Telco

The telephone interface can be set to automatically answer an incoming call (Auto Answer On), or allow the call to be handled manually (Auto Answer Off). The interface can also be set to disconnect upon Loop Drop, Call Progress, Loop Drop + CP (call progress), or to disconnect manually (Auto Disconnect Off).

Input parameters

There are three main submenus under the inputs menu tree: Input 1–4, Input

A–D/Telco, and Subbus.

Inputs 1–4

The parameter submenus below this level control how an input channel deals with input audio. All parameters described can be applied to Input 1–4. The 12 mic input parameters (see Figure 2.14) are gain adjust, mic/line input, mic activation, mute, phantom power, AGC, high-pass filter, EQ status, chairman mic, adaptive ambient, echo canceller, and NLP adjust.

Gain Adjust

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

Mic/Line Input

Each input defaults as a microphone level input (55, 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 AP400

 

 

 

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

Figure 2.14. Mic Inputs 1–4 parameters

AP400 (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 microphone.

 

 

 

Mute

This parameter mutes the selected mic channel.
