SETUP - Signal

ADAT - When using an ADAT, use the Parameter wheel to move the cursor to the channel 1 or 2 input boxes, and the Value wheel to select channel number. It is possible to select two ADAT channels, process them and send them out on two different - or the same - ADAT channels. The incoming sample rate will be displayed in the Digital box at the Signal page. The “Digital” LED’s will be blinking if no clock is present or if the Gold Channel can not lock to the incoming clock.

NOTE: The four or six unprocessed ADAT channels are not passed through the Gold Channel.

Insert Send and Return

The Insert Send and Return in the Gold Channel is not a normal send/return as on other mixers, but a more comprehensive way of using the inputs and outputs. This means that depending on what you select as your primary input, most other inputs and outputs are free for use as insert sends or returns. The only limitation is that both input channels must be either analog (Mic or Line) or Digital, to enable the send/return feature.

Example: If the Gold Channel is set up with mics on both inputs, it is then possible to use the AES/EBU in/outs to connect another processing machine or effect in the signal chain.

For further details and options see “Connecting the Gold Channel” (page 11-12) and “Edit” (Page 23).

NOTE: The Input select overrides the Insert send/return, meaning that the setting selected at the Input cannot be chosen at the Insert return. Also note that the Insert option will automatically be turned off when both channels are not either analog or digital.

Clock

The Clock parameter determines what source the Gold Channel is using as digital clock. The Gold Channel can use internal 44.1 kHz, internal 48 kHz, incoming Digital sample rate (from the selected Digital input) or external sync (word clock).

The Gold Channel is capable of using its own internal clock while using audio from the Digital input. This means that you can use the Gold Channel as master clock when working in a digital setup. The Gold Channel will automatically switch to the appropriate clock when you select Input source. For instance, you select AES/EBU as your input source, the Gold Channel now automatically switches the Clock parameter to Digital.

NOTE: The external sync input will only recognize standard word clock from 32 kHz to 48 kHz.

Digital External Clock

When the Gold Channel is locked to any external clock, this box will display the incoming sample rate.

Dither

The Gold Channel can output Dither from 8 to 22 bit resolution. The dither type is HP-TDF or High Pass Triangular probability Density Function.

Gold Channel uses internal 24 bit resolution and 24 bit AD/DA converters. Dither should therefore only be used in case the digital outputs are used (e.g. to a 16 bit DAT machine). It is recommended not to use dither until the final stage of a production, so if there is a chance that the source material is going to be dithered later in a production, do not use Dither.

Output

The Gold Channel will output signal on all available outputs simultaneously.

Example: If the Gold Channel is set to Mic input on both channels and off at Insert send/return, you will have both analog, AES/EBU, S/PDIF and TOS link (or ADAT) outputs available. The TOS link can be switched to any two ADAT channels between 1 and 8. When using ADAT, use the Parameter wheel to move the cursor to the “Optical” box, and the value wheel to select ADAT and channel number for each channel.

The output box will automatically show you what outputs are available according to your choices of Input and Insert.

Use the Value wheel to change the Channel Status Bits of the digital output between professional and consumer format. When AES/EBU is above S/PDIF in the list, the Gold Channel will output the professional AES/EBU standard, and when S/PDIF is on top of AES/EBU, the Gold Channel will output the S/PDIF consumer standard.

The Gold Channel defaults to AES/EBU but some digital consumer products refuses to accept the professional standard. In that case change to S/PDIF consumer standard.

Example: If you are using a non-professional DAT machine as a receiver of the Gold Channel digital output, and you cannot make it accept the digital input, change the output format from AES/EBU to S/PDIF.

NOTE: The different Status Bit standards do not affect the quality of the audio output from the Gold Channel.

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.
