SAM1-3GM and SAM1 MADI Combined User Handbook Version One Issue 1
2.14 Setup Menu 2
Accessed via Setup, Setup Menu 2 includes additional functions used to tailor SAM1 3GM to meet
customer’s specific operational needs.
Setup 2 Menu includes options to protect User Presets, GPI Action, External and Internal
Loudspeaker Mute, and to access the Software Management Menu.
Setup Menu 2 looks like this
2.14.1 User Save Menu
The User Save Menu enables an Engineer or Technician to Lock or Unlock the User Preset
management system onboard SAM1. In Locked mode a user is able to recall the Home Preset
but unable to save or recall memories from internal or external (USB or SD Card) locations.
2.14.2 GPI Menu
The GPI Menu enables an Engineer or Technician to select whether GPI inputs respond to
Latching or Momentary closures from external devices. The GPI connector can be used to Cut/Dim
the internal and external Loudspeakers, and to recall User presets 1 to 5. The pin-out is described
in Section 3.
In Momentary Mode, Dim and Cut GPI's latch in a toggle manner, i.e. one closure to ground
toggles the function ON; the next ground toggles it OFF. In an ON state; the GPI pin is driven low
to allow an LED to be fed from the port. This LED drive is briefly pulsed high at about 100Hz to
allow the port to be read whilst it is driving.
The preset recall GPI’s in ‘Latching’ mode are mutually exclusive.
2.14.3 Internal / External Loudspeaker Mute
The SAM1 is designed to be used with either Internal or External Loudspeaker Systems. Users
may wish to define User Preset conditions which associate the operation of the unit with internal
speakers for in one state and external speakers in another. To facilitate this kind of hybrid
operation the SAM1 is equipped with individual Loudspeaker Mute buttons which can be
configured with different functionality dependant upon their desired use and then saved to
individual presets.
In the event that SAM1 is installed for use with external speakers only with the intention to mute the
internal speakers, a DIP switch on the rear panel can be used to override the Internal LS Mute
button in Setup 2 Menu.
