Resumen del manual
It is recommended to have the amplifier looked at by certified technician. 6. Balanced Input Connections Left and Right balanced input signals can be accomplished by wiring the removable Phoenix type connector per the labeling on the rear of the amp. Note: The middle pin is the common ground connection for both Left and Right input ground. For unbalanced signals connect the (–) and (GND) pins together. 7. Speaker Connections A removable Phoenix type connector is supplied to connect your speakers to the PA1001G. It is recommended to use 16guage wire or higher for connection to the speaker. Note: Do not overload the amp by connecting to many speakers to the amp. Four ohms per channel is the maximum load. 8. Four Position Dip Switch Assignment Switch 1 - Sense On/Off, this switch activates the PA1001G remote turn on sensing circuits via either Audio or AC trigger. When the switch is in the “DOWN” position, all trigger circuits are bypassed. The only way to turn the amp On or Off is via the mains AC Power Switch located on the front panel. When in the “UP” position either the Audio or AC Sense turn on Triggers is activated. See switch 2 for selection. Switch 2 - Sense AC / Audio, when Switch 1 is in the “UP” position you may select the type of remote turn on trigger. Note the AC Mains Power Switch must also be in the “on” position. AC Trigger - This switch function is used if you have an external device is plugged into the Unswitched AC outlet and you want that device to turn on or activate the amplifier. The “UP” position of Switch 2 is for AC trigger, meaning if a device such as a projector is plugged into the Unswitched AC outlet and is turned on the AC trigger circuitry will sense current draw and turn on the PA1001G. Note: To trigger the AC sense circuity you need a minimum of a 100mA of current draw to activate the PA1001G. Audio Trigger – This switch function is used if you have an external audio source plugged into either the RCA or Balanced inputs and you want that audio to turn on or activate the amplifier. If Switch 2 is in the “DOWN” position it is in Audio Sense mode. When audio is present at either the RCA or Balanced inputs, the trigger circuitry will turn on the PA1001G. See Audio Sense control below for sensitivity adjustments. Switch 3 – Line Out Pre - Post VCA - This switch function works in conjunction with the Line Out Jack and the Remote Level Control feature. This switch determines if the Line Out signal is fixed (Pre) or works with the Remote Level Control (Post). The “Down” position is Pre Remote Level, meaning the Remote Level does not affect the signal of the Line output and the “UP” position is Post or after the Remote Level Control, meaning the level will change with the Remote Level Control. Switch 4 – Hi Pass Filter In / Out, when this switch is in the “UP” position no input filter is applied. With the switch in the “Down” position a 100Hz 12db Hi-Pass filter is engaged at the input of each channel. 9. Audio Sense Trigger Adjustment This potentiometer works when Dip Switch 1 is set to “Down” or “sense on” position and Dip Switch 2 is in the “UP” or “audio” position. By rotating the potentiometer clockwise (right) the trigger point becomes less sensitive to turn on, meaning it will take more audio signal at the input to turn on the amp. Note: Once the PA1001G has sensed audio signal and has triggered on, it will take15 -20 min for it revert back into sleep mode even when there is no audio present. The PA1001G level controls have no affect on this feature. 10. Line Level Out This unbalanced RCA output allows you to feed the audio signal from the PA1001G amplifier to another amplifier. You can select to have a fixed signal or you can assign it to work with the Remoter Level Control. See Line Out Function Switch for settings. 11. Remote Level Control VCA Remote location of the level control can be accomplished via the VCA control port. Connect the two leads from the optional remote volume control to these terminals. Set the system's maximum levels using the amplifier level controls and then use the remote VCA potentiometer as an attenuator from the maximum levels set. WIRING THE AAVCC-10K VCA POTENTIOMETER – Atlas part number, AAVCC-10K, consists of a single gang "Decora" style wall plate with a pre-mounted 10K potentiometer and knob. Use two conductor unshielded wire connecting the plot terminals marked "VCA" on the back of the amp. INSTALLATION and CONSIDERATIONS Cabling: The PA1001G can be used with either balanced or unbalanced sources, and the outputs can be used with either balanced or unbalanced loads, provided the proper cabling is used. A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground. An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential. Balanced Input - Use 2 conduct...
