SPA500 subwoofer amplifier, one of the most versatile and powerful sub-
woofer amplifiers available. The SPA500 has the power to drive even the most power-hungry subwoofer systems.
FEATURES:
• Patented tracking downconverter power supply for
high efficiency
• Class AB output stage for clean, controlled output
• Low frequency parametric EQ allows you to boost or
cut to custom-tailor the sound
INSTALLATION:
The SPA500 is designed to provide high fidelity subwoofer amplification and is tailored for home audio, home theater, and
studio environments.
It is not recommended for use in DJ, pro-sound, or other high-duty-cycle applications. The amplifier runs cool thanks to its
high efficiency, but care should be taken to leave some room for air circulation above and behind the amplifier.
