Home Theater (10)

Please download the latest firmware for HD-AVP and HD-AVA.

  1. Go to OSD setup.
  2. Select Setup tab, then Input Config and then Input setup.
  3. Go to Tuner setup.
  4. Choose your desire frequency station you wish to store as preset.  Once the frequency is selected, go to Memory option: “Choose your desired station. 50 preset stations”

Due to the XLR shield and ground pin specification (see https://en.wikipedia.org/wiki/XLR_connector), some manufacturers implement it differently from others, therefore there could be humming noise if a non NuPrime product is connected to MCH-K38 using XLR cables.nnXLR Hum Eliminator products from http://www.ebtechaudio.com/hedes.html can be used to completely remove the noise and improve performance.

If you are using a Pronto IR remote control, replace “0x” in the above code to “20bf”.  If still does not work, replace 0x with FD04.

Sub output is available for all selections.

These are all marketing descriptions.nnBass management is the LFE in the audio setting (OSD setting > Setup > Speaker Setup > LFE Level)nn”Increasing the performance of single/double post positioning devices” and “comprehensive cross-over design” means there are variety of settings you could configure the unit to suit your system, such as speaker range/position, speaker size, speaker level, etc.

These are manufacturer preset values that have no meaning to end users. It was part of development setup that should have been removed. This setup will be removed in future firmware update. Please ignore them.

Playback from hard disk or DLNA (LAN) can only support up to 1080P resolution. Playback from HDMI support HDMI 1.4 4K but not HDMI 2.0 4K. The HDMI 1.4 specification supports 4K formats: 3840 pixels wide by 2160 pixels high @ 24Hz | 25Hz | 30Hz 4096 pixels wide by 2160 pixels high @ 24Hz

Pure Direct and Pure Audio modes are part of the multi-channel mode and utilize the high quality multi-channel DAC. USB Audio goes through a separate high performance stereo DAC board.

Pure Audio is a 2-channel Stereo mode where multi-channel inputs from the source are converted to 2 channel audio. Pure Direct is a pass-through (from the source device such as BluRay player) mode without any EQ effect.

Don’t confuse Pure Audio or Pure Direct with USB Audio input. If you have a computer connected to HD-AVP through USB Audio, by selecting the USB Audio as input source you will be utilising the high-end stereo DAC (this USB Audio DAC has the same performance as NuPrime DAC-10) instead of the multi-channel DAC for surround sound decoding.

The L&R outputs from 7.1 outputs come from USB DAC outputs or AVP outputs. The USB L&R outputs come only from the USB DAC.  That means if you are using USB Audio as the input, there are two sets of outputs: L&R outputs from 7.1 outputs and USB L&R outputs. This allow you to setup a separate high-end stereo system in another room. Therefore, if you select USB Input as the source, then the USB DAC outputs go to 7.1 L&R RCA and XLR and USB L&R outputs.

HD-AVP includes the same high performance USB DAC implementation as DAC-10, but DAC-10 consist of a better preamp design using switch resistor technique. DAC-10 also includes other digital inputs that go through the same DAC.

In the HD-AVP, only the USB input goes through the stereo DAC for pure 2-channel audio and the other digital inputs are decoded by the multi-channel DAC within the AV processor circuit. In summary, the HD-AVP has a USB DAC that is close to the DAC-10 performance, but offer many additional media server and AV processing features.

Overall, HD-AVP offers tremendous value by combining high quality AVP and 2-channel stereo in a single chassis.
