Thermal Errors:
This screen lets you view thermal errors without using the
control software. A
thermal error
occurs if the amplifier thermal % exceeded
the value set with the
Thermal 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, press and release an Encoder. The display will prompt you
to confirm your choice by pressing and holding the Encoder.
NOTE: You must use System Architect to enable error reporting and set its
limits.
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.
Low Limit Load Errors:
This screen lets you view low-load errors without
using the control software. A
low limit load error
occurs if the load
impedance falls below the value set with the
Low Limit spin control
on the
Amplifier Settings page in System Architect.
When an error occurs, the count displayed in this screen is incremented, and
the operating time since the error is displayed.
To clear this screen, press and release an Encoder. The display will prompt you
to confirm your choice by pressing and holding the Encoder.
NOTE: You must use System Architect to enable error reporting and set its
limits.
High Limit Load Errors:
This screen lets you view high limit load errors
without using the control software. A
high limit load error
occurs if the load
impedance rises above the value set with the
High Limit
value
on the
software Control Panel.
When an error occurs, the count displayed in this screen is incre mented, and
the operating time since the error is displayed.
To clear this screen, press and release an Encoder. The display will prompt you
to confirm your choice by pressing and holding the Encoder.
NOTE: You must use System Architect to enable error report ing and set its
limits.
Line Voltage Errors:
This screen lets you view line-voltage errors without
using the control software. A
line voltage error
occurs if the line voltage falls
outside the values set with the
High/Low Limits slider
on the Line Voltage
Page of the Control Panel.
When an error occurs, the count displayed in this screen is incre mented, and
the operating time since the error is displayed. The “Low” and “High”
indicators show whether the line voltage was below or above the line-voltage
limits.
To clear this screen, press and release an Encoder. The display will prompt you
to confirm your choice by pressing and holding the Encoder.
NOTE: You must use System Architect to enable error report ing and set its
limits.
Exit:
To exit the Alert Menu and go to the Attenuation screen, press
Menu/Exit
once.
Load Monitoring:
Press an Encoder knob to turn speaker load monitoring on
or off for either 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.

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, 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.
