PCA2010 PC Internal (PC-Bracket) Power Amplifier
Back in old times sound
cards had power amplifiers. Although this was allowing use of non-powered
speakers, it had a serious drawback – output power was in the miliwatt range.
Nowadays every PC-intended speaker is powered, but unfortunately most cheap
solutions offer remarkably bad sound quality.
Here comes the PC-bracket
power amplifier allowing those old and forgotten, but hi-quality speakers to be
brought back to life and connected directly to any PC. Nor it is tiny and
cost-effective, it also saves from yet another powered box near the PC.
Amplifier’s output power is more than adequate for any desktop, and for most
small to mid-sized rooms as well. Sound quality is very good thanks to low
harmonic and cross-over distortions (provided that high quality speakers are
used).
The PCA2010 PC-amp is very
robust and flexible allowing connection of practically any (non-powered) speaker
down to 1.6Ω. It also offers a completely safe operation providing automatic
overheat protection, protection against any type of short circuit, open ground
protection, load dump voltage surges protection.
The PC-amp fits in
one of any standard PC case back-plate full-height extension card openings, no
matter what slot is inside – it simply doesn’t use them. Power big enough for
adequate sound levels and dynamics is drawn directly from PCs power supply via
standard Molex connector.
What the user
must know and understand: In order to be more affordable the PCA2010
PC-amp doesn’t have its own cooling system. Heat generated during operation is
dissipated via the back PC bracket and PC case assisted by PC’s cooling system.
Depending on factors like ambient temperature, PC cooling efficiency, and how
loud the sound is, amp temperature may reach inacceptable levels causing the
built-in thermal protection automatic kick-in. This will cut the sound off, but
it will be automatically restored as soon as the temperature lowers to
acceptable level. Such behavior is not
a malfunction. Tests show that with normal sound levels and normal PC
cooling this practically doesn’t happen. For more information and installation
procedure please refer to
User's manual.

Notes: |
1. |
Maximum output power depends on speaker
impedance, ambient temperature and PC cooling efficiency. Maximum
values are valid for a well cooled PC, otherwise may be limited by
automatic thermal protection kick-in. Maximum output power specified
is pure electric power (sine), not 'P.M.P.O.', ‘Music power’, etc.;
|
2. |
Maximum harmonic distortion is valid if
maximum output power is not exceeded.
