MENU DESCRIPTION
Pin Name In/Out
Meaning when set to 0
(Default)
Meaning when set to 1
GPInput 1 In Power amp can start Do not start power amp
GPInput 2 In Analog input unmuted Analog input muted
GPInput 3 In Digital input muted Digital input unmuted
GPInput 4 In Scene 1 is recalled Scene 2 is recalled
GPInput 5 In NXAMP is ON NXAMP is in Stand-by
GPOutput 1 Out Power amp has started Power amp not started
GPOutput 2 Out Reflects the GPInput 2 status
GPOutput 3 Out Reflects the GPInput 3 status
GPOutput 4 Out Reflects the GPInput 4 status
GPOutput 5 Out CH 1 no current out CH 1 current out
GPOutput 6 Out CH 2 no current out CH 2 current out
GPOutput 7 Out CH 3 no current out CH 3 current out
GPOutput 8 Out CH 4 no current out CH 4 current out
When starting, if GPIO is set to mode 2, the NXAMP will wait that its GPInput1 pin goes
‘Low’ to start the amplifier part (big power supplies). Once started, it will put its GPOutput1
pin ‘Low’ also, so several amplifiers can be linked together.
If GPInput2 is ‘High’, the analog inputs will be muted. If GPinput2 is ‘Low’, the analog
inputs will be unmuted.
If GPInput3 is ‘High’, the digital inputs will be unmuted. If GPinput3 is ‘Low’, the digital
inputs will be muted.
If GPInput4 is ‘High’, Saved Scene number 2 will be recalled. IF GPInput 4 is ‘Low’, Saved
Scene number 1 will be recalled. Warning: Any setup can be recalled, regardless of the
loudspeaker family.
If GPInput5 is ‘High’, Amplifier will go to Stand-by mode. If GPinput5 is ‘Low’, Amplifier will
go back to running mode.
GPOutput1 has been described above.
GPOutput2 reflects the GPInput2 (with a small delay and without glitches).
GPOutput3 reflects the GPInput3 (with a small delay and without glitches).
GPOutput4 reflects the GPInput4 (with a small delay and without glitches).
GPOutput5 to 8 reflects the "Signal" LED on the front panel (meaning current flowing on
the output). It will be possible to select a threshold in a next release (a Pilot Tone
generator will be implemented also).
