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.  
Tap Mode - Instant or Preview  
The tap mode is setup in the Utility menu. (Please see page 17).  
Instant (destructive):  
The preset includes:  
When Instant mode is selected the TAP key LED will be red.  
Tap the desired Delay time and the D22 will instantly update the  
Delay time.  
- All I/O settings  
- Current Delay time  
- All Utility settings except RS485 address and RAM protect.

All current settings are saved at power off, meaning that D22  
"wakes up" in the exact same state as when powered off.  
Preview (non-destructive):  
When Preview mode is selected the TAP key LED will be green.  
The Delay time will be displayed and blink, indicating that the  
displayed Delay time is not yet recalled.  
Press the OK key to activate the tapped previewed Delay time.  
The Tapped Delay time is always rounded to nearest increment  
setup in the Utility menu.  
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.  
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 accord-  
ing to the Output you actually are using.  
Preset #1 : Analog I/O AES  
Preset #2 : Analog I/O NTSC  
Preset #3 : Digital I/O AES/EBU  
Preset #4 : Digital I/O S/PDIF  
Presets 1-4 are write-protected.  
The Outmode is setup in the I/O page 1.  
You can store presets on locations 5-127.  
* Note! This is only correct when the set Delay time is 2 ms  
or above.  
14  
 
RECALL  
Fader  
By connecting a TC Master Fader to the External Control In,  
on the rear panel you are able to remote control the digital  
Output fade. When the fader pot is moved the Recall display will  
instantly show you the fader position in the lower half.  
When the fader has not been moved for approx. 3 seconds the  
fader indication will disappear.  
When Fader is set to 0dB, an Arrow indicator appears to confirm  
maximum level.  
Locked mode  
To avoid accidental changes in parameter values you are able to  
lock all keys on the front panel. A padlock symbol will appear  
instead of the Tap mode.  
This function is activated by pressing and holding the RECALL  
key for approx. 3 seconds.  
To release the unit from the locked mode, press the RECALL key  
again for approx. 3 seconds.  
Seamless preset changes  
To obtain perfectly seamless update when changing presets, I/O  
and Utility settings must be the same in both presets.

The I/O section holds two pages. Press the I/O key  
once to enter I/O page 1, and once more to enter I/O

to the Recall page.  
AES/EBU  
Input:  
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.  
Select Input source: Analog, AES or S/PDIF.  
- Analog defaults to 48kHz internal clock.  
Out status bit defaults to AES.  
- AES defaults to AES clock.  
- S/PDIF defaults to S/PDIF clock.  
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.  
Sample Rate Conversion  
Determines whether the Sample Rate Converter is On or Off.  
The SRC works according to the selected clock.  
Thru  
Clock  
When this setting is selected the D22 will send out the same  
information as it received.  
Selects master clock: Int 44.1, Int 48, Ext. Sync, AES, S/PDIF.  
Dither  
I/O Delay  
Selects Output dither: 8, 12, 16, 18, 20, 22 or 24 bit (Off).  
Dither is only present on Digital outputs.  
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.  
Output  
Selects the Output status of the D22. Select between:  
Analog, AES, S/PDIF or Thru.  
* Note! This is only correct when the set Delay time is 2ms

APPENDIX - Glossary  
AES/EBU  
Dithering  
Professional digital In/Out standard, using balanced XLR cables.  
The AES/EBU format outputs 24 bit.  
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.  
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.  
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.  
ADAT/TDIFF  
Format capable of transferring 8 channels of 24 bit 48kHz using  
optical cables.  
House Clock  
A separate piece of equipment used only to generate a common  
standard clock keeping all the attached digital equipment in sync.  
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.  
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.  
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.  
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.  
Cross-over point  
Splitpoint indicating where the different bands begins/stops  
working  
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.  
dBFS  
dB full scale. 0dBFS is the absolute max in the digital world.  
Any signal above 0dBFS will cause serious unwanted distortion.  
dBu  
Sys-Ex - System Exclusive MIDI Commands  
Device dependent MIDI commands normally used for remote  
control.  
Measuring unit in the analog world.

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 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.  
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.  
Example 1:  
The delay unit is ms and you would like to set the delay to 10.5 ms:  
#05,DEL,10.5<CR>  
Question: What is the command structure for the remote  
protocol?  
Example 2:  
Answer: #AA,CMD,VALUE<CR>  
The delay unit is frames and you would like to set the delay to  
10.5 frames: #05,DEL,10.5<CR>  
AA is Unit Address number as set on the Utility page.  
CMD is command:  
PRE for preset change,  
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:  
BYP for Bypass,  
DEL for delay.  
VALUE is (RAM) Preset number, 0 for Not Bypass, 1 for  
Bypass or amount of Delay.  
You have to calculate the delay in ms yourself based on the fps  
setting and then send a command-line.  
<CR> is carriage return, the same as Enter or hex 0D.  
Question: What ASCII characters should be sent for Recall of  
RAM preset no. 10 on D22 address 5?  
Examples:  
Answer: #05,PRE,10<CR> means these values (hex) actually  
transmitted 23 30 35 2C 50 52 45 2C 31 30 0D  
#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.

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.
