I-Tech HD DriveCore Series Power Amplifiers
7 Advanced Operation
AeS input Status: "Lock" indicates that an AES cable is plugged in and the
amplifier is receiving (and locking to) the AES phase logs logs. "No Lock"
means that the amplifier is not receiving, or is not locking to the AES
clock pulse.
cobraNet input Trim: Turn the Encoder knob to vary the gain of the
CobraNet digital signal for Channel 1: -100.0 dB to +20 dB. See Figure 4.4 for
more information.
Operation Manual
Bandpass gain: In each channel of the I-Tech HD's DSP, just before the
output limiter and after the preceding filter, 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 driv ers.
Output Polarity: Press each channel icon to toggle the output signal polarity
between + and –.
input delay: Sets the input signal delay in each channel. Turn the 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.
Output delay: Sets the output signal delay in each channel. Turn the 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.
