DAC Specifications

Maximum Output Voltage
This is the maximum voltage that the amplifier or preamplifier is able to output.
Output Impedance
This is the amount of impedance that the microphone allows.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Crosstalk is defined as the unwanted transfer of signals across communication channels. The higher this number is, in dB, the better crosstalk rejection the DAC is capable of.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
Digital Inputs
The type of digital inputs the digital-to-analog converter features.
Jitter is a deviation in or displacement of the pulses in a high-frequency digital signal.
Line Level Outputs
The type of analog line level outputs the DAC features.
Sample Rate
Power Requirement
This is the required way to give the unit power. Common power sources are 120V AC (Common house plugs), batteries, or a combination of the two.

Please refer to the description to find out how many are required for the unit to be properly powered.

Don't go getting any bright ideas

Does it work with iPoructs? yup.

Android is hit-n-miss. Since it said it was working with the S4, I gave it a try.

It DID work with my cheap android tablets, but I just could not get it working with a Note 4. Not even after a lot of different tricks/hacks/mods/ROMs..

Rating is for its actual intended use, in which it did work as intended.

I ended up returning it, in my case I'm just going to better off replacing my head unit at this point.

Will this enable my iPhone 5s to be able to connect to my kenwood ddx371? It usually is only able to stream to iPhone 4 because it is analog and my iPhone 5 is digital

Best Answer: Hello Zach,

No, a traditional Lightning to USB is the intended cable. In fact, Kenwood suggests the Kenwood KCA-IP103, which is exactly that. This is for audio playback only. You'll be able to listen to stored music and music apps on your Lightning-connector Apple device through the Kenwood DVD receiver. Video playback is not supported.
