The Symphony I/O Mk II Thunderbolt redefines professional audio interface performance with its groundbreaking 1.35ms round-trip latency when paired with Logic Pro X. Built around Apogee’s proprietary Thunderbolt driver and revolutionary Direct Memory Access (DMA) engine, this interface processes enormous amounts of data at incredible speeds whilst making minimal demands on your Mac’s CPU. The custom hardware logic chip handles data reading and writing directly to Mac memory, independent of the CPU, resulting in the highest resolution signal possible reaching the DAC stage. For producers who prefer direct monitoring, the Symphony I/O Mk II Thunderbolt offers optional hardware monitoring through Symphony Control Software with just 0.6ms latency. This flexibility means you no longer need to compromise between processing power and speed, even when your sessions demand higher buffer settings for intensive DSP work. Symphony Control software provides comprehensive access to all interface functions on macOS, including gain level management for preamp modules, routing control, output level adjustment, calibration settings, and multiple mixer configurations. The new Monitor Workflows feature allows seamless setup and operation of immersive audio systems including Dolby Atmos and Sony 360 Reality Audio, with control over up to 32 speaker outputs, plus compatibility with the new Apogee Control hardware remote.
