JBL DSi 2.0 MA4 4-Channel Amplifier for JBL Cinema Speakers, 750W @ 8 Ohms

JBL DSi 2.0 MA4 4-Channel Amplifier for JBL Cinema Speakers Features

- Each amp offers 4 channels with bridgeable outputs to easily power JBL"s entire line of cinema speakers.
- Amplifiers are engineered to meet exact power requirements of JBL cinema speakers, for a single JBL cinema solution.
- A new amplifier design allows for high power output at 2Ω (SA and MA models), enabling up to 4 surround speakers to be powered by a single channel.
- D-models interface with Dolby Atmos directly, without the need for additional processing hardware.
- All models feature SNMP and ethernet connectivity for networking and third-party control; SA4-D, MA4-D and LA4-D models add Dante/AES67 connectivity.
- All models include a HiQ port to interface with HARMAN Audio Architect control software over a standard TCP/IQ network.
- Best-in-class, 96kHz/32-bit floating-point processing incorporates FIR filtering, LevelMAX limiting, 8-channel parametric EQ, delay settings and more.
- Crown DriveCore technology replaces hundreds of amplifier parts with a single chip, for superior efficiency and reliability.
- Built-in JBL Cinema Speaker presets match all JBL cinema loudspeakers; amps are power-matched with JBL cinema speakers for optimal performance and fast system configuration.
- Recall presets, mute channels, monitor amplifier health and power on and off through a combined GPIO/AUX port.
- SNMP connectivity allows direct interfacing with third-party theater-management and cinema-control systems.
- An intuitive front-panel LCD and encoder interface let you configure amplifier settings at the push of a button.
- Ultra-quiet operation: 51dBA maximum fan noise
- All models are standard 19-inch (482mm) 2RU rackmount units.
