The rear panel provides access to the two I/O Module slots that are capable of a combined thirty-two channels of input and output, while the two Thunderbolt / USB-C connectors ensure compatibility with modern Windows and Mac computers. Also included are wordclock I/O connectors and termination, an option-card slot, and a quiet digitally controlled fan to keep everything running cool. The optional five I/O Modules allow the user to choose from standard configurations, or customize the following-channel count, analog to digital input, digital to analog output, microphone preamps (requires an analog card), and digital I/O.

The Symphony I/O Mk II features a single ultrahigh-fidelity DAC and headphone amplifier with Apogee's Constant Current Drive technology, which was first introduced in the Apogee Groove. The headphone amplifier dynamically compensates for the nonlinearities of any connected headphones, providing massive power while maintaining extremely low distortion and linear frequency response.

Designed for recording and tracking, the Audeze LCD-S20 are a pair of closed-back planar headphones that offer superior sound quality and noise isolation. The LCD-20 features SLAM, a patent-pending technology that ensures an extended, dynamic bass with lifelike punch that stays clean even at high volumes. Acoustically dampened earcups block out external noise and prevent microphone bleed.

The LCD-S20 utilize powerful 90mm neodymium drivers and patented Audeze tech like a Fluxor magnetic array, Fazor phase management, and an Ultra-Thin Uniforce diaphragm. The cloth-covered gel-filled earpads are not only comfortable for long listening sessions, but provide the perfect seal to ensure the optimum bass response. The LCD-S20 include one braided 3.5mm audio cable and one 1/4" to 3.5mm plug adapter.
