I/O Delay
Any A/D or D/A conversion implements a small amount of Delay
time. When D22 analog Inputs or Outputs are used,
compensation for the conversion delay is calculated, and the
displayed Delay time is the total and correct Delay time*.
However this requires correct setting of the Output mode according to the Output you actually are using.
The Outmode is setup in the I/O page 1.
* Note! This is only correct when the set Delay time is 2 ms
or above.
To recall/activate a preset:
- Use the CONTROL ADJUST wheel to scroll through the
presets. Until you confirm your choice you are previewing the
presets. At this stage the OK LED will be blinking.
- When you find the desired preset press OK to recall/confirm.
A preset contains settings of all parameters except Bypass,
RS 485 address and RAM protect, enabling the user to make a
total recall
of a specific setup.
The preset includes:
- All I/O settings
- Current Delay time
- All Utility settings except RS485 address and RAM protect.
- Remote on/off.
All current settings are saved at power off, meaning that D22
"wakes up" in the exact same state as when powered off.
Presets - In General
The D22 holds 4 factory presets.
The presets hold no Delay time but are meant as four basic
relevant setups including I/O settings and Status bits.

When AES/EBU is selected the D22 will send out its own
professional set of status bits, meaning that any incoming ID will
be lost. However, in order to take full advantage of the D22’s
24 bit resolution you should select AES/EBU to make sure that
the receiving device after the D22 will accept all 24 bits.
S/PDIF
When S/PDIF is selected, the D22 will send its own consumer
status bits out, meaning that any incoming ID will be lost. The
D22’s S/PDIF Output carries up to 24 bits.
Thru
When this setting is selected the D22 will send out the same
information as it received.
I/O Delay
Any A/D or D/A conversion implements a small amount of Delay
time. When D22 analog Inputs or Outputs are used,
compensation for the conversion delay is calculated, and the
displayed Delay time is therefore the total and correct Delay
time*. To obtain this please set Output mode according to the
Output are you actually using.
* Note! This is only correct when the set Delay time is 2ms
or above.

APPENDIX - Glossary
Dithering
When going from one type of bit resolution to a lower, e.g. from
24 bit to 16 bit, you actually loose 8 bits of information.
The process of cutting of bits is called truncation and it introduces
digital distortion of low level signals, due to the lack of complete
signal information. To compensate for this, dithering must be
applied. Dithering is a small amount of filtered noise, shaped and
optimized for the human ear, and when added to the truncated
signal the effect is a less distorted low level signal.
Dithering is only relevant on digital Outputs and it is always the
receiving device that determines the number of bits you must
dither to.
A DAT or CDR recorder should always be dithered to 16 bit.
TC Products do not perform truncation on digital Outputs.
Truncation is left to be done by the receiving device.
House Clock
A separate piece of equipment used only to generate a common
standard clock keeping all the attached digital equipment in sync.
Master Clock
If you don’t use a separate House Clock you can use most digital
units for the same purpose. In this case the unit you sync to is
called the Master Clock.
Sample Rate
The quality of sound depends on how precise you can measure
the analog signal. This is done by taking “pictures” of the wave
at a given rate: The Sample Rate.
The maximum frequency that can be successfully reproduced is
the Sample Rate divided by two since you need two points to
define a sinus curve. E.g. the max frequency that can be
successfully reproduce with a Sample Rate of 48kHz is 24kHz.
Sys-Ex - System Exclusive MIDI Commands
Device dependent MIDI commands normally used for remote
control.
AES/EBU
Professional digital In/Out standard, using balanced XLR cables.
The AES/EBU format outputs 24 bit.
S/PDIF
Consumer digital In/Out standard, using coaxial phono-type
cables. This format can generally output 20 bit.
TC products outputs all 24 bits on S/PDIF.
Tos-link
Also called optical S/PDIF. 24 bits can be transferred with this
format.
ADAT/TDIFF
Format capable of transferring 8 channels of 24 bit 48kHz using
optical cables.
Bits & Bytes
1 bit is the smallest unit for information in the digital world. Its
value can be can be 0 or 1 or you could say on/off. 1 byte=8 bit.
Compressor Overshoot
When slow attack times are used overshoots might occur. This
causes an unwanted click/distortion. To prevent compressor
overshoots you can use a brickwall type limiter.
Cross-over point
Splitpoint indicating where the different bands begins/stops
working
dBFS
dB full scale. 0dBFS is the absolute max in the digital world.
Any signal above 0dBFS will cause serious unwanted distortion.

FREQUENTLY ASKED QUESTIONS
Question: What parameters can be set using serial remote
control of the D22?
Answer
: Preset change, Delay time and Bypass using an
RS485/422/232 controller.
Question:
What serial protocol is used?
Answer
: The serial protocol is 9600, N, 8, 1.
This means 9.6 kbaud, no parity, 8 bit, 1 stop.
Question:
What is the command structure for the remote
protocol?
Answer
: #AA,CMD,VALUE<CR>
AA is Unit Address number as set on the Utility page.
CMD is command:
PRE for preset change,
BYP for Bypass,
DEL for delay.
VALUE is (RAM) Preset number, 0 for Not Bypass, 1 for
Bypass or amount of Delay.
<CR> is carriage return, the same as Enter or hex 0D.
Examples:
#05,PRE,10<CR> =Recall RAM preset no. 10 on D22 address 5.
#03,BYP,1<CR> =Bypass D22 address 3.
All commands and numbers are shown as ASCII.
Question: What is the data length of the delay time?
Answer
: The delay is always a decimal number related to the
given delay unit of the D22. It is not posible to change delay unit
via the RS-485, so you must set this manually before you send
the command lines.
Example 1:
The delay unit is ms and you would like to set the delay to 10.5 ms:
#05,DEL,10.5<CR>
Example 2:
The delay unit is frames and you would like to set the delay to
10.5 frames: #05,DEL,10.5<CR>
As you can see there is no difference between example 1 and 2.
Example 3:
The delay unit is ms and you would like to set the
delay to 10.5 frames:
You have to calculate the delay in ms yourself based on the fps
setting and then send a command-line.
Question:
What ASCII characters should be sent for Recall of
RAM preset no. 10 on D22 address 5?
Answer
: #05,PRE,10<CR> means these values (hex) actually
transmitted 23 30 35 2C 50 52 45 2C 31 30 0D

MASTER FADER
Why make a Master Fader?
The Master Fader makes it possible to perform a manual fade on the very Output of the D22 enabling you to keep your fade in the
Digital domain to ensure perfect tracking of left and right.
Connecting and Calibrating the Master Fader
In order to work the Master Fader accurately, the D22 must be calibrated:
- Connect the Master Fader to the “GPI” Input.
- Press and hold the BYPASS key of the D22 while powering up.
- Scroll down to “Fader Calibration” using the MENU keys, and press the OK key.
- Move the Master Fader to maximum position. To compensate for mechanical tolerances draw back the Master Fader slightly.
- Press OK.
- Move the Master Fader to minimum position. To compensate for mechanical tolerances raise the Master Fader slightly.
- Press OK.
- The Master Fader is now Calibrated. Power On/Off.
Activating the Master Fader
To activate the Master Fader, enter the Utility menu and scroll down to “GPI External Input” using the MENU keys.
Dial the ADJUST wheel to choose “FADER”.
The Master Fader is now controlling the Digital fader of the D22. The Fader located in the D22 output section will now
follow and display the movement of the Master Fader.
Cables and Lengths
The Master Fader uses standard mono jack cables. The cable can be extended using the jack to jack adapter, and can run at cable
lengths up to 100 meters. Remember to recalibrate after extending the cable.
