MENU DESCRIPTION
GPIO mode 3 (CP4SW simple remote mode)
This mode is intended to be used with momentary ‘High’ signals (like push buttons). It is
recommended to use the Yamaha CP4SW remote control panel for DME. Connect the
button 1 to 4 to the GPI 1 to 4, and each LED to GPO 1 to 4. Here is the detail:
Pin Name
In/Out
On each Impulse (From 0 to 1 and back to 0)
GPInput 1
In
Going to ON or to Stand-by mode
GPInput 2
In
One step of volume increase
GPInput 3
In
Mute/Attenuate or Unmute all channels
GPInput 4
In
One step of volume decrease
Pin Name
In/Out
Meaning when set to 0
(Default)
Meaning when set to 1
GPInput 5
In
Mute mode
Attenuate mode
GPOutput 1
Out
Blink if NXAMP in Stand-by, 1 if NXAMP ON.
GPOutput 2

GPOutput 4

GPOutput 5
Out
GPInput 1 impulse out to other amp
GPOutput 6
Out
GPInput 2 impulse out to other amp
GPOutput 7

GPInput 3 impulse out to other amp
GPOutput 8
Out
GPInput 4 impulse out to other amp
When an impulse of at least 3 seconds is detected on GPInput1, amplifier will go from ON
to Stand-by state or from Stand-by to ON state.
When an impulse is detected on GPInput2, the volume of all channels is increased by one
volume step (see volume menu for steps values).
When an impulse is detected on GPInput3, all the channels are muted/attenuated
(depending on GPInput 5 status) or Unmuted. Front panel mute is still working.
When an impulse is detected on GPInput4, the volume of all channels is decreased by one
volume step (see volume menu for steps values).
When GPInput5 is set to 0, the Mute/Attenuator function of the GPInput 4 is set Mute
mode. When GPInput5 is set to 1, the mode is set to Attenuate (attenuation is roughly 20
dB).
GPOutput1 is blinking when the amplifier is in stand-by, and ON if the amplifier is running.
GPOutput2 is blinking each time an increase volume command is received, and is ON when
volume is set to max.
GPOutput3 is ON when all channels are muted, OFF in other situations.
