Unlike ASIO, which often struggles with multiple hardware interfaces, Mac’s Core Audio allows you to combine the DN-HC4500 with other sound cards into a single "Aggregate Device" via Audio MIDI Setup . Optimization: How to Get "Better" Performance
Set this to "Auto" or manually adjust the buffer size to 128 or 256 samples for a balance of speed and stability. 3. Hardware Maintenance DN-HC4500 & OSX Compatibility - VirtualDJ denon+dn+hc4500+asio+drivers+for+mac+better
Core Audio is built into the macOS kernel, allowing it to bypass unnecessary software layers to achieve stable, low-latency performance similar to or better than ASIO on Windows. Unlike ASIO, which often struggles with multiple hardware
On Windows, ASIO (Audio Stream Input/Output) is the gold standard for low-latency audio. On macOS, however, Apple uses , which provides low-latency performance natively without needing the third-party ASIO wrappers that Windows requires. Why Core Audio is "Better" than ASIO for Mac Why Core Audio is "Better" than ASIO for
Set Inputs to "None," Outputs to "External Mixer," and Sound Card to "4-Card Out (DN-HC4500)".
