Designed for professional public address, background music and paging applications across retail shops, supermarkets, bars, restaurants, schools, offices, sports facilities and houses of worship, the A-3512D provides a comprehensive all-in-one mixing and amplification solution for installations requiring reliable, flexible and easy-to-manage 2-zone audio from a single compact unit.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFlexible 5-Input Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe A-3512D offers five input channels covering a wide range of source types and connectivity requirements. Inputs 1 and 2 feature selectable MIC\/LINE operation via electronically balanced removable terminal block and 6.3mm phone jack connectors, inputs 3 and 4 provide additional MIC and selectable MIC\/LINE inputs via 6.3mm phone jacks, and input 5 accepts unbalanced stereo line-level signals via RCA connectors for media players and other consumer audio sources. Two phantom power supplies are provided for condenser microphone use, and a dedicated power amplifier input on RCA allows the A-3512D to be driven from an external line-level source when required.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e2-Zone Speaker Selection \u0026amp; Emergency Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTwo independently selectable speaker zones allow different audio to be distributed to different areas of a venue, with zone control inputs and outputs for remote zone switching and integration with external control systems. Both zones support 100V high-impedance line operation for distributed speaker systems, and the direct speaker output additionally supports low-impedance loads from 4 to 16 Ohm for conventional speaker connection. An emergency output, power remote output and zone control outputs provide the integration capability required for life safety and building automation system connectivity in professional commercial installations.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eClass D Efficiency \u0026amp; Reliable Performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe Class D amplifier delivers 120W of output power with a frequency response of 50Hz to 20kHz (±3dB) and a signal-to-noise ratio of 88dB (A-weighted) for clean, clear audio reproduction across both music and speech applications. A distortion figure of less than 1% at rated power ensures consistent, reliable audio quality throughout the operating range. The universal power supply (100–240V AC, 50\/60Hz) enables straightforward installation in any mains environment.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eTOA A-3512D Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e120W Class D Amplifier:\u003c\/strong\u003e Efficient amplification for smaller 100V line and 4-16 Ohm low-impedance speaker systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 Input Channels:\u003c\/strong\u003e 3 x MIC\/LINE selectable, 1 x MIC, 1 x AUX (RCA stereo) for comprehensive source connectivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 Phantom Power Supplies:\u003c\/strong\u003e For condenser microphone use on compatible inputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Zone Speaker Selection:\u003c\/strong\u003e Independent zone control for distributing audio to different areas of a venue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100V Line \u0026amp; 4-16 Ohm Speaker Outputs:\u003c\/strong\u003e Flexible compatibility with both distributed and direct-connect speaker systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmergency Output:\u003c\/strong\u003e For integration with life safety and building emergency systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZone Control Inputs \u0026amp; Outputs:\u003c\/strong\u003e Remote zone switching and external control system integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Remote Output:\u003c\/strong\u003e For controlling connected equipment power sequencing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 x Line Outputs \u0026amp; 1 x Rec Output:\u003c\/strong\u003e For signal distribution and recording connectivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Amplifier Input:\u003c\/strong\u003e Allows external line-level source to drive the amplifier directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Power Supply:\u003c\/strong\u003e 100–240V AC, 50\/60Hz for straightforward installation in any mains environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSame Feature Set as A-3548D:\u003c\/strong\u003e All the functionality of the larger model in a lower-power configuration for smaller installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature -10°C to +40°C:\u003c\/strong\u003e Suitable for a wide range of commercial installation environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdeal for Retail, Education, Hospitality \u0026amp; Houses of Worship:\u003c\/strong\u003e Compact 2-zone mixing and amplification for smaller commercial PA and background music installations.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOA","offers":[{"title":"Default Title","offer_id":57528390091125,"sku":"A-3512D","price":468.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/TOAA3512D_TOA_A-3512D_Image_1.webp?v=1787843260","url":"https:\/\/www.audiovolt.co.uk\/products\/toa-a-3512d-120w-digital-mixer-amplifier","provider":"Audio Volt ","version":"1.0","type":"link"}
