Hi guys,

Does anyone have IR commands (HEX codes) for the Apart Concept a amplifiers, please?

The manufacturer sent us a few HEX values, but not complete commands.

If anyone could help me make sense of how to use these, then I'd be really grateful. Apparently they use the NEC standard and sent the following info:

On/Standby: 5b
Volume Up: 4d
Volume Down: 49
Source A: 52
Source B: 55
Source C: 51
Source D: 54
Mic Vol Up: 5d
Mic Vol Down: 59

Command structure : Concept 1 ID code – command – inverse command.

Example : on/standby : 48 b7 (= Concept 1 ID code) 5b ( = command) A4 (= inverse command)

Do you have the original remote? if you have the original remote and an IR capture kit this is an easy thing to do.
Otherwise sorry, I've never heard of the amp in question.

If they are using the NEC protocol as you stated then this is not hard to do.

There is a program on my web site (the-gordons.net) that will do this producing several output formats, one of them being Pronto HEX, another being iTach timing

You need to build the necessary inout table but all the info is stated in your post.

There is also a document that I wrote many years ago in the files section of remote central that explains Pronto Hex format and the NEC protocol.

I am not sure what output format you requiresince HEX is not an output format but rather a notation for stating what the code parameters are.

Hello

Here you are
