Compact Studio Monitor with Digital and Analog Inputs
The Fostex 6301ND is a rugged, compact active monitor designed for professional mobile, project, and home studios. Equipped with a 4" full-range driver and a 20W Class-D amplifier, it delivers balanced, clear sound across 70 Hz to 15 kHz.

It features both a 1/4" unbalanced analog input and a digital AES/EBU XLR input, plus a digital thru connector to chain multiple units seamlessly. An input selector switch allows you to choose left, right, or both channels per speaker.

The front panel includes a power switch and rotary volume control for quick adjustments. Built-in protection circuitry safeguards against overloads and short circuits. The die-cast aluminum enclosure is durable enough for demanding professional use. Magnetically shielded for safe placement near screens, it also features a multi-voltage power supply and an Auto Standby Mode to reduce power consumption to 0.5W after 25 minutes of inactivity.
