Output & Levels tab
The Output & Levels tab is used to set the signal levels used in the subsequent measurements. The procedure
on this page will also confirm that the nanoAVR DL is able to play test signals. Before proceeding, make sure that
you have an active HDMI source connected to the selected input (HDMI 1 or HDMI 2) of the nanoAVR DL.
Then follow this procedure:
1.
Set Output volume all the way down, at -80 dB. Set the volume control of the connected AVR or processor
about halfway (or around -20 dB) and increase it later if needed.
2.
Click on the Test button for the left channel and gradually increase Output volume. You should hear pink
noise playing from the left speaker. Continue to increase volume until it is at a moderate level, such that
your voice would have to be raised to converse with someone sitting next to you.
3.
Set the Input gain slider so that the blue bar on the level meter is about in the middle of the green section,
or around -12 dB:
4.
Click again on the Test button for the left channel to stop the test signal.
5.
Click on the Test button for each of the remaining channels. If any channel is not in the green zone, use the
Channel volume sliders to adjust the relative volume of the channels. (Some readjustment of Input gain
and Output volume may also be needed.)
6.
When done, click the Proceed button.
1. The nanoAVR DL requires an active video signal input in order to output audio data. This is
because HDMI inserts audio data between the video frames. If you do not hear audio when pressing
a Test button, ensure that an HDMI video source is connected, selected, and not asleep.
2. The number of output channels signaled to the AVR is the same as the number of channels
signaled by the HDMI source above. If this is a two-channel source, you may only hear test audio on
two channels. If this happens, set the HDMI channel mode to “7.1 ch” (see page 41).
