Output Parameters
There are two main submenus under the outputs menu tree: Outputs 1–8 and Outputs
A, B, C, D. The two main submenus each contain the same menus at the next menu
depth: gain adjust, mute, and NOM (Figure 2.16). Each parameter is applied to the
respective outputs (1–8 or A–D).
Outputs 1–8, A–D
Gain Adjust
This adjusts each output’s gain (ranging between -20dB and 20dB). In conjunction
with the LCD readout and the LED bar meter, all gated outputs can be calibrated for
the right level on the mix bus. Default is 0dB.
Mute
This parameter mutes a particular output channel.
NOM
Number of open mics (NOM) corrects for increased output level when more than one
microphone is gated on. As microphones gate on, the AP800 reduces the level
according to the number of active microphones. This mode can be turned on (default
for outputs A-D) or off (default for outputs 1-8). NOM adjusts at 10log of the
number of open microphones, or approximately 3dB every time the mic count
doubles.
Routing Parameters
When programming routing through the front-panel LCD, there are various
submenus (routing destinations) below the Routing menu (see Figure 2.17): route to
output 1–8, route to output A–D, route to G-Link X–Z, route to subbus 1–2, route to
EC reference 1–2, and route to G-Link EC reference. Select one of these parameters
and press Enter to scroll through the inputs available for routing to that output.
When the desired input is visible, press Enter to route it to that output.
Routing consists of determining which inputs go to which outputs. When
considering routing, refer to the default routing matrix (see Figure 2.18). There is
also a routing matrix worksheet at the end of this manual (see Appendix G).
Subbus 1, 2
The subbus parameters allow control of gain (attenuation) to mix audio from the
microphones into the speaker audio. There are two parameters that can be set:
subbus 1 and subbus 2. Each gain can be adjusted in dB.
