interfaces
The DSi 2.0 amplifier family, JBL’s first line of dedicated cinema amplifiers, builds on Crown DSi Digital Screen Array amplifier technology and best-in- class DSP from Crown’s flagship CDi DriveCore Series to deliver potent, efficient amplification and top-notch processing for JBL’s entire range of cinema loudspeakers. Cinema managers and integrators looking to maximize their power investment and future-proof their systems can count on JBL DSi 2.0 Series to deliver robust, reliable performance in an ultra-efficient package.
KEY MESSAGES
BEST-IN-CLASS DSP
DSi 2.0 amplifiers feature best-in-class, 96kHz/32-bit floating point internal
processing with delay (up to 1,000 ms), 8-band parametric EQ, crossover, FIR
processing, Level MAX™ limiting and more, eliminating the need for an external
processor.
SUPERIOR POWER DENSITY MEANS BETTER VALUE
Crown’s patented DriveCore technology seamlessly integrates the amplifier
drive stage into the power output stage, fusing everything into one powerful
chip to deliver greater efficiency, reliability and performance. Using
DriveCore, DSi 2.0 amps deliver greater power density than traditional
designs, offering 4 channels of amplification with bridgeable outputs in a
single 2U footprint. Using high-output 2Ω mode allows powering of up to 4
surround speakers from a single channel.
DEDICATED JBL SPEAKER TUNINGS
Built-in JBL cinema speaker tuning presets manage voltage and frequencies
delivered to transducers, maximizing system efficiency and optimizing audio
signal quality while preventing equipment damage and accelerating deployment.
REMOTE MONITORING AND MANAGEMENT
SNMP connectivity for interfacing with third-party theater management systems
and Cinema Control (NOC) systems for remote status and fault monitoring. A
HiQnet port provides access to HARMAN’s Audio Architect software, for
controlling, configuring and monitoring amplifier operation through a standard
TCP/IP network. A combined GPIO/AUX port can be used to externally recall
presets, mute channels, monitor amplifier health and power the amplifier on
and off.
AUDIO NETWORKING (SA4-D, MA4-D AND LA4-D MODELS)
AES67 connectivity allows networked audio distribution from any
Dante/AES67-compatible device and direct interfacing with Dolby Atmos Connect
interfaces.* Dual network audio ports support primary and secondary networks
configured as switched (daisy chain) or redundant (star) systems.
*Available via a firmware update.
