NuForce AVP-18 Additional Instructions Download Page 9

My HDMI TV (HDMI 1.4 and above) supports Audio Return (ARC), how do I play back the TV audio using the AVP-18?

Select 

input ‘TV ARC.' The AVP-18 will switch to the HDMI audio coming from the TV. Please note that not all HDMI TVs provide the ARC 

feature.

Why do I hear signals coming from the rear surround speakers when playing back a DTS-HDMA 5.1CH audio signal?

The Surround signals are repeated in the Rear Surround channels as required by the DTS format.

Does the AVP-18 support DSD (SACD player as source) over HDMI?

The AVP-18 does not support DSD over HDMI. BD Players compatible with SACDs can often be set to output PCM format at 88.2kHz to the 
AVP-18 automatically.

What is “Direct" and does EQ have any effect with this setting?

“Direct” refers to a ‘purist’ form of decoding, such that the AVP-18 turns off all DSP enhancements like room correction and EQ. It’s 
recommended for dedicated 2-channel audio, but not for Movie sound tracks (except perhaps, acoustic music videos, etc.).

Could the video signal be compromised by inserting the AVP-18 into the signal path?

No

, it shouldn’t. The AVP-18 strips the incoming HDMI signal into separate video and audio streams. While audio stream is decoded, the video 

streams are unaltered and handed-over to the HDMI output. Nevertheless, the HDMI clock is being regenerated, and some report that it results 
in a slightly improved video quality when used with longer HDMI cables, much like adding a HDMI switch.

Are there any known issues that I should be aware of?

The followings are known issues and their corrective actions:
Strange HDMI behavior such as losing sync, blank video, green screen:
First, check and make sure you have a good HDMI cable by swapping it out with another cable.

Go to:  Menu > Setup > Options

:

Turn CEC Control = OFF
Turn HDMI Audio Out = Amplifier
Turn HDMI OFF Through = OFF
