Apollo x8 with UAD Analog Classics Pro
Choose options
Apollo x8 with UAD Analog Classics Pro — an 18x24 rackmount Thunderbolt audio interface with four Unison preamps, eight line inputs, and a UAD-2 HEXA Core processor, in the Analog Classics Pro configuration that includes over 80 UAD plugins: preamps, compressors, EQs, instruments, and effects.
Gen 2 Elite-Class AD/DA conversion reaches 130dB of dynamic range with THD at -127dB, using dual-crystal clocking to keep jitter low at every sample rate. Four Unison inputs plus two front-panel Hi-Z inputs let you record a full rhythm section or vocal group at once, each voice through a different preamp emulation — Neve, API, Manley, or Avalon.
The full Pro library for a permanent outboard setup
The Pro edition extends the standard Analog Classics bundle with reverbs from Capitol Chambers and Sound City Studios, the EL8 Distressor compressor, and instruments and synths. With eight additional 1/4" line inputs, that means a studio with a substantial outboard rig — compressors, tube EQs, hardware synths — gets the full plugin library at mixdown without buying additional bundles.
Post-production and spatial mixing in one unit
Eight line outputs configurable as ALT or a full surround system up to 7.1 with bass management let you mix a film soundtrack or immersive content directly from the Apollo x8, without an additional multichannel processor. The HEXA Core processor handles UAD plugins independent of the DAW's buffer, keeping latency low even with a large number of simultaneous channels.
