Simplify the task of running distributed audio for restaurants, hotels, or anywhere large areas need background music and/or paging address systems.
For example, if you want to connect two speakers per channel in a traditional 8‑ohm speaker system, you must either connect them in series, which results in an overall 16‑ohm impedance, or in parallel, which results in an overall 4‑ohm impedance. This reduces power loss during transmission, which allows for the use of longer speaker wire runs using smaller gauge wire. Adding a third speaker to the mix would complicate it further, producing either a 24‑ohm or 2‑ohm overall impedance.Features: 5‑channel (3 microphone and 2 line) mixer/amplifierAmplifier rated for 120 watts70V, 100V, and low impedance 4~16 ohm speaker output optionsBuilt‑in rack mount ears and 2U height for mounting in a standard 19" equipment rackUnbalanced front panel input for MIC 1Both balanced XLR and unbalanced TRS and RCA rear panel inputs for MIC 2 and MIC 3Phantom power option for MIC 2 and MIC 3Two unbalanced RCA auxiliary/line inputsOne EMC priority inputMaster volume, bass, and treble controlsFront panel level controls for all inputs0‑30dB variable muting for all channels except MIC 1 when MIC 1 is in useBuilt‑in short circuit, over‑current, and high temperature protection circuitsLine level output of mixed signal for connection to other devices In the first case, the 16‑ohms impedance effectively halves the output power of your amplifier, resulting in lower overall volume levels.
