I-Tech HD Series Power Amplifiers

4 Advanced Operation

4.8.14 Amplifier Information

Information about the amplifi er is stored in the software system inventory and is displayed on the software control panels. Information includes manufacturer, model, date code, and serial number. The green items can’t be edited.

Channel Labels: Each amplifi er includes two labels that you may edit for your own use. Simply type in the text areas. Use these labels to describe the channels of your amplifi er. These names will appear in the individual processing blocks.

Attenuator Limits: This lets you set a limit on the attenuators. You can set the maximum attenuation from 0 dB to –100 dB. Once set, attenuation cannot be adjusted beyond this level.

NOTE: The attenuator setting must be below the attenuator limit that you are trying to set. For example, if the attenuator is set at –3 dB, you cannot set the attenuator limit below –3 dB unless you decrease the attenuator level.

Blackout Mode: This button lets you blackout the front panel display until you press a front-panel button or turn an Encoder. This feature turns off the LCD backlight and all front panel LEDs except for the fault LEDs and power- switch green LED. After blackout mode is enabled, an Encoder press/turn will “reactivate” the display. If no button is pressed/turned for over 5 seconds, the display will return to blackout mode.

4.8.15 Apply to Others

This screen lets you apply the System Architect settings for your I-Tech HD amplifi er to other I-Tech HD ampli- fi ers in the venue fi le.

4.8.16 Delay (Latency)

Due to the nature of DSP processing, there is some inherent delay or latency within the I-Tech’s DSP. These latencies are shown in Table 4 below:
