If your room has very low ambient noise, set the decay rate to fast. This reduces the effects of echo and reverberation. If you hear ambient noise “swoosh” down while the microphones decay, set this value to either medium or slow.

Manual Ambient

This setting is relevant only if the adaptive ambient mode is off on a mic channel (see Adaptive Ambient on page 22). The best results are usually achieved when the adaptive ambient mode is off. However, if you need to set the ambient level to a fixed value, turn off the adaptive ambient mode on the desired microphone channels. A manual ambient setting is a global setting and will affect all mics equally which are set to adaptive ambient off. The ambient level ranges from 0dB to -70dB with the default setting at -30dB.

To determine ambient level

1.Check your current gate ratio from the Gate Parameters menu. Make a note of the value. Example: “Gate Ratio: 15.”

2.Select Manual Ambient from the Gate Parameters menu. Press Enter to change the dB value.

3.Scroll up or down through the dB values until the mic gates on (gating is indicated when the mic LED lights up). Individual room conditions will determine whether you need to scroll up or down. When the LED flickers, the dB value indicated on the LCD display is the ambient level of the room.

4.Deduct the gate ratio value from the ambient level value you have just determined. For example, if the ambient noise level of the room is identified as -50dB and the gate ratio is 15, the manual ambient setting would be -35dB.

RS-232

There are four RS-232 parameters that can be adjusted via the front panel LCD (see Figure 2.12). These parameters are baud rate, flow control, modem mode, and clear password.

Baud Rate

This parameter allows for the AP800’s RS-232 port communication rate to be controlled. There are three settings: 9,600 (default), 19,200, and 38,400 baud (bps). To set the baud rate, scroll through the three settings to select the desired baud rate, then press Enter.
