Output parameters

There are two main submenus under the outputs menu tree: Output 1–4 and Output A–D/Telco Out. The two main submenus contain the same menus at the next menu depth: gain adjust, mute and NOM (Figure 2.18). Each parameter is applied to the respective outputs (1–4 or A–D/Telco Out).

Output 1-4, Output A-D, Telco

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 simply 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 AP400 reduces the level according to the number of active microphones. This mode can be turned on (default for outputs A-C, Telco) or off (default for outputs 1–4, and output D). 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 multiple submenus (routing destinations) below the Routing menu (see Figure 2.19): route to output 1–4, route to Telco Out, route to output A–D, route to Subbus, route to G-Link X–Z, route to EC reference and PA, or route to G-Link Ref. Select one of these parameters and press Enter to scroll through the inputs available for routing to that output. When the correct input appears, 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 (Figure 2.20). There is also a routing matrix worksheet at the end of this manual (see Appendix F, page 66).

The audio matrix is made of sources and destinations. There are 17 possible input sources and 13 destinations on the AP400 matrix.
