area should not be touched, especially the top panel and areas surrounding the
“Hot Surface” symbol.
Important
-
When installing and placing the product, please fully consider its heat dissipation.
-
Power voltage may vary in different countries and areas. Before connecting this product to a power source for the first time, please make sure the rated voltage (for instance, alternating current AC 230V S0Hz or alternating current AC 115V 60Hz) on the panel corresponds to local voltage. If not, the power supply should be turned off and the power cable disconnected before adjusting the voltage selector to make sure the power supply corresponds to the local voltage before reconnecting. The value displayed on the voltage switch is the current voltage.
-
Firmly grasp the plug when the power cable is being unplugged. Do not pull the cable to unplug.
-

Key Highlights
EF1000DAC is a Balanced Headphone Amplifier and DAC which is stable in
operation, highly efficient, and is, ideal for a variety of applications.
The EF1000DAC features the next generation of HIFIMAN’ s R2R DAC, HYMALAYA
PRO. Resolution, sonic output, and the overall listening experience surpasses
the more common PCM1704 to set a new standard in personal and desktop audio.
- High-speed FPGA built-in algorithm achieves excellent anti-aliasing performance with low noise output that does not affect the clarity and soundstage of the overall listening experience.
- The optimized sampling algorithm delivers the same timbre as NOS (non-oversampling) technologies for sound that is smooth and natural.
- Resistors used in the 0.01% precision, low power consumption design support control of temperature drift, ensuring THD (total harmonic distortion) remains ultra-low and inaudible.
- Four HYMALAYA PRO DAC modules are embedded for a fully balanced design for two channel crosstalk that is consistently lower than PCM1704.
Qualcomm QCC5124 System-on-Chip (So() is embedded for low power consumption
design.
Support Bluetooth 5.0, with LDAC and aptX HD technology specially designed for
high resolution wireless audio, it can bring excellent sound quality
performance.
The sound quality is maximized by incorporating high-quality components and
precise processing technology.
Introduction
Front Panel Layout
Important
- Push “INPUT” Selector Switch on on the front panel to select the audio source: BT, USB, OPTICAL, COAXIAL, or RCA. The corresponding white LED light of the selected input mode will be illuminated. The light flashes when the BT Bluetooth input is not paired, and remains steady after successfully pairing with the source.
- Headphone plugs: 6.35mm (1/4″) and 4-pin XLR. When the headphone is connected to the EF1000DAC, the auto-locking mechanism will secure the headphone plug in place. To disconnect the headphone, press the release button and gently pull the plug at the same time.
- For standby mode, when the EF1000DAC is powered up, press and hold the standby button for 3-5 seconds to start up; press the standby button for 3-5 seconds again, the EF1000DAC is then off.
Real Panel Layout
Important
- Power voltage may vary in different countries and areas. Before connecting this product to a power source for the first time, please make sure the rated voltage (for instance, alternating current AC 230V 50Hz or alternating current AC 11 SV 60Hz) on the panel corresponds to local voltage. If not, the power supply should be turned off and the power cable disconnected before adjusting the voltage selector to make sure the power supply corresponds to the local voltage before reconnecting. The value displayed on the voltage switch is the current voltage.
- If the power cannot be connected, please contact HI Fl MAN customer service or an authorized HI Fl MAN dealer. If it is confirmed that it is a fuse, the provided back-up fuse should be used.
