Input Parameters

There are three main submenus under the inputs menu tree: Inputs 1–8, Input

Global; Inputs A, B, C, D; and Subbus 1–2.

Inputs 1–8, Input Global

The parameter submenus below this level control how an input channel deals with input audio. All parameters described can be applied to Inputs 1–8 or Input Global, which applies the selected parameters to all eight mic inputs. The thirteen mic input parameters are shown in Figure 2.13.

Gain Adjust

This adjusts the level for each gated input’s gain (ranging between -20dB and 20dB). In conjunction with the LCD readout and the LED bar graph, all gated inputs can be calibrated for the right level on the mix bus. The default setting is 0dB.

Mic/Line Input

Each input defaults as a microphone level (55 or 25dB gain) but can be switched to a line-level input (0dB).

Mic Activation

 

 

 

 

 

 

Each input defaults to the auto-gate mode, but can be switched to manual mode

 

 

 

(manual gate on, manual gate off, gate override on, gate override off). Auto-gate is

where a microphone does not gate on until audio is present at the mic. The AP800

 

 

 

decides to gate the microphone on or off based on parameters set elsewhere in this

 

 

 

submenu (i.e., gate ratio, etc.). Manual On activates a microphone unit until it is

 

 

 

manually deactivated. Manual Off deactivates a microphone until it is manually

 

 

 

activated. In both cases, this can be done via the Control/Status port. Override On

 

 

 

activates a microphone but does not allow it to contribute to mixing parameters,

 

 

 

such as set in NOM, maximum number of microphones, etc. Override Off deactivates

 

 

 

the mic.

 

 

 

Mute

This parameter mutes a particular mic channel.

Phantom Power

Each input will default with 24V phantom power enabled, but can be switched off to accommodate signals not requiring phantom power.

AGC

Each input can use automatic gain control (AGC). This feature keeps softer and louder talkers at a consistent level. This feature is disabled when shipped from the factory. The target gain is 0dB and adjusts at 2dB per second. The AGC start
