2.2 Low and High- Shelving

The term “Shelving” (shelve = to slope gradually)

describes the filter slope of this equalizer. For

example: with a high-shelving equalizer all the

frequencies above the selected frequency are

boosted evenly. For frequencies below that point,

the boosting gradually declines to zero.

Operation:

FREQUENCY: sets the cut-off frequency of this

EQ band.

LF: Operating range from 22 Hz to 700 Hz.

HF: Operating range from 840 Hz to 30 kHz.

HF & LF: switches the respective EQ band into

the signal path.

LEVEL: permits a boost of +15 dB and a cut

of -25 dB.

Q: adjusts the bandwidth of this frequency band.

Filter Bandwidth: See Section 2.3.

PureParallel™-Technology

Normally, filters are placed in the circuit one after

another (serial). As a result, the complete frequency

spectrum of the signals goes through all the filter

stages, which can lead to a considerable degradation

of the signal’s quality. You can think of this like a

winding, one-lane road that slows down the signal.

In contrast, the equalizer of the DTC™ uses parallel

filters, so that the signal is divided into four bands at

the same time. Like a straight four-lane Autobahn,

on which the signal moves ahead without

any obstructions.

Serial circuitry versus parallel circuitry.

The colors represent frequency bands.

QUESTION: How is the original signal

handled passively?

ANSWER: The original signal goes through the EQ

practically like through a thick cable, without

interruption. The bands of EQ, which are laid out

parallel to the original signal, only operate on those

frequencies that are to be processed. If a frequency

range is to get a boost, it will be mixed into the

original signal in phase, and if cut, with phase

reversed. But the original signal remains. This way,

you manage to keep fidelity to the original signal at

an optimum.
