Amplifier Information

The Amp Info panel can be accessed by double-clicking the Amp Info button from the Main
CDi DriveCore Control panel (
Figure 32
information such as current firmware version, power supply temperature, channel temperature,
and more.
The following functions can also be configured
from the Amp Info panel:
1� Front Panel Lockout
When turned on, the front panel controls
will be locked to prevent tampering. The
exception is the Power button, which will
remain functional.
TIP: The front panel controls can also
be locked directly from the front panel,
however, if the front panel has been locked
from Audio Architect, it must be unlocked
from Audio Architect. See
Panel Lockout" on page 56
more information on locking/unlocking the
front panel controls from the front panel.
2� Front Panel Blackout Mode
Turns the front panel display on or off.
3� Amp Status Port
Selects whether a 2Hz square wave heartbeat
or +5VDC signal is sent to the Amp Status
pin on the AUX port — either can be used
to remotely determine amp health/status.
4� Mute Input
Determines which output channels will be muted when using GPIO Input 1 (pin 3). By default, a high condition will cause all checked input channels
to mute. Checking the Invert checkbox will invert the polarity/functionality, meaning a low condition will cause all checked inputs to mute.
5� Fault Output
Inverts the polarity/functionality of GPIO Output 1 (pin 1). When checked, GPIO Output 1 will indicate an amp fault when in a low state, rather than the
default high state. See
"System Protection" on page 60
6� Preset Recall Input
Loads one of two presets depending on the high/low state of Input 2 (pin 5) on the GPIO port. By default, these values are set to 0, which disables the
function.
7� Manual Aux Output
When this button is switched on, GPIO pin 2 (Output 2 ) will go high; when the button is off the state will be low. This provides a general purpose
output which can be used to control many external devices such as relays, indicators, PLC system controllers, or any other 3rd party device with logic
control inputs. This button can be controlled from its default loacation on the Amp Info panel, from a user-created custom control panel, using logic
functions in Audio Architect, or from a compatible HiQnet wall controller. The state of this button and the resulting output are stored/recalled along
with device presets.
