M8™
USING CHANNELS 6 + 7 FOR -
If your main speaker system consists
of only 5 main speakers and no Surround Back Left & Right speakers, you
can redirect signals from the unused amplifier channels to the front speak-
ers or for Zone 2.
Speaker Distance
The Speaker Distance settings help the sound from each speaker arrive
at the listening seat at the same time. This provides a much more believ-
able and immersive sound environment. Precise delay settings should
be done by a trained professional with audio test equipment such as the
AudioControl Iasys HT to measure the precise sound delay. You can get a
rough delay setting using Auto Set-up. Measure the distance from the cen-
ter of a speaker to the seated ear position of the main listening seat. Write
each of these distances down and enter them into the Maestro M8 or use
auto setup.
Speaker Levels
It is critical to properly match the levels from each speaker to achieve a
correct sound stage. The realism is totally lost if the footprints of a person
walking across the screen change in volume as they move from left to cen-
ter to right. We strongly recommend using a test analyzer such as our Iasys
HT for this calibration. The levels are nearly impossible to judge by
ear alone. Though not as accurate as using the Iasys HT, you can use a
sound level meter for this adjustment.
With the internal test noise generator of the Maestro M8, adjust each
speaker for a sound pressure level (SPL) of 75 dB using a “slow” re-
sponse time on the SPL meter placed at the main listening position at
ear height.
Video Inputs
Settings to optionally assign a video source to each of the normal
“audio only” inputs. The default for each of these settings is “None”.
This is a great way to listen to the ball game over the Internet Radio
and watch it over your normal video display device, though timing might
be a little off.
