VC LINE

“Variable Curvature Line Array.“

VC LINE Amplification.

TA 4D - 4 channel system amplifier

We recommend driving up to 8 elements with a TA 4D system amplifier. Better sonic performance is achieved with fewer elements, allowing more accurate processing. — We recommend driving up to 8 elements with a **TA 4D** system amplifier. Better sonic performance is achieved with fewer elements, allowing more accurate processing.

CA 4D - 4 channel system amplifier

If the maximum power of VC LINE is not required but there is a preference for more accuracy, we recommend replacing the TA 4D with two CA 4D or adding a CA 4D to a TA 4D. — If the maximum power of **VC LINE** is not required but there is a preference for more accuracy, we recommend replacing the **TA 4D** with two **CA 4D** or adding a **CA 4D** to a **TA 4D**.

Precision amplification

Anyone familiar with Line Arrays knows that the frequency characteristics of the array change with different lengths, especially at low frequencies. Changing the Splay affects the frequency response at high frequencies. With the latter phenomenon, the change already takes place at minimal changes in the angle of two elements to each other.

This was the reason for KS AUDIO to carry out very extensive measurements and for each change in the array. Even the minute differences that arise from a small change in the Splay between two elements were measured. The resulting data was converted into accurate presets for our DSP software.

If adjacent elements are at the same angle, they can be driven by one bi-amp channel, and up to 4 elements can be driven this way. So one amplifier is two bi-amp channels are a maximum of 8 VC LINE elements.

However, since line arrays rarely, if ever, hang at a 0° angle, KS AUDIO recommends using one amplifier bi-amp channel for each differently set splay angle to achieve the best result.

Incidentally, the differences in the adjustment of the equalisation become smaller with larger opening angles. Therefore, with larger opening angles - usually at the bottom of the array - the need for separation between channels is less significant.

In practice, this means that a line array with approximately 8 to 10 elements can be driven by two CA 4D or TA 4D, i.e. four bi-amp channels, perfectly well. The TA 4D of the two has more power, which results in an increase of approx. 3dB SPLmax.
