Present memory change function has been assigned by default; Pins 1 through 4 are assigned to Preset Nos. 1 through 4, respectively. Preset Nos. 1 through 4 can be individually recalled by shorting the terminals 1 through 4 to terminal C.
(5) Channel Select Select the target channel of which control output volume and output mute are to be controlled. (6) [Disable] button/ [Enable] button Clicking the [Disable] button disables control from the Contact input, turning into [Enable] button. Preset number of the controls performed before clicking the [Disable] button is retained, but both output volume and output mute controls are cleared. To control again, click the [Enable] button.
15.3. Function Assignment to the Contact Inputs 15.3.1. Preset memory change [When in Direct mode] Step 1. Set the Mode to [Direct] and Function to [Preset]. Step 2.

[When in Binary mode] Note: When changing Preset in Binary mode, either output volume control or output mute control can be assigned to other Pins.
15.3.2. Output volume control Gives an offset value to the value set to the output attenuator. Notes • Output volume control can be performed only to the DP-SP3 unit targeted by the contact input. • Group the output channels, then perform controls in groups. • The channels belonging to the same group are equal in the obtained offset value but not in the output attenuator value. • It is not possible to assign the same channel to 2 or more groups.
15.3.3. Output mute control Assign the Mute ON/OFF function to the Pin. Notes • Output mute control is only available to the DP-SP3 unit targeted by the contact input. • Group the output channels, then perform controls in groups. • When “Pulse” is selected for the control method, even if the unit’s power is switched off, the output mute state can be recalled when the power is switched on again.
15.4. List of Functions Assignable to Pins Functions assignable to Pins 1 through 4 are listed below.
