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

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.

The measure ment 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 mea surement 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.
