HiFi power amplifier modules,
in stereo (IPA-222) or mono (IPA-20, IPA-10) with different output power. HiFi stereo amplifiers, compact amplifiers, or active speaker systems can easily be built with the modules. A 12V DC voltage (max. 18V DC current ) is required for operation.

Common features

• Short circuit-proof
• Thermic overload protection
• Reliable power amplifer IC technology with low THD

Additional features

of models IPA-222 and IPA-20

• Bridge circuit (BTL)
• Muting circuit (no On/Off switching noises)
• Internal speaker protection against DC and AC voltages
