7 Advanced Operation
7.2.2 MONiTOR MeNU
This menu lets you monitor the status of the amplifier.
Load Monitoring: Press a channel icon to turn speaker load monitoring on
or off for a channel. When load monitoring is on, the load connected to the
amplifier output is displayed. The text below the reported load indicates
whether the value is within the limits set in Sys tem Architect. OFF means load
monitoring is off. LOW means the load is below limits. HIgH means the load is
above limits. NORMAL means the load is within limits.
(Output must be sufficient)
Thermal %: This indicates the amplifier temperature in percent, where 100%
is the maximum allowable temperature. If Thermal % reaches 100%, the
amplifier is out of thermal headroom and has shut down (or will very soon).
Measurements are shown for Channel 1, Channel 2, Channel 3, Channel 4,
and PSU.
Operation Manual
Thermal Temp deg. c: This screen displays the temperature in degrees
Celsius of the Ch. 1 output devices, Ch. 2 output devices, Ch. 3 output
devices, Ch. 4 output, and the power supply.
Ac Voltage: This shows the AC line voltage at the AC cord inlet to the
amplifier.
Operating Time: This displays the number of hours the amplifier has been
on since manufacture. Like a car's odometer, it shows the total amount of
operating hours and cannot be reset. All I-Tech HD amplifiers come with a
variable amount of operating time on them due to burn-in and testing before
shipping.
Watts Output: This displays the slow-averaged continuous output power of
each channel in watts.
7.2.3 ALERT MENU
This menu displays a wide variety of errors in the signal, amplifier, or load.
Amp Output clip errors: A clip error occurs if the number of clip events in
the amplifier output exceeds the value set with the Count slider (within the
time set by the Time slider) on the Amplifier Settings page in System Architect.
When an error occurs, the count displayed in this screen is incremented, and
the operat ing time since the error is displayed.
To clear this screen, tap a channel icon.
