FIRMWARE UPDATE-1
DSP Update procedure
[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.

THIS SYMBOL LOCATED NEAR THE FUSE INDICATES
THAT THE FUSE USED IS SLOW OPERATING TYPE
FOR CONTINUED PROTECTION AGAINST FIRE
HAZARD,REPLACE WITH SAME TYPE FUSE. FOR FUSE
RATING REFER TO THE MARKING ADJACENT TO THE SYMBOL.

QUE DES FUSIBLES DE MEME TYPE. CE DARNIER EST
INDIQUE LA QU LE PRESENT SYMBOL EST APPOSE.
NOTE
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).
