  • Page 3 INTRODUCTION The USB PRE IV is a high quality, 4-IN / 4-OUT digital recording interface intended for home studio and mobile recording applications. It provides up to 4 mic inputs or two high impedance instrument and two line inputs. Equipped with high quality digital converters, the USB PRE IV offers up to 32-bit /192kHz performance.
  • Page 4 Key Features Include • Four High-Quality 32-bit A to D and D to A Converters • Sample rates from 44.1k to 192kHz • Low latency ASIO and WDM driver • Transformer isolated outputs • Low noise mic preamps • High Z instrument inputs •...
  • Page 5 DRIVERS ART provides a low latency ASIO driver, which you need to download from our website to use the unit with Windows. Ensure your DAW application, such as Cubase LE, supports ASIO I/O to take advantage of this driver and its control panel.
  • Page 6 CONNECTIONS Left and Right “Combo” jacks on the front allow for either XLR or ¼-inch TRS input connections. The 1/4-inch Input connections are used for instrument or line level balanced or unbalanced signals. The high fixed input impedance works well with guitar and other passive instrument pickups.
  • Page 7 +48V Switch: Phantom power is used to power conden- ser microphones. The +48 Volt phantom power (when enabled) is supplied to pins 2 and 3 and pin 1 acts as the ground return. Do not lift pin 1 when using phantom pow- INPUTS: These potentiometers independently vary the input gain for the Left and Right Channels 1 thru 4.

Adjust levels to get a consistently green ring with occasional flashes of red. The red ring indicates 2dB below digital clipping and should light on musical peaks only.
  • Page 11: Headphone Setup

    Headphone Setup The USB Pre IV routes the Headphone (OUT3/4) signal on an independent stereo path from the Main Outputs (OUT1/2). This gives the user the flexibility of creating unique Main and Headphone monitor mixes in their DAW of choice. For listening to system sounds, user must select between the Main Outputs and Headphone output as follows.
