Frequently Asked Questions
What is the recommended speaker load for the CMX EA-30?
With a rated 30W RMS continuous power output and standard 20% engineering headroom (recommending up to ~24W total speaker load), you can connect four to six 3W or 4W ceiling speakers, or three to four 6W ceiling speakers tapped on the 100V line, making it perfect for small retail stores, cafes, and offices.
Can the EA-30 operate on 24V DC battery backup during power outages?
Yes. The EA-30 features dual-power capability supporting standard 230V AC mains and an emergency 24V DC battery connection, ensuring uninterrupted voice paging and audio during power cuts.
Does the EA-30 support condenser paging microphones?
Yes. The Mic 1 input features a balanced XLR connector with a dipswitch for 48V phantom power, enabling direct connection with professional gooseneck condenser microphones as well as dynamic microphones.
How does the VOX priority override work?
When an announcement is made through the primary balanced XLR Mic 1 input, the automatic VOX voice-activated circuit immediately lowers background music playing from Bluetooth, USB, SD, or RCA Aux inputs. Once speaking ceases, background music smoothly fades back to normal volume.
Can I stream audio wirelessly from a smartphone or tablet?
Yes. The built-in media player includes wireless Bluetooth connectivity, allowing you to easily stream music, podcasts, or online radio directly from any smartphone, tablet, or laptop.
