10. Power Sources – The appliance should be connected to a power supply only of the type described in the operation instructions or as marked on the appliance.

11. Grounding or Polarization – Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third grounding prong are provide for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

12. Power-Cord Protection – Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cord at plugs, convenience receptacles, and the point where they exit from the appliance.

13. Cleaning – Clean only with dry cloth.

14. Power Lines – An outdoor antenna should be located away from the power lines.

15. Nonuse Periods – The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.

16. Accessories – Only use attachments/accessories specified by the manufacturer.

17. Object and Liquid Entry – Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

18. Damage Requiring Service – The appliance should be serviced by qualified service Personnel when:
    A. The Power-supply cord or the plug has been damaged; or
    B. Objects have fallen, or liquid has spilled into the appliance; or
    C. The appliance has been exposed to rain; or
    D. The appliance does not appear to operate normally or exhibits a marked change in performance; or
    E. The appliance has been dropped, or the enclosure damaged.

REFERENCE INFORMATION

The following information is provided for reference only. Please consult a professional if unsure about any aspects of commercial or residential installations.
Speaker Connection
The rear panel of the amplifier contains 2 Line Outputs (Line 1 and Line 2). BE SURE TO CONNECT SPEAKERS PROPERLY, see line voltage instructions below. The speaker lines are to be connected directly between the appropriate COM terminal on the terminal strip and the terminal corresponding to the impedance of the speaker(s). Connect the cables to the terminals on the screw terminal strip provided. Use the screw terminals which correspond to the proper polarity of the speaker(s). One lead must always be connected to the COM.
IMPORTANT NOTICE: When 70V constant line voltages are used, a line matching transformer must be used with each speaker. All transformers must be connected in parallel.
ALWAYS CONNECT LINE TRANSFORMERS IN PARALLEL, NEVER CONNECT IN SERIES
Speaker Impedances
Speaker terminal taps for 70V constant line voltage are provided on the rear panel of the unit. To connect the power output directly to a speaker or PA horn or a combination of speakers and/or PA horns, connect to the COM and (+) terminal on the strip. Be sure the speaker(s) or PA horn(s) can handle a reasonable power output from the amplifier or permanent damage to the speaker(s) or PA horn(s) may result. Also, be careful not to overload the amplifier with too many speakers or PA horns. If it is desired to use a number and variety of speakers, the speakers must be arranged in various series or parallel arrays to provide proper impedance matching. 70V constant line voltage must be used (parallel connection only). If you are not familiar with impedance matching, consult a professional installer or technician for advice. If 70V constant line voltages are used, a line matching transformer must be used with each speaker. Again do not overload or use incompatible speakers. Line transformers are the preferred method for multi-speaker installation.
Cable Requirements
Output cabling need not be shield in most case and should be of sufficient gauge to minimize losses due to the resistance of the wire over long runs (insertion loss). Cable thinner than 18 gauge AWG is not recommended.
Long runs require 16 gauge AWG or heavier.
In some cases where the output cable is run in close proximity to unshielded intercom cables, electrical cables, radio transmission antennas or other sources of interference, or when the amplifier is being used for paging from a telephone system, the amplifier may require shielded output cabling to prevent audio feedback or interference.
WHENEVER IN DOUBT ABOUT INSTALLATION, CONSULT WITH A PROFESSIONAL INSTALLER OR TECHNICIAN. OTHERWISE, PERSONAL INJURY, DAMAGE TO THIS AMPLIFIER AND/OR SPEAKERS MAY RESULT AND YOUR WARRANTY MAY BE VOID.

FEATURES AND FUNCTION

Rack Mounting
The XPA-1000/600 both come with Rack Mounts in the box. Remove the two chassis screws from each side panel, closest to the front panel Attach the rack-mount ears to the sides of the front face plate using the screws that come with the rack mounts (2 each side). The amplifier will occupy 1U of rack space. Ensure that the unit is in a well-ventilated area that provides adequate cooling. Free air space is required above the amplifier and below the amplifier. The recommended distance is 1U to 2U, 1.75” to 3.5” being sure to avoid blocking any vents on the unit’s chassis. Bottom feet on the amplifier chassis may be removed if necessary.
NOTE: Do not place the screws back into the chassis. Without the feet, the length of the screw may touch internal components and affect the performance of the amplifier.
Balanced Input
Use the BALANCED INPUT to connect balanced or unbalanced cables to the amplifier.
NOTE: The unbalanced connection needs a jumper from the Shield to the Negative. The unbalanced connection is used when there is no balanced source and more additional connections to the amp are needed.
Balanced Input
Use the BALANCED INPUT to connect balanced or unbalanced cables to the amplifier.
NOTE: The unbalanced connection needs a jumper from the Shield to the Negative. The unbalanced connection is used when there is no balanced source and more additional connections to the amp are needed. Unbalanced Connections
Use standard RCA cables to connect sources using the UNBALANCED LINE IN input. Connect sources through the applicable mono input. Use the LOOP OUT ports to connect more amplifiers or equipment. Using Fixed Loop Out
The LOOP OUT connections on the amplifier may be used to send audio signals to other equipment, or to the other channel of the amplifier. This connection sends audio signals out from the UNBALANCED INPUT of the channel. Single Source W/ Stereo Output Two Source W/ Two Mono Output Zones Single Mono Source Unbalanced XPA IR Remote
The XPA-1000 and XPA-600 IR Remote Controller, controls the individual zones on our PAM-1270 amplifier. It can also be used to teach IR commands to a programmable, integrated universal IR Remote, zone control system or other IR routing device.
Both of the XPA-1000 and the XPA-600 come with a IR Receiver module that connects to the IR two conductor input connector. There is no built in IR Sensor. The following are brief descriptions of each button. Universal IR codes are also available on the next page of the Owners Manual.

IR Remote Function

1. IR LED – One, high-output IR LED. The IR LED flashes invisible (infrared light pulses that are the control codes for the XPA-1000 & XPA-600. The LED must be pointed at an IR receiver that is connected to an XPA-1000/600. The IR Receiver Sensor must be connected to the IR 2 Conductor Connector
2. Power On/Off– Separate Power On (Red Button) and Power Off.
3. Source Selects between the Unbalanced and Balanced Sources.
4. Ch1 Vol+, Vol- & Mute – CH1-Unbalanced/CH3-Balanced; Volume Up. CH1-Unbalanced/CH3-Balanced and Mute for CH1 and CH3.
5. Ch2 Vol+, Vol- & Mute – CH2-Unbalanced/CH4-Balanced; Volume Up. CH2-Unbalanced/CH4-Balanced and Mute for CH2 and CH4.
6. All Channels Vol+, Vol- & Mute – All Channels-Unbalanced/ Balanced; Volume Up. All Channels-Unbalanced/Balanced and Mute for All Channels.

XPA IR Remote Universal Codes
The XPA 70V Amplifiers IR Remote Controller, controls the individual Power On/Off, Source, and the Volume Levels for Channels 1/3 & 2/4 and All Channels combined. It can also be used to teach IR commands to a programmable, integrated universal IR Remote or other IR routing device. The following are the Remote Controller Head  Code and Hex codes for the individual buttons: XPA1000/XPA600 Remote Controller Head Code: 00FF
