Does anyone have an idea on how to set a volume level? Have an ARCAM AVR600 Receiver. The sound has to be set higher when playing a moving coil turntable source. When I switch inputs, for example to tuner, the sound about blows me out of my chair. I had put in a series of volume down commands before send the IR code to switch the source. But, this is time consuming and not very graceful. I don't see an IR code that allows me to set the volume level to a particular strength.

Any ideas on way to programmatically doing this would be appreciated.

"I don't see an IR code that allows me to...." Please tell us all of the places that you're looking.

There may be IR codes for that unit that allow you to set particular volume levels. The factory remote NEVER has all the codes.

However, adjusting the volume control, by hand or by IR, is the wrong approach. Moving coil cartridges have much lower output than moving magnet (that is, ordinary) phono cartridges. This lower voltage is preamplified or run through a transformer to bring it up to a level similar to that required by the phono cartridge input. And the output of that voltage raiser does go into the phono input, not a line input.

The Arcam AVR600 only has a Phono MM input so I'm using a VCR input and plugging the Clearaudio Phono preamp into that....On my IPad and can't copy the URL into the post. A google search of "arcam avr600 ir codes" gives some doc. I don't see one for setting the volume. I do have a serial rs232 box hooked to the receiver also for an IPad app. So I might be apple to send that command.

Experts?

Here's a volume set command...not sure how to do this via Q50

Output Command Specifications
Set/Request Volume (0x0D)
Set or request the volume of a zone.
This command returns the volume even if the zone requested is in mute. The
“Request Mute status” command can be used to discover if the zone is muted.
The data format for setting the volume is different depending on the zone being
set — Zone 1 is set in 0.5dB increments, Zone 2 & 3 are set in 1dB increments.
So, sending Set Volume data of 0x10 (decimal 16) corresponds to a volume of
8 for Zone 1, or 16 for Zone 2/3. To calculate the hex value required for setting
Zone 1 volume, multiply the decimal value by 2 then convert to hex.
Response data format: Data1.Data2
e.g. for volume 42.5dB: Data1=0x2A (42), Data2=0x05 (5).
Example
Command/response sequence for setting the volume in Zone 1 to 45.5dB:
Command: 0x21 0x01 0x0D 0x01 0x5B 0x0D
Response: 0x21 0x01 0x0D 0x00 0x02 0x2D 0x05 0x0D
COMMAND:
Byte: Description:
St 0x21
Zn Zone number
Cc 0x0D
Dl 0x01
Data 0x00 — 0xC6 – Set the volume
0xF0 – Request the current volume
Et 0x0D
RESPONSE:
Byte: Description:
St 0x21
Zn Zone number
Cc 0x0D
Ac Answer code
Dl 0x02
Data1 Zone volume, integer value:
0x00 (0) – 0x63 (99)
Data2 Zone volume, fractional value:
0x00 (.0)
0x05 – (.5) (Zone

If you can help me convert the above to an IRcode to set Zone 1 volume to 25db. I'd owe u beers

Rs232 serial commands and ir commands are two totally seperate animals. Just because a device can be controlled by both methods doesnt mean there is any correlation between the two. There might be ir commands to do the same function as the rs232 command you have listed but only the manufacturer can tell you for sure.

It says

Any operation that can be invoked using the IR remote control can be achieved over RS232 using the Simulate RC5 IR command (0x08). See page 7 for details of this command. The RC5 IR code set is listed from page 28.

So does this mean the above can set volume

"The" Clearaudio Phono preamp? I count four on their website. One is designed to raise MM or MC phono cartridge outputs to line level, which is the VCR audio level.  The ones that don't specify a type of cartridge are for MM only.

I'm guessing you don't have the unit that raises MC signals to the proper level.  By the way, given the cost of these, did you just have one lying around or did you actually pop for all that money just for this?  And did you tell them what you were trying to do?

....On my IPad and can't copy the URL into the post.
What URL?  The URL where you found the commands?  That's a pain but it can be typed unless iPads hide URLs.



Maybe.

So ok the manufacture has ensured that every command that is on the ir remote can be duplicated by rs232 control, but that doesnt mean every command possible by 232 control is thus also available as an ir command. It could be but also may not be.

got you...here's the document I'm looking at

[Link: google.com]

Say's

Simulate RC5 IR command (0x08). See page 7 for details of this command. The RC5 IR code set is listed from page 28.

So page 7

Simulate RC5 IR Command (0x08)
Simulate an RC5 command via the RS232 port. An additional status message
will be sent in most cases as a result of the IR command.
Example
Command/response sequence to RC5 16-17 (AVR volume down in zone 1):
Command: 0x21 0x01 0x08 0x02 0x10 0x11 0x0D
Response: 0x21 0x01 0x08 0x00 0x02 0x10 0x11 0x0D
COMMAND:
Byte: Description:
St 0x21
Zn Zone number
Cc 0x08
Dl 0x02
Data1 RC5 System code
Data2 RC5 Command code

And on page 13 says this is the set volume command for rs232

Set/request Video Output Resolution (0x13)
Set/request the Video Output Resolution of zone 1.
Example
Command/response sequence to request the video output in zone 1 where the
resolution is 1080p:
Command: 0x21 0x01 0x13 0x01 0xF0 0x0D

0x02 – Set resolution to SD Progressive.
0x03 – Set resolution to 720p.
0x04 – Set resolution to 1080i.
0x05 – Set resolution to 1080p.
0x06 – Set resolution to ‘Preferred’.

I'm just getting the impression I should be able to convert the SET VOLUME to an IR via the data they document...maybe not. I did use the IR codes at the bottom of the document for special cmds I wanted. But, I don't see a set vol in their IR codes.

It is the Clearaudio Plus that I bought as a demo. Has a switch on bottom for MC or MM. I do have a MC cartridge. Sounds beautiful
