JBL Professional VMA1120 - 5-Input 120W Commercial Mixer/Amplifier (70/100V & 4/8 Ohm, Bluetooth & USB)

The JBL Professional VMA1120 is a 1-channel, 5-input mixer/amplifier designed for commercial audio installations requiring operational simplicity and reliability. It delivers 120W of output and can drive low-impedance (4/8 Ω) speakers or 70/100V lines without external transformers. It incorporates a multimedia player with Bluetooth and USB , priority function with chime and VOX ducking for announcements, 27V phantom power on mic inputs and remote volume control via CSR-V . Its electronics include ±14 dB bass and treble equalization on the output, 20 Hz–20 kHz response (4/8 Ω mode), THD < 0.5% and SNR > 76 dB(A) , inside a 2U chassis with rack hardware included.

Main features

• Power and outputs: 120 W max. (1 kHz, ≤0.5% THD) switchable between 4/8 Ω or 70/100 V ; insertion loss at 70/100 V ≤ 1 dB . Automatic high-pass filter at 70 Hz when using 70/100 V.
• Inputs (5 channels):
  • CH1–CH2: balanced mic/line in Euroblock (with 27 V phantom , switchable MIC/LIN gain and priority on CH2 with PTT contact).
  • CH3: Balanced line on 6.35 mm TRS .
  • CH4: line via Euroblock or RCA (selectable).
  • CH5 (MUSIC): stereo RCA input added to mono.
• Integrated player: Bluetooth and USB for MP3 files, with key/indicator on the front panel.
• Control and processing: Bass and treble output ( ±14 dB @ 50 Hz / 10 kHz); VOX ducking on CH2; chime for announcements; priority mute by contact closure.
• Remote control: RJ45 port for CSR-V (volume control via wall socket with CAT5 cable).
• Speaker connections: barrier block for COM/70/100 V and 4/8 Ω output.
• Construction and installation: 2U (88 mm) chassis with rack-mount kit included; multi-voltage 100/120/220/220–240 V , 50/60 Hz.

Product benefits

• One unit for everything: mixing of 5 sources and amplification in low impedance or 70/100 V lines.
• Simple operation: clear front controls, chime and message priority, and Bluetooth/USB without external sources.
• Professional integration: CSR-V wall control, 27 V phantom power for installation microphones and automatic filter to protect speakers at 70/100 V.
• Consistent sound: Output EQ and headroom with THD < 0.5% , SNR > 76 dB(A) and wide response.

Use cases

• Retail, hospitality, and catering: ambient music with timely announcements and simple areas.
• Education and corporate: classrooms, meeting rooms, reception, and hallways with priority messages.
• Places of worship and leisure: voice reinforcement and music playback with local volume control.

Compatibility and operation

• CSR-V: Remote volume control via RJ45/CAT5.
• Priority and VOX: CH2 can mute the others via PTT; configurable VOX ducking and activatable chime .
• Bluetooth/USB: MP3 playback from USB memory or Bluetooth device (front panel control).
• Minimum load: 4 Ω (low Z output), 40 Ω at 70 V and 80 Ω at 100 V.

Frequently Asked Questions

• Can I use 8 Ω speakers and 100 V lines? Yes, the output mode is selected by an internal switch; in 70/100 V, a HPF is automatically applied at 70 Hz.
• Does it have phantom power for installation microphones? Yes, 27 V selectable per mic channel.
• Can the volume be controlled from the wall? Yes, using the CSR-V module.
• Does it include Bluetooth? Yes, the media player plays MP3s from Bluetooth and USB .
