Each speaker output has a stereo input source that can be selected between the internal audio player or three external stereo line inputs and even a digital optical input for AV applications. The inbuilt media player section offers playback of mp3 audio tracks from USB drive or microSD card and also has a B\/T wireless receiver and FM radio tuner. Each speaker output zone has a wide ranging power capability from background music up to higher sound pressure levels, with Bass, Treble and Master Volume controls for independent sound management. Two microphone inputs have individual level controls and can be set to override the stereo line input for voice announcements. Emergency muting can be actuated from an alarm panel via the 24V EMG MUTE contacts on the rear panel. The A-series commercial amplifiers offer sophisticated functionality and power in a convenient 2U rack package with a comprehensive and accessible control surface. Each variant of this range is appointed to meet the needs of different sized installations with flexible setup options to serve various system topologies.\u003ch4\u003eSpecifications\u003c\/h4\u003e2-band EQ per output zone\u003cbr\u003eEach stereo output zone can be summed as dual mono\u003cbr\u003eInternal audio player with USB\/microSD playback\u003cbr\u003eS\/PDIF optical input\u003cbr\u003eVoice override for mic inputs\u003cbr\u003eBluetooth connectivity\u003cbr\u003eFM radio tuner with external aerial connection\u003cbr\u003e24V emergency mute contacts\u003cbr\u003ePower supply:230Vac, 50Hz (IEC)\u003cbr\u003eAmplifier : construction:Class D\u003cbr\u003eFrequency response:20Hz - 20kHz ±0.5dB\u003cbr\u003eMicrophone inputs:2 x 6.3mm jack (mono) front or rear panel\u003cbr\u003eLine inputs:Line 1 (L+R RCA), Line 2 (L+R RCA)\u003cbr\u003eDigital audio input:TOSLink optical (S\/PDIF)\u003cbr\u003eInput sensitivity : line:0.775Vrms\u003cbr\u003eInput sensitivity : aux:0.480Vrms\u003cbr\u003eAuxiliary input:3.5mm stereo jack\u003cbr\u003eInput impedance:10k Ohms\u003cbr\u003eAudio source:USB\/microSD mp3 playback, FM tuner, B\/T receiver\u003cbr\u003eB\/T wireless version:2.3\u003cbr\u003eInput controls:Aux, Media, Line1, Line2, Mic1, Mic2, Talkover\u003cbr\u003eOutput controls:Mode, Stereo\/Mono, Treble, Bass, Channel Volumes\u003cbr\u003eAntenna connection:F type (FM tuner)\u003cbr\u003eDynamic range:92dB\u003cbr\u003eTHD +N:\u0026lt;0.1%\u003cbr\u003eProtection:Thermal, over-current, over-voltage, short-circuit\u003cbr\u003eEmergency control:24V mute terminals\u003cbr\u003eDimensions:482 x 300 x 88mm","brand":"Adastra","offers":[{"title":"Default Title","offer_id":53418866606419,"sku":"953.483UK","price":499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/8667\/5539\/files\/953483UK_CO1.jpg?v=1775567186","url":"https:\/\/www.venutec.co.uk\/products\/adastra-a8300-mixeramp-8-x-300w-953-483uk","provider":"Venutec","version":"1.0","type":"link"}
