• Step 2. Align the module board with the top and bottom guide rails, and press in.
• Step 3. Using the screws supplied with the module, secure the module to the rear panel.

Output Connections

Speaker connections
Each amplifier has 3 speaker outputs: 4 Ω, 25 V, and 70 V. Use only one of these outputs for connection. Class 2 wiring may be used.

Note : Impedances in the figures below represent total speaker load impedance.

MOH output connection
The MOH output is 0 dB*, 600 Ω, and balanced (transformer–isolated).

Line output connection
The Line output is 0 dB*, 600 Ω, and unbalanced.
0 dB = 1 V

Manual Mute Terminal Connection
Closing between the manual mute (+) and (–) terminals causes the Mute Receive inputs to be muted (the inputs set to be muted).

Remote Volume Control Connection
The mixed output level at post-input volume controls can be adjusted with an external remote volume control. Note that individual input volume control positions limit the maximum output level adjustable with the remote volume control. Be sure to avoid turning down all input volume controls.

Notes

• Negative terminal should not be grounded. Never connect it to the unit’s chassis nor other circuit ground.
• Only a volume control can be connected to this terminal.

MUTING FUNCTION

Manual Mute

Step 1. 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

Manual Mute

• Step 1. 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 Receive and Mute Send functions to the same input.

• Step 2. Close between the Manual mute (+) and (–) terminals.
  • The Inputs set for Mute Receive in Step 1 are muted.
• Step 3. Open between these terminals.
  • The signal being muted returns gradually to its original level in about 1 to 5 seconds.

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 s witch 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.

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

CHANNEL BROADCAST
Input signals set in Chapter 8 are output to the MOH output. 2-channel broadcast can be performed when the unit is used in conjunction with the optional BA-235 (35 W) or BA-260 (60 W).

(Example)
When MIC, LINE 1/TEL, LINE 2, LINE 3, and MODULE input signals are output to the Zone 1, and LINE 2 input signals to the Zone 2.

OPERATION

After completing all connections, turn on the power switch, and check to confirm that the power indicator lights.

Note
When the heat sink temperature exceeds 105 °C (221 °F), the protection circuit begins to operate to disconnect the output from the circuit. The disconnected output is automatically restored as soon as the temperature returns to the normal operating range.
