Anthem MCA-30

This has been a very nice amp which I used to power center and surround speakers.
I see no visible scratches in the photos, but I did notice a small scratch on the right side - hence the '8' rating. Has been in a smoke-free home its entire life. Selling because I need more channels for Atmos upgrade.

Includes original box.

ADVANCED LOAD MONITORING (ALM)
All Anthem ® amplifiers are designed to perform flawlessly—offering stunning musicality, tonal neutrality and incredible dynamics while driving any speaker load reliably under real-world conditions!

The power supply is conservatively rated and the amplifiers run cool for greater reliability, but we didn’t stop there.
These amplifiers feature our ALM (Advanced Load Monitoring) circuitry which protects sensitive output devices by constantly monitoring temperature, current and voltage to ensure optimum long-term performance. ALM is totally non-invasive—it is not in the signal path and only engages in the most extreme circumstances to protect the amplifier from damage by maintaining the safe operating area of the output devices. Buyer beware however! Not all amplifier manufacturers have sophisticated load-monitoring provisions. Many have saved the added cost, leaving their output devices unprotected, choosing instead to use the amplifier’s output devices as “fuses.” At Anthem, ALM is just one of the ways in which our products provide owners with years of reliable service.
