Presonus Quantum 4848

Features

General Features

  • 48×48 ultra-low-latency 24-bit 192 kHz Thunderbolt ™ 2 audio interface
  • 32 line-level inputs and outputs via rear-panel DB25 connectors
  • Dual ADAT inputs and outputs for 16 channels of digital I/O at base sample rates.
  • Stack up to four Quantum 4848 interfaces via Thunderbolt for 192×192 simultaneous inputs and outputs
  • Stack any combination of four Quantum and Quantum 4848 interfaces (or add one Quantum 2626 interface) via Thunderbolt to create a custom system

Integrated Software

  • Tight integration with included Studio One® Professional DAW software (macOS®/Windows®) for multitrack music production and mastering
  • Native Studio One Pipeline XT plug-in provides easy integration of analog processors in a digital recording environment
  • Select the Channel Profile modes, monitor levels, switch the front panel level meters (input/output), and more with free UC Surface touch-control software (macOS/Windows/iPad®/Android ™ *)
  • Wireless control of Studio One Professional using free Studio One Remote for iPad/Android tablet
  • Studio Magic Software Suite included
  • Ableton® Live Lite included
  • Compatible with most recording software for macOS and Windows

* Note: there is no stand-alone support for iOS and Android. You can control Quantum-series interfaces from these devices, but the interface must be connected to a computer that is on the same network as the tablet.
