JBL Cinema LA4-D DSi 2.0 Series LA4-D 1200W 4-Channel Amplifier

Professional Amplifier Designed For Cinema Applications
The Crown Audio DSi-Series LA4-D is a 4-channel professional cinema power amplifier engineered to deliver precise, powerful, and reliable sound for JBL cinema loudspeakers. With 1200 watts per channel, the LA4-D provides the headroom needed to handle dynamic movie soundtracks, dialogue clarity, and immersive surround effects. Housed in a standard 2RU rackmount chassis, this amplifier offers the perfect balance of performance, efficiency, and control for cinema managers and integrators.

Advanced DSP Processing For Superior System Control
This amplifier features integrated 96 kHz/32-bit floating-point DSP, eliminating the need for an external processor. Built-in functions include 8-band parametric EQ, FIR filters, crossover management, delay adjustment, and LevelMAX limiting. These tools provide unmatched flexibility for system tuning while protecting loudspeakers from overload. The result is an amplifier that not only powers but optimizes every element of the sound system.

High Output Capability For Immersive Audio Systems
The LA4-D is engineered to deliver maximum output power with efficiency, supporting operation down to 2 ohms. This capability allows a single channel to drive up to four surround speakers, making it ideal for Dolby Atmos and DTS:X installations. Its bridgeable outputs further expand system configuration options, ensuring compatibility with a wide range of cinema setups.

Optimized For JBL Cinema Loudspeakers
One of the key benefits of the LA4-D is its factory-loaded JBL cinema speaker presets. These presets ensure the amplifier is perfectly matched to JBL loudspeakers, making system configuration quicker and more accurate. By managing voltage and frequency distribution automatically, the presets provide both protection and improved audio performance, ensuring a reliable cinema sound solution.

User-Friendly Control And Setup Options
The amplifier is designed with practical operation in mind, featuring a front-panel LCD and encoder for easy setup and adjustments. Rear-panel connectivity includes analog inputs via Euroblock connectors, terminal strip speaker outputs, and network ports for software control. Additionally, the GPIO/AUX port allows external control for recalling presets, muting channels, monitoring amplifier health, and powering the unit on or off.

Reliable Technology With DriveCore Efficiency
Crown’s patented DriveCore technology condenses hundreds of components into a single chip, enhancing both reliability and efficiency. The result is superior audio fidelity with reduced power consumption and heat output. Operating quietly with a maximum fan noise of only 51 dBA, the LA4-D is built for stable, long-term performance in demanding theater environments.

Networking And Remote Monitoring Capabilities
The LA4-D includes Dante/AES67 compatibility for seamless audio networking with Dolby Atmos Connect and other compatible devices. SNMP connectivity ensures integration with third-party theater management systems, providing remote monitoring of amplifier and speaker health. Combined with HARMAN’s Audio Architect software via HiQnet, the LA4-D offers complete control, monitoring, and configuration over TCP/IP networks.
