Pin 1

Connecting pin 1 to ground (pin 9) will place the unit into Bypass mode.

 

 

This will occur regardless of the setting of the Bypass mode parameter in

the I/O control menu. However, enabling bypass in the menu will also place the unit into bypass, regardless of the presence of this connection.

Pins 2–4 In order to select one of these modes, a high-to-low transition should be placed on a pin. The input format corresponding to the pin will be selected, as long as the selection does not conflict with another setting (such as clock source). As only one of these settings can be selected, the input formats will be active in the order that they are selected. A low-to- high transition on these pins will not have any effect.

Pins 5–8 These operate in the same way as pins 2–4. The relevant preset will be recalled immediately if a high-to-low transition occurs. If pin 1 is grounded, then bypass operation will be active irrespective of the setting of Bypass mode within the preset.
