Huge power and exceptional sound in a slim and smart chassis. The EF400 is a modern desktop DAC/AMP solution that delivers sound quality far exceeding its compact size and affordable price.

Experience the valuable power of an R2R-DAC. HIMALAYA is a discrete R2R-DAC module (digital-to-analog) based on an FPGA algorithm. The combination of low audio frequency range, out-of-band noise, and low power consumption makes it ideal for high-performance audio equipment. The HIMALAYA DAC module supports standard PCM music signals up to 24-bit resolution from the most common IIS audio interface (Integrated Sound Interface).

Total Balance: The 4-channel differential structure includes a DAC, buffer, and active filter, adding an unparalleled fully balanced output, delivering impressive Class AB DAC/amp performance. The maximum output of the fully differential 4-channel amplifier circuit is 10.7Vrms (THD <1%) with a resistive equivalent load of 36Ω. The result is outstanding 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-ended) ★ USB Type-C input, USB-B.

The unbalanced 3.5mm and balanced 4.4mm headphone jacks are suitable for controlling high-sensitivity in-ear headphones. Important: Use in low gain mode to avoid excessive power that could damage the headset.
