Frequently Asked Questions
It employs a ferrite bead filter on the input to attenuate high-frequency interference, which is typical for this class of amplifier and should be adequate for most common scenarios.
Yes, the gradual power-up and power-down prevents sudden gain spikes, which is a valuable feature for minimizing feedback potential when setting up.
While not explicitly stated, expect a THD+N in the range of 0.1%-0.5% at full power, which is typical for Class D amplifiers and acceptable for most live sound applications.
