      "acceptedAnswer": {
        "@type": "Answer",
        "text": "It is a compact Class D audio amplifier with two stereo line inputs and one balanced microphone input. It combines amplification, microphone mixing, EQ, and remote control for small commercial AV systems."

      "@type": "Question",
      "name": "What output power does it provide?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "It delivers 2 x 20W at 4 ohms, 2 x 10W at 8 ohms, or 1 x 40W at 8 ohms in bridge mode. The selectable output arrangements allow the amplifier to match different speaker configurations."

      "name": "How many inputs does it have?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "It provides two stereo line inputs and one microphone input. The microphone channel can be mixed with program audio for presentation and conferencing applications."
      }

    {
      "@type": "Question",
      "name": "Does it support phantom power?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, the microphone input supports 48V phantom power as well as dynamic and wireless microphones. This allows the amplifier to work with different microphone types in professional AV installations."
      }
    },
    {
      "@type": "Question",
      "name": "Can it mix microphone and line audio?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, the microphone can be mixed with line audio and the sources can be controlled separately. This is useful when speech must remain intelligible over presentation or background audio."
      }
    },
    {
      "@type": "Question",
      "name": "Does it support bridge mode?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, bridge mode provides up to 40W into an 8-ohm load. Bridge mode is useful when one higher-power speaker channel is required instead of two independent outputs."
      }
    },
    {
      "@type": "Question",
      "name": "Can it be remotely controlled?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, volume and tone functions can be controlled from the front panel, IR remote, and RS-232. Remote control makes it suitable for integrated room-control systems."
      }

      "@type": "Question",
      "name": "Does it provide mono mixing?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, a mono-mix function can sum left and right program channels for mono output. This is useful for distributed speaker systems where a single mono program is preferred."
      }

      "@type": "Question",
      "name": "Is it fanless?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, the amplifier uses a fanless design. The absence of a cooling fan helps minimize mechanical noise in classrooms and meeting rooms."

    {
      "@type": "Question",
      "name": "Where is it used?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "It is suitable for classrooms, meeting rooms, boardrooms, sports bars, and similar commercial AV spaces. Its compact form and flexible audio routing make it useful for small integrated sound systems."
