7.2. Automatic Mute
Step 1. Set the inputs to mute (Mute Send inputs) with the Function switch A.
Shift the DIP switches 3 to 5 to ON position to place each corresponding input in Mute Send (muting)
mode as follows.
• DIP switch 3: MIC input
• DIP switch 4: LINE 1/TEL input
• DIP switch 5: MODULE input
Step 2. Set the inputs to be muted (Mute Receive inputs) with the Function switch B.
Shift the DIP switches 1 to 5 to ON position to place each corresponding input in Mute Receive
(muted) mode as follows.
• DIP switch 1: MIC input
• DIP switch 2: LINE 1/TEL input
• DIP switch 3: LINE 2 input
• DIP switch 4: LINE 3 input
• DIP switch 5: MODULE input
Note
Avoid assigning both Mute Send and Mute Receive functions to the same input.
Step 3. Adjust the threshold level with the Mute Sensitivity Control at which the input placed in Mute Send
mode in Step 1 will activate the muting function.
Note
The audio signal level to activate muting is independent of input volume settings. So, the Mute
Receive input is muted if a signal enters the input placed in Mute Send mode in Step 1 even when the
input volume is turned down. To avoid unwanted muting caused by unintentional inputs such as
background noise and noise sound, it is recommended to cut the audio signal at the input equipment
(such as a microphone with talk switch).
Step 4. The Mute Receive inputs (set in Step 2) are muted when audio signals enter the Mute Send inputs
(set in Step 1).
Step 5. When the input signals are not present, the signal being muted returns gradually to its original level in
about 1 to 5 seconds.
8. MOH OUTPUT ASSIGNMENT
Inputs selected by the Function switch B can be output to MOH output.
Use the rear-mounted MOH volume control "LEVEL" to adjust the output level.
Notes
Following are precautions on the MOH output.
• Each individual input level setting cannot be performed (the volume control does not work). Adjust the
volume level at the input equipment as needed.
• Bass and treble controls do not work.
• Mute control does not work.
• Remote volume control does not work.
[MOH Output Setting]
Set the input to be output to the MOH output using the Function switch B.
The DIP Switch numbers correspond to the inputs as follows.
DIP switch 6: MIC input
DIP switch 7: LINE/TEL input
DIP switch 8: LINE 2 input
DIP switch 9: LINE 3 input
DIP switch 10: MODULE input
