I-Tech HD Series Power Amplifiers

4 Advanced Operation

Bandpass Gain: In each channel of the I-Tech HD’s DSP, just before the output limiter and after the preceding fi lter, is a gain block (not shown on the Signal Path block diagram). Bandpass Gain adjusts the gain of this block between -24 dB and +24 dB.

Adjusting the bandpass gain in the LCD screen makes it easy to vary the level of subwoofers, midrange drivers and high-frequency drivers.

Bandpass Gain

Input Delay: Sets the input signal delay in each channel. Turn each channel’s Encoder knob to vary the delay. The delay step size is speed sensitive. Pressing the encoder enables or disables the Delay.

Below each channel’s delay setting is the equivalent distance in feet and meters. For example, 10 ms is the signal delay of sound traveling 11.3 feet or 3.4 m.

Front Panel Blackout: This screen lets you black out the front panel display unless 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 is enabled, an Encoder press/turn will “reactivate” the display. If no button is pressed/turned for 5 seconds, the display will return to blackout mode.
