Zoom AMS-44 4-In/4-Out XLR/TRS Audio Interface
Whether you’re recording or streaming, the AMS-44 keeps your setup simple. It features four XLR/TRS combo inputs along with Zoom’s high-performance, low-noise preamps. The interface also includes two headphone outputs and two TRS outputs for external monitors.
With their onboard hardware switches, the AMS-24 and AMS-44 are designed to simplify common streaming challenges without the need for additional software.
Toggle from recording to livestreaming with the Music/ Streaming Switch. When in Music mode, each input acts independently with individual gain control. It also sends separate mixes to each headphone output.
When in Streaming mode all inputs are combined into one signal to work seamlessly with your streaming software.
Use the Direct Monitor Switch to send the input signal directly to your headphones while routing the same signal to your DAW or streaming software.
The Loopback Switch combines the input audio with playback from your computer and routes it to your streaming software. This is perfect for adding background music to your stream or singing live with an instrumental track.
