Apollo 8p. Next-Generation Conversion with Eight Onboard Preamps.Apollo 8p is a dramatic update to one of the world’s most popular professional audio interfaces, delivering enhanced sound with the tone, feel, and flow of analog recording. This 16 x 20
Thunderbolt 2 interface features eight onboard Unison™ mic preamps — perfect for mobile rigs and tracking full bands. Built on genuine UA analog design and next-generation A/D and D/A conversion, Apollo 8p also features powerful UAD-2 QUAD Core processing, letting you run UAD Powered Plug-Ins in real time. With sound that surpasses anything in its class, Apollo 8p rivals modular converters costing twice the price, in a sleek new package.Features & Specs.
Audio Interface
Sample rates up to 192 kHz at 24-bit word length
16 x 20 simultaneous input/output channels:
Eight channels of analog-to-digital conversion via mic, line, or high-impedance inputs
