TOA A-3512D 120W Digital Mixer Amplifier 2-Zone 5-Input 100V & 4-16 Ohm
The TOA A-3512D is a 120W Class D Mixer Amplifier with 5 inputs, 2-zone speaker selection, emergency and priority paging, phantom power and both 100V line and 4-16 Ohm low-impedance speaker outputs — the compact, lower-power model in the TOA A-3500D series, ideal for smaller background music and paging installations in retail, education, hospitality and commercial environments.
The TOA A-3512D is the 120W model in the TOA A-3500D series of Class D mixer amplifiers — sharing the same comprehensive feature set and versatile input/output configuration as the larger A-3548D, but with a lower power output that makes it the ideal choice for smaller venues and installations where 480W would be excessive. 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.
Flexible 5-Input Configuration
The 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.
2-Zone Speaker Selection & Emergency Output
Two 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.
Class D Efficiency & Reliable Performance
The 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.
