THE BLOCKS

The Blocks

On the following pages you will find a description of the ten processing algorithms, and the parameters you can control in them.

Expander

There are two different expander/gate sub types in the Gold Channel. They are running from the same sub-algorithm, but with different parameters available, fitted for different applications.

Both the Gate and Expander perform Downward Expansion. Downward Expansion in general, means that below a certain threshold the input signal’s gain is reduced on the output according to a specific ratio. For instance, if a Gate or Expander has a ratio 1:2, for every dB the input decreases the output will be decreased with 2 dB. Expanders/Gates are often used to remove background noise from, for instance, old keyboards, or for separating the inputs of different drum mics.

Expander/Gate

Easy Gate

Mode

The Mode parameter changes between fast and slow gating, and covers a change in both the Ratio, Attack, Release, hold and knee mode parameters.

Threshold

When the input signal falls below this threshold, the Gate starts working. This means that the higher threshold the more gating you will get.

Max. Damping

With this parameter you can decide the maximum number of dB the gate shall attenuate (See the graphics to get a better understanding).

SIDECHAIN

The Sidechain is the reference signal that the Gate is listening to internally for making the processing. You will never hear this signal on the output.

Input

When placed on Channel 1, you can select the Sidechain Input to be either the Same (Ch.1) or Channel 2.

Example: If you select to have Sidechain input from Ch.2, you can go to the Layout page and select Ch. 1 Pre, as input to Ch.2. Now you have all the blocks on Ch. 2 for processing the Sidechain signal on Ch. 1. You can also have a completely different input on Ch. 2.

NOTE: When two blocks are linked, you cannot select Ch. 2 as input for Ch. 1 Sidechain.

Advanced Expander

Threshold

When the input signal falls below this threshold, the Expander/Gate starts working. This means that the higher threshold the more expansion you will get.

Ratio

The Ratio of the gain reduction. If the Ratio is set to 4:1 it means that for every 1 dB the input signal decreases, the output will decrease by 4 dB.

When the Ratio is set Infinite:1, it means that when the input signal falls below the threshold, the output is turned all the way down. This is also known as gating.

Attack

The Attack is the time that the Expander/Gate uses for bringing the reduced signal to 1:1, when the signal exceeds the threshold.

Gold Channel specifications

TC Electronic SDN BHD has established itself as a pioneer in audio technology, and one of its standout products is the SDN BHD Gold Channel. This innovative device is designed for professional audio applications, particularly in live sound and broadcast environments. The Gold Channel is revered for its exceptional sound quality, versatility, and user-friendly interface, making it a go-to choice for audio engineers and musicians alike.

At the heart of the Gold Channel is its advanced signal processing technology. It features a high-quality preamp that provides a clean and transparent sound, essential for capturing the nuances of live performances. The preamp is complemented by a robust equalization section, allowing users to shape their sound with precision. The three-band EQ offers both high and low shelving controls, as well as a parametric mid-band, facilitating a wide range of sonic possibilities.

Another significant feature of the Gold Channel is its dynamic processing capabilities. It incorporates a powerful compressor that helps manage dynamic range effectively. Users can achieve everything from subtle compression to more aggressive limiting, ensuring that audio levels are consistent and professional. The onboard de-esser helps eliminate sibilance, making vocals smoother and more polished.

In addition to these core features, the Gold Channel also includes an excellent built-in digital effects processor. This allows users to add reverb, delay, and modulation effects directly within the channel strip, streamlining the mixing process. The intuitive controls make it easy to dial in effects quickly, which is particularly beneficial in fast-paced live settings.

Connectivity options are another strong suit of the Gold Channel. It features multiple input channels, including XLR and TRS, accommodating a variety of microphones and instruments. The outputs are equally versatile, providing balanced and unbalanced options for seamless integration with other audio equipment.

Furthermore, the Gold Channel boasts robust build quality, designed to withstand the rigors of live performances. With a sleek metal chassis and reliable components, this device is built for longevity.

In summary, the TC Electronic SDN BHD Gold Channel combines high fidelity sound, advanced processing features, and practical connectivity options into a single, powerful package. Its remarkable flexibility makes it an essential tool for audio professionals dedicated to delivering outstanding sound quality in any setting. Whether in the studio or on stage, the Gold Channel stands out as a premier audio solution.
