PCA2010 PC Internal (PC-Bracket) Power Amplifier

Price: €

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.;


Maximum harmonic distortion is valid if maximum output power is not exceeded.
