Amplifier JBL DSi 2.0 Series

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
