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.
