About the PSB CS 500W
Rock out your custom-installed subwoofer
Rock out your custom-installed subwoofer
If you're running passive subwoofers in your home theater or audio system, the PSB CS 500W is a great choice. This 500-watt power amplifier is designed to drive up PSB's 4-ohm CSIW SUB28 perfectly. It can also be used to power a pair of massive 8-ohm subwoofers.
The CS 500W's built-in digital signal processor (DSP) allows you to optimize your EQ settings, so you can make sure the low end hits exactly the way you want it. If you're using a passive sub from PSB, getting the right sound is even easier, thanks to EQ profiles for specific PSB subs.
Convenient setup
The subwoofer amplifier comes with a handy rack mounting kit, with removable ears and feet. The amp's compact size lets it snugly fit into a 1U rack space, making it easy to organize alongside your other equipment. You can start the amp up from standby with automatic signal sensing or link it to other components in your system with a 12-volt trigger. Using the RCA outputs, you can even daisy-chain additional amplifiers — letting you power them all on simultaneously.
Built-in failsafe
A limiter circuit acts as a filter to prevent the amp from pushing a subwoofer outside of its appropriate operating range. This helps keep your equipment safe in the event you get a little too excited with the volume control, and try to drive your subs too hard.
