View Full Version : Headphone connection on SB2

After waiting over 8 weeks for my SB2 (I'm in the UK) I too tested the headphone socket of my new unit after reading the thread below and guess what......my jack is faulty too! How many people are experiencing this problem? Are all the units fautly? I have just emailed tech support so we will have to see what they come back with. Has anyone got any further with this problem? I REALLY don't want to wait another 8 weeks just to get another one :-(

First thing I did was plug in a pair of PC desktop powered speakers into the headphones jack and found that there was a constant crackle and pop making it unusable. I'm in the UK also, although I don't think that should make a difference!

Yeah :-( I was just wondering if all unity shipped to the UK are faulty. I purchased mine from "multitaskccomputing" What have you done about this problem mmca22gr?

Also got mine from Multitask. Have not done anything yet so far as I was not planning to use the headphones socket that much. Think I will drop both Multitask and SLim Devices an email detailing the problem.

I received mine (in the UK) about 4-5 weeks ago. Headphones sound
fine, I tried a couple of pairs and both channels are crisp and noise
free.

I ordered my SB2 direct from SlimDevices, but I have the same problem (so it's not just a UK problem). In addition to the flaky headphone connection (which causes clicks, pops, and cutting out), I also hear an irritating (and relatively loud) fluttering sound between songs and within the first few seconds after the next song begins playing. I don't hear any of this over the RCA outputs.

It might be helpful for all the people with headphone jack problems to
post their MAC addresses, in case this issue can be isolated to a
specific production batch.

Good idea, mine are: 00-04-20-05-a8-ec and 00-04-20-05-a9-0d, both
producing audio on the left channel only of the headphone socket.

Just in case it's any use to the folks looking into this, my SB2 (wired) was bought in the UK through Broadbandstuff, and I did once get a slightly dodgy headphone connection, but I think the headphones may not have been properly plugged in. Apart from that the headphone connection has been fine. Its MAC address is 00:04:20:05:a1:37

On my (new) SB2, the right channel on the headphone jack appears not to work at all. My MAC address is 00:04:20:05:a7:ef.

Has there been any official comment on this headphone issue? The Slim staff seem to be somewhat quiet!

MAC Address: 00:04:20:05:A2:6A (Slim Devices)

I do not have problems with the headphone jack itself, it's a tight
enough fit and the channels are both there. There is about a seconds
of noise at the start of a song, though. It's a bit like the base
noise in a fax / modem connection.

Fair point. The issue has been discussed for longer than the last two days though.

Yep it is Sunday although do Slim Devices not provide tech support on a Saturday? I sent them an email as soon as I opened this thread - let's hope we get some response tomorrow as it seems like there are quite a few people with this problem......hmmmm.....not so good when you're paying 200. I'll also be calling "multitaskcomputing" my supplier in the UK tomorrow to see how they can help. In the meantime - my MAC address: 00:04:20:05:a9:6a

No problems using Phono/RCA outputs but still dodgy using PC speakers plugged into the headphones socket.
Player Firmware Version: 11
The ethernet MAC address for this player is: 00:04:20:05:a9:98
Wireless Signal Strength: 76%
Purchased: UK - multitaskcomputing

Hope this helps

If you're having headphone problems and need to have your SB2
repaired, please contact either Slim Devices support or your
reseller, depending on where you purchased it.

We've corrected a manufacturing error that affected some portion of
one production batch (R34, should be 20K but was not populated). The
exact MAC range of Squeezebox2s shipped with this issue is not known,
but the time-frame during which they shipped is limited to about a week.

RCA analog outputs and digital outputs are unaffected by this BTW.

Sorry for any inconvenience.

Sean,

is it possible to have details of the resistor spec and
placement position on the PCB? (Is it marked on the
silkscreen?)

I don't use the headphone outputs at all, so I'm not overly
bothered about getting them fixed right now. However, if I
ever did want to use them, or to sell my boxes on (say when
the SB3 is launched) I'd like to know how to do it.

I don't really want to go through the cost and inconvenience
of shipping the boxes back, and I suspect that you don't
really want this either.

Thanks,
Mark.

(BTW, I'm a qualified electronics engineer used to soldering
chips with very fine pitches, and most resistors pose no
problem at all!)

It's just a 20K, low-wattage, 0805 size, marked at R34.

Where is it? I can see R30-R33 and R35 clearly on
http://www.slimdevices.com/photos/inside_squeezebox2/4.jpg
but I can't seem to see R34. Is it hidden behind one of the big caps in
those photos?

It's the black one to the left of C58 - it's labeled but you can't
see the legend from this perspective.

On my (new) SB2, the right channel on the headphone jack appears not to work at all. My MAC address is 00:04:20:05:a7:ef.

Same here, MAC address 00:04:20:05:aa:12, purchased and used in England.

Regards,
Nick.

Just received 2xSB2 wired and 1xSB2 wireless from broadbandstuff.co.uk, and all have the missing resistor. I happened to have the right components to hand and added them and all works OK. On the last one I opened up I saw that there was a date sticker on the inside of the case showing a 15th March 2005 date - is this relevant?. I sense that the headphone output level is lower for the SB2 than for the SB1 it replaced - is this intentional?

Not relevant - that's the date stamp for the plastic itself.

[QUOTE]I sense that the headphone output level is lower for the SB2 than for the SB1 it replaced - is this intentional?

It may be a smidge lower - the output circuitry is completely different. For the headphone amp there is a tradeoff to choose between THD and max output level - we chose a slightly lower output level for lower distortion. You can crank it up as high as 3Vpp by modifying that op-amp's gain.
