Frequently Asked Questions
What is the key difference between the CMX EA-120 and the CMX EA-120A?
While both models deliver 120W RMS power with integrated Bluetooth, USB, SD, and FM playback, the EA-120 is a compact tabletop unit, whereas the EA-120A is built in a standardized 19-inch 2U rack-mount chassis with reinforced dual front handles and a deeper 405mm chassis for permanent installation in commercial AV equipment racks.
Can the EA-120A power both 100V ceiling speakers and low-impedance wall speakers?
Yes. The EA-120A features multi-tap output terminals for 100V and 70V commercial distributed speaker lines (allowing many ceiling or horn speakers to be connected in parallel), as well as direct 4-Ohm, 8-Ohm, and 16-Ohm low-impedance connections for foreground hi-fi sound.
How does the VOX microphone priority override operate on the EA-120A?
The primary Mic 1 balanced XLR input features voice-activated (VOX) priority. When an announcement is spoken into Mic 1, the amplifier automatically mutes or lowers background music playing from Bluetooth, USB, or Aux inputs. Once speaking stops, the background audio smoothly returns to normal volume.
Does Mic 1 support professional condenser microphones?
Yes. Mic 1 includes switchable 48V phantom power, allowing commercial gooseneck condenser microphones or standard dynamic microphones to be plugged in directly via balanced XLR.
What protection systems are built into the CMX EA-120A?
The EA-120A includes comprehensive protection against output short-circuits, signal clipping distortion, overload, and thermal overheating, backed by visual front-panel LED indicators to prevent damage to connected loudspeakers.
