About the OSD XMP500DSP
Stout power output and precise DSP control
Stout power output and precise DSP control
OSD's XMP500DSP is a flexible powerhouse. It uses a highly efficient Class D amplifier to output a clean 250 watts per channel to your speakers. On top of that, there's an onboard DSP that maintains signal integrity, meaning the audio stays clear, dynamic, and accurate to the source.
A feature-packed front panel
The built-in screen on the front of the amplifier displays pertinent info, like the amp's status, menus, and DSP settings. There's a navigation control dial you can use to scroll through the various displays.The front panel also has buttons that let you choose which pair speakers you'd like to listen to. If you'd like, you can have both sets of speakers playing simultaneously by pressing both buttons in. There's also a volume knob and balance knob to help you better dial in the sound in your room or rooms.
"Main" and "local" source inputs
You'll find two RCA source inputs on the rear of the amplifier. You can hook up anything that uses an RCA connection, like a preamplifier, a smartphone (using a 3.5mm-to-RCA cable), or the like. Use the "main" input for the primary source you'd like to share between rooms. Its signal gets passed through a pair of RCA main outputs, for easy daisy-chaining to additional amplifiers. Use the secondary input for a "local" source. The amp automatically switches to your local source when it senses a signal. When it stops, the amp switches back to your main source.

Features
Stereo Amplifier: The OSD Audio XMP500DSP stereo amplifier incorporates class D amplification and DSP (digital signal processing) for clean and high efficient power with low distortion.
- Class D Amplfication: A Class D amplifier uses output transistors that are fully turned on or off during operation, so distortion is low while efficiency is high (93%). Class D amplification combine the best qualities of both class A and B technologies and are ideal for distributed audio because there is less heat to deal with and it can easily run two pair of loudspeakers.
- DSP (Digital Signal Processing): Digital Signal processing or DSP is a microprocessor chip that processes complex algorithms in less time. With DSP, the audio signal is modified digitally and converted to analog before sending it to the speakers. Amps designed in DSP have tighter control on output accuracy and can be more powerful than traditional analog components.
Stereo & Bridged-Mono Modes: The OSD Audio XM500DSP can be operated in Stereo mode or Bridged-Mono mode. The XMP500DSP 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: 250 watts x 2 channels (@ 1kHz with 1% THD and 100dB SNR)
- 4-Ohm Stereo Output: 350 watts x 2 channels (@ 1kHz with 1% THD and 100dB SNR)
- 8-Ohm Bridged-Mono Output: 700 watts x 1 channel (@ 1kHz 1% THD and 100dB SNR).
Audio Settings: The OSD Audio XM500DSP offers a variety of audio settings that can be used to tailor the amplifier's sound. You can choose between 10 preset EQ settings. There is also a Balance control and a Night Mode setting that limits the amplifier's dynamic range. You can store up to 3 audio settings memory presets that incorporate all these audio adjustments.
Analog Line-Level Inputs: The OSD Audio XMP500DSP 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 XMP500DSP 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 Outputs: The rear-panel stereo analog line-level RCA output allows the XMP500DSP's Main input signal to be passed through to another amplifier. The analog line-level output does not support the XMP500DSP's Interrupting input. There is also an analog mono-RCA output that allows you to connect a powered subwoofer (sold separately).
Speaker A & B Outputs: The OSD Audio XMP500DSP is outfitted with A & B speaker outputs. Thee A & B speaker outputs consists of 5-way binding post terminals that will accept bare-wire (up to 12AWG), pin-connectors, spade-lugs, 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.
Front-Panel LCD: A front-panel 16-character, 2-line LCD screen displays the amplifier's status, menus, and settings.
IR Remote: The included IR remote provides wireless operation of the OSD Audio XMP500DSP amplifier. Functions included Power On/Off, Volume Up/Down, Mute, Menu Navigation, Audio Settings and more.
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 XMP500DSP 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 XMP500DSP amp.
Auto Off: The XMP500DSP amplifier will automatically turn itself off after 5, 10, 15, 20, 25, or 30 minutes of no audio signal or operation.
Detachable AC Power Cord: The OSD Audio XMP500DSP comes with a detachable 6' IEC 3-prong AC power cord.
Rack Mountable: The OSD Aduio XMP500DSP includes mounting hardware to install the amplifier in an equipment rack.

Great sound, no frills, plenty of power. It runs pretty hot. I'm going to add a cooling fan to the rack.
