JBL Professional VMA1240 - 240W 5x1 Commercial Mixer/Amplifier with Bluetooth, USB and 70/100V or 4/8Ω Outputs
The JBL VMA1240 is a professional mixer/amplifier designed for commercial audio installations requiring ease of use and reliability. It features five independently controlled inputs and one 240W output , compatible with both low impedance (4/8 Ω) and constant voltage (70/100V) networks. It includes a built-in media player with Bluetooth and USB for MP3 playback, and paging features such as announcement chime , priority muting , and VOX ducking , all housed in a compact 19"/2U rack-ready chassis.
Its architecture combines balanced mic/line inputs (Euroblock/TRS) and RCA inputs for music, with per-output bass and treble equalization (±14 dB). Electrically, it offers a frequency response of 20 Hz–20 kHz into 4/8 Ω and 80 Hz–15 kHz into 70/100 V, THD < 0.5% , SNR > 76 dB , and crosstalk −70 dB . It is compatible with the JBL CSR-V remote volume control (RJ45/CAT5) and features 27 VDC phantom power for microphones.
The integrated player allows scheduled repetition of messages from USB: it automatically plays the MESSAGE_1.mp3 file every 30 or 60 minutes while the music continues, a very useful function for campaigns and periodic announcements in retail and hospitality.
