Apogee Electronics Symphony I/O Chassis with 16x16 Analog I/O + 8 Mic PreAmp Module

What is Symphony I/O
Apogee Symphony I/O is a modular multi-channel audio interface featuring premium AD/DA conversion and world-class microphone preamps. Designed to deliver professional sound quality for audio recording, mixing and mastering on a Mac, Symphony I/O is the ultimate music production centerpiece for any modern studio. Connect Symphony I/O to any Mac based Thunderbolt, Pro Tools HD or USB audio workstation.

Legendary Sound Quality
Symphony I/O is the culmination of 25 years of Apogee's award-winning design experience. Using the most advanced components available, Apogee engineers created an extremely efficient circuit and power design resulting in a significant improvement in audio clarity and transparency over any previous Apogee product.

Input and Output Flexibility
There is a Symphony I/O solution everyone; the home studio, project studio, commercial recording studio and scoring stage. Choose from five base configurations, 2x6, 8x8, 16x16, 8x8 with 8 mic preamps or 16x16 with 8 mic preamps and easily expand as your studio grows. With two module slots and the capacity for up to 32 inputs and outputs of A/D & D/A conversion per unit, Symphony I/O offers the best per-channel value of any interface in its category.

ESS Sabre32 DAC Technology
ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequalled dynamic range, ultra low distortion and unmatched audio clarity free from input jitter. While ESS Sabre32 DAC has been widely recognized and employed in the audiophile community as the next step in converter technology, Apogee is one of the first pro audio manufacturers to employ this DAC in an interface designed for audio and video professionals. ESS Sabre32 DAC technology, as employed in Duet 2, Duet for iPad & Mac, Quartet and Symphony I/O, is one ingredient in the Apogee Engineering Difference. The benefits of the ESS Sabre32 DAC include:

32-bit DAC Architecture - Compared to older 24-bit technology, the Sabre32 DAC's 32-bit filter processing results in significantly lower noise and distortion, for a pure listening experience free from artifacts. 32-bit digital attenuation ensures that sonic purity is maintained at any listening level.
Time Domain Jitter Elimination removes clock inconsistencies from the incoming digital data, so the converted analog output preserves the clarity and soundstage detail of the original recording.

I/O Module

The Magic is in the Modules
The I/O Modules are the sound and soul of Symphony I/O and represent 25 years of Apogee R&D and design excellence. These powerful Modules deliver Apogee's core competency, superior sounding digital audio recording.
