DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable.While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.

Pair with Laptop via USB
A majority of people use a laptop as the primary source device to listen to music or watch movies. Since the laptop is an essential part of the audio chain there are headphones and devices designed to work a laptop or computer system flawlessly. With the availability of USB connectivity, it becomes easier to pair various devices like an Amp, DAC or even headphones without worrying about drivers or any additional piece of software.

Volume Controls
If your DAC & Amps include volume controls or volume rockers, you can easily change the volume with a button press or volume knob turn.
DAC & Amps that have volume controls make its operation incredibly simple; turn up the volume on your smartphone or your source devices and then change the volume on DAC & Amps to the desired level.
This design feature allows you to have complete control over the desired volume according to your listening preferences.

DESCRIPTION
BALANCED DAC & HEADPHONE AMP FEATURING HIMALAYA R2R DAC
HiFiMAN proudly presents the all-new EF400, a Balanced DAC & Headphone Amp that combines the newly developed technology, including the company's superior HIMALAYA R2R DAC architecture. The EF400 is a modern desktop DAC and amplifier delivering Next-Level Sonic Performance. With the high-level technology developed by HiFiMAN, it comes as no surprise that the HIMALAYA R2R DAC had been a recipient of the 2022 lifestyle VGP Gold Technology Award held in Japan.



MASSIVE POWER OUTPUT OF 4.4 W PER CHANNEL DELIVERING SUPERIOR SOUND
The HiFiMAN EF400 is a modern desktop DAC & Amp solution. Providing Ultra-high efficiency and low power consumption at maximum stability of 4.4W per channel balanced output. HiFiMAN EF400 is embedded with oxygen-free copper wire wound toroidal transformer, HIMALAYA R2R DAC module, 30000uf large capacitors, and high current amplifier circuit to deliver optimum and stable power outputs.



EXPERIENCE THE PERFORMANCE OF THE R2R DAC, A RARE DELIGHT MADE POSSIBLE BY HIFIMAN
The HiFiMAN EF400 DAC & Amp architecture is designed with a discrete HIMALAYA R2R DAC module, based on an FPGA algorithm. It's an excellent match for high-performance audio equipment because of its low audio frequency range, minimal out-of-band noise, and low energy consumption. With a maximum resolution of 24 bits, the HIMALAYA DAC module supports the standard PCM music signal provided by the most common IIS (Integrated Interface of Sound) audio interface. A DAC, buffer, and active filter result in an unequaled balanced output for outstanding performance from a Class AB DAC/amplifier setup. On a 36 Ohms equivalent load, the four-channel differential amplifier circuit produces a maximum output of 10.7 Vrms (THD1%). The result is a perfectly balanced output that is unrivaled.



OPTIMAL BUILD AND SUPREME CONNECTIVITY OPTIONS WITH 4-LEVEL GAIN FUNCTION SWITCH
EF400 has a polished and stylish chassis which gives it a robust feel and premium look. The compact physical dimensions of the EF400 contradict its substantial output. Measuring 246.5mm(L)×228mm(W)×61mm(H), the EF400 requires the bare minimum of desktop or rack space. The front panel includes two unbalanced outputs - 6.35mm, and 3.5mm, and two balanced outputs 4.4mm, XLR four-pin. In addition, EF400 also offers a four-level gain function switch with High Gain NOS, High Gain OS, Low Gain OS, Low Gain NOS Headphone Out, and volume control. The rear input panel includes jacks for USB-B and USB-C source connectors, dual (L/R) XLR three-pin fully balanced line outputs, and is a rarity in products.
