CMX EA-30T – 2 Zone Mixer Amplifier
Professional Compact 30W RMS 2-Zone Commercial Mixer Amplifier with Built-In Bluetooth, USB/SD MP3 Player, FM Tuner, Dual 100V Speaker Zones with Independent Zone Attenuators, VOX Priority & 24V DC Backup
The CMX EA-30T is a compact 30W RMS 2-zone commercial mixer amplifier engineered specifically for small-to-medium multi-room public address (PA) and background music (BGM) installations. Equipped with two discrete 100V speaker zones featuring individual front-panel zone attenuators, it allows venue managers to route and independently balance audio across separate areas—such as boutique dining rooms and outdoor patios, retail shopfronts and stockrooms, or doctor clinics and reception lobbies. The unit integrates a full-featured digital media player supporting Bluetooth wireless streaming, USB flash drive and SD card MP3 playback, FM radio, and an IR remote control. With balanced XLR Mic 1 featuring switchable 48V phantom power, voice-activated VOX priority override, dedicated telephone paging with Music-on-Hold (MOH), and flexible 230V AC / 24V DC dual-power redundancy, the EA-30T is the ideal multi-zone audio solution for modern commercial venues.

Frequently Asked Questions
What is the key benefit of the CMX EA-30T over a single-zone amplifier?
The EA-30T provides two independent 100V speaker zones with separate zone attenuators on the front panel. This enables facility operators to power and independently adjust sound levels across two distinct areas (e.g. indoor dining vs. outdoor patio, or customer showroom vs. back office) from a single compact unit.
What is the recommended speaker load for the EA-30T across two zones?
With a 30W RMS rating 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 distributed across Zone 1 and Zone 2.
Can the EA-30T operate on 24V DC battery backup during power outages?
Yes. The EA-30T features a dual power supply system supporting both standard 230V AC mains and a 24V DC battery connection, guaranteeing continuous emergency paging and public address operation during electrical power failure.
Does the EA-30T support commercial condenser paging microphones?
Yes. The Mic 1 input features a balanced XLR connection with a dipswitch for 48V phantom power, enabling direct connection with professional condenser gooseneck paging microphones as well as standard dynamic microphones.
How does the VOX priority override work on the EA-30T?
When speech audio is detected on the balanced Mic 1 input, the automatic VOX priority circuit instantly mutes or attenuates background music playing from Bluetooth, USB, SD, or RCA Aux inputs. Once the paging announcement finishes, background music smoothly returns to its previous level.
