Fosi Audio - ZA3-48V5A Stereo Amplifier

Note: A 32 Volt ZA3-32V5A is also available from Fosi. 48 V is better than 32 V because it can handle more current, which speakers love.

Features

• XLR (Balanced) & RCA Input Choice
• Op-Amp Rolling: SS3602, MUSES02, OPA2134PA
• In stereo mode, each speaker sees up to 155W
• In mono mode, the power reaches 235W with lower crosstalk

Upgrade without Replacement

• Purchase a second ZA3 later and run them in dual-mono mode - one for each speaker
  
• Upgrade your sound without purchasing a new amplifier by replacing its standard op-amps
• Increase bass by adding a self-powered subwoofer

ZA3 vs V3 Mono

• Both use upgraded components from countries around the globe
• Both can use XLR or TRS inputs for input noise before power amplification
• A 12 V trigger signal can turn on/off the ZA3, but not the V3 Mono
• If you're buying a dual-mono initially, the V3 Mono uses advanced PFFB post-filter feedback, an advanced Class-D design.
