  • Page 3: Preface

    Save all packaging in a dry place away from fire hazards. Your Pallene is a precision electronic instrument and should be properly packaged any time shipment is made. In the unlikely event that you have to return your Pallene to the factory for service, or if you send it to us for updating, the original packaging will best protect the unit from shipping damage.
  • Page 4: Safety Precautions

    BEFORE MAKING ANY CONNECTIONS TO THE PALLENE, FIRST TURN OFF THE POWER AND THEN DISCONNECT THE AC POWER CORD. WHEN INSTALLING THE PALLENE IN YOUR SYSTEM, MAKE CERTAIN TO ALLOW A MINIMUM OF 4 INCHES OF VENTILATION ON EACH SIDE OF THE UNIT. ALSO ALLOW AT LEAST 6 INCHES OF VENTILATION SPACE ABOVE THE UNIT.

    11. DB9 RS232 connector. Used for connecting a system control device to the Pallene to control and monitor its functions. 12. Remote Trigger jack. If the rear panel trigger jack receives a 5-12VDC signal, the Pallene will come out of standby if the Main Power switch is in the On position.
  • Page 8: Wiring Diagram

    The Pallene may be plugged directly into an un-switched wall outlet. Although proprietary RFI (radio-frequency interference) filtering is built into the Pallene, in some situations an AC power-line filter may provide additional sonic benefits. A power-line conditioner with spike and brownout features is recommended.
  • Page 9: Initial Setup

    A positive pulse that is greater than 100mS is interpreted as a Level trigger whereas shorter pulses are treated as Pulse triggers. The minimum detectable pulse is 50uS. When a Level type signal is received, the Pallene will be taken out of standby and when that signal drops to zero, the Pallene will go into standby.

    L104 In this example, L1 refers to Light Level 1. 04 is the current ambient light level the Pallene is reading in the room. XX is the value the user can change the display brightness to when the Pallene reads the room light level at 1. As the desired value is edited, the display brightness changes to show the user how bright or dim the current setting will be.
  • Page 15: Setup Input

    Input Level The factory default is 0. Line level sources may have different output levels. To streamline this, the Pallene allows the user to adjust any Input level to match that of other sources. The range is –12 to + 12.
