HIFIMAN EF400 Desktop Headphone DAC& Amplifier with Himalaya R2R DAC

Huge power and exceptional sound in a slim, sleek chassis The EF400 is the modern desktop DAC/AMP solution with a compact size and adequate price but with sound quality that far exceeds products in size. Experience the valuable power of the R2R-DAC HIMALAYA is a discrete R2R-DAC module (digital-to-analog) based on the FPGA algorithm. Combinations of a low audio frequency range, out-of-band noise, and low power consumption make it the perfect match for high-performance audio equipment. HIMALAYA DAC module supports standard PCM music signal, which is transmitted from the most common IIS audio interface (Integrated Sound Interface) with a maximum resolution of 24 bits Total Balance The four-channel differential structure includes a DAC, buffer and active filter, adding to an unbeatable and fully balanced output that delivers impressive class AB DAC/amplifier performance. The fully differential four-channel amplifier circuit has a maximum output of 10.7 Vrms (THD < 1%) with a resistance equivalent load of 36 Ω. The result: Unsurpassed fully symmetrical performance High gain NOS 4-stage function switch, high gain operating system, low gain operating system, NOS ★ low gain headphone output (front) 6.35mm unbalanced; 3.5mm unbalanced; 4.4mm 4-pin balanced XLR output. ★ Line balanced CANNON output (rear); RCA (single end) ★ USB Type-C input; USB-B Unbalanced 3.5mm and balanced 4.4mm headphone jacks are suitable for controlling high-sensitivity in-ear headphones. IMPORTANT: Use them in low gain mode to avoid excess power that could damage the headset.
