PI ACOUSTIC PROCESSOR

Display

Multi-functional OLEO graphics display for information such as preset and audio signal level. It also show menu item to view system setting as required 

Combined push-and-turn dial to access the edit menu and select and edit individual menu items.

Input Signal LED indicating

Indicate input connection status. When you connect this device to other host, the LEDs indicate corresponding Channel port connection status at back panel.

LEDs indicate as below :
-CLIP(RED). It means current CH input signal overload, the led lights up when the signal>15dB.
-SIG(GREEN). It means some signal input from current CH port, the led lights up when the signal >-30dB.

 Input Channel MUTE Button

Press CH1-4 buttons, the corresponding background LED light, which means to mute signal from selected channels .

Output Signal Indicating LED

Indicate output connection status. When you connect this device to other hosts, LEDs h ere indicate corresponding XLR port connection status at back panel.

LEDs indicate as below :
- CLIP(RED). It means current XLR output signal overload, the led lights up when the signal >15dB.
- SIG(GREEN). It means some signal output from current XLR port, the led lights up when the signal >-30dB.

Output Channel Select Button

Press CH1-8 buttons, the corresponding background LED light, which means to mute signal can output from selected channels.

Status LED Indication

LED indicating as below:
- COMM.(GREEN). Power on the product and connect it with PC by router, then open the product software control page on PC, it lights if communication is common; while it turns off if communication is fault .

- FAULT(RED). It lights when DSP runs fault, you can see fault information on LCD screen, see details in section 1 about LCD Screen. At this time please check your device configuration.
