Amplifier Technologies has applied our simple and straightforward design-thinking for a multizone audio experience. The AT7012 and AT7016 amps are designed for high-demand, multi-channel, multi-zone applications. Providing 70 watts per channel through the legendary ATI amplifier input to output stages, ATI distribution amps will fill a home, estate or commercial space with clear and dynamic sound for up to 16 speakers with clean and dynamic sound for up to 8 zones.

The ATI AT7000 distribution power amplifiers are the perfect solution for multi-room sound installations requiring the utmost in flexibility, reliability and powerful sound quality. The ATI AT7012, a 6-Zone, 12-Channel model and the AT7016, an 8-Zone, 16-Channel model incorporate the same legendary sonic design approach as other ATI award winning amplifiers. Continuing the tradition of powerful multi-zone amplifiers, each zone’s 2 channel power amp PCB has its own DC power supply.

The ATI AT7000 Series amplifiers incorporate a hybrid active cooling system design, which includes the addition of ThermalTrak™ power transistors to maintain each amplifier channel’s optimum thermal operating point. Features included for the AT7000 Series are Global Stereo Bus input, ATI Auto-sensing Universal AC Mains Voltage with Soft-Start, 3-24VDC remote trigger turn-on and a Microprocessor Controlled, Optically Isolated Protection Circuit. Both models have a 7.00” (4RU) front panel saving critical cabinet and rack-mounting space. A rack-mounting kit is available separately.

Technical Specifications: 

Zone Level Controls: Switchable input attenuation per zone with five selectable levels: 0, 2, 4, 6 or 8dB via a 4-section zone DIP switch.

Cooling System: Convection and forced air fan cooling using a high aspect ratio heatsink with a shock-mounted microprocessor-controlled computer fan.

Universal AC Voltage & Soft-Start: ATI’s proprietary voltage-sensing power supply automatically selects the proper AC mains voltage, either 120V or 240V.

Remote Power On: Via remote trigger of 3 to 24VDC via a heavy-duty relay.

IEC Power Connector & Circuit Breaker: Internationally approved IEC 60320-C20 20A capable AC connector and 20A magnetic circuit breaker to protect against over-current at the chassis.

Power Supply: 40% more efficient than EI-type Highly efficient silicon-steel toroidal transformer core with separate bi-filar windings for low-noise and crosstalk.

Circuit Boards: Double-sided, FR-4 glass-epoxy computer-grade boards, designed and assembled in-house.

Optically Isolated Protection Circuit: Automatically senses over-current and other performance risks with a full automatic reset.

Speaker Output Connections: Phoenix-type removable terminal blocks support up to 8AWG speaker cable and 32 amps of current.
