What does HPF stand for?

Next separate your lead sound from your bass - this involves a hefty low cut or high pass filter.

3536 G, decomposition high pass filter coefficients; H, decomposition low pass filter coefficients; K, reconstruction high pass filter coefficients; L, reconstruction low pass filter coefficients.

[ILLUSTRATION OMITTED] The US-Series comprises four models ranging from 700 to 3,200 watts (bridged mono at 4 ohms) and featuring seven-way power protection, built in limiters, high pass filters, balanced 1/4 "and XLR combo inputs, five-way binding post and Speakon outputs, and oversized, high-current toroidial transformers that deliver super-clean, fist-pumping output even when driving a 2 ohm speaker load.

Featuring a dual high pass filter and dual pad, the e70 condenser has an extended frequency response of 20Hz to 20kHz, a low noise design, exceptional sensitivity of-38dBV (13mV) @1Pa, and the ability to withstand up to 150dB SPL, and rugged construction.

The device also has a high pass filter to remove residual DC offsets.

In addition, EQ In/Out switches and steep 18dB/octave High Pass Filters allow effective audio control in difficult venues, while the six auxiliary sends are pre/post switchable m pairs from each channel.

The CS53L21 supports independent control of the left and right channel audio, including digital volume control and mixing, automatic level control and the ability to disable the high pass filters for DC measurements.

Wolfson's proprietary low-order modulator minimizes jitter effects, and a selectable high pass filter is available to remove residual DC offsets.
