Franklin Audio A4012 Multi-Zone 12 Channel AmplifierThe Franklin Audio A4012 features a Class-AB output circuit that delivers superior audiophile sound quality and steady performance. Each of your installation's zones can benefit from the A4012's clean audio reproduction and excellent functionality. The A4012 can be stacked with other audio components and includes removable ears for mounting in standard audio racks (2RU).
Two common or BUS inputs feed audio signals from standard line-level audio sources to any or all channels. Each of the twelve channels has its own dedicated input and independent level adjustment to provide additional flexibility. By simply flipping a single switch, two channels can be bridged to increase the total power output for that zone. This is helpful when extra power is needed in certain areas.
Specifications: • Rated power output per channel: 40 watts into 8 ohms, 60 watts into 4 ohms (0.09% THD) • Bridged output: 80 watts into 8 ohms (0.30% THD) • Signal to noise ratio: 105 dB A-weighted • Input impedance: 18K ohms • Input sensitivity: 380 mV • Frequency response: 5 Hz - 72 kHz • Channel crosstalk: 80 dB • Dimensions: 16.7" W x 4" H x 14.25" D (tabletop configuration) • Power requirements: 115/230 VAC, 60/50 Hz • Stand-by power rating: 115V, 0.264W • Weight: 38 lbs.
The A4012's manual, automatic on/off, or triggered 12V input turn-on modes facilitate easy integration into automatic systems. For quick and easy troubleshooting of the system, each pair of channels or zones has a bi-color LED to indicate its operational status.
