Works well and sounds excellent! This would make a nice powerful home amplifier if you swapped the fan for a low noise fan. Nice clean powerful PA amplifier that sounds great! Stereo mode (both channels driven): 240 watts into 4 ohms. 200 watts into 8 ohms.Bridge-Mono mode: 455 watts into 8 ohms. 395 watts into 16 ohms.Parallel-Mono mode: 455 watts into 2 ohms. 400 watts into 4 ohms.Features❏ Rugged, professional power amplifier mounts in a standard 19 inch (48.3 cm) equipment rack.❏ Front panel power switch with turn-on delay for loudspeaker protection.❏ Full, uncolored power with any reasonable load.❏ Patented Output Device Emulation Protection (ODEP®) keeps the amplifier working when others would fail. ❏ High damping factor provides superior control over low frequency drivers for a clean, accurate low end.❏ Safe with any load. Bridge-Mono and Parallel-Mono modes offer optimal load-matching performance.❏ Complete protection against shorted outputs, mismatched loads, overheating, DC input/output and high frequency overload; full internal fault protection.❏ Balanced phone jack inputs with internal three-position sensitivity switch. ❏ Ground lift switch helps prevent “ground loops” by isolating the chassis from the phone input grounds.❏ Efficient heat sinks and self-contained forced air cooling system dissipate heat quickly and evenly for extra amplifier protection and greater power output.
Is this a solid buy for a clean, working 460 CSL at a bargain price? Yes: at US$109, it lands well below the US$133 25th percentile and is a genuine deal versus the US$279 median, especially for a tested unit.
That’s what makes it appealing: Crown’s CSL amps are rugged, sensible rack pieces with real output, good damping, and the kind of no-drama reliability people want for home, studio, or small install duty. If the listing is accurate on working status and the chassis isn’t beat up, this is the sort of under-the-radar pro amp that can be a strong value play.

Crown Audio traces its origins to 1947 in Elkhart, Indiana, where minister and radio enthusiast Clarence C. Moore, alongside his wife Ruby, founded the International Radio and Electronics Corporation (IREC) in a converted chicken coop. Initially focused on rugged open-reel tape recorders for missionaries in remote regions, the company pioneered innovations like the world's first tape recorder with a built-in power amplifier in 1949. Ruby's suggestion in the 1960s led to the adoption of the Crown name, inspired by the crown emblems on their 'Royal' and 'Imperial' models, with the corporation officially renaming to Crown International, Inc. in 1975.
The brand shifted from tape recorders and compact loudspeakers in the 1950s to standalone tube power amplifiers by 1959, cementing its expertise in professional amplification. Crown became renowned for groundbreaking products like the DC300 in 1968—the first high-power solid-state amplifier—and the M600/M2000 in 1972, featuring patented technologies such as the ground-bridge circuit. Today, under Harman International since its 2000 acquisition, Crown specializes in high-output amplifiers for touring rigs, cinema venues, installed systems, portable PA, and commercial audio, prioritizing reliability and innovation over consumer categories like speakers, turntables, DACs, headphones, or cables.
Crown holds a commanding position as a pro-audio powerhouse, trusted by industry leaders for its durable, high-performance amplifiers that define live sound and installation standards. Far from high-end audiophile or vintage collector fare, it dominates the professional market with over 75 years of technical milestones, though recent production shifts to Mexico reflect ongoing evolution. For the discerning hi-fi buyer eyeing pro-grade power, Crown delivers uncompromised authority.
