7 Channel Surround-Sound Amplifier Crestron CNAMPX-7X200
CNAMPX-7X200 Symbol Input Signal Descriptions
INPUT DESCRIPTION
Main_Power This signal activates the main operating power to the CNAMPX-
7X200 circuitry. (Master Switch and front panel POWER switch
must be set to On.)
High/1=power on
Low/0=power off
Enable_Temp_Rpt This signal selects whether or not the Temp(x10) analog output
described in the next table is updated with the CNAMPX-7X200
enclosure temperature.
High/1 = update temperature
Low/0/default = temperature not updated
Temp_Format This signal selects the format of the temperature to be displayed.
High/1 = Celsius
Low/0/default = Fahrenheit
CNAMPX-7X200 Symbol Output Signal Descriptions
OUTPUT DESCRIPTION
OverRide_F This signal indicates that the audio output override function is
activated.
High/1 = override active
Low/0 = override not active
Temp(x10)
(analog)
This analog signal corresponds to the ambient temperature
within the CNAMPX-7X200 enclosure. The temperature reports
approximately once every 2-seconds. (The Enable_Temp_Rpt
entry in previous table must be driven high/1 for this to update.)
The temperature reports in tenths of a degree (eg, 725
corresponds to 72.5 degrees).
The OverRide_F signal is typically used to provide a visual indication (e.g., on a
Touchpanel screen) that the Override function has been selected, preventing program
control of the audio output. The temperature report signal is typically used under
program control to activate amplifier power shutoff when the temperature reaches a
predetermined level.
