Frequently Asked Questions
What sources can be played through the CMX EA-120 Mixer Amplifier?
The CMX EA-120 includes a built-in digital multimedia player supporting wireless Bluetooth streaming from smartphones and laptops, MP3 audio playback from USB drives and SD cards, and a digital FM radio tuner. It also provides two rear auxiliary RCA inputs for external media players, CD decks, or streamers.
Can the EA-120 drive both ceiling speakers and low-impedance wall speakers?
Yes. The amplifier is equipped with multi-tap speaker output terminals supporting 100V and 70V high-impedance commercial distributed speaker lines (for multiple ceiling or wall speakers with transformers), as well as direct 4-Ohm, 8-Ohm, and 16-Ohm low-impedance loudspeaker loads.
How does the VOX microphone priority work on the EA-120?
The primary Mic 1 input features voice-activated (VOX) priority. When an operator speaks into the microphone connected to Mic 1, the amplifier automatically ducks (attenuates) any background music playing from Bluetooth, USB, or Aux inputs, restoring full volume once the announcement ends.
Can the EA-120 operate during an electrical power outage?
Yes. The unit features dual-power capability, operating on standard 230V AC mains as well as an external 24V DC battery backup power terminal, ensuring critical paging and announcements remain active during power failures.
What is the Telephone Paging and Music On Hold (MOH) function?
The telephone paging terminal connects directly to an office PBX or VoIP phone system, allowing staff to make announcements through their desk phones. The MOH output feeds audio from the amplifier back into the phone system so callers on hold hear pleasant background music.
