The GS-HA008 builds on the GSGH2s specification and features to offer a modern robust portable twin headphone amplifier to supercede the GSGH2. \u003c\/p\u003e\n\u003cp\u003eThe GS-HA008 is a very useful twin headphone amplifier. It has wwo independent input channels that can be routed separately to left ear, right ear, or both, across both headphone amplifiers. Each input channel has individual coarse gain controls and each headphone amplifier has separate left\/ right headphone volume controls.\u003c\/p\u003e\n\u003cp\u003eFor looping in large numbers, there is audio and power pass through. This makes the GS-HA008 suitable for audio monitoring in a dense environment such as an orchestra, where units can simply be looped together.]\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwo independent stereo headphone amps\u003c\/li\u003e\n\u003cli\u003eTwo balanced input feeds common for both amps\u003c\/li\u003e\n\u003cli\u003eEach amp has adjustable level for left and right input channels\u003c\/li\u003e\n\u003cli\u003eEach channel can be switched to the left ear, right ear or both\u003c\/li\u003e\n\u003cli\u003eBalanced inputs have coarse gain controls on rear panel presets\u003c\/li\u003e\n\u003cli\u003ePhase reverse switch\u003c\/li\u003e\n\u003cli\u003eUnbalanced single XLR input mode\u003c\/li\u003e\n\u003cli\u003eXLR audio loop through for daisy chaining multiple amplifiers\u003c\/li\u003e\n\u003cli\u003eHeadphone outputs on 6.35mm jack sockets\u003c\/li\u003e\n\u003cli\u003eBattery powered 2 x PP3\u003c\/li\u003e\n\u003cli\u003eUnit auto powers down when no headphones are inserted in the jacks\u003c\/li\u003e\n\u003cli\u003e18v DC power input\u003c\/li\u003e\n\u003cli\u003eLoop through DC power\u003c\/li\u003e\n\u003cli\u003eLightweight robust aluminium construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBALANCED INPUT IMPEDANCE \u0026gt;50K Ohms \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUNBALANCED STEREO INPUT IMPEDANCE \u0026gt;22K Ohms (On each side) \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eINPUT GAIN RANGE -20dBu to +9dBu \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFREQUENCY RESPONSE: -1dBu @ 40Hz \u0026amp; 20kHz \u003c\/li\u003e\n\u003cli\u003eNOISE: -86dBu (RMS 22-22kHz) @ Min Gain\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNOISE: -80dBu (RMS 22-22kHz) @ Line Up\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNOISE: -62dBu (RMS 22-22kHz) @ Max Gain\u003c\/li\u003e\n\u003cli\u003eDISTORTION @ Line  up into 600 Ohms\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e100 Hz \u0026lt;0.5%\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e1kHz \u0026lt;0.03%\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e10kHz \u0026lt;0.06%\u003c\/li\u003e\n\u003cli\u003eHEADPHONE IMPEDANCE 200 Ohms to 2K Ohms \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHEADPHONE VOLUME POT LEVEL RANGE -?dBu to +10dBu \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMAXIMUM HEADPHONE LEVELS \u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e****WARNING HIGH SOUND LEVELS CAN BE HARMFUL TO YOUR HEARING**** \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e+16dBu into 2K Ohms \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e+16dBu into 600 Ohms \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e+15dBu into 200 Ohms \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHEADPHONE CONNECTORS 6.35mm A \u0026amp; B gauge\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePOWER Internal: 2 x PP3 9 volt battery \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEXTERNAL DC INUT: 18V @ \u0026lt; 29mA \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEXTERNAL DC INPUT \u0026amp; OUTPUT CONNECTORS: 2.5 mm Jack (inner positive) \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBATTERY LIFE \u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBATTERY INDICATOR Steady red LED indicates good battery Flashing red LED indicates low battery \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOVERALL SIZE 40 x 172 x 121 mm (H x W x D) \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUNIT WEIGHT 560 Grams\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Glensound","offers":[{"title":"Default Title","offer_id":45147474001999,"sku":"GS-HA008","price":1074.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9466\/9382\/files\/timthumb_cd746247-f8ce-42a0-9719-a59572f2cbb1.jpg?v=1777296541","url":"https:\/\/shop.musicredone.com\/products\/glensound-gs-ha008-twin-headphone-amplifier","provider":"RedOne Music Canada","version":"1.0","type":"link"}
