100W Power Amplifier AA-2500

• alternative name: Heath Company

SKILL LEVEL 2

Featuring a High instantaneous Current Capability (HCC) of 60 amps, the 2500 Power Amplifier develops far more power under peak loads than its already impressive 100W per channel. The result is more headroom to handle today’s demanding digital recordings.
Specially designed for Heath by Harman Kardon, the 2500 also demonstrates exceptionally wide bandwidth due to its low 12dB of negative feedback which provides improved transient accuracy and phase linearity. In addition, a massive toroidal power transformer eliminates the stray magnetic fields that cause hum. And, the power supply and amplifier circuitry include high grade capacitors with extremely low loss.
A superior example of high technology electronics, the 2500 features four dual polarity power supplies that eliminate channel-to-channel interference and assure proper balance of current between high and low level stages.
Another advanced feature of the 2500 is a protection circuit that shields speakers from turn-on transients and prevents short circuit by muting audio if a load of less than 2 ohms is placed across the speaker terminals.
When you assemble the AA-2500 yourself, you save money and get the satisfaction of knowing the care and effort you put into the construction of your new amplifier. Dimensions are 5¾"H x 17½"W x 14½"D.
