The Fostex 6301N series is the redesigned version of the popular 6301 series, which has been a standard active monitor speaker in broadcast and production facilities since 1982.
The 6301N series maintains the same form factor and adds several improvements in performance and features.
Key Features of the Fostex 6301N Series
- 20W D-Class Power Amplifier – The speakers are equipped with a 20W D-class power amplifier, which provides a higher output level and consumes less power compared to the previous models. The D-class amplifier design eliminates the need for a heat sink, making the speakers more compact and efficient.
- Dedicated 4-inch Full Range Driver – The 6301N series features a dedicated 4-inch full range driver that ensures clear and accurate audio reproduction. The driver unit has been optimized for enhanced performance and delivers balanced sound across the frequency range.
- Flat Panel Design – The speakers have a flat panel design, which helps prevent accidental power-off or level changes. This design feature ensures stability during operation and minimizes the risk of interruptions or adjustments.
- Auto Stand-by Mode – The 6301N series includes an energy-saving “auto stand-by” mode that complies with the ErP directive. When there is no audio signal for a certain period, the speakers automatically enter stand-by mode, reducing power consumption. This feature is both environmentally friendly and helps prolong the speaker’s lifespan.
- Multiple Connectivity Options – All models in the 6301N series come with a 1/4″ TS Phone (unbalanced) input connector. Additionally, the 6301ND model offers an XLR-3-31 input connector, compliant with the IEC 60958 AES/EBU digital audio standard. The 6301ND model also has a higher input impedance of 110 ohms for digital AES/EBU connections.
