Features
Class D Stereo Amplifier: The OSD Audio XMP100BT (GEN2) stereo amplifier incorporates class D amplification for clean and high efficient power with low distortion. It can be operated in Stereo mode or Bridged-Mono mode. The XMP100BT amplifier can handle 8- or 4-ohm impedance loads in Stereo mode, as well as an 8-ohm impedance load in Bridged-Mono mode.
- 8-Ohm Stereo Output: 50 watts x 2 channels
- 4-Ohm Stereo Output: 100 watts x 2 channels
- 8-Ohm Bridged-Mono Output: 200 watts x 1 channel
Analog Line-Level Inputs: The OSD Audio XMP100BT class D amplifier is outfitted with two sets of stereo analog line-level RCA inputs. There is a Main stereo RCA input and a Interrupting Stereo RCA input. When an audio signal is present at the Interrupting Stereo RCA input, then the XMP100BT will automatically switch from the Main input to the Interrupting input. There is approximately a 6 second delay when switching between the Interrupting input and the Main input.
Analog Line-Level Output: The rear-panel stereo analog line-level RCA output allows the XMP100BT's Main input signal to be passed through to another amplifier. The analog line-level output does not support the XMP100BT's Interrupting input.
Speaker A & B Outputs: The OSD Audio XMP100BT is outfitted with A & B speaker outputs. The A & B speaker outputs consists of binding post terminals that will accept bare-wire (up to 12AWG), pin-connectors, and banana plugs (single or dual). In Stereo mode, you can connect one pair of 4-ohm loudspeakers or two pair of 8-ohm loudspeakers. In Bridged-Mono mode, you can only connect a single 8-ohm loudspeaker to either the A or B speaker outputs, but not both.
- You can select output from Speaker A only, Speaker B only, or select output from both Speaker A and Speaker B.
- When using both the A & B speaker outputs, the same audio source will be played back in both zones.
Bluetooth Connectivity: The XMP100BT amplifier features built-in Bluetooth (v. 5.3) for wireless audio streaming from your connected Bluetooth audio device. A rear panel Pairing button and a front panel Pairing/Status button let you easily pair your Bluetooth audio device to the amplifier.
USB: A USB-A port on the rear panel of the OSD amplifier lets you play back stored audio from a flash drive in resolutions up to 24-bit/192 kHz.
Tone & Balance Controls: The OSD Audio XMP100BT amplifier offers Bass (100Hz) & Treble 10kHz), as well as Balance (L/R) control. The Bass & Treble control knobs are located on the rear-panel and can be adjusted between -12 and +12 dB. The Balance control knob is located on the front-panel.
12V Trigger In/Out: There is a 12V trigger input (3.5mm) and output (3.5mm) on the back of the OSD Audio amplifier. The 12V trigger input allows the XMP100BT to be powered on by the 12V trigger output of another electronic component. The 12V trigger output lets you power on another electronic component that features a 12V trigger input from the XMP100BT amp.
AC Power Cord: The OSD Audio XMP100BT includes a 59" AC power cord that will need to be plugged into an AC wall outlet or surge protector (sold separately).
Mounting: The XMP100BT includes removable rubber feet for placing the amp on a shelf or table-top. Two rack ears are also included for mounting the amp in a standard 19" equipment rack. When rack-mounted, the XMP100BT takes up 1U of space.
The OSD XMP100BT GEN2 replaces these items:
- outputs for two pairs of speakers
- 50 watts per channel at 8 ohms
- dual RCA stereo inputs for connecting two separate sources

This amp does a terrific job of helping produce a warm, rich sound from old Polk speakers embedded in our ceilings in two rooms. Super easy to connect/use but sounds better streaming through our old AirPort Express than through the unit's Bluetooth. Highly recommend
