Fostex 6301DT 4-inch Powered Studio Monitor User Manual

Introduction

The Fostex 6301DT is a compact and versatile 4-inch powered studio monitor, designed for broadcast, production facilities, mobile setups, project studios, and home recording environments.

Volume Adjustment

Rotate the Volume knob on the front panel clockwise to increase the output level and counter-clockwise to decrease it. Start with a low volume setting and gradually increase it to a comfortable listening level.

Input Selection

  • Analog: Selects the 1/4" TS analog input.
  • Dante Channel 1: Monitors the first Dante audio channel.
  • Dante Channel 2: Monitors the second Dante audio channel.
  • Dante Channel 1+2 (Mixed): Monitors a mix of both Dante channels.

Dante Network Configuration

For Dante network operation, you will need to use Audinate's Dante Controller software on a computer connected to the same Dante network. This software allows you to route audio signals to the Fostex 6301DT and configure its network settings. The 6301DT supports sampling frequencies of 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz.
