Montarbo E616A Instruction Manual page 66

On the upper-right side of the windows are displayed both the ambient
(external) temperature (Ta1) and the power amplifier's temperature (Tf1).
When two speakers are linked to form an L/R pair the window will display
four temperatures values: Ta1 and Tf1 for the first speaker, Ta2 and Tf2 for
the second.
On the right side there is displayed the volume control (output
attenuation) window.
It is possible to adjust the volume with the OutAttn knob.
The attenuation range is from 0.0 to -32.0 dB, with 0.5 dB increments.
The current value is displayed under the control knob.
The Delay window displays the value of the global delay, set with the two
arrow buttons.
The value can be adjusted by one millisecond increments (about 34 cm:
13 inches); the maximum value is 310ms (more than 100 meters: 334 feet).
The Mute button will mute the speaker.
If a speaker is part of an L/R pair, any control in the command windows
will operate on the two linked speakers at the same time: the Mute button,
the OutAttn knob, the Equalizer's controls and the Delay setting will
operate on both of them.
This way, it is possible to control the two paired speakers from a single
command window.
