Announcing: Cinemar AMP152 Modular Amplifier

Cinemar's new AMP152 is an economical, easy means to add quality whole house audio to your MainLobby home. The novel amplifier design occupies an unused PC expansion slot and is powered by the PC power supply. The PC sound card audio output simply plugs into the input of the amplifier board. Speaker leads just plug in and you have a zone of audio!

Amplifier Design:

The AMP152 is a new T-Class design which is a high efficiency, high audio quality design. High efficiency allows for a small heat sink free design that won't add much heat to the interiour of the PC case. Power consumption is also minimized allowing reuse of the PC power supply for clean, regulated power. The design also has a very small footprint, which allows for room inside the PC.

But the real benefit of T-Class is the audio quality. This design has been favorably compared to amplifiers costing many times the price. Class T amplifiers offer both the audio fidelity of Class AB (likely found in home stereo receivers) and the power efficiency of Class D amplifiers (usually used in subwoofer amps).With inexpensive PC sound card audio quality exceeding almost all high end audio processors, you can have a quality audio experience at the low price of the AMP152. The AMP152 is perfect to drive high efficiency in wall speakers.

The modular design of the AMP152 makes it super easy to add another zone of audio. Just add another AMP152 card and plug it in! The AMP152 is a perfect mate for MusicLobby 3 multizone audio system. MusicLobby 3 controls the zone's volume of the PC's sound card, which feeds into the AMP152. Installed in the PC, it leverages low cost case and power supply that you already purchased making for a clean, economical alternative to traditional standalone whole house audio controllers.
