Combine
The Combine component (see Figure 8-1) adds multiple input signals
together and sends the sum to a single output. In QuickMAPs, 2-to-1,
3-to-1, and 4-to-1 combines may exist. The combine’s default attenuation
is set so that the combine’s output level is unity. In every case the
attenuation applied to each input channel may be independently adjusted
between -96 dB and 0 dB, or muted, and the polarity applied to each
input channel may be independently set to + or - (in-phase or out-of-
phase). Attenuation and polarity are applied to the input signals before
they are added to the combination.
Bypassing a combine sets all attenuations to 0 dB and all polarities to +
(in-phase).
Input Attenuators
The input attenuators can be adjusted three ways:
Using the Knob
Click on the indicator on the knob and while continuing to hold
down the mouse button, move the mouse in an arc. The
numbers in the box below the knob will change. When the
desired level is reached, release the mouse button.
Using the Text Box
Click in the box. Using the Back Space and/or Delete keys
erases the current entry and enters the new level. Be sure to
press the Enter key after the entry is made. Clicking outside the
text box without pressing the Enter key will cause the setting to
return to the number that it was before a change was attempted.
Alternatively, click and drag across the number in the box to
highlight the number in it. Type the new setting and press the
Enter key when finished.
Using the UP/DOWN Arrows
To increase the level, click on the up arrow. To decrease the
level attenuation, click on the down arrow. The amount of
increase or decrease is controlled by the fine/coarse control.
