13. Pre Out
The PRE OUT RCA port is POST the preamp mix bus but PRE the Master Level. This feature is used in two applications.
A. Effects loop - Used in conjunction with the AMP IN connector, an effects loop can be created by connecting the PRE OUT
jack to a device such as an equalizer or DSP and then back out to the AMP IN connector.
B. Second Amplifier - If the amplifier output power is not enough, the mixer amp can be used as a preamp to feed a second
amplifier of choice. Note: The Master level will not be functional for the application.
14. Amp In
The AMP IN connector is useful for converting the AAPHD into a slave amp. When a line level signal is connected to this input, the
internal connection between the preamp and internal power amp is broken. Audio signals applied to this connector are POST tone
control and input level controls. The Master Level will function.
15. Multi Function DIP switch
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 " .

DP SW #6 - Mute Receive Input 3 - When "ON" , Input 3 signals will be muted if a signal is present on Input 1 or if the
Remote Mute Terminals are shorted together.

Note: Only use this feature if you are using condenser microphones, otherwise leave in the "OFF" position.
•
DP SW #9 - When in the "MIC" position, Input 1 will accept microphone level signals; when in the "Line" position, Input 1 will
accept line level or telephone signals.
•
DP SW #10 - Remote Level Port selection switch assigns the port to control Inputs 2, 3, and 4 or the Master Level.
•
DP SW #11 - RIS (Remote Input Select) activates the RIS terminals when in the ON position. When the RIS is active, NO input
will be present at the amplifier output unless the RIS input port pins are shorted to ground. See RIS ports.
