Crown DSi 1000 Power Amplifier

If any company knows how to build a great power amp, it's Crown.
They've been building rock-solid power amps for over 30 years, and their latest, the DSi-Series, has been engineered from the ground up for unmatched quality and performance.


The Crown® DSi Series of power amplifiers offers three models of 500W, 800W, and 1200W per channel at 4 ohms.
Onboard digital signal processing includes crossovers, EQ filters, delay and output limiting. Rear panel HD-15 connector provides easy input/ output connectivity between DSi amplifiers and the new DSi-8M System Monitor.

At the touch of a button, Crown’s DSi cinema amplifiers deliver perfectly matched performance with each award-winning JBL Screen- Array system, making this the ultimate cinema sound system solution.

The intuitive front panel LCD screen guides installers through a setup process—featuring presets for the industry-standard JBL cinema loudspeaker systems—to make configuration quick and easy.

Crown’s DSi-Series cinema amplifiers are backed by Crown’s Three-Year, No-Fault, Fully Transferable Warranty.
