What is “bass roll off?
Bass Roll Off simply decreases the volume of the bass by using two capacitors within the circuitry. Decreasing the bass can result in a better balance of highs and lows during playback if field recording is made in loud, big, boomy bass environments. Bass roll off does not eliminate or cut off the low frequencies. Different input impediances of different models of recorders will give different roll off. Here is a mathematical formula for figuring out what kind of roll you will get with different capacitors. 1/(6.28318 x Farad of the capacitor x Ohm of the recorder’s input) = starting point of roll off. The capacitors we use are .068 micorfarad. Unlike some of our competitors we use the larger, higher quality Polypropylene Capacitors in our battery boxes that are designed for audio low frequency bypass. As a result Giant Squid battery boxes delivers smoother roll off and low distortion.
