MAGNETIC FIELD: !!CAUTION!!
Do not locate sensitive high-gain equipment such as p r eampliﬁers 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 p r eampliﬁer or other sensitive equipment at the top.

FRONT & REAR PANEL CONTROLS

OSD-AUDIO-XMP300-2-Channel-150W-Class-D-Amplifier-
FIG-2

Power Switch
Switches the XMP300 on or o f f. A red LED indicates connection to AC power while in standby mode. Turns green indicating audio signal is present.
Speaker Selector
Selects speaker zone A or B. For A + B zones push both buttons in.
Balance
Fades speaker output between the Right and Left Channels
Volume
Adjusts ampliﬁer volume.
1. Bass and Treble Controls
  These controls can adjust bass and treble frequencies +/- 12dB at 100Hz and 10kHz.
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.
Main Input/Output
MAIN IN should be used as the “primary” or main input for the ampliﬁer. Connect your receiver or main source to this input. Use MAIN OUT to pass MAIN IN signal to another amplifier.
12V Trigger
Allows the XMP300 to be powered on by other electronics or to power on other electronics via a 3.5mm mini phone plug cable.
Mode Select Switch
Switches the ampliﬁer from Stereo mode to Bridged mode.
- STEREO MODE
  If you will be connecting one or two pair of speakers to the ampliﬁer, place the switch in the “Stereo” position. NOTE: For playing 2 pairs of speakers (A plus B), make sure each speaker has an impedance of 8 ohms or greater.
- 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 XMP300 supplies 450W in bridged mode, Please verify that your speakers are capable of handling such power to avoid possible damage!
AUTO ON Select Switch
Power can be turned on and off manually via the switch on the front pane l 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 ower switch must be in the ON position (pushed in) for the AUTO ON feature to operate.
Speaker Zone A Output Figu r e 2. Rear Panel Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged or 4 ohm stereo.
Speaker Zone B Output
Speaker output terminals for zone B. Minimum impedance: 8 ohm bridged or 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 one zone (A or B) can be bridged. Do not attempt to bridge both
  A and B speaker terminals! This may result in a lower impedance than the ampliﬁer is designed for and may damage your ampliﬁer. The minimum impedance for the total load connected in bridged mode is 8 ohms.
  NOTE: Use Class 2 wiring 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 the binding post by twisting clockwise 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 amplifiers. 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.
  50’ or less – 16 Gauge 2-Cond. CL3 Rated 50’ – 150’ – 12 Gauge 2-Cond. CL3 Rated 150’ – 200’ – 10 Gauge 2-Cond. CL3 Rated
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 XMP300. 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 XMP300 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 XMP300 as a local zone ampliﬁer via the MAIN inputs. Normally the distributed audio system will be the audio source for the XMP300 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 XMP300 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 s ignal will still be present at the MAIN input. In this circumstance the audio output of the local source will be heard via the XMP300. Once the local source is turned off or muted, the XMP300 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.
