TC Electronic Gold Channel, User Manual

SETUP - Signal

15

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.
