\n\u003cli\u003e'Lazy' talkback input\/output \u0026amp;
