Ampliﬁer DSP Selection Screen, Indicators

I-Tech HD Series Power Ampliﬁers

4 Advanced Operation

4.8.1 Ampliﬁer DSP Selection Screen

On the left of this screen is the Input Signal Level Monitor (explained later on this page). On the right side are rows of DSP selection buttons for each channel. When you click on a button, a control panel opens for that button’s function.

Also on the right are buttons that open control panels for these functions:

•Ampliﬁ er mode (dual, bridge-mono, input Y)

•Signal generator (pink noise and sine wave)

•Ampliﬁ er information

•Recall and store presets

•Preset manager

•Apply to others (apply this ampliﬁ er’s DSP settings to other devices)

We’ll explain each of these functions on the next several pages.

4.8.2 Ampliﬁer Mode

This is switchable between dual, bridge-mono and 1x2 (input Y).

Operation Manual

4.8.3 Input Level, Mute, Link, Level Meters, and Indicators

This panel is on the left side of the I-Tech main control panel shown above. Channel 1 and 2 Level Controls set the input signal level of each channel. Each channel can be muted, and both faders can be linked with the Link button.

Input Signal Level Meter

The measurement range is from 0dBFS to –40dBFS with 0.5dB resolution. Each audio channel has the following monitors:

•Switched Audio Input: This meter shows only the switched (selected) audio input after the Input Audio Router.

•Clip Indicator

Output Signal Level Meter

The measurement range is from 0 dB to –40 dB with 0.5 dB resolution. The monitors are scaled so that 0 dB is referenced to the full rated output voltage of the ampliﬁ er. The left meter is rms and the right meter is peak. An output clip indicator is provided.

Indicators

Temp: Lights if the temperature of the ampliﬁ er is too high and the ampliﬁ er is near shutdown.

Green: Thermal headroom used up is less than 59%.

Yellow: Thermal headroom used up is 60-80%.

Red: Thermal headroom used up is more than 81%.

Limit: Lights when the ampliﬁ er signal is being limited.

Load: Lights when the load impedance is out of range.

Ready: Lights when the ampliﬁ er is on and ready to supply power.
