FAQs

Do the USB and SPDIF coaxial outputs both operate at the same time?

Operating systems

General Operation Technical

ZEN Stream

No. If the USB output is used the coaxial output switches off. If no USB DAC is plugged in, the coaxial output switches on. The outputs can also be managed…

Do the ZEN Stream and computer need to be on the same Wi-Fi network?

Operating systems

Operation

ZEN Stream

Yes. Alternatively, use the Wi-Fi hotspot. Please see the FAQ ‘Do I need a Wi-Fi network router?‘

Do USB cables degrade the signal?

Accessories

General

Gemini3.0 Mercury3.0

All cables can only degrade. So with cables, you get degradation for impedance mismatch and signal degradation. The closer the cable adheres to the impedance spec (90 Ohm) the less…

Do you manufacture this cable in different lengths?

Does a Renderer & Decoder DAC yield the same end result?

Operating systems

MQA (Master quality audio)

(From MQA) – Whether the decoding and rendering takes place in the same device, or the process is split between a software application and a rendering device, the result will…

Does Bluetooth V5.0 offer benefits over earlier versions?

DAC

Bluetooth

xDSD

Yes and no. For audio streams, Bluetooth V5.0 does not really offer material differences to 2.1 (neither do 3.0, 3.1, 4.2 etc). Almost all Bluetooth 5.0 improvements over 4.2 focus…

Does it affect signal levels?

Accessories

General

iPurifier3

The iPurifier 3 does not affect audio signal levels at all (it cannot).

Does it come with a power supply?

Power

ZEN Air Blue ZEN Air DAC

We wanted to create a high quality DAC for customers on a budget, so a power supply is not included, but you can power the device via the USB port.…

Does it contain bi-directional filtering?

Accessories

Operation

DC iPurifier2

Yes, it works bi-directional and will filter the power in these directions.

Does it contain over-current and over-voltage protection?

Accessories

Operation

DC iPurifier2

Yes, it does contain over-current and over-voltage protection based on thermal fuses, if this protection circuitry is engaged the unit may become very hot and will not produce much output…

Does it draw power?

Accessories

iPurifier3

Yes, the iSilencer draws some extra power as it has active noise cancellation, around 22mA (exact amount depends on power voltage). Further question: Is it possible to use with a…

Does it feature any USB improving technology by iFi audio?

NEO iDSD

Just like any other iFi audio DAC, our NEO iDSD’s USB input also features a number of our proprietary measures to sound the best it possibly can.

Does it handle all types of audio formats?

nano iUSB3.0

Yes the iUSB3.0 handles audio and power according to USB Audio Class 2.0 & 3.0. Therefore, it passes all audio types (DSD, DXD, PCM) and files through just fine.

Does it have a flat EQ (no EQ)?

Analogue

General

micro iPhono2

No, flat EQ. We find that software EQ loses resolution at a frightening rate. As there is no digital “boost” beyond 0 dBFS, the digital domain EQ attenuates the midrange…

Does it have a headphone amplifier?

DAC

Operation

Pro iDSD Pro iDSD Signature

There is no “headphone amplifier” in the Pro iDSD / Pro iDSD Signature. Just a gain stage/line driver that is sufficiently powerful to drive many headphones directly, however, doing so…

Does it have a sleep mode if no signal is present?

DAC

Operation

nano iDSD Black Label

No, the nano iDSD Black Label does not have a sleep mode.

Does it have AVRCP?

DAC

Bluetooth

xDSD

No AVRCP confirmed.

Does it have polarity?

Accessories

General

iPower

Do the pins have polarity, and if so, does it matter how it is plugged into the outlet? There is no ground pin, so you can pretty much flip it…

Does it invert polarity?

Analogue

Operation

micro iPhono2

No, it does not invert polarity in MC or MM.

Does it keep the shield effective against EMI/RFI as ground is disconnected?

Accessories

Operation

iDefender3.0

Yes, ground is disconnected “softly”, that is for RF frequencies the grounds remain connected, but for low frequencies (mains frequency and harmonics as well as 1/8kHz USB packet noise) that…

Does it make any difference whether it’s powered via USB or externally?

ZEN DAC Signature V2

Although both options are perfectly fine, in order to maximize sound performance, we advise to power the ZEN DAC Signature V2 via our iPower X power supply.

Does it make any difference whether it’s powered via USB or externally?

DAC

ZEN DAC V2

Although both options are perfectly fine, in order to maximize sound performance, we advise powering the ZEN DAC V2 with our iPowerX power supply.
