HiFi power amplifier module,
mono, 48W_MAX/4Ω, complete version with mains rectifier and electrolytic capacitors. HiFi stereo amplifiers, compact amplifiers, and active speaker systems can easily be built. Only a mains power transformer is additionally required for the operation.

Further features:

Muting circuit, short circuit-proof, low THD, very low intermodulation distortions, wide power bandwidth, high input sensitivity, internal overload protection (SOAR).

Recommended fan CF-60/BB available at option (necessary for 4Ω operation).
