The thinking behind these four presets is:
Tone Preset 1 - All speakers are active to only Speaker Group A. Here, one can simply adjust levels
up and down for bass and treble, effecting all speakers.
Tone Preset 2 - The front three speakers are on Group A (where the center channel is more similar in
size, driver configuration, etc. to the front right and left speakers) and the surround speakers are on
Group B. Note that the front speakers have different frequency points and that the subwoofer is not
active in either Speaker Group.
Tone Preset 3 - Only the front right and left speakers are on Group B. This setup takes into consider-
ation a system where the center speaker is more similar in size, driver configuration, etc. to the sur-
round speakers. Note that the front speakers have different frequency points and that the subwoofer
is not active in either Speaker Group.
Tone Preset 4 - Here all speakers are active on both Tone Groups A and B, which also have different
frequency points. As such, this option sets the tone control section up as a four band parametric
equalizer. The subwoofer is not active in either Speakers Group.
Please note, that the primary preset and current Cinema Reference Mach II setting is Tone Preset 1.
Here all speakers are assigned to Group A with a Treble frequency point of 6KHz and a Bass fre-
quency point of 260Hz. Both Treble and Bass levels are defaulted to flat (0dB). As the remote control
may offer a Bass and Treble up/down function, these buttons will offer a uniform bass and treble
control across all speakers.
If you are interested in the adjustment of the tone levels, ADA suggests first trying the three additional
presets shown above. You will want to listen to an actual source component when doing this. If you
prefer to assign either Tone Presets 2, 3, or 4 to Tone Preset number 1 (thereby erasing the current
Tone Preset 1), you can do so. This is discussed under Storing Tone Presets.
If you choose to use one of these presets as a basis for setting tone levels in your home theater,
thereby skipping the Speaker Group setup, continue with the next section, Recalling Tone Presets.
Recalling Tone Presets
To recall the Tone Preset 1:
1 Turn the Channel knob until the display reads PUSH RECALLS TONE PRESET 1 and then
press the Channel knob.
To recall any of the four Tone Presets:
1 Turn the Channel knob until the display reads RECALL/STORE TONE PRESETS and press
the Channel knob.
2 Turn the Channel knob so that the display’s top line reads RECALL while the second line reads
the TONE PRESET number you wish to recall and then press the Channel knob.
At this time, you can choose to modify the Speaker Groupings or skip directly to Treble and Bass
adjustment.
