Audio calibration
Because HDMI and optical audio can connect to a
variety of equipment, their output may be delayed
by a perceptible amount compared to the analog
output directly to speakers.
If a single Nexus Q is connected to both analog
speakers and additional equipment, via either
HDMI or optical output, you can adjust the output
from either port to compensate for such delays.
Important: You can calibrate the HDMI and optical
outputs with the analog output of a single Nexus
Q. You don't need to calibrate one Nexus Q's
analog output with another's. This is taken care
of automatically.
Before you begin, make sure:
• The left analog outputs (those marked L) of
your Nexus Q are connected to a speaker.
• The HDMI or optical audio output of your Nexus
Q is connected to equipment that is turned on.
• Verify that both left channels (one analog and
the other HDMI or optical) are working. Only
the left channel from each output is used
during calibration.
If possible, move the speaker connected to the
Nexus Q's left analog output as close as possible
to the left speaker of the TV or other equipment
connected to the HDMI output.

Hold your phone or tablet midway between the
analog speaker and the other sound source, and
follow these steps:
1. From the Nexus Q app, touch the name of the
room where the Nexus Q is set up.
2. Touch Advanced > HDMI or Optical out.
3. Touch Auto calibrate and follow the
instructions.
When you're finished, you can adjust the delay
further manually.
4. When you're satisfied, touch Save.
You can also choose Manual calibrate in step 3 to
jump directly to manual calibration.
