    RISK OF ELECTRIC SHOCK
    • This lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of non-insulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
    • 
      To reduce the risk of electric shock, do not remove cover (or back) as there are no user-serviceable parts inside. Refer servicing to qualified personnel.
    • The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying the appliance.

MAGNETIC FIELD:

Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Because this amplifier has a high power density, it has a strong magnetic field, which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit. If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier or other sensitive equipment at the top.

FRONT PANEL CONTROLS

1. Power Switch
   Switches the XMP100 on or off. A red LED indicates connection to AC power while in standby mode. Turns green indicating audio signal is present.
2. Speaker Selector
   Selects speaker zone A or B. For A + B zones push both buttons in.
3. Balance
   Fades speaker output between the Right and Left Channels
4. Volume
   Adjusts amplifier volume.

REAR PANEL CONTROLS

6. Bass and Treble Controls
   These controls can adjust bass and treble frequencies +/- 12dB at 100Hz and 10kHz.
7. Interupting Line Input
   This is the secondary input, use MAIN IN for your main input. INTERRUPTING INPUT can be used if a second source is desired and takes over when signal is present and has at least a 5mV level. When there is no signal, or a signal with less than 5mV level, the amp switches back to MAIN IN after a brief delay.
8. Main Input/Output
   MAIN IN should be used as the "primary" or main input for the a mplifier. Connect your receiver or main source to this input. Main out only plays whatever is connected to Main In. It will not play the signal from the Interrupting Input. Use Main out to connect to another Amplifier or to Powered Sub-woofer.
9. 12V Trigger In/Out
   Allows the XMP100 to be powered on by other electronics or to power on other electronics via a 3.5mm mini phone plug cable.
10. Mode Select Switch
    Stereo Mode (4-8 ohms) to Bridge Mode (Speaker A only, 8-ohm minimum) BRIDGED MODE When set to "Bridged" mode, the amplifier is a single channel mono amplifier BRIDGED MODE- MONO APPLICATION For bridged mode, playing Right and Left together as mono output, plug RCA cables in to Right and Left RCA at MAIN input. Set the MODE switch to BRIDGED and follow the instructions for bridged speaker connection in the SPEAKER TERMINALS section of this manual.
    NOTE: The XMP100 supplies 160W in bridged mode, Please verify that your speakers are capable of handling such power to avoid possible damage.
11. AUTO ON Select Switch
    Power can be turned on and off manually via the switch on the front panel or automatically by signal sensing. Set it to NORMAL for manual power on/off. Set to AUTO for signal sensing; the amp will turn on when audio signal is detected at the inputs.
    NOTE: The front panel power switch must be in the ON position (pushed in) for the AUTO ON feature to operate.
12. Speaker Zone A Output
    Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged or 4 ohm stereo.
13. Speaker Zone B Output
    Speaker Output Terminal for zone B. Minimum Impedance; 4-ohm Stereo
    SPEAKER TERMINALS - STEREO MODE
    For stereo output connect the speaker's positive (red) terminal to the amplifier's positive (red) terminal, and the speaker's negative (black) terminal to the amplifier's negative (black) terminal for each Right and Left speaker.
    SPEAKER TERMINALS - BRIDGED MODE
    Place the "MODE" switch in the "BRIDGED" position and use both red terminals to connect to the speaker. Connect the speaker's positive (red) terminal to the amplifier's red (+) terminal noted next to the bridging mark, and the speaker's negative (black) terminal to the amplifier's unmarked positive (red) terminal.
    NOTE: Only Speaker A can be used for bridged Mono as labeled on the back panel. Do not attempt to Bridge both Speaker A and Speaker B! This may result in damage to the amplifier. The minimum Impedance for a single bridged connection is 8 ohm.
    NOTE: Use Class 2 wiring for residential in-wall or Class 3 for residential and most commercial installations for speaker connections. To wire the output connector:
    1. Strip the insulation off each speaker wire to expose 3/8" (10 mm) of bare conductor.
    2. Unscrew the output terminal binding post several twists, insert each wire into the correct terminal.
    3. Tighten binding post by twisting clock-wise until it is firmly clamping the speaker wire. Warning: While the amplifier does self-protect under most improper output conditions, misconfiguration of loudspeaker mode and incorrect connection of loudspeakers could damage connected loudspeakers and/or amplifier. Please refer installation to a qualified installation professional, and always check state and local electrical codes when installing.
       NOTE: To prevent sonic degradation in your speaker installation, total speaker wire resistance should be kept below 0.5 ohms. This table lists recommended speaker wire gauge versus wire run length.
       • 0-80 ft - 16 Gauge 2/4 conductor CL3 Rated
       • 81ft to 200 ft - 14 Gauge 2/4 Conductor CL3 Rated
       • 200 Plus Ft -12 gauge 2 Conductor CL3 Rated
14. Power Cord
    This amplifier is configured for operation at 115V (North America). A fuse located internally protection from fault conditions. Refer to qualified service personel should this need to be replaced.

APPLICATIONS

STEREO SETUP

In this configuration, the mode switch is set to "Stereo". Connect the line out jacks from a stereo pre-amplifier or source to the MAIN input jacks of your XMP100. Next connect your speakers to the terminals marked "Speaker A" observing proper polarity. Select the "A" speakers using the front panel zone selection buttons. Connect a second (optional) pair of speakers to the terminals marked

"Speaker B". If you are connecting 4 speakers to the XMP100 they must be 8 ohm speakers only. Press A and B together to use both zones.

SETUP FOR MULTIPLE SOURCE

In the multiple source set up, a distributed audio system is connected to the XMP100 as a local zone amplifier via the MAIN inputs. Normally the distributed audio system will be the audio source for the XMP100 The distributed audio is then passed on to be used by additional zones or sub zones in the distributed system via the MAIN outputs.

The audio output of a local source, such as an MP3 Player, CD, television, computer, etc., is connected to the XMP100 via the INTERRUPTING inputs, and whenever the local source is active its signal will take priority over the distributed audio signal present at MAIN input. However, the distributed audio signal will still be present at the MAIN input. In this circumstance the audio output of the local source will be heard via the XMP100. Once the local source is turned off or muted, the XMP100 will automatically switch back to the distributed audio system as an audio source, assuming the local source remains inactive. There is a delay of up to 6 seconds when switching from INTERRUPTING input back to MAIN inputs.
