The new professional audio series from Eurodynamic aims to prove that high-quality construction, clear sound, and reliability can come at an affordable price.

By using the best materials and attention to detail, it provides everything needed for both the producer to create sound and the listener seeking an enjoyable auditory experience.

The AMS4 is a 4-channel mixer with 2 microphone preamps and a built-in sound card.

Features:

• 2 Microphone Preamps with 48V Phantom Power and 1 stereo channel.
• Each channel includes a mute switch, 2-band Low/High equalizer, Gain control, FX level, and volume knob.
• The stereo channel features a switch to control either the volume of the stereo input (via RCA or mini jack 1/8″) or the volume of a connected USB device.

The built-in FX unit with 32-bit DSP effects offers 99 different programs, controlled via a display and navigation buttons. Adjacent to this is a control display for the USB unit’s player.

Using the USB output of the mixer with a computer, you can record anything connected to the mixer with a sampling quality of 16-bit/44.1kHz.

It also includes a Bluetooth receiver for streaming audio, a USB input for MP3 file playback, and a dual monitor level with 8 LED indicators.

The mixer’s output supports connections via TS Jack or Balanced XLR, delivering clear, noise-free sound under any conditions.
