13. Multi Function DIP Switch Input 4
Understanding the functionality of the DIP switches is key to maximizing the versatility of the AAPHD Series. When a switch is in the
up position, the function is “OFF or assigned to the feature stated”; when a switch is in the down position, the function is “ON or
assigned to the feature stated“.
Switch A
• DP SW #1 - Input 4 Phantom Power 24VDC is active when Input 4 is set to Mic mode and the switch is in the ON
position. Note: Only use this feature if you are using condenser microphones, otherwise leave in the “OFF” position.
• DP SW #2 - Mute Receive Input 4 - When “ON”, Input 4 signal will be muted if a signal is present on Input 1 or if
the Remote Mute Terminals are shorted together.
• DP SW #3 - Zone 2 Assign Input 4 - When “ON”, Input 4 signal will be routed to the Zone 2 Output terminals. The
signal routed is PRE the front panel level controls.
• DP SW #4 - When in the “MIC” position, Input 4 will accept microphone level signals; when in the “Line” position, Input 1
will accept line level or telephone signals.
14. Input 5
Input 5 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
15. Input 6
Input 6 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
16. Multi Function DIP Switch Inputs 5 & 6 and Remote
Understanding the functionality of the DIP switches is key to maximizing the versatility of the AAPHD Series. When a switch is in the
up position, the function is “OFF or assigned to the feature stated”; when a switch is in the down position, the function is “ON or
assigned to the feature stated “.
Switch B
• DP SW #1 - Mute Receive Input 6 - When “ON”, Input 6 signal will be muted if a signal is present on Input 1 or if the
Remote Mute Terminals are shorted together.
• DP SW #2 - Mute Receive Input 5 - When “ON”, Input 5 signal will be muted if a signal is present on Input 1 or if the
Remote Mute Terminals are shorted together.
• DP SW #3 - Remote Level Port Assignment - Remote Level Port selection switch assigns the port to control Inputs 4, 5, and
6 or the Master Level. See Remote Level.
• DP SW #4 - Remote Input Select (RIS) - When “ON”, RIS terminals are active. When active, no input will be present at the
amplifier output unless the RIS input port pins are shorted to ground. See RIS ports.
17. Zone 2 Output Port
This terminal provides a 600Ω unbalanced output that is typically connected to a PBX music on hold port, also known as MOH. Inputs
are assigned to the Zone 2 bus via switch associated with the input. Note: 10kΩ output impedance is available via the internal shunt
selection.
