10.2. Output Volume Control
• Closing the terminals for 250 ms or more causes an action to operate by 1 step*.
* Select the variation from “1 dB step,” “3 dB step,” or “6 dB
step” using the DP-SP3 PC Software.
• Maintaining the terminals closed for 250 ms or more causes a 1-step action to repeat every 800 ms for 3
times, followed by 1-step action repeating every 200 ms. Opening the terminals stops these continuous
actions.
Tip
Use the DP-SP3 PC Software to assign the function to terminals.
Read the separate DP-SP3 Software instructions.
10.3. Output Mute
There are 2 control methods to mute output: Closed control and Pulse control.
Use the DP-SP3 PC Software to select control method.
[Closed control]
Closing the terminals for 250 ms or more causes Mute to turn ON.
While, opening the terminals for 250 ms or more causes Mute to turn OFF.
[Pulse control]
Closing the terminals for 250 ms or more causes Mute to turn ON.
Mute turns OFF 250 ms or more after opening once and closing again the terminals.
Mute switches between ON and OFF each time open and closed states are alternately repeated.
