Thank you for purchasing the DAC from the ZEN series. The DAC is a balanced USB-audio dac amplifier.
Please connect the enclosed 5V power supply. If the computer audio source is able to supply the 5V, the DAC can also be power by USB.
1. PowerMatch (high/low)
The PowerMatch setting should be on low for IEMs and on high for on/over headphones.
Warning: before changing the PowerMatch setting, always turn the volume down so as not to damage your hearing or your equipment. AMR/iFi audio is not responsible for any hearing or equipment damage from misuse.
2. TrueBass (high/low)
IEMs usually sound better with TrueBass set high. They lack bass due to their small driver size. Adjust to suit your personal preference.
3. Volume control
The analogue volume control in the ZEN DAC is superior to any digital volume control. It can be used to control the headphone volume or the pre-amplifier volume (when set to 'Variable'). If the output at the rear is set to 'Fixed', then the volume control is bypassed.
4. Audio Format LED (kHz)
The LED colour scheme indicates the audio format and sampling frequency received by the ZEN DAC from the music source.

5. 6.3mm output
For the connection of 6.3mm single-ended headphones.
6. Balanced 4.4mm analogue output
For the connection of 4.4mm balanced headphones.
Tip: As the ZEN DAC is balanced, we recommend the 4.4mm output.

7. Balanced 4.4mm analogue output
This is an analogue output via 4.4mm > XLR or similarly balanced interconnects. You could use this for a active speaker or amplifier.
Tip: As the ZEN DAC is balanced, this is the recommended output.
8. Variable/Fixed switch
When the rear UnBAL/BAL analogue outputs are used, this switch will select whether or not the ZEN DAC analogue volume control is used.
9. RCA analogue output
This is an analogue output.
10. USB-audio input
This is to connect the computer audio source.
11. DC 5V power
The enclosed 5V power supply here is connected here.
Tip: The ZEN DAC is powered by 5 volts. It is possible to upgrade the power supply by using a super-low noise supply such as the iFi iPower or iPower X.
