[Preparation]
1. PC (Personal Computer) which can play back wav files and output digital audio signal at 44.1 kHz (sampling frequency).
2. Software: Given wav-formatted FW Store it in the PC in advance (PC Update) or burn a CD-R with it as a music disc (CD Update).
3. Connection: DIGITAL (OPTICAL/COAXIAL) OUTPUT of PC/CD Player --> DIGITAL (OPTICAL/COAXIAL) INPUT of HTX-22HDX.
* PC needs to be able to handle wav files and output digital audio signal at Sampling Frequency 44.1 kHz.
* For wav-compatible PCs which do not output audio signal at the above specification,
use a commercially-available USB-AUDIO interface unit. e.g. Onkyo-made ND-S1
* Set Sampling frequency to 44.1 kHz and also set Volume to Maximum.
For further information, please see Owner’s manual of your PC.
* Instead of PC, CD players with DIGITAL output terminal can be used.
Note: CD players need to output digital audio signal at 44.1 kHz of Sampling frequency.
Some CD players and DVD players are not suitable for update because they process audio signal to output.
Burn a CD-R as music disc.

<NOTE>
1.
“Writing” will not be shown even more than about 19 seconds passed
after starting playback, audio signal does not output at Sampling
frequency: 44.1kHz.
Check the connection and settings and try again.
When another try results in failure again, use the other update method.
2.
DURING FW UPGRADE,
DO NOT TURN OFF THE UNIT. DO NOT REMOVE ANY CONNECTIONS.
These operation will not allow FW Upgrade any more, and
the whole board or IC will need replacing.
[Procedure]
1. Set MASTER VOLUME value to 10.
2. Hold down [INPUT] button and then press [ON/STANDBY] button.
Main FW version will be displayed.
3. Press [LISTENING MODE] button.
DSP FW version will be displayed.
4. Press [LISTENING MODE] button.
Check Sum will be displayed.
5. Press [INPUT] button.
* Pressing [LISTENING MODE] button changes AUTO ---> COAX1 ---> OPT1 ---> AUTO
6. Press [INPUT] button. (No change)
7. Press [LISTENING MODE] button.
* TOTAL ---> DSP ---> MAIN ---> DSP ----> MAIN
8. Press [INPUT] button.
9. PC upgrade: Play back the wav file stored in your PC.
CD upgrade: Play back the FW CD-R with the connected CD player.
After playback ends (about 19 seconds.), writing will start. It takes about 25 seconds.
<NOTE>Make sure that ”PCM” is shown before starting playback.
About 19 seconds later, the message will change from S/PDIF Update.. to Writing...

QUE DES FUSIBLES DE MEME TYPE. CE DARNIER EST
CE SYMBOLE INDIQUE QUE LE FUSIBLE UTLISE EST
FOR CONTINUED PROTECTION AGAINST FIRE
RATING REFER TO THE MARKING ADJACENT TO THE SYMBOL.
HAZARD,REPLACE WITH SAME TYPE FUSE. FOR FUSE
THIS SYMBOL LOCATED NEAR THE FUSE INDICATES
THAT THE FUSE USED IS SLOW OPERATING TYPE
THE COMPONENTS IDENTIFIED BY MARK ARE CRITICAL FOR SAFETY
REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE.(NO INPUT SIGNAL).
ALL PNP TRANSISTORS ARE EQUIVALENT TO 2SA1015-GR UNLESS OTHERWISE NOTED.
ALL NPN TRANSISTORS ARE EQUIVALENT TO 2SC1815-GR UNLESS OTHERWISE NOTED.
ALL DIODES ARE EQUIVALENT TO 1SS133 UNLESS OTHERWISE NOTED.
ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV.
