Channel Volume Adjustment
The Cinema Reference also permits you to adjust volume levels of specific channels while you are
listening to a component. This will allow you to for example, raise the center channel volume level, if
the movie you are watching has dialogue that is not loud enough.
To access any of the eight channels and raise or lower their levels:
1 Turn the Channel knob clockwise until the display’s second line reads PUSH TO EDIT while
the top line indicates the channel you can select and its current volume level in DB. Then
press the Channel knob.
2 Turn the Channel knob to raise or lower the channel’s volume level.
3 To proceed to alter other channel levels, press the Channel knob, then turn the Channel knob
to the next channel you wish to alter and press the Channel knob to repeat step 2. To exit
this menu, turn any knob other than the Channel knob.
Solo Mode
The Cinema Reference Mach II features a testing mode that is unique to ADA. Solo Mode permits you
to have just one speaker playing while all other channels are muted. In order to achieve this on lesser
preamps, you would need to lower the level of all channels and then raise just the channel you wish to
hear. In Solo Mode, you can select just one channel and easily switch between single channels.
Solo Mode is useful when trying to determine if you have a damaged speaker or driver. It is also useful
for determining if a speaker is out of phase with the other speakers.
Solo Mode is also ideal when trying to get an understanding of how multi-channel recordings are
mixed, as you can select to listen to just one channel at a time. This is particularly useful when playing
multi-channel music recordings.
To fully understand the use of Solo Mode and the power of multi-channel music, ADA suggests playing
the DTS version of the Eagles “Hell Freezes Over” CD or DVD. The DTS version of these discs
contains a bonus track, “Seven Bridges Road”. Please note, that this is a 5.1 mix and not a 7.1 mix.
As such, it is best to select a DTS playback mode that leaves the back surrounds off, at least for a Solo
Mode test. In this powerful mix, each of the Eagles band members is recorded on his own speaker
channel; five band members hence the five channels.
Begin to listen to the track and about halfway through, return to the beginning and enter the Solo
Mode. As you skip through the various channels, you will notice just how discrete each vocalist is. As
you return to playing all channels at once, you will have realized firsthand, the power of multi-channel
music as the harmonies on this recording are blending, not in some mixing console, but live, in your
home theater.
To activate Solo Mode:
1 Turn the Channel knob clockwise until the display reads PUSH TO EDIT SOLO MODE, then
press the Channel knob.
2 Turn the Channel knob to select the channel you wish to isolate and listen to. To return to the
previous menu level, turn the Channel knob clockwise until the second line of the display
reads BACK TO MAIN and press the Channel knob. To completely exit this setup menu,
turn any knob other than Channel.
