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!

modules installed in a PC

is Stereo Input, the top
two jacks are Speaker Outputs
(R & L)
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.

What's Next:
Cinemar is producing a
rack mounted case that can
be filled with AMP152 (and
other) modular Cinemar hardware
products for your ever expanding
media and automation control
needs. A higher power version
of the AMP152 is also in
development to drive low
efficiency speakers, or
to support higher dB levels.
